Metal forging, which is needed for every metal workpiece, is used in metal forming processing. After forging, the metal workpiece can meet the user’s requirements, such as shape and size, and so on, in order to put it into production. stainless steel forging heat treatment furnace The following is the whole process of forging.
1.Hot forging: a forging process above the recrystallization temperature of a metal is called hot forging. Cold deformation strengthening and recrystallization exist in the process of deformation and belong to dynamic recrystallization.
2. Cold forging: the forging process carried out at room temperature is called cold forging. Cold forging can avoid the defects of metal heating, obtain high precision and surface quality, and improve the strength and hardness of the workpiece. However, the deformation resistance of cold forging is large, the equipment of large tonnage should be used, and recrystallization annealing and other auxiliary processes should be added when deformation is repeated. At present, cold forging is mainly limited to the processing of low carbon steel, non-ferrous metals and their alloys.
3. Warm forging: a forging process carried out above room temperature and below recrystallization temperature is called warm forging. Compared with hot forging, the billet has less oxidative decarbonization, which is beneficial to improve the precision and surface quality of the workpiece, and compared with cold forging, the deformation resistance decreases and the plasticity increases, so the pre-annealing, surface treatment and inter-process annealing are generally not required. Warm forging is suitable for high-carbon steel, medium-high alloy steel, bearing steel, stainless steel, etc.
4. Isothermal forging: in the whole process of forging, the forging method in which the temperature remains constant is called isothermal forging.
On the forging process of metal workpieces, if you have any other questions, please call to consult the remote electric machinery, the manufacturer is a domestic professional metal heat treatment furnace equipment manufacturers, engaged in induction heating and heat treatment for more than 10 years, welcome to call to consult, Look forward to your call.
