Abstract: A wheel apparatus is provided for measuring by rolling contact a dimension of an elevated temperature surface. The device is particularly useful for measuring the length of product in a continuous casting machine. The apparatus includes an elongated arm having an internally cooled wheel rotatably mounted at one end thereof. The arm is pivotally movable about a mount at an end of the arm opposite from the one on which the wheel is mounted. The mount biases the arm to a position in which the longitudinal axis of the arm is normal to the adjacent surface of the cast product. The biased mount permits pivotal deflection of the arm upon contact of the wheel by cast product moving in either a forward or reverse direction. The arm has at least one longitudinal cooling fluid passage which only registers with a cooling fluid supply passage in the arm mount when the arm is in the deflected positions thereof. Generally, air is supplied through the mount to cool the arm and outer surface of the wheel.

Abstract: A steel strip is first passed longitudinally in a predetermined travel direction through a nip between a pair of parallel rolls, and then passed downstream in the direction from the rolls over a sensor that engages the strip at a plurality of zones spaced apart on the strip transverse to the direction. The sensor generates respective output signals corresponding to the deviations from planarity of the strip at the zones. A treatment liquid is sprayed uniformly and at a relatively high temperature on the rolls while respective streams of a coolant liquid at a relatively low temperature are directed at regions of the rolls corresponding to the zones. The heat exchange between the streams and the rolls is varied in accordance with the respective output signals to thermally change the diameters of the rolls in the respective regions and thereby eliminate the deviations in planarity detected by the sensor.

Abstract: Disclosed is a high-efficiency manufacturing installation in which seamless steel pipe rolling and finishing lines are matched in capacity with each other and are formed into a single continuous lines.The high-speed rolling line extends to a straightening machine via a cooling equipment for as-rolled pipes and a heat treating equipment for pipes to be heat-treated and is further connected to a single-line finishing line via a nondestructive inspection machine and a cutting machine. The finishing line comprises each plurality of different finishing machines arranged along a variable feed pitch transverse transfer line, the plural number being selected in correspondence to the capacity of the rolling line. The cooling equipment and the heat treating equipment are designed so that each of them requires the same transfer time and thus there is no danger of causing any blank in the feed pitch spacing during the change-over between the as-rolled pipes and the pipes to be heat-treated.

Abstract: A rolling stand has a conventional housing defining a pair of parallel and spaced axes defining a plane. Respective rolls have roll ends journaled in the housing at the axes and roll bodies axially symmetrical about the respective axes and having centered on the respective axes complementary roll-body surfaces of noncylindrical shape and each formed by rotation of a continuously curved generatrix about the respective axis. One of these contoured rolls is displaceable axially relative to the other roll from an end position to another position, and the roll-body surfaces form at the plane in the other position a uniform nip and in the end position a nonuniform nip. This system is set up to be able to displace one of the rolls axially relative to the other of the rolls between the end position and the other position. These contoured rolls may themselves define the nip, or may engage and deform other rolls that define it.

Abstract: A controlled cooling apparatus for a wire rod coiled into loops immediately after hot rolling. The coiled wire rod is transported with the loops laid substantially flat with a space of a given pitch from one another on a cooling bed. Nozzles are provided to project a cooling fluid such as forced air from below the cooling bed at an angle of from 40.degree. to 140.degree. with respect to the plane of the cooling bed to cool the coiled wire during its transportation. The nozzles are open in a transverse direction of the cooling bed with a nozzle opening area ratio of from 0.8 to 1.2, to provide uniform distribution of the cooling fluid in the transverse direction, whereby uniform cooling can be accomplished to minimize the variation in the cooling rates at densely overlapped loop portions and at sparsely overlapped loop portions.

Abstract: A roller is shown having an apparatus for cooling or heating the roller surface. The apparatus has essentially one or more chambers which are open relative to the roller surface. The chambers have a substantially square internal cross section. A fluid is fed in through the inlet ducts. During operation of the roller turbulence is formed in the chambers. The turbulence results in a longer retention time for the fluid in the chambers thus producing a greater cooling or heating effect for the amount of fluid fed in.

The equipment for each guide (17, 18) consists of a coolant manifold (25, 32) formed within the guide structure and a communicating curtain-discharging nozzle (30, 36) which is recessed in the guide plate (21, 22) and which extends over almost the entire length of the guide. The manifold (25, 32) is supplied with coolant through pipes (26).

Abstract: While liquid coolant in the form of pressurized sprays is being delivered onto the upstream sides of the working rolls in a rolling mill across the width of the moving metal strip, pressurized fluid jets are directed against the opposite end portions of the working rolls outwardly of the longitudinal edges of the strip, said jets being aimed axially outwardly toward the ends of the working rolls and somewhat upwardly and downwardly in relation to the top and bottom faces of the strip. Closely beyond the downstream sides of the working rolls, additional pressurized fluid jets are directed downwardly and upwardly against the moving strip with the air concentrated near its longitudinal edges to dislodge any remaining coolant.

Abstract: Process and apparatus for the cold rolling of ferrous metal or nonferrous metal strip, e.g. steel or aluminum strip, in which the strip is passed at a high rate through a multiplicity of cold rolling stands and a coolant is dispensed from nozzles directed against the rolls or the band in the region of the rolling gaps. According to the invention, the planarity of the strip is measured immediately downstream (in the direction of strip movement) of the last rolling stand and deviations from planarity are determined and converted into control signals. The planarity measurement signal is compared with a deviation-maximum signal processor until the measured deviation reaches a first threshold within the range to maximum. Only the coolant spray from the nozzles of the last stand are controlled in a planarity-restoring sense. When the measured deviation exceeds this threshold at least the nozzles of the penultimate stand are controlled.

The roll pair further is characterized in that the side plates (16) on opposed sides of said roll package are arranged to take up roll forces via two end members (18), and that the roll package is arranged so as directly and/or indirectly to rest against the end members (18).A further characterizing feature is that said end members (18) are arranged so as to permit adjustment of the roll distance, so-called roll gap adjustment.

Abstract: At the end of a hot-rolling train, a metal length (bar or wire) is passed through a final roll stand and then through a cooling device. To keep the length under tension in the cooling device, it is pulled frictionally by an opposed pair of bridle rolls which are driven, while the length is passing, with a power input which would, in the absence of the length, be sufficient to cause a peripheral speed of the bridle rolls slightly higher than the rolling speed of the length. To prevent the leading end of the metal length being twisted or otherwise damaged on entry into the bridle rolls, the bridle rolls are driven at a slightly higher peripheral speed immediately prior to the entry of the metal length.

Abstract: A multi-stand rolling mill is operated so that strip of suitable shape and metallurgical properties is produced at a faster speed than possible heretofore by threading the mill at a relatively slow speed and adjusting the rolling loads on the stands to give the required output gauge and rolling temperature at the last stand, thereafter the mill is accelerated and curtains of liquid coolant are applied to the workpiece at one or more interstand locations to ensure that the rolling loads remain substantially the same as when threading and the rolling temperature of the last stand remains substantially constant.

At least one of the squeeze rolls is a controlled deflection roll.

Abstract: A cooling conveyor arrangement for rolled wire or wire rod which has left a water cooler has a loop-forming device which deposits the wire in overlapping loops on an air-cooling conveyor. To obtain a shorter cooling path, which is desirable for high-grade steels to reduce the rate of cooling, the loops fall onto a conveyor portion and are carried by a conveyor portion to a coil-forming station where the loops are collected. To obtain a longer cooling path a removable conveyor portion is switched into place so that the loops are carried along a conveyor portion to an opening where they fall onto a conveyor portion. A conveyor portion is swung into alignment with the portion carrying the loops to feed the loops to the coil-forming station.

In order to maintain the line in continuous operation and in order to distribute the severed cooled strands to the subsequent bundling apparatus, the arrangement herein provides for dual conveyors each preceded by its own laying tube and a switch for selectively feeding the strands to one or other of the conveyors. By controlling the speed of one relative to the other of the dual conveyors, the strands may be selectively converged in even distribution for subsequent processing. The dual conveyors may be side by side or superimposed one above the other. With the latter arrangement, the upper conveyor may be mounted to pivot into and out of the line of the lower conveyor for the sequential feeding of the coils to the following line.

The product to be cooled passes through the tube either in the same or in a direction opposite to the direction of flow of cooling fluid through the tube. At least one centralizing element is provided in the tube spaced from the opposite ends of the latter and having a central passage coaxial with the tube and a diameter smaller than that of the tube for the passage of the product therethrough, and a plurality of channels uniformly distributed about the central passage to facilitate flow of cooling water from one to the other end of the tube.

Abstract: A workpiece issuing from a rolling mill is directed by a tubular guide to pass above the knives of a flying shear that is driven in a drive train used to rotate a cam used to pivot the guide tube and direct the workpiece into the shear. The workpiece moves beyond the shear into one of a plurality of retardation channels formed in a drum. There may be shock absorbers at their remote ends to prevent escapement of the sheared workpieces in the event they fail to stop by sliding friction. The drum rotates at a relatively slow speed. When a trailing end of a sheared workpiece moves beyond the shear into the drum, the leading end of the remaining length of workpiece enters a laterally-adjacent channel which has moved into the path of travel by the workpiece through rotation of the drum. A conveyor receives workpieces discharged from the drum through rotation thereof and carries them to a remote discharge station where they are loaded into a cradle car.

Abstract: A method for controlling the temperature of a workpiece in a hot strip mill includes calculating temperature changes of the strip at each mill stand location by determining changes in workpiece deformation resistance and correlating the changes in deformation resistance to changes in temperature. Error corrections are made for changes in rolling speed. The calculated temperature change at each mill stand is used to control water sprays positioned adjacent the mill stands. A temperature sensor is placed downstream of the last mill stand to act as a check on the desired delivery temperature of the workpiece. Temperature discrepancies from the temperature sensor are fed upstream to modify temperature corrections.

Abstract: The invention relates to a process for automatically controlling the shape of sheet metal produced in a rolling mill, and to apparatus for carrying out the process. The shape of the sheet is sensed by a shapemeter, and each segment of the shapemeter provides an output indicative of the shape of the portion of the sheet passing over that segment. In accordance with the invention, the outputs are converted to electrical signal levels, such as current or voltage levels, and certain ones of the signal levels are averaged, and the averages are compared either with certain other signal levels, or with certain other averages. If the comparisons yield a difference greater than predetermined tolerance levels, control signals are generated to control parameters of the rolling mill.

Abstract: The invention refers to a spray nozzle arrangement for metal strand casting plants, particularly steel strand casting plants with several nozzles on one spray plane, such nozzles being adjustable with respect to the distance from the casting strand, and with each other in parallel direction; they are also adjustable at right angle with the course of direction of the strand by means of parallel adjusting devices. Adjustment of the spray nozzles serves the purpose to either control the cooling intensity via the impact energy, or to adapt the spray angle of a certain spray nozzle to a change in strand width. Both steps may be used in combination for the adjustment required.

Abstract: Metal strip reducing rolls are precisely cooled in multiple zones across the width of the strip by the selective activity of modular valve assemblies on coolant headers mounted near the reducing rolls. Each valve module may possess one or more remotely controllable coolant control valves within the header and associated coolant nozzles whose aperture sizes may vary in a fixed ratio within each zone to achieve a variable coolant flow rate in each zone while maintaining a constant unchanging coolant spray configuration and impingement force. Individual coolant valves and nozzles in a digital control system are fully on or fully off in contrast to gradient control of coolant in an analog system. An observer of the moving metal strip activates and deactivates selected nozzles in selected zones across the strip through a push button digital control console. Electrical, pneumatic or hydraulic valve control may be utilized. Back-up rolls in the mill may also be cooled.
