The stretch reducing mill roller is the main tool for sizing.The machining precision of sizing roller will directly affect the assembly precision of sizing machine and the quality of seamless steel tube.The purpose of sizing is to make the steel tube into the required accurate size and roundness , and to further improve the quality of the outer surface of the steel tube.After sizing, the steel tube has smaller diameter deviation, smaller ellipticity, better straightness and smooth surface.
