摘　　要：通过在１８ｔ钢包上进行的钢包密闭喷粉脱硫脱氮新工艺的试验表明：第１阶段脱硫 率达到５０％，脱氮率达到３０％；第二阶段脱硫率达到６５％，脱氮率达到４０％．该工艺钢液中硫质 量分数为４×１０－６，氮质量分数为１２×１０－６．Powder injection desulphurization and denitrification refining process with the ladle-cover was studied. The experimental results showed that in first stage, desulphurization ratio reached the 50% and denitrification ratio reached the 30%. In second stage, desulphurization ratio reached the 65% and denitrific-ation ratio reached the 40%. The process reduced sulphur of molten steel to 4× 10-6 and nitrogen of molten steel to 12×10-6. On the some time reduced the nitrogen. The experiment result supplied basic theory for the commerical test of the process.
