Abstract

PURPOSE:To perform temper rolling of a rolling stock of hard metal or a stock required to give priority to surface gloss and surface shape, and to improve the productivity by exchanging an assembly of multiroll cluster mill and that of two-high mill for each other by using the same stand. CONSTITUTION:A roll assembly 8 for a multiroll cluster mill and a roll assembly 7 for a two-high mill are easily exchanged for each other by using a rearrangement device. In case of temper rolling a hard material such as a hard stainless steel sheet or a high-strength steel sheet, for instance, a multiroll cluster mill having small-diam. work rolls excellent in sheet-shape controllability and suitable for high rolling-reduction rolling is used to obtain a rolled product having desired elongation rate and a prescribed shape. Further, in case of temper rolling a rolling stock such as an ordinary stainless steel required to give priority to surface gloss and sheet shape, a two-high mill having large-diam. work rolls is used to obtain a rolled product having expected surface gloss and sheet shape. That is, by using the same stand 2, a rolling stock having properties of wide range, such as a hard steel or a stock required to give priority to surface gloss and sheet shape is temper-rolled.
