Abstract

PURPOSE To solve the influence of the eccentricity of the roll, and to make manufacturable the product of high accuracy, in automatic sheet gauge control for the rolling mill, by employing special sheet gauge controller consisting of the arithmetic unit, etc., for the physical quantity equivalent to the eccentricity of the roll. CONSTITUTION:The computer 100 reads out various constants required for the rolling work and the control program (stated separately) of the input-output device 101 of the computer 100, and stores them in the memory 103. When the material 1 to be rolled arrives at the first stand, the output of the sheet gauge detector 2 is taken in, the output of the speed detector 61 is taken in, and the output of the load detector 41 is taken in; and then, the difference between the reference load data for the case that the roll has no eccentricity, and the load data for the case that the roll has an eccentricity, is operated as the physical quantity; the result is converted to the amount to be controlled, and is inputted to the screw 31 through the output device 104, for adjusting the gap of the rolls 11, 11'; hereby, the sheet gauge is controlled to the aim sheet gauge. The second stand 2 is also controlled by the similar system to above, and the product of high accuracy can be manufactured.
