VOD type vacuum refining equipment is one of the most widely used out-of-furnace refining equipment in the world. It has many advantages such as simple equipment, low investment, low cost, many types of refined steel, high quality and convenient operation, so it has become an essential refining method for special steel plants.Vacuum heat treatment of sheet parts VOD ladle refining furnace has many functions such as vacuum degassing, oxygen blowing decarburization, vacuum feeding, argon blowing stirring, non-vacuum temperature measurement and sampling, wire feeding and so on. It can refine bearing steel, alloy structural steel, spring steel, high-quality carbon steel and ultra-low carbon stainless steel. Vacuum Brazing and Heat Treatment Process of Stainless Steel Surgical Instruments Because of its strong vacuum degassing ability, it can ensure that the content of hydrogen, oxygen, nitrogen and carbon in the steel reaches the lowest level, and accurately adjust the composition of molten steel, so that the inclusions can be fully floated, and the cleanliness of the steel can be effectively improved. Because it refines many types of steel and high quality, it can more flexibly adapt to the needs of market competition for users, and can refine the steel types required by the market in time, thereby increasing the economic benefits of the enterprise.How to control distortion in vacuum heat treatment of sheet parts?
