The machining accuracy of pipe sizing and reducing rolls directly affects the assembly accuracy of sizing mill stands and the quality of seamless steel tubes.
Our sizing rolls are made of chilled nodular cast iron. The production process includes raw material testing, medium-frequency induction melting, centrifugal composite casting, rough turning, heat treatment, CNC finishing, inspection and final packaging.
Supported by full-process quality control, our rolls feature high strength, high precision, excellent wear resistance and long service life.
