Abstract
Description
technical field
[0001] The invention relates to a vacuum refining device in the metallurgical manufacturing industry, in particular to an integral vacuum chamber manufacturing method in the vacuum refining device adopting a vacuum cycle degassing method (RH). Background technique
[0002] The vacuum tank or vacuum chamber is one of the important equipment in the RH vacuum refining device. When the vacuum tank chamber is processing molten steel, its interior is in a vacuum state, and molten steel circulates in it. When the vacuum chamber does not process molten steel, its interior returns to normal pressure. The internal temperature and pressure of the vacuum chamber fluctuate, the working conditions are harsh, the operating load is high, the reliability of the equipment is high, and the manufacturing quality must be strictly guaranteed.
[0003] The main body of the vacuum chamber is welded steel structure, lined with heat insulation and refractory materials. According to...
