High-speed steel roller has high hardness and wear resistance at high temperatures. The core is made of high-strength ductile iron by centrifugal method. Through the control of composition and heat treatment process, the hardness of the working layer can reach 70-90HSC, and there are vanadium, tungsten, niobium, and molybdenum composite carbides distributed on the martensite matrix. The hardness of the working layer is uniform, and the wear of the groove is uniform. This kind of roll is used in the finishing mill stand to increase the operation time of the mill and improve the surface quality of rolled products.
High-speed steel rolls are high-performance rolls that are commonly used in high-speed rolling processes. High-speed steel is a type of steel that contains a high proportion of carbon and alloying elements (such as tungsten, molybdenum, vanadium, etc.) and has extremely high hardness, which enables it to maintain shape and dimensional stability under high loads. High-speed steel can still maintain its hardness and strength at high temperatures and is suitable for use in high-temperature rolling environments. High-speed steel rolls can be used for rolling a variety of materials, including but not limited to carbon steel, stainless steel, alloy steel, non-ferrous metals, etc.
