Natural gas tempering furnaceThe furnace is mainly used for the composite heat treatment process of quenching and tempering steel or steel parts. After quenching and tempering, medium carbon quenched and tempered steel can be obtained. The quenching and tempering furnace has good comprehensive mechanical properties, that is, it has good plasticity and toughness while maintaining high strength. A large number of structural parts on various machines are made of quenched and tempered steel.

Quenching and tempering is a comprehensive heat treatment process that combines quenching and high-temperature tempering. Most quenched and tempered parts work under relatively large loads, bearing the effects of tension, compression, bending, torsion, or shear. Some surfaces also have friction, requiring certain wear resistance, and so on. The performance requirements for quenched and tempered parts in mechanical products vary depending on their stress conditions. Generally speaking, various quenched and tempered parts should have excellent comprehensive mechanical properties, that is, a suitable combination of high strength and high toughness, and the parts should work smoothly for a long time.

1. In terms of strength, quenched and tempered parts should have high tensile strength and fatigue strength to prevent excessive plastic deformation or fracture during operation due to external loading.

2. In terms of toughness, it should have high impact toughness, a certain degree of plasticity, and minimal brittle failure. Parts should have high stress redistribution ability during plastic deformation to prevent damage caused by impact vibration or stress concentration. For quenched and tempered parts under certain working conditions, they also need to have high wear resistance and corrosion resistance, which requires further chemical heat treatment or surface heat treatment.
