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.
