Abstract

PURPOSE:To adjust the roll gap, and to control the product size to high accuracy, by installing two rod diameter measuring devices and the comparison arithmetic unit, in case of rolling of the rod, etc., by the common drive type block mill. CONSTITUTION:The size meters 13, 14, for the thickness (h) and the breadth (b) of the material 30 to be rolled, are arranged in the rear of ten units of continuous mills, driven in common by the motor 11 and the gear 12, (in which ten couples of vertical rolls 1, 3 ... and horizontal rolls 2, 4 ... are alternately arranged in the advancing direction of the material 30 to be rolled); the output signals of individual size meters 13, 14, are inputted to the arithmetic units 15, 16, which operate the amount of control through comparison for these inputs with the output signals from the aim thickness setter and the aim breadth size setter 15', 16'; and the output of arithmetic units 15, 16, are inputted to the screws 17, 18, and the gaps of rolls 1 and 10 are controlled and adjusted. The rolling reduction of intermediate stands from 2 to 8 do not give any influence to the breadth size; and it is experimentally confirmed that the control of the rolling reduction in the stand 1 is the most effective. Accordingly, the product with high accurate size can be manufactured.
