Abstract: A continuous casting installation comprises an ingot mould and an oscillating holding device used for causing the ingot mould to swing when in a casting position. The installation consists, in a separable manner, of an interchangeable part and a stationary part. To replace the intechangeable part, it is separated from the stationary one and moved using a conveying means, at least along a partial path, from its position of operation into an area beneath the casting position. This enables, especially in the multiline casting installations, the interchangeable part to be transported during the casting process and, for example, along paths comprising straight or arciform segments, to any purposefully selected position and to be replaced by a new interchangeable part to be replaced in multiline installations with no interference with the casting process in any adjacent ingot arrangement.

Abstract: An important liner for use in a continuous casting machine includes the conventional hot face surface, cold face surface, and at least one coolant interface area, such as the bottom of a cooling clot that is machined into the liner. Advantageously, the coolant interface area is configured to have a shape along at least a portion of its length that differs from the simple planar shape that is usual for such areas. This shape could include a fin that projects from the coolant interface surface, a corrugation, or other shape. As a result of this configuration, the surface area of the coolant interface area is maximized, thereby promoting enhanced heat transfer through the liner at a portion of the liner that is proximate the coolant interface area. This configuration can be placed selectively at certain areas of the mold that are felt to need increased thermal conductivity, such as near the meniscus area, and in areas where premature mold wear or cracking have been observed due to thermal stresses.

Abstract: A roll for use in a roll caster. The roll has a heat exchanger core and an outer generally cylindrical shell surrounding the core, the core and the shell defining an enclosed space. A working fluid is contained in the enclosed space. When molten metal is cast onto the shell, the working fluid in proximity to the outer shell changes from a liquid to a vapor. Due to the rotation of the roll, the liquid phase of the working fluid forces the vapor in proximity with the outer cylindrical shell to return to the area adjacent to the core. At this area, the vapor phase is condensed into a liquid which is then subsequently delivered radially to the outer cylindrical shell. In this way, the working fluid constantly changes from vapor to liquid and back to vapor again and acts to continuously remove heat from the molten metal cast onto the outer cylindrical shell. A single roll caster, a twin roll caster, and a melt spinning apparatus as well as an associated method are also disclosed.

Abstract: An improvement in systems for continuous casting steel to near net shape sheet or plate directly from molten metal. This is accomplished by floating the liquid steel on a liquid substrate of silver, allowing it to solidify and withdrawing a continuous section of thin, wide steel. Liquid to liquid casting, by eliminating the mechanical problems of thin sheet casting with wheels or belts, allows for increased tonnage rates. For example, aiming at a thickness of 3 mm. by a width of 1500 mm., a liquid steel to liquid silver caster in continuous production at 200 feet per minute will produce 750,000 tons per annum. Increased cast speeds and/or multiple lines due to simple construction seem practicable for greater tonnage. Only liquid silver, as a float medium, makes high quality float casting of molten steel possible.

Abstract: An apparatus and method for producing a rapidly solidified ingot characterized by a fine scale microstructure capable of precipitating uniformly dispersed fine particles. A charge of the material is placed in a crucible and heated by a furnace to melt the charge. The melt is discharged from the crucible in a stream along a pouring axis. An ingot mold is oriented at an angle with respect to the pouring axis so that the stream is received in the mold. As the melt is being poured into the mold, the mold is rotated about its central axis at a predetermined speed to continuously shear, both circumferentially and downwardly, a thin layer of the melt from the stream as the stream contacts the sidewall surfaces of the mold. The thin layer is rapidly solidified by the extraction of heat through the mold and is formed, as said ingot mold fills and successive layers are solidified, into an ingot having a fine microstructure capable of developing uniformly dispersed fine particles.

Abstract: The invention discloses a method and apparatus for horizontal continuous casting of thin steel slabs by floating liquid steel on the surface of a pool of molten lead and allowing the steel to solidify by cooling to form a continuous flat ribbon. The virtually complete immiscibility between iron and lead is the key to the invention and also the fact that iron floats on lead, both are good heat conductors and molten lead is non-wetting towards solid iron and a good lubricant for it. The method is conducted in an elongated tray containing a molten lead pool and incorporating lateral edge dams defining the cast slab width. Liquid steel from a prior process is continually introduced from a tundish or ladle and distributed uniformly across the entry end while avoiding turbulence and mechanical mixing between lead and steel. Heat is extracted by external cooling as the steel progresses along the tray, causing it to freeze and form an outer shell solidification front extending transversely between the edge dams.

The cooling channels (26) are formed of longitudinal grooves in the core (8) and shell (7) of the roller.
