How are heat treatment experts made?

With different workpieces, different equipment and different process parameters, the internal structure and quality of metal after heat treatment are different one after another. Even if the materials, equipment and process parameters are the same, the structure and quality after heat treatment will be different due to different upper and lower limits of chemical composition content, heat treatment temperature and holding time.

Metal heat treatment equipment in work taboo workpiece burning and cracking defects, these two defects are irreparable defects, although can make up, but significantly increased the workload and production costs. When the steel with coarse martensite, bainite and widmanstatten structure is re austenitized, the austenite grain is still coarse when it is slowly heated to the conventional quenching temperature or even lower. This phenomenon is called microstructure heredity. To eliminate the heredity of coarse structure, annealing or multiple high temperature tempering can be used. The steel tube annealing furnace produced by jinruier Electric Furnace Co., Ltd. can provide professional steel tube annealing treatment, including steel tube bright annealing furnace, steel tube continuous annealing furnace, etc!
