摘要
采用均匀设计的试验设计方法对天津钢管公司炼钢厂钢包喂线工艺进行了优化研究。研究表明：试验条件下，较低的喂线速度和较大的喂线量有利于喂线后钢水中钙的回收率ηＣａ的提高，钢中锰和铝的存在有利于ηＣａ的提高；喂线量和钢水温度对连铸中间包内钢水的总钙含量Σ［Ｃａ］ＴＤ具有正面影响，喂线后钢水的停留时间和喂线前钢水的硫含量对Σ［Ｃａ］ＴＤ具有负面影响。研究还给出了连铸中间包内钢水中总钙含量的预报方程。
The research on Ca-Si wire feeding optimization in ladle was accomplished in the steelmaking plant at Tianjin Pipe CorpThe main results of the study are as follows:low feeding speed,large addition of Ca-Si wire,high manganese and total aluminum content in steel are favorable to improve the yield of calcium under the experimental conditionsWith the increase of added CaSi,the temperature of liquid steel,and the decrease of sulfur content in steel and holding time of steel in ladle,the calcium content of liquid steel in tundish risesIn addition,a regression equation is given to predict the total calcium content in liquid steel in tundish
