Description	Adopting bimetallic composite extrusion casting process, the stmucture is dense, with high red hardness, wear resistance.impact resistance, and processability, It is not easy to produce pockmarks, peeling. or slotting during use; It can reduceintermediate rolling waste caused by rapid wear of the rolling groove, therebyimproving the yield of the product, Reducethe number ofroll and groove changes to improve the operation rate of the roling mill:; Good wear resistance, able toeffectively control negative deviation rolling.

Product Description
 

It is used in the roughing stands of round and sections, especially the BD2 mills for rail & beams.

Compared with other nodular iron rolls, NCC rolls have unique material and heat treatment process ensuring they are good enough to replace the traditional cast steel rolls but with a better life.

We control the carbide at a very low level (less than 5%) by reducing the chrome down to 0.3%, raising the silicon and applying isothermal quenching to make the carbide solid solution into the matrix.

Meanwhile, we can achieve a matrix of tempered sorbite/bainite by applying heat treatment d increasing nickel. This type of matrix has much better performance than the pearlite on the resistance of wear, fire crack and impact, especially the excellent red hardness thanks to the molybdenum.

Qingdao XinShengYuan Roller Co.,Ltd is located in the haibin industry development zone in Qingdao. next to the Port of QingDao and expressway, conventient transportation.
