Every step of metal heat treatment is very important, and the timing of each step can reach the appropriate temperature. If there are stresses before the heat treatment, they may cause problems of forming and warping. After processing, please use sufficient stress relief measures. By carefully controlling the temperature, the influence of overheating and combustion in metal heat treatment can be reversed. The correct temperature is required to ensure that uneven heating does not occur.
Other ways to correct overheating include checking tools to ensure that the correct anti decarburization solution and metal are used for protection to ensure even heating. If the metal is heated unevenly, usually because there is no preheating, the remedy is to allow the metal to cool slowly before reheating and hardening. Selective tempering: the design of components may require selective softening and hardening.
The highly restricted thermal mode achieved by induction heating is particularly useful in this case and can also provide significant economics throughout the processing sequence. The hardness patterns of induction tempered steel bars and tubes of various sizes have been interpreted according to effective tempering parameters, which allow continuous heating and cooling cycles to be converted into equivalent fixed temperature treatments. In this way, the influence of induction heating variables on the tempering behavior of many hardened carbon steel and alloy steel has been studied. Unique air flow system for quick heating - short cycle hot air impact design, up to 4500 kg / h (10000 lb / h) capacity, unique water, polymer, immersion, mixed spray quenching and precision air quenching design, including fast transmission system, no pits or special foundation.
Metallic materials consist of the microstructure of small crystals called "grains" or microcrystals. The properties of particles (i.e. particle size and composition) are one of the effective factors to determine the overall mechanical properties of metals. Heat treatment provides an effective way to control the properties of metals by controlling the diffusion rate and cooling rate in microstructure. Changzhou heat treatment is usually used to change the mechanical properties of metal alloys, control hardness, strength, toughness, ductility and elasticity.
Because of how this material is formed and sintered, compared with forged alloy, powder metal has some limitations in its application. These limits may include overall strength and impact resistance. When the powder metal parts are processed by induction heat treatment, the strength, durability and hardness are increased and improved in key areas. The result is part of better handling of continuous applications! Most steels are tempered in the temperature range 500 to 600 ° F. You need to find a mechanical manual or one of the forging references, such as edges with tempering data. If you plan to stay in the tool business, you should purchase a (relatively expensive) reference.
