    Abstract: A flat rolling stock is first rolled in a rolling mill from an initial thickness to an intermediate thickness, and then from the intermediate thickness to a final thickness. In order to roll the rolling stock from the initial thickness to the intermediate thickness, a number of reduction stages is determined and the rolling stock is rolled accordingly. Further, a permissible thickness range for the intermediate thickness is set using technological boundary conditions. The reduction stages are determined such that the intermediate thickness is within the permissible thickness range and either the performance limits of the rolling mill are completely utilized in every reduction stage, or not completely utilized in at least one reduction stage; however, in the event that the number of reduction stages were reduced by one, the intermediate thickness would be outside of the permissible thickness range, although the performance limits of the rolling mill would be completely utilized for all reduction stages.

    Abstract: An optimizing method for improving the efficiency of production is provided for a steel rolling mill using a Steckel mill to roll steel slab to end-product thickness, and associated downstream equipment of limited capacity to generate strip and/or plate end-product. The optimizing method allows for continuous processing of steel slab of a mass within the capacity limits of the Steckel mill and equipment upstream of the Steckel mill, but in excess of the capacity of the associated downstream equipment, by first rolling the slab in the Steckel mill to intermediate coilable thickness, and then severing the intermediate steel product to produce two derivative segments, one of a target mass within the limit of capacity of the coiler furnaces and downstream equipment, and another, typically smaller, residual segment. The residual segment is disposed of, optionally first milled to end-product thickness in the Steckel mill, and transferred to conventional downstream equipment. In the meantime, the target segment is held within a coiler furnace. The target segment is subsequently milled and finished to end-product thickness. The method improves the efficiency of production in a steel rolling mill.

    Abstract: The present invention relates to a method of controlling the productivity of a rolling plant having at least first and second rolling stands by processing a single slab of metal having a thickness, into metal strips having different thicknesses less than the thickness of the slab in accordance with strip output requirements of the rolling plant. The output requirements for strips having at least first and second different thicknesses to be produced by the rolling plant is determined. The slab is then rolled in a first rolling stand to reduce the slab thickness to produce a transfer bar. The transfer bar is sheared into first and second transfer bar portions such that the first and second transfer bar portions are sized to correspond to the output requirements for the first and second strips, respectively. The first transfer bar portion is then rolled in one of the first and second rolling stands to reduce the first transfer bar portion to produce a first strip having a first thickness.

    Abstract: A frame carrying one or more transducers is inserted between the work rolls of a mill stand with the transducers positioned parallel to the roll axis. The outputs of the transducers are connected to a display device which when load is applied to the rolls displays the several output signals side-by-side so that variation in loading lengthwise of the rolls is made visible. The outputs of the transducers may also be interconnected with automatic gauge and crown control circuits so as to calibrate those circuits.

    Abstract: Incoming and outgoing plate-thickness deviations for the same point of a sheet passing through a reduction rolling mill are determined for a plurality of rolling speeds so as to calculate the outgoing plate deviation component attributable to the inherent characteristics of the rolling mill upon deceleration and acceleration, such as changes in the oil film and in the coefficient of friction. The thus determined outgoing platethickness deviation component is stored as information corelated to the speed at which it was determined, so that it may be selectively retrieved to be applied as a correction factor in the screw-down of the rolls upon automatic operation at the corresponding speeds of subsequent roll passes.
