<p>PURPOSE:To stably produce stainless steel extremely low in oxygen content by adding metallic Ca or the like to a slag material essentially consisting of quick lime and fluorite and using the conventional stainless steel as an electrode. CONSTITUTION:A slag material obtd. by preparing quick lime and metallic Ca or the like and contg. 20 to 35wt.% Cab, 0.3 to 3% total SiO2 and Ca; 1.36X(total SiO2) to 1.36X(total SiO2+2)% is used, stainless steel contg. 0.15 to 1.0O% SiO is used as an electrode material and electroslag remelting is executed in a nonoxidizing atmosphere. In this way, the high purity stainless steel having about <=10ppm oxygen content can be obtd.</p> |
