RH-OB method (RH-oxygen blowwing The)
refers to an oxygen blowing gun installed on the sidewall of the vacuum chamber of the device of the liquid steel vacuum circulation degassing method, the steel surface to the vacuum chamber of the oxygen blowing, off In addition to the carbon in the molten steel. This method can reach a level of 10-4% after the carbon in the molten steel in RH, the production of low carbon and ultra-low carbon steel World Pipe network informed, in particular, is an important means of very low carbon steel. The oxygen lance is used in the argon-cooled double nozzle. RH light processing, the RH-OB light processing need to keep blowing oxygen to the molten steel, so that the molten steel continuous decarburization World Pipe network informed, the carbon content of molten steel to achieve a very low level. The figure given in the molten steel aluminum deoxidation processing, after RH RH vacuum deep decarburization processing of Alcan, RH, light handling, light processing in the RH, a 0B vacuum chamber pressure, dissolved oxygen content in molten steel in the molten steel of carbon content.
