The tempered medium carbon steel pipe is used instead of the surface induction hardening process to en-hance the consistency of hardness and hardness of the contact roll surface to improve the wear resistance of the con-tact roll;In order to avoid welding defects of medium carbon steel and improve production efficiency,interference fit between shaft head and roll surface is used to check the selection of interference quantity.
