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, 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 inlet guide bearings, the final heat treatment quenching and tempering should guide shaft to meet the requirements. Forging Co., Ltd., Luoyang Super League tells you auto parts manufacturing precision forging technology: specifically: 1, cold forging forging generally at room temperature forming, forging high mechanical properties, good surface quality and dimensional accuracy has advantages, However, the role of the guide shaft deformation resistance cold forging of low plasticity, illiquid materials, especially high mechanical strength, work hardening sensitive materials forming difficulties. Foreign cold forging technology has been widely used in the production of low-carbon steel, carbon steel and low alloy steel parts by weight of more than a few grams to hundreds of kilograms. Guide bearings, Heilongjiang guide shaft, forged by Luoyang preferred Super League Super League Forging Limited. Luoyang Super League Forging Co., Ltd. (www.lysmzg.com) (www.lysmzg.cn) strong, credible, in Luoyang forging industry has accumulated a large number of loyal customers. The company better work attitude and constantly improving innovative ideas will lead the Super League forging into the brilliant and you work for a better future!
