Abstract
PURPOSE: To reduce the percentage of defective rolled product of ring type provided with the necessary residual removable maring, by detecting the value of volume of the material being rolled, before starting or while executing the rolling work, and by distributing the removable maring depending on the detected value accorrding to the previously set reference.
CONSTITUTION: The outer diameter, inner diameter and breadth are measured by the size measuring means installed in the Wagner mill, etc; these values, being measured just before the end of rolling work, are read into the rolling control unit, which then correct the initially set aim values. In the meantime, the temperature of the rolled material is measured and is read into the rolling control unit. Depending on these data, the amount of shrinkage is forecast by calculation, and the temperature is corrected so as to make the size of the product of rolling work after being cooled to be the required size. Depending on this, the final rolling is executed, and the pressure is released at the point where the product size becomes the changed aim size. As a result, the rolled product provided with the residual removable margin being distributed according to the reference can be obtained. According to this method, the turning work for the ring type product after the rolling work becomes easy, and the yield of the product is improved.
