Abstract
PURPOSE: To execute the rolling work for obtaining the sizing blank to be finished into the seamless tube with constant outer diameter and wall thickness being set as the aim values, by comparing the measured wall thickness of the reeling blank obtained from the elongation pass with the aim value in order to obtain the deviation value, and by adjusting the amount of expansion in the outer diameter correspondingly to above deviation data.
CONSTITUTION: At the reeling pass, amounts of expansion in outer diameter and the reduction of wall thickness are adjusted correspondingly to the variation in the wall thickness of the reeling blank (b) as follows; if the wall thickness of the reeling blank (b) is thicker than the aim value, the reduction of wall thickness is adjusted to be smaller than the specified value, and the expansion in the outer diameter is adjusted to be smaller than the specified value; and if the measured wall thickness is thinner than the aim value, the reduction of wall thickness at the reeler 4 is increased than the specified value, and the expansion in the outer diameter is increased than the specified value; these adjustments are carried out by controlling the size of roll gap of the reeler 4. Hereby, the aim value for outer diameter of the sizing blank C after the rolling pass by the reeler 4 is changed correspondingly to the size of wall thickness of the reeling blank on the exit side of the plug mill 3, and the wall thickness on the exit side of the sizer 5, that is, the wall thickness of the product, can be uniformized and the outer diameter can be made constant.
