Forging Co., Ltd., Luoyang Super League for you about forging defect classification methods: Classification by step process of forging defects or defects which arise from the process according to distinguish between low-speed ring, can be divided into: defective raw material production process produces low-speed internal gear Circle parameters, defects and heat generated during the process of forging defects generated. Forging process according to the order of each step of the forging process can also be generated in the low-speed ring stent defects, broken down into the following categories: a defect generated by the material; defects generated by heating: by forging defects generated by: cooling produced defects and defects produced by the cleaning and the like. Different processes can produce different forms of defects, however, defects of the same form may also come from different processes. Because the cause of forging defects often associated with raw materials and forging heat treatment process, and therefore when analyzing the causes of defects generated in the low-speed forging ring processing, not in isolation for. Forging Co., Ltd., Luoyang Super League for you about the performance of metal forging metal material weldability refers to the ability to adapt to the welding process: because welding is a non-uniform heating process, so good thermal conductivity, shrinkage small metal material weldability are better. Welding performance, the metal after welding to ensure the same shape and size, do not produce the weld, and welded joint having sufficient strength. The low-speed ring forgings, low-speed internal gear, forging workmanship Super League Super League from Luoyang Forging Limited. Luoyang Super League Forging Co., Ltd.
