| 摘 要： | 利用硫铝酸盐水泥作为粘结剂,采用水硬化球团加工工艺,对冶金过程的二次资源进行了成球性能研究。研究结果表明:在70%硫酸渣、20%除尘灰和10%精矿粉原料条件下,添加6.5%的硫铝酸盐水泥和1.2%的复合粘结剂,能够获得粒度组成和强度均较理想的小球作为烧结料。该项成果的特点是带入原料的S iO2大量减少,水硬化球团养护期大幅度缩短,在重钢集团铁业公司取得了良好的生产效果。

| Abstract: | It is conducted a research on the pelletizing ability of metallurgical solid wastes using water hardening pellet process and with sulphoaluminate cement as a binder.The results show that the pellets with rational size composition and strength,which will be used as sintering material,can be got under conditions of 70% sulphuric acid residue,20% dedusted ash and 10% clean ore powder,as well as adding 6.5% sulphoaluminate cement and 1.2% binder.This achievement features much less SiO_2 in raw material and much... |
