Abstract
PURPOSE: To improve the accuracy in presumption of rolling load in the course of the rolling of thick steel plate, by presuming average temperature of material to be rolled from actual rolling load of the breadthside rolling pass, and then, presuming temperature and rolling load of other rolling passes based on the result.
CONSTITUTION: A breadthside rolling is performed on a steel material 2 coming out from a heating furnace 1 with a rolling mill composed of work rolls 3 and backup rolls 4. During the course of this breadthside rolling, a rolling load P detected by a load detector 6 is inputted into a process computer 5. The computer 5 operates a temperature at the time of completion of the breadthside rolling from rolling load P at each pass of the breadthside rolling, and obtains an average value of completion temperatures at each pass, and then, uses those values for calculating presumed rolling temperatures and rolling loads. Above- mentioned processings are performed by the computer 5, and, from the result, a set value for the rolling reduction is operated. Then, preparations for rollings in the downstream starting from a thickness reducing rolling process are made by driving a motor M of the rolling equipment.
