Luoyang Super League Forging Co., tells you the purpose of forging process: There are two, one will be forged ingot economically rough shape desired, namely molding; the second is to improve the metal tissue damage by forging ingot cast microstructure, the tissue homogenization, grain refinement car guide bearings, making holes, loose, shrinkage defects such as welding. Typically, large ingots by smelting workshop forging direct heat to the workshop. For the defective weld inlet guide bearings, large forgings forging generally guided a lot of pressure exerted on the shaft of the hydraulic press, mainly free forging process. Heat due to the size effect, heat treatment of large forgings has its own characteristics, we must fully consider the metallurgical properties of large forgings, transient stress and residual stress of large forgings produced during the heat treatment, the phase change affects the latent heat of the heating and cooling process, return Fire brittle and thinning tissue. Forging Co., Ltd., Luoyang Super League tells you heat large forgings are mainly two: the first heat and second heat. The second heat treatment, the ultimate performance of the heat treatment of the guide shaft, and its main purpose is to make large forgings roughing after the organization needed to get the best, in order to ensure good overall performance of large forgings. The second heat treatment process are commonly used quenching, normalizing plus tempering, normalizing plus aging and so on. Requirements for high hardness of forgings, such as a large cold roll, the final heat treatment quenching and tempering should be used to meet the requirements.
