Product Introduction
Forged steel rolls
Semi-high-speed steel rolls
When the chromium content is 3% or higher, it has better toughness and wear resistance, and a deeper hardened layer can be obtained, which can meet the requirements of high-speed rolling and high-load rolling. Semi-high-speed steel rolls are a type of roll material that combines the characteristics of high-speed steel and common tool steel. They are mainly used in the steel rolling process, especially widely applied in cold rolling or medium to high-load hot rolling scenarios
High-speed steel rolls
By adding elements such as tungsten, molybdenum and vanadium, the hardness can reach 90-95HSD, and the service life is 2-3 times that of traditional Cr5 rollers. It features high hardness, high wear resistance and good thermal stability. High-speed steel contains a large amount of alloying elements such as tungsten, molybdenum, chromium and vanadium, forming complex carbides, which enables it to maintain high hardness and strength at high temperatures and withstand higher rolling speeds and rolling forces.
Scope of application: Mainly used for rolling high-precision and high-performance cold-rolled products (such as high-strength automotive steel), such as ultra-thin strip steel, precision alloy strip steel, etc. It is particularly suitable for high-speed rolling and the rolling of materials that are difficult to deform.
Low-carbon alloy steel rolls
Such as 40Cr, 20CrMnTi, 35CrMoV, etc. Low-carbon alloy steel rolls are used for rolling softer materials, such as low-carbon steel and aluminum foil
