转杯法粒化属于干法粒化的一种,这种方法不仅回收了高炉渣的显热,而且节约大量新水,不污染环境。针对转杯法粒化的热态试验,分析了高炉熔渣破碎的粒化机制,研究了转杯边缘线速度和熔渣温度对渣粒平均直径和质量分布的影响。研究结果表明:随着转杯边缘线速度的提高,渣粒平均直径逐渐减小,渣粒向远离转杯的方向分布;当线速度超过6 m/s时,渣粒平均直径的变化随线速度的提高趋于平缓;当熔渣温度在1 400~1 500℃范围内时,熔渣温度对渣粒平均直径和质量分布没有影响。
The rotor granulation is a type of dry granulation, this method not only recovered the sensible heat of blast furnace slag, but also save a lot of new water, do not pollute the environment. Aiming at the hot test of rotor granulation, the granulation mechanism of blast furnace slag is analyzed, and the influence of rotor edge line speed and slag temperature on the average diameter and mass distribution of slag is studied. The results show that with the increase of the linear velocity of the edge of the rotor, the average diameter of the slag particles decreases and the size of the slag particles distributes away from the rotor. When the linear velocity exceeds 6 m / s, When the temperature of slag is in the range of 1 400 ~ 1 500 ℃, the slag temperature has no effect on the average diameter and mass distribution of slag.
