Explanation
off furnace refining technology of blowing oxygen decarburization into liquid steel under vacuum condition. It is mainly used to produce high chromium stainless steel, ultra-low-carhon steel and special steel for vacuum refining and vacuum degassing treatment. Due to the strong carbon deoxidation capacity under vacuum conditions, the carbon content in steel can be reduced to a very low level, thus ensuring a high yield of chromium. Determine the blowing endpoint by measuring the vacuum degree and analyzing the composition of the exhaust gas.
