Deoxidation method of molten steel excellent in deoxidation efficiency

摘要

The present invention relates to a method for deoxidizing molten steel by introducing a deoxidizing agent into a molten steel from a converter to a ladle, and its object is to provide a molten steel deoxidation method having excellent deoxidation efficiency.;In order to accomplish the above object, the present invention provides a method for deoxidizing aluminum deoxidized steel by introducing a deoxidizer into a ladle furnace from a converter to a deoxidizer, wherein the deoxidizer comprises calcium carbide and aluminum, The carbide is set at 40-80% and the aluminum is set at 20-60%. The charging time is completed before calcium carbide is introduced into aluminum and the casting proceeds in the range of 15-60%, and calcium carbide deoxidizer The method of claim 1, wherein the deoxidation is carried out before the start of excrement or before the excrement reaches 30%.
