摘要： PURPOSE: A method for refining a very low temperature carbon steel having an excellent cleanness by preventing re-oxidization of very low temperature carbon steel of which a carbon element is less than 70ppm. CONSTITUTION: A molten steel(2) is moved to a ladle(1) from a converter in a non-oxidization state. The ladle is transferred to a refining equipment capable of taking a powder body, and a CaO power body such as CaO, CaCO3, Ca(OH)2 and so on is taken by dipping a lance in the molten steel. The molten steel is transferred to RH, decarbonized, deoxidized and returned so that the re-oxidization of the very low temperature carbon steel is prevented. Thus, the clean degree of steel is improved, and a nozzle is not cogged. Further, aluminium is saved.
