摘　　要：在无锡钢厂LFV—40型钢包炉上进行34炉工业性试验,提出了该钢包炉合理的吹氩制度。探讨钢包炉底吹氩气的搅拌功与钢液中[H]、[N]、[O]和非金属夹杂物的脱除率以及脱硫率的关系。试验结果表明:对于脱气,搅拌功大些好,但对于脱除夹杂物和脱硫,搅拌功有一最佳范围,合理的搅拌功为ε_M·t=(140～220)×10~3J/t。Industrial test has been conducted 34 heats in a LFV 40 ladle furnace at Wuxi steelworks. The relations of stirring power of the bottom blowing argon with removing rate of [H], [N], [O] and non-metal inclusions and desulfurization have been discussed. The test results show that for degasing a big stirring power is needed, but for the removing of iuclusions and desulfurization, stirring power has a optimum range. The rational stirring power is ε'_M·t=( 140～220)×10~3 J/t.
