HS Die Steel & Shaped Forgings Products that applied in Metallurgical Machinery


Metallurgical machinery refers to various machinery and equipment used in the smelting, ingot casting, rolling, handling and packaging processes of the metallurgical industry. Due to the complex process of the metallurgical industry, metallurgical machinery has huge structure, large energy consumption and continuous production equipment, and most of the metallurgical equipment works in high temperature, dusty, and corrosive environments. In order to ensure the output of the metallurgical industry and reduce the loss of machinery, Metallurgical equipment must be reliable, durable and efficient.


Rolls in metallurgical machinery are in direct or indirect contact with the rolled piece during the rolling process, forcing the rolled piece to produce plastic deformation, and therefore bear great rolling pressure, rolling torque, static load and dynamic load. With the surface subjected to violent friction and wear of the rolled material, it is often overheated locally, which may cause thermal cracks. Therefore, there are strict requirements on the strength, stiffness, toughness, surface hardness, wear resistance and roll shape to ensure the quality and output of the rolled product.


The work roll requires the surface with high and uniform hardness, deep enough hardened layer, as well as good wear resistance and thermal crack resistance. Hongsheng has the production capacity to provide rough machining blanks of electroslag steel with diameters below Φ650mm.
