VD vacuum refining furnace is a commonly used refining process equipment, mainly used for deoxidation, impurity removal and other operations of molten steel, so as to obtain high purity, low impurity content of high quality steel.
VD refining furnace is a vacuum degassing device, which is mainly used to remove H and N harmful gases in steel, reduce H in molten steel to ≤ 2ppm, and reduce the generation of white dot scraps in steel.
At the same time, partial deoxidation and s removal, fine adjustment of composition and modification of inclusions are also available. The purity of the molten steel treated by the VD refining furnace is further improved.
Equipment Application:
VD refining furnaces are widely used in the field of iron and steel metallurgy, especially play an important role in the production of high quality and special steel.
It is applicable to the production of high speed steel, alloy structural steel, tool steel, heat resistant steel, corrosion resistant steel, etc. In the steel industry, VD furnace has become an indispensable key equipment.
In a word, VD refining furnace is an important refining process equipment. Through vacuum operation and addition of refining agent, oxygen, gas and impurities in molten steel can be effectively removed to obtain high purity and low impurity high-quality steel.
