RH-OB method (RH-oxygen blowwing The)
RH-OB methodrefers to in the vacuum chamber on the sidewall of the liquid steel vacuum circulation degassing method device to install an oxygen blowing gun, blow to the vacuum chamber of the molten steel surface oxygen, removal of 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, 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, 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 world pie network information , RH, light handlingWorld Steel Pipe , light processing in the RH, a 0B vacuum chamber pressure, dissolved oxygen content in molten steel in the molten steel of carbon content.
