Abstract

PURPOSE:To reduce local cooling of a rolled stock in a continuous hot rolling line by restraining a temp. drop of the stock caused by contact of the stock with inlet side pinch rolls with a heating means using burners. CONSTITUTION:Local cooling of a rolled stock by pinch rolls 9 is generated by sandwiching and fixing a preceding stock 8-1 with stopped pinch rolls 9 for a joining time of the preceding stock 8-1 and a succeeding stock 8-2; the pinch rolls 9 in a rotating state are continuously heated to a proper temp. with burners 10, 11. For a joining time, both the rolls 9 and the stock 8-1 sandwiched by the rolls 9 stop together and contacting points of the stock 8-1 and the rolls 9 are more heated. Hence, heat transfer from the stock 8-1 to the rolls 9 is markedly reduced and the temp. drop caused by the rolls 9 is sufficiently restrained.
