Technological Development of RH Furnace and Influence on Refractories
Steel furnace external refining, also known as secondary metallurgy, is one of the main development directions of steel metallurgy technology. The purpose of external furnace refining is to remove the inclusions and impurities in the steel water. deaerate. Adjust the chemical composition of water steel and alloy homogenization, measures include blowing inert gas mixing. vacuum degassing. decarbonization. deoxidize. Feed the silk. Powder spraying and alloying, etc.
In recent years, with the rapid development of the metallurgical industry, the requirements for steel quality are getting higher and higher, and the demand for pure steel is increasing, thus promoting the rapid development of RH refining technology. So far, RH refining technology has been transformed from the original single degassing purification to include vacuum decarburization. Oxygen decarbonization. Powder desulfurization. Temperature compensation. Multifunctional out-of-furnace refining technology for uniform temperature and composition.
The increase of RH vacuum cycle degassing furnace top gun mode, the expansion of function is below the middle groove. The lower groove wall and groove bottom working lining refractory material is a test.
