日本川崎公司提高卷板用连铸板坯清洁度的措施是 :( 1 )铁水预处理。在高炉出铁沟进行脱硅 ,在鱼雷型铁水罐内扒除脱硅渣后进行脱磷 ,然后再进行脱硫。铁水 [Ｐ]从 0 1 5%降到 0 0 2 %～0 0 5% ,转炉钢水受磷污染的可能减少。( 2 )控制炉渣成分最佳化。由于铁水经过预处理 ,
Japan Kawasaki company to improve the rolling plate with continuous casting slab cleanliness measures are: (1) hot metal pretreatment. Desiliconization is carried out in the blast furnace trenches, dephosphorization is carried out after removal of desiliconized slag in a torpedo-type hot metal tank, and then desulfurization is carried out. The hot metal [P] is reduced from 0 1 5% to 0 0 2% ~ 0 0 5%, and the molten steel in converter may be reduced by phosphorus pollution. (2) control of slag composition optimization. As the hot metal after pretreatment,
