Abstract
PURPOSE: To accurately perform the forecast-control of the roll gap of the edging roll of the rolling mill, by actually measuring the temperature of both edges of the rolled material on the feed-in side, and by arithmetically forecasting the dog bone recovery rate and the spread factor.
CONSTITUTION: The temperature of the rolled material P at the points of a specified distance from the side edges are measured by the thermometers 31 installed on the run-out side of the first stand. The thickness and breadth on the run-out side of the first stand are arithmetically operated, and these velues are inputted to the computer 4 which then computes the spread obtained by the rolling work of the horizontal roll of the second stand. Meanwhile, the computer 5 computes the dog bone recovery rate by the rolling work of the horizontal roll of the second stand. These two values are inputted to the computer 6 which then computes the roll gap of the edging roll of the second stand. This value of the roll gap is set in the edging roll gap control unit 8. This operation is repeated with a specified period or for every specified length of the rolled material P.
