苏联Носкоъа,T.B.撰文介绍了国外用粉剂进行钢水炉外脱硫的情况。文章认为: 1.在中性气体流中喷入粉剂进行钢水的炉外脱硫是提高生产技术、经济指标和改善钢质量的一种有效方法。 2.在工业条件下,于35—300t的钢包内用粉剂脱硫,喷吹时间为3—20min,喷粉速度为12—80kg/min。 3.为了脱硫、改变非金属杂质的形状和组成,喷入硅钙粉、石灰和萤石（即CaO—Al_2O_3—CaF_2）三元混合物。
Soviet Union Носкоъа, T.B. The article describes the foreign use of molten steel furnace outside the desulfurization situation. The article holds the following: 1. Spraying the powder into the neutral gas stream for out-of-furnace desulfurization of molten steel is an effective method to improve the production technology, economic indicators and improve the steel quality. 2. In industrial conditions, in the 35-300t ladle with powder desulfurization, blowing time of 3-20min, dusting speed of 12-80kg / min. 3. In order to desulfurize and change the shape and composition of non-metallic impurities, spray into the ternary mixture of calcium silicate, lime and fluorite (ie, CaO-Al_2O_3-CaF_2).
