Introduction of Converter Steelmaking

From the torpedo car shipped after hot metal desulphurization and slag treatment in converter as the main burden, 10% below the scrap. To burning in oxygen blowing of converter, then the excess carbon oxidized iron water and release a lot of heat, when the probe measured reaches a predetermined low carbon content, namely stop oxygen And out of the steel. Generally need a deoxidization and adjust the ingredients in the ladle operation; Then carbonized rice husk to prevent the molten steel in molten steel surface by oxidation, can be sent to continuous casting or die caster area.

Of high steel grade can increase the bottom blowing argon, RH vacuum treatment, powder spray (SI - CA powder and degeneration of lime) can effectively reduce the gases and inclusions in the steel, and have further to fall the action of carbon and sulfur. In these measures after refining outside the furnace can eventually fine ingredients, meet the needs of high quality steel.
