Application of induction hardening and tempering equipment in metal processing

Application of induction hardening and tempering equipment in metal processing

The induction coil is fixed in the medium frequency induction hardening and tempering equipment. So only the heating temperature parameter needs to be considered when using induction hardening and tempering equipment for heat treatment process.. The internal structure has the following characteristics when hardening and tempering. 1.Phase change characteristics: Since the induction heating and tempering equipment has fast heating speed, it increases the actual phase transition point of the steel. The faster the heating is, the higher the austenite temperature will be, and the austenite grains will be very fine. Upon quenching, fine or cryptocrystalline martensite structures are obtained. http://www.foreverfurnace.com/sub-products-catalog-c 2. When the induction heating device is heated, since the workpiece is in the alternating magnetic field, the alternating magnetic field also has an influence on the phase change in the steel. Under the interaction of the magnetic field, the tissue stress and the thermal stress, the austenite structure is not increased. Instability,it can increase the substructure density in austenite, which makes the intermediate frequency quenching hardness than ordinary quenching. 3. Due to the high heating speed and short time of induction hardening and tempering equipment, the austenite grains are too late to grow and can significantly reduce the oxidation and decarburization of the workpiece. Therefore, the surface hardness and surface quality can be obtained after quenching with induction hardening and tempering equipment. This is particularly important for parts whose surfaces require high strength properties. Direct hardening after forming heating can significantly increases the economic benefits. In terms of medium-frequency induction hardening and tempering equipment, the thermal efficiency is greatly improved. http://www.foreverfurnace.com/products/quenching-and-tempering-furnace.html The heating time required for heating a piece of work by the induction hardening and tempering equipment is not comparable to the box type resistance furnace. It does not require the warm-up process and the formed semi-finished product does not need to be reprocessed. Using induction hardening and tempering equipment for heat treatment processing, electricity costs can save more than 60%. Forever is engaged in producing induction heat treatment equipment for more than 14 years, which can be used for heat treatment of round bars, grinding bars, sucker rod, torsion bar, stabilizer bar, screw bolt, tubing, pipeline and so on .Welcome to send us inquiry !
