The Study on Self-Pulverization Rate of Steelmaking Slag Modified and Reduced

More than one hundred million tons of steelmaking slag is produced annually in China. Bad grindability inhibits efficiency of using steelmaking slag which resulted a great waste. In view of this situation, various methods were carried out to improve the grindability so that to reduce the amount of waste and recycle the materials. Experiments were executed to compare the self-pulverization rate before and after the modification and deoxidization. Our study results indicate that by using the method of modification and deoxidization, which improves the self-pulverization of slag could be greatly improved.
