Abstract: A chill block melt spinning apparatus produces flake-type powder of the smallest magnitude by centrifugal disintegration of molten metals and alloys. Molten metal or alloy is delivered to a rotating cup which centrifugally forces the metal to exit the cup tangentially in a sheet which breaks up into streams and then into a series of droplets. Rotating chill cylinders are radially spaced from the rotating cup. The cylinders receive the streams or droplets of semi-solidified metal and provide a fresh surface for each droplet to chill the droplets, forming ultra fine flakes while deflecting the flakes downward into a collecting area. The cylinders have a concave outer surface which corresponds to the shape of the rotating cup to provide an equidistant travel path from the rotating cup to a deflection contact surface for the radially travelling droplets.

The surface of each roll is divided into at least three circumferential zones, at least one (5) of said zones having a roughness (Rz) greater than the roughness of the other zones (6). This device permits carrying out the process according to the invention in which solely certain longitudinal zones of the skins of cast metal solidified on contact with the cooled walls of the rolls are preferentially driven along.

Abstract: A two part, integrated melt overflow pouring apparatus including a hearth which contains molten material, and a spout which is stationary with respect to, and transfers the liquid to, a rotating, heat extracting substrate such as a drum. A hinging body such as a cylinder connects the hearth and the spout and allows the hearth to rotate with respect to the spout. A channel is formed in the cylinder and an equal width channel is formed in the spout. The floor of the channel in the hinging body is at a 45.degree. angle with horizontal initially and rotates when the hinging body rotates. The hearth is rotated about the axis of the hinging body, the molten material flows out of the hearth through the channel in the hinging body, through the channel in the spout and solidifies against the drum.

Abstract: The roll comprises a core (6) and a sleeve (7) in which latter are provided ducts (8) for the circulation of a cooling fluid. According to the invention, the sleeve (7) is rigidly connected to the core (6) in its axially median part and substantially throughout its circumference by an assembly which prevents any axial and radial displacement in this median part of the sleeve relative to the core, such as a dovetail assembly (9, 10) or a T-way assembly. The sleeve is in contact with the core throughout its width and is maintained by its edges (7', 7") on the core by maintaining means (11, 12, 13, 14) which allow an axial displacement but prevent a radial displacement of the edges of the sleeve relative to the core.

Abstract: A casting system for casting molten metal into a continuous solidified strip. A source of molten metal is fed onto a tundish which is interposed between the source of molten metal and a continuous substrate system preferably in the form of a continuous belt. The tundish directs the molten metal onto the moving belt in a direction toward the upstream end thereof so that it is moving in a direction opposed to the direction of the belt. This method of feeding the melt onto the belt results in less turbulance, a dampening of the molten metal and a spreading of the material across the width of the belt.

Abstract: An apparatus for continuously making an amorphous metal strip used, for example, as a blank for a voice magnetic head, deposits molten metal from a nozzle onto the surface of a cooling roll under a fixed pressure and while the cooling roll rotates, the molten metal is rapidly cooled and solidified on the cooling roll. A rotation speed control adjusts the rotation of the cooling roll so that the speed is gradually reduced during the manufacturing process. The nozzle may be provided at an angle to the surface to the cooling roll with the nozzle opening opposing the direction of rotation. Alternatively, the nozzle may be provided perpendicular to the surface and off the center access of the cooling roll opposite the rotating direction of the cooling roll. In this embodiment, the tip of the nozzle is shaped with an angled opening. Moreover, the surface of the cooling roll may have a roughness greater than a mirror-smooth surface.

Abstract: A method and apparatus for the casting of metals in which a molten stream of metal is atomized into a spray of highly liquid droplets. The droplets are deposited on a moving substrate such as an endless belt provided with side dams. The droplets flow in a direction transverse to the direction of movement of the substrate and are contained by the side dams. The droplets may have an average size of 300 microns and the spray may have a liquid to solid ratio of at least 50%. This arrangement overcomes the problems of splashing and turbulence caused by the relative flow between the melt and the belt in regular belt casting and overcomes porosity problems associated with spray casting.

Abstract: The surface of each roll (2, 3) has a knurling constituted by two series of parallel grooves (5, 6) which are inclined to the axis (XX) of the roll and joining up at the center of the latter so as to form a series of chevrons, the two grooves (5, 6) of each chevron downwardly converging when they are on the side of the roll (2, 3) in contact with the liquid metal. The device is completed by a cage for extracting the cast product at a speed slightly higher than the speed of rotation of the casting rolls (2, 3). This arrangement avoids the formation of longitudinal or transverse cracks on the surface of the cast thin metal strip.

Abstract: The continuous casting of metal strip using the melt overflow process is improved by controlling the weir conditions in the nozzle to provide a more uniform flow of molten metal across the width of the nozzle and reducing the tendency for freezing of metal along the interface with refractory surfaces. A weir design having a sloped rear wall and tapered sidewalls and critical gap controls beneath the weir has resulted in the drastic reduction in edge tearing and a significant improvement in strip uniformity. The floor of the container vessel is preferably sloped and the gap between the nozzle and the rotating substrate is critically controlled. The resulting flow patterns observed with the improved casting process have reduced thermal gradients in the bath, contained surface slag and eliminated undesirable solidification near the discharge area by increasing the flow rates at those points.

Abstract: The continuous casting of strip, ribbon and wire is improved by using a free jet nozzle which provides a fluid that follows a rotating substrate surface to the separation point. The nozzle includes an inclined surface having a ratio of its length to the gap between the substrate and the nozzle edge of 5:1 to 15:1. The inclined surface improves the ability of the jet to tangentially follow the substrate in a direction opposite to its rotation to the separation point. This also allows a close positioning of the nozzle to the substrate which serves to provide a back-up mechanical separation means by using the edge of nozzle lip. The nozzle may be rotated from its operating position for cleaning of the substrate and the nozzle.

Abstract: The flow control of molten alloy material in a tundish is improved by the design of a perpendicular turn in the path of flow of the molten alloy material as the flow leaves an intermediate section of the tundish or casting receptacle and overflows transversely an exit lip to thereby contact a heat-extracting substrate. The perpendicular turn in the flow achieves improved control of the molten alloy material's velocity profile, cooling rate, and depth and flow uniformity of the molten alloy material in the casting receptacle. The essentially perpendicular turn in the path of the molten alloy material from the intermediate section causes the molten alloy material to approach the exit lip in a transverse direction unlike conventional laminar or direct delivery molten flow.

Abstract: The flow control of molten material in a tundish is improved by the design of a perpendicular turn in the path of flow of the molten material as the flow leaves an intermediate section of the tundish or casting receptacle and overflows transversely an exit lip to thereby contact a heat-extracting substrate. The perpendicular turn in the flow achieves improved control of the molten material's velocity profile, cooling rate, and depth and flow uniformity of the molten material in the casting receptacle. The essentially perpendicular turn in the path of the molten material from the intermediate section causes the molten material to approach the exit lip in a transverse direction unlike conventional laminar or direct delivery molten flow. The transverse flow relative to the direction of the exit overflow toward the casting or cooling surface facilitates improved mixing of the molten material, improved control of the depth gradient, and improved control of the velocity into the exit lip.

In one embodiment, inlets (21a, 21b) are alternated on the same side of the shell with outlets (22a and 22b) of adjacent channels so that the cooler regions around inlets and alternated with higher temperature outlet regions to balance the temperature around the surface.

Abstract: A molten metal spray-depositing apparatus employs an ejection nozzle for receiving a molten metal stream and having a configuration for confining and imparting mechanically an angular momentum thereto which produces stream break-up into a metal particle spray when the stream becomes unconfined upon exiting the nozzle. There are stationary and rotating versions of the ejection nozzle. The stationary ejection nozzle has a flow channel with internal angular elements, such as spiral grooves, which engage the moving molten metal stream to impart angular momentum thereto as it passes through the channel. The rotating ejection nozzle may have internal elements within the flow channel, such as notches or serrations, which engage the moving molten stream and cause it to rotate with the nozzle as it passes through the channel. The two nozzles can also be combined to impart the angular momentum and accomplish melt stream break-up.

Abstract: In rollers, especially those used for continuous casting of strips (40) of aluminum and other metals, the coolant flows between the roller shell (7) and the roller core (8) through axial cooling channels (26). The counterflow principle is here applied, so that the coolant alternatively flows in the cooling channels (26) from one front side (41, 41a) to the other and is discharged there. A bore divided into an axial channel (15) and into a tubular channel (16) for supplying and discharging the coolant extends from one front side of the roller (1) to the other front side. Alternating supply and discharge ducts for the cooling channels (26) that extend over the whole length of the roller core (8) are arranged in such a manner near both roller front sides that the coolant flows according to the counterflow principle. The cooling channels (26) are formed of longitudinal grooves in the core (8) and shell (7) of the roller.

Abstract: Continuous production of metal fiber is provided by delivering molten metal at low pressure to a multi-edged, rotating casting drum.

The flow to the orifice is controlled by means of a constrictive channel upstream of the orifice communicating with the source of molten metal.

Abstract: A method and system is used for achieving increased precision of steering of the flexible, metallic endless belts of continuous metal-casting machines. Such belts usually have the imperfections inherent in the parent strip metal from which the belt is made. For example, in low-carbon steel, there is generally a "camber," a curvature of the edges in the plane of the strip material. Belts, revolving in the machine, are normally steered through sensing the lateral position of one edge. If the edge is not true, due to camber, the servo steering system of the prior art will continually "hunt" caused by variations in lateral position of the cambered edge. The present invention provides a steering method and system responsive to a single signal source, fixed on a belt edge. This single signal source is achieved by notching or otherwise cuing a belt at one place along an edge so that the steering sensor senses this cue notch as the belt revolves.

Abstract: A molten metal gas-atomizing spray-depositing apparatus has an atomizer which employs a pressurized gas flow for atomizing a stream of molten metal into a spray pattern of metal particles and for producing a flow of the particles in the pattern thereof along with the pressurized gas flow in a generally downward direction. The apparatus also has a substrate, such as composed of stainless steel, disposed in spaced relation below the atomizer with at least an upper surface layer of a glass thereon, being thermally softenable over a broad predetermined temperature range. The pressurized gas flow impinges on the glass surface layer of the substrate which receives a deposit of the particles in the spray pattern to form a product thereon.

Abstract: Apparatus for continuous casting includes a tundish for containing molten metal and delivering the metal to a work zone where the metal solidifies as it is moved through the work zone in a continuous casting process. The tundish contains molten metal and includes an outlet and a pervious flow restricting element is positioned in the outlet. The element causes the flow of the metal to be distributed as it flows through the outlet and into the work zone to engage a growing shell of solid metal carried through the work zone by a chilled substrate. The molten metal acts to apply a pressure on the shell and to lubricate the moving shell. The arrangement minimizes exposure of liquid to air and minimizes opportunity for turbulence in the liquid contained in the work zone. A method of continuous casting is also described.

Abstract: A molten metal gas-atomizing spray-depositing apparatus has an atomizer employing a pressurized gas flow for atomizing a stream of molten metal into a divergent spray pattern of metal particles and producing a flow of the particles in the pattern thereof along with the gas flow in a generally downward direction. The apparatus also includes a substrate movable continuously along an endless path and having an area thereon disposed below the atomizer for receiving a deposit of the particles in the spray pattern to form a product on the substrate being substantially uniform in thickness. The endless path of the substrate is generally elongated in the downward direction and thus extends parallel to the general downward direction of gas flow such that any particle overspray past the deposit-receiving area is carried by the gas flow downward past the substrate, substantially avoiding entrainment of the particle overspray in the product being formed on the substrate.

Abstract: A molten metal gas-atomizing spray-depositing apparatus has an atomizer which employs a pressurized gas flow for atomizing a stream of molten metal into a spray pattern of semi-solid metal particles. The apparatus also has a movable non-preheated substrate composed of a material having a predetermined thermal conductivity of about one or less (W/M-K) being disposed below the atomizeer. The substrate receives thereon a deposit of the particles in the spray pattern. The pressurized gas flow also impinges thereon for cooling the deposit on the substrate to form a product thereon. The predetermined thermal conductivity of the substrate of one or less precludes extraction of heat by the substrate from, and thus solidification of, the deposit upon initial contact with the substrate whereby a reduction of porosity is achieved in the deposit.

Abstract: In a process for casting strip and foil, a melt from a casting slit (4) of a casting nozzle (3) is applied to a moving cooling body (6). The melt is thereby diverted in a gap (A) from the flow-out direction out of the casting slit into the strip removal direction. In order to improve the casting conditions and the strip quality, but also to be able to produce larger cast formats, especially a multiplication of the produceable strip width and a simplification and cheapening of the melt feed device to the cooling body, the melt is fed in the casting nozzle (3) up as far as the entry into the casting slit (4) perpendicular to the casting direction and perpendicular to the strip removal direction (21). In the region of the casting slit within the casting nozzle, a diversion of the melt into the flow-out direction is provided for.

Abstract: This invention relates to an apparatus for producing filament, fiber, ribbon or film from a molten material, comprising a preferably heat extracting crucible which contains a pool of molten material at a selected horizontal level in the pool.

The substrate is positioned adjacent the edge of the opening which confines the molten material and prevents it from overflowing downwardly out of the crucible.

Abstract: A smooth roll skimmer 36 may be used in the casting of strip 34 by the melt drag process to provide gauge control and a smooth upper surface. Liquid melt 32 is cast on the moving chilled substrate 33 where it solidifies to a strip. The skimmer 36 is positioned above the substrate 33 and at a fixed gap therefrom by convenient means, e.g., by a rolling spacer 37 between the casting surface and the roll skimmer. The roll skimmer is not chilled and is not used to solidify the liquid. It meters and smooths the liquid prior to solidification on the substrate. A parting agent may be used on the roll skimmer to prevent sticking and to reduce heat transfer. A carbonaceous soot from a partially combusted hydrocarbon fuel is a useful parting agent.

Abstract: In a process for casting metal strip, in particular steel strip, the liquid metal is discharged from a casting nozzle which has the same width as the strip onto a continuously moving, cooled conveyor belt, and the plane of the nozzle mouth is set for the thickness of the metal strip to be cast, i.e. at an acute angle to the plane of the conveyor belt. To maintain the casting speed at the nozzle mouth on the conveyor belt, i.e. to prevent shearing forces of the flow layers and thus a speed profile with negative components, the invention proposes that with a conveyor belt running at an inclination to the horizontal in the casting direction, the inclination of the conveyor belt in the casting direction is set as a function of the casting speed, which should be equal to the conveyor belt speed, and as a function of the material parameters of the liquid metal.
