高炉渣干法离心粒化实验研究

在高炉渣余热回收综合实验台上，研究高炉渣出料温度、粒化器转速等关键参数的变化对粒化颗粒粒径分布、球度等结果的影响，掌握高炉渣干法离心粒化的最佳运行参数，为高炉渣余热回收提供基础。结果表明： 高炉渣出料温度控制在1400-1450°C之间，粒化器转速为2000r/min以上时， 粒化颗粒的成球度良好，80%以上的颗粒粒径分布在2-5mm之间。

Experimental Study of Dry Granulation of Molten Blast Slag

based on experimental test-bed of blast furnace slag waste heat recovery, the paper studied on the changes of the key parameters such as blast furnace slag discharged temperature, the speed of the granulation device, which impacted on the results of particle diameter distribution and sphericity coefficient, so as to master the best operating parameters of the blast furnace slag dry centrifugal granulation, and to provide a experimental basis for blast furnace slag waste heat recovery. The results showed that: when the discharged temperature of the blast furnace slag is controlled in 1400-1450 ° C , and the speed of the granulation device is controlled above 2000r/min, there is a good sphericity of the blast furnace slag, and there is up to 80% particle diameter distribution of 2-5mm.
