本研究目的是为防止在连铸过程中氧化铝积聚而确定减少钢中钙加入量的可行性。共进行了6次工厂试验 ,试验中在二连浇或三连浇的第二包中加入钙 0 .1 4kg/t钢水 (从原来的 0 .1 9kg/t钢水减少到 0 .1 4kg/t钢水 )。从钢包和中间包中取全氧样来测定钢中的全氧量和氮含量。钢包中
The purpose of this study was to determine the feasibility of reducing the amount of calcium added to the steel in order to prevent the build-up of alumina during the continuous casting. A total of six factory tests were carried out in the second package of two or three continuous casting of calcium 0.14kg / t molten steel (from 0.91kg / t molten steel reduced to 0.14kg / t molten steel). Oxygen-like samples were taken from ladle and tundish to determine total oxygen and nitrogen content in the steel. Ladle
