Abstract

PURPOSE: To obtain stably and in low cost an ultra low sulfur steel by the process; in which molten steel desulfurized and deoxidized previously to below the specified concentration is received to ladle lined with basic refractory materials less than 20% in SiO2, and the wire material of 3 - 20 mmϕ containing Ca is added from above the ladle to the steel at a speed of 25 - 50 m/sec.
