Abstract

PURPOSE:To control the gap between the bottoms of roll grooves of a sizing machine according to a factor obtained below, and to improve the accuracy of outer diameter of a pipe, by measuring the gap between the bottoms of roll grooves of final two stands and the outer diameter of a pipe during the rolling work continues, and by obtaining an influence factor of the gap between the bottoms of roll grooves against the pipe's outer diameter. CONSTITUTION:During a rolling work continues, the gap B1 between groove bottoms of a rolling roll 7 of a final stand of a sizing machine, the pipe's outer diameter D1 in the direction B1, and the gap B2 between groove bottoms of a rolling roll 8 of a stand on this side of the final stand and the pipe's outer diameter D2 are measured. The influence factors a1, b1, c1, a2, b2, c2 of gaps B1, B2 between groove bottoms against the pipes outer diameters D1, D2 are included in an equation I; these factors are operated for every rolling process and are taken as a control index for controlling the pipe's outer diameter.
