Features

▪ The material is made of No. 45 seamless steel roll or alloy steel through welding, stress relief, tem-pering, quenching and other mechanical processing.

▪ The flow channel inside the roller is reasonable, and the temperature difference of the roller surface is ±1 degree Celsius.

▪ The outer tube of the roller is subjected to intermediate frequency quenching and normalizing treat-menấThd the surface hardness of the roller body reaches 55HRC

▪ The thickness of the chroming layer is made according to the customer's needs. Generally, the thick-ness of the electroplating layer is 100u, and the hardness reaches 60HRC after hard chrome plating.The roughness of the mirror roller reaches Ra 0.01, and the concentricity is less than 0.01mm.
