Steel bar hardening and tempering equipment is mainly used for heat treatment of steel bars. By controlling process parameters such as heating, cooling, and insulation, the steel bars can obtain the required mechanical properties and microstructure. The specific equipment principle is as follows:
1. Heating: Place the steel bar in a heating furnace and heat it to the desired hardening or tempering temperature through methods such as resistance heating or induction heating. During the heating process, it is necessary to control the heating rate and temperature uniformity to avoid deformation or cracks caused by excessive temperature gradients.
2. Cooling: After heating to the required temperature, the steel rod needs to be rapidly cooled to transform its structure into martensite. The cooling method can be water cooling, oil cooling, or air cooling, depending on the steel type and requirements. The cooling process requires controlling the cooling rate to ensure that the steel bar achieves the required hardness and microstructure.
3. Insulation: After hardening, the hardness of the steel rod may be too high and needs to be hardened and tempered. Usually, steel bars are placed in a constant temperature furnace and kept at a certain temperature for a period of time to achieve structural stability and hardness adjustment. steel bar induction heat treatment machine
