[0002] The vacuum refining furnace has multiple functions such as vacuum degassing, argon blowing stirring, oxygen blowing decarburization, etc. It can refine bearing steel, alloy structural steel, spring steel, high-quality carbon steel, ultra-low carbon stainless steel, etc. Due to its extremely strong vacuum degassing ability, it can ensure that the hydrogen, oxygen and nitrogen content of the steel reaches the lowest level, and accurately adjust the composition of molten steel to make inclusions fully float, thereby effectively improving the purity of the steel.

[0003] The vacuum pump group of the vacuum refining furnace is the key process equipment of the refining furnace. At present, most vacuum pumps use steam jet pumps, in which the nozzle of the steam jet pump is fixed on the jet pump housing. The position and shape of the nozzle in the jet pump are fixed. This jet pump with a fixed nozzle position can only operate under the designed working conditions, and has poor adaptability to changing working conditions. When the actual working conditions vary from the design values, its working performance will deteriorate greatly, causing the entire system to be unable to operate stably. Utility Model Content
