Abstract

PURPOSE: To control the sheet breadth on the run-out side of the horizontal roll, by detecting the shape and size of the dog-bone of the material to be rolled at the middle point between the vertical roll and the horizontal roll.
CONSTITUTION: The blank material 10 fed in the arrowed direction is rolled by the vertical roll 20; the shape DB of the dog-bone and the sheet breadth WA of this material 10 on the run-out side of the vertical roll 20 are measured by the dog-bone shape measuring device 26 and the sheet breadth measuring device 28. The sheet breadth operator 30 operates the forecast for sheet breadth WP on the run-out side of the horizontal roll 22 from thus measured dog-bone shape DB, the sheet breadth WA, and also the data previously inputted from the draft schedule of the horizontal roll 22, such as the feed-in side sheet thickness H0, the run-out side sheet thickness H1, the radius R of the horizontal roll 22, etc.; thereupon the difference between thus forecast run-out side sheet breadth WP and the objective run-out side sheet breadth, is inputted to the roll gap controller 36 of the vertical roll 20. The roll gap controller 36 adjusts the roll gap of the vertical roll 20 by the vertical roll gap adjusting motor 34 so as to match the sheet breadth on the run-out side of the horizontal roll 22 to the prescribed sheet breadth.
