Abstract RU 2126302 C1

FIELD: rolling processes and equipment. SUBSTANCE: method is designed for rolling ready shapes of shaped blank with use of rolling aggregate having first universal stand at inlet side, second universal stand at outlet side and cogging stand between them. Cogging stand is arranged before group of rolling stands. Shaped blank is fed from continuous casting plant and it has at both sides bridges corresponding to ready thickened profile. Dimensions of shaped blank along height and(or) thickness of flanges are matched with dimensions of ready shape. Shaped blank is fed directly to first universal stand and then it is finally rolled to ready shape of predetermined size or it is rolled at reducing portions in the form of bridges and(or) thickened flanges of blank for receiving their size different from initial before introducing shaped blank into first universal stand placed in parallel with rolling line of rolling aggregate.
