| 摘 要： | 由于目前采用的水淬法工艺不能有效地回收利用高炉渣中的能量,因此针对转杯法炉渣粒化工艺,研究了转杯转速、直径和熔渣温度对破碎粒化后渣粒的平均直径和质量分布的影响规律.结果表明:渣粒的平均直径随转速的提高而减小;增大转速,渣粒将远离转杯,其质量分布更均匀.当转杯的转速小于1 000 r/min时,渣粒的平均直径随转杯直径的增大而减小,当转杯的转速大于1 000 r/min时,渣粒的平均直径几乎不随转杯直径变化.熔渣温度对渣粒平均直径和质量分布没有影响.

| Abstract: | A dry granulation experiment was done by means of a rotary cup atomizer for blast furnace slag instead of the currently used water quenching process because it is unable to efficiently recover the waste heat energy inside the molten slag.The influences of cup atomizer rotating speed,its diameter and molten slag temperature on the mean slag granule diameter and granules' mass distribution were investigated.The results showed that the mean granule diameter decreases with increasing rotating speed which will l... |
