Mill Rolls

Kennametal manufactures mill rolls from cemented tungsten carbide grades tailored for the demanding environment of hot rolling mills that produce wire rod and seamless tube.

We deliver mill rolls as unfinished blanks, semi-finished rolls with ground inner diameter and thickness, or rolls fully finished to your drawing. These mill rolls are manufactured in dimensions of up to Ø630mm outside diameter and a maximum thickness of 400mm.

Composite Rolls With Easy-To-Use Clamping System

Kennametal composite mill roll assemblies are designed for use in the high torque, low speed (<10m/sec), intermediate stands of wire rod mills where traditional cast iron or PM steel rolls are used. These roll assemblies are supplied in two axial clamping systems — a traditional hydraulic clamp, and our new mechanical clamp that's easy to install and maintain. Our mechanical clamp provides clamping forces equivalent to hydraulically clamped assemblies, but without the need for specialized tools or fluid.
