概述了在１８ｔ钢包中喂金属钙包芯线的试验结果。在钢中加钙０．１０～０．６０ｋｇ／ｔ时，平均脱硫率４７％，最高脱硫率６８％，最低硫含量０．００９％，平均脱氧率３１％，钙的平均收得率２５％，金属钙线用量比硅钙线用量少５０％～７０％，比硅钙线节省５．４６元／ｔ，取得了较好的冶金效果与经济效益。
The experimental results of feeding metal cored wire in 18t ladle are summarized. The average desulfurization rate of 47%, the highest desulfurization rate of 68%, the lowest sulfur content of 0.009%, the average deoxidation rate of 31%, the average calcium recovery rate of 25% in the steel with calcium 0.10 ~ 0.60kg / t, , The amount of metal calcium line less than the amount of calcium silicate 50% to 70%, saving 5.46 yuan than the calcium silicate / t, and achieved good metallurgical results and economic benefits.
