EQUIPMENT FOR HOT ROLLING

摘要

PROBLEM TO BE SOLVED: To exactly calculate a point of time when a succeeding material is extracted from a heating furnace for catching up with a preceding material in the target catching-up position on the hot rolling line from the pattern of conveying speed of the preceding material and the succeeding material until the completion of catching up after the extraction from the heating furnace.

SOLUTION: In hot rolling equipment in which the tail end 10B of the preceding material 10 and the tip 12A of the succeeding material 12 are joined together with a movable joining device 24 in running after hot rough rolling, and rolling is performed by continuously feeding it to a finishing mill, detecting devices 44, 48 for optically detecting a slab and a image pickup unit 46 with which images of both the tail end of the preceding material and the tip of the succeeding material can be picked up are provided.
