摘要
以烧结厂脱硫所产生的脱硫石膏和选铁后的铁尾矿为主要原料,对铁尾矿陶粒的配方和焙烧制度进行了研究。结果表明:尾矿、脱硫石膏、粉煤灰和煤粉的最佳质量配比为57.2%∶16.8%∶22.5%∶3.5%,在预热温度300℃,焙烧温度1110℃,焙烧时间30 min,冷却温度500℃的焙烧制度下烧制陶粒,性能满足GB/T 17431.1-2010的质量要求。
The paper studied the formula and roasting system of iron tailings ceramsite with desulfurization gypsum from sintering plant and tailing from iron ore dressing as the main raw material. The results showed that the optimum ratio of iron tailing, desulfurization gypsum, fly ash and pulverized coal is 57.2%∶16.8%∶22.5%∶3.5%, under roasting system of preheating temperature at 300 ℃, roasting temperature at 1110 ℃, roasting time for 30 min and cooling temperature at 500 ℃, the ceramsite performance meet the quality requirements of GB/T 17431.1-2010.
