Processing method for re-grinding of threaded roll ring

Abstract

The invention provides a processing method for re-grinding of a threaded roll ring. The processing method comprises the following steps of (1) grinding a fatigue layer of the threaded roll ring; (2) milling: correctly finding a milled first transverse rib of an upper roll in the previous re-grinding processing cycle, and milling; aligning and adjusting any transverse rib in a lower roll, positioning, aligning teeth and milling. The processing method has the advantages that the grinding amount of the re-grinding of the threaded roll ring is reduced from 2.5-3mm to 1-2mm in each cycle, the group difference of the roll ring is reduced, the difficulty in roll matching is decreased, the consumption of rolls is decreased, the number of use cycles of the roll ring is increased, the service life of the roll ring is prolonged, the processing cost is reduced, and the labor intensity of workers is decreased.

Description

technical field [0001] The invention relates to the technical field of iron and steel production, in particular to a processing method for regrinding a threaded roller ring. Background technique [0002] For a long time, secondary processing has to be carried out after the roll ring of the high wire coil is off-line. The secondary processing of the roll ring is carried out on the basis of grinding all the defects on the surface of the roll ring and the transverse ribs in the roll groove. The new transverse rib processing, so that the average grinding amount per cycle is more than 2.5mm, resulting in a large amount of roll ring grinding, large group differences, and difficult roll matching. At the same time, due to the large amount of grinding each cycle, the consumption of roll rings Also big. Contents of the invention [0003] In order to solve the above-mentioned technical problems, the present invention provides a threaded roller ring back grinding processing method, t...
