Co bubble H2 and N2 partial pressure is very low, for these gases, the Hebei calcium - barium compound deoxidizer, CO bubbles are a small vacuum chamber; small particles adhere to the surface inclusions CO bubbles floating discharge. Steelmaking and other reactions are closely linked. Oxidizing the slag, the oxygen content in the steel so affected by the decarburization reaction. Causing splashes and spills. Oxygen converter, calcium silicon barium compound deoxidizer, CO exhaust gas and the pool rises unevenness caused by it is often the main reason for the generation of splash. Favor the formation of slag. Exotherm. Steelmaking slag process: adjustment operations steel, iron slag chemical production, alkalinity and viscosity and response capacity. The purpose is through the slag - metal reaction has been refining the requirements issued by the composition and temperature of the metal. For example BOF slag and blowing operation is to generate sufficient liquidity and alkalinity of slag to the sulfur, phosphorus dropped below steel cap plan, and when blowing slag splashes and overflow volume is minimized.
