The Kocks Rotation Mill -KRM-is an innovative elongation method for seamless tube production up to 4.5" diameter at production levels up to150,000 TPY. Using the principle of cross roll elongation, the machine rotates four rolls around the workpiece. A retained mandrel sets the wall thickness to a precision that exceeds existing industry norms. The KRM process performance has been truly excellent. Attributes include high billet weights, elongation of up to 9.5 in one pass, and eccentricity atdoi:10.5151/1983-4764-26563 fatcat:ncv6wf2gh5hlngl4akcc7g3sla
