The Usage of 156 mm Diameter Continuous Cast Billets on “140” Pipe-rolling Plant for Pipe Production

Abstract

The research on the possibility of unification of piercing and reeling mills rolls for screw rolling for both decreasing and increasing the diameter of crude pipes was conducted. In the result the possibility was confirmed. The technology of wide range of sizes “140” pipe-rolling plant 156mm diameter continuous casting pipe production was developed to use one roll design on piercing mill and one roll design on reeling mill instead of two roll designs for each therefore decreasing the amount of sizing mills grooves.
