Nodular Iron Rolls

        The outer roller body is made of ductile iron. The metallographic structure of ductile iron is composed of spherical graphite, cementite and metal matrix. Due to the uniform distribution of graphite spheroids, the properties of matrix structure are fully displayed. Nodular iron rolls have high strength, good thermal crack resistance and wear resistance, and can withstand large rolling load, which is excellent. The above good properties depend on the characteristics of its structure, which is mainly affected by chemical composition, cooling rate, spheroidization and heat treatment. Reasonable selection of chemical composition, ensuring the effect of spheroidization and incubation, and strict control of casting process and heat treatment system are the keys to ensure the good performance of nodular cast iron rolls. WEILANG adhere to the attitude of excellence and exquisite technology to produce a variety of excellent rolls.Products are exported to the world, through the proportion of adjustment to meet your requirements.
