Wuhan handern machinery high temperature deformation heat treatment
High-temperature deformation heat treatment is a process of heating steel to a stable austenite region for a period of time, deforming in this state, and then performing fire to obtain a martensite structure. www.handern.com Meltblown non-woven equipment
After high temperature deformation heat treatment, the shaft can be tempered properly to improve the R of steel. And 0, improve the plasticity and cuttability of steel. Moreover, other indicators such as crack propagation work, impact fatigue resistance, fracture shear fatigue fracture resistance, delayed fracture crack propagation resistance, local surface damage resistance and contact fatigue resistance under high contact stress have been improved, in addition, high temperature deformation quenching can also be reduced Steel brittle transition temperature and notch sensitivity. www.handern.com Meltblown non-woven equipment
The high-temperature deformation hardening effect is not as good as the low-temperature deformation quenching, but there are no special requirements for the material. One-carbon steel and low-alloy steel are suitable for easy installation in the rolling forging production process, so they have developed rapidly in recent years. www.handern.com Meltblown non-woven equipment
The high-temperature deformation heat treatment process mainly includes: high-temperature deformation quenching, high-temperature deformation normalization, high-temperature deformation isothermal quenching, sub-temperature deformation melting, heat treatment using deformation to strengthen genetics, surface high-temperature deformation refractory heat, and composite deformation heat treatment. www.handern.com Meltblown non-woven equipment
Among them, the high-temperature deformation quenching is mainly used for processing carbon steel and alloy structural steel parts such as connecting rods, crankshafts, blades, springs, agricultural machinery and gun parts, etc. The high-temperature deformation normalization is suitable for improving the plasticity of the element V, Nb of the melt-blown non-woven equipment equipment, and the preliminary heat treatment of carbon steel and alloy structural steel forgings with trace element www.handern.com. The surface is deformed at high temperature and can be used for high-speed transmission shafts, bearing rings and other cylindrical or ring parts, track shoes and machine shovel and other wearing parts. Compound deformation heat treatment is suitable for Mnl3, Gongqi steel and cold work die steel and other difficult-to-strengthen steel to improve its comprehensive mechanical properties. www.handern.com Meltblown non-woven equipment
