The mechanical vacuum degassing furnace system consists of 16 first-stage oil rotary pumps, 8 second-stage Roots pumps, and 20 third-stage Roots pumps.
READ MOREIn order to homogenize the composition and temperature, the gas stirring process in the ladle appeared. The most striking is the adoption of secondary refining, which greatly improves the output and quality of steel. However, what is the main task and purpose of secondary refining? The composition of molten steel, decarburization, deslagging and refining of molten steel shall be adjusted according to the target of molten steel, molten steel melting, deslagging and refining.
READ MOREDevelopment of secondary refining technologyThe secondary refining has the functions of making the temperature and composition of the molten steel uniform, adjusting the composition of the molten steel, degassing (decarburization, denitrification, dehydrogenation), deoxidation, desulfurization, deph
READ MORERefining to remove oxidesAt the end of the secondary refining, in order to obtain high purity molten steel, so-called "bubble floating purification" is required. Here, "bubble floating and purification" means the boiling of molten steel caused by small bubbles near the bottom of the ladle top slag r
READ MOREThe application of post-combustion technology in steelmaking is embodied in the use of converter oxygen lances (converter post-combustion oxygen lances) and RH top-blowing lances (represented by RH-KTB), as well as in electric arc furnace steelmaking (two On the secondary combustion PC gun), it show
