查询词典 coal

This research is a new low cost method of producing abrasive grit. It is to put the iron ore concentrate, coal powder, hydrated limed and addition agent together to make coal mixed pellet in prior which is rapidly auto-reduced in high temperature and kept about 10min above 1350℃, and then furnace cooled. The 2CaO·SiO2 of slag phase change、volume increase and natural bloom in reduction process. Finally we obtain no-slag abrasive grit through screen separation , in which the iron yield can be above 90%,the sulfur content can be below 0.05% and carbon content is lower than 4.0%.

本研究是一种全新的低成本生产铁粒的方法，它是将铁精粉、煤粉、消石灰和添加剂预先制成球团，在高温下迅速加热还原，在1350℃以上保温10分钟后随炉冷却，渣相中2CaO·SiO2在冷却过程中发生相变，体积膨胀而自然粉化，通过筛分便可以得到不含炉渣的铁颗粒，铁的收得率在90%以上、S≤0.05%、C在4.0%左右。
