Abstract: A control computer for a rolling train is supplied with prescribed stand parameters of a rolling stand of the rolling train. The control computer sets variables describing a rolling pass of the rolling stand that together with initial data of a flat piece to be rolled and the stand data describe the resultant roll nip and the asymmetry thereof. The initial data may be width, average thickness and average strength of the workpiece to be rolled. Based on the initial data, the stand data and the set variables an expected delivery taper and/or an expected strip sabre for the workpiece is determined. At least one of the set variables is manipulated to bring the determined delivery taper close to a desired delivery taper and/or the strip sabre close to a desired strip sabre. The manipulated variables are used to control rolling the workpiece piece.

Abstract: A method is described in which a length of hot rolled product is decelerated in the course of being passed through the rotating curved guide of a coiler. The product exits the coiler at a reduced velocity and is delivered to and progressively accumulated on a cylindrical drum as a helical formation of rings. The drum is rotated to continuously unwind the accumulating product at the reduced velocity. The tail end of the product is retained in the coiler until substantially all of the rings previously deposited on the drum have been unwound.

Abstract: A method of treating hot metal slabs (6) aims to reduce the width of the slab (6) produced by a continuous casting process to avoid the need for the prolific number of moulds otherwise required to produce slabs of various widths. In order to achieve this the hot metal slab (6) is presented, with its width dimension vertically oriented, to a pressing machine (24) having a vertically movable top platen (26) and a fixed bottom platen (28). The slab (6) is incrementally displaced, longitudinally, through the pressing machine and pressing forces are applied to its opposing edges by the platens, to reduce its width. Subsequently, the slab (6) is turned so that its width dimension is oriented horizontally and rolled between the horizontal rolls of a rolling mill (22). An apparatus for performing the method is disclosed.

Abstract: An apparatus for receiving the intermediate product of a rolling finishing mill. The apparatus incorporates an oven (40) to receive the intermediate product from the roughing stand (11) of a rolling mill. A first concave surface (16) of a deflector (13) directs the travel of the intermediate product from the roughing stand (11) to the oven means (40). Driven pinch rolls (36) selectively advances the intermediate product from the deflector (13) to the oven (40). Oscillating guides (44,45) within the oven (40) permit the intermediate product to be foldedly layered therein. When the intermediate product is substantially contained within the oven means (40) it is selectively secured at one end by clamp members (22,23) in a fixed position relative to the deflector (13).

Abstract: A processing line for rolling metal slabs into strip thicknesses along a substantially horizontal pass line includes the utilization of an intermediate mill formed of an upstream coiler furnace and a pair of coiler furnaces downstream of a reversing mill where the downstream coiler furnaces are in vertical alignment with one above the pass line and the other below the pass line. The method of rolling includes reducing a transfer bar in the reversing mill and coiling it in one of the downstream coiler furnaces. The coil is then passed back through the reversing mill into the upstream coiler furnace. Thereafter, the coil passes through the reversing mill for the third time and is again coiled in one of the downstream coiler furnaces. The coil is then uncoiled and directed into the finishing train while a subsequent coil is processed in the reversing mill utilizing the empty downstream coiler furnace. The rolling of the workpiece through the intermediate mill is done independent of the finishing train.

Abstract: A hot-rolling mill has a rough-rolling section and a finish-rolling section. These sections are transversely offset from one another and the end of the rough-rolling section is connected to the beginning of the finish-rolling section by a heating station. Within the heating station, at the end of the rough-rolling station, is mounted a take-up coiler for the rough product. This coiler can transfer its product coil to a pay-out coiler which is either movable transversely between the two sections so that it can move to the second path and feed the product into the second or is fixedly mounted at the beginning of the second (finish-rolling) section in which case a transporting device is provided which transports the coils from the take-up coiler to the pay-out coiler.

Abstract: A rolling line for billets, bars, wire rod or the like, e.g. a roughing line has one or more rolling stands each having three or more driven rolls which are adjustable towards and away from the work material by a worm drive and a screw. The rolls are brought progressively closer together before each pass of the work material, whose cross section is thereby reduced with corresponding elongation. The direction of rotation of the rolls is reversed between each pass, unless two stands for rolling in opposite directions are provided in which case it is possible for the stands to be continuously driven but alternately operative. The work material is turned about its axis through half a roll pitch angle between each pass.
