Abstract
PURPOSE: To suppress width deviations and reduce the discarding quantity at the side edge parts by estimating and operating the thickness distributions in the plate lengthwise direction at the completion of broadside pre-rolling based on the estimated values of the deformations of broadside rolling rolls and adjusting the screw- down position of the broadside pre-rolling process so as to realize these results.
CONSTITUTION: Upon starting of rolling, gauge meter thicknesses are subsequently obtained with an operator 6 based on the output information relating to the screw- down position of a screw-down position detector 4 and the output information relating to the rolling load of a load cell 3. At the same time, the informatin on plate lengths is inputted to the operator 6 by a distance meter 2. The operator 6 selects and compares the information of the target thickness of the portion now under rolling and outputs the rolling reduction change information to a hydraulic screw- down mechanism 5 so that the meter thickness of this time is made equal to the target thickness. This controlling is continued until the slab gets through the roughing mill. 1.
