【摘要】 熔融氯化镁作为镁热还原法(Kroll法)生产海绵钛过程中的副产品，蕴含着高品质的余热资源，为了有效地回收其热量，采用转杯离心粒化法将熔融氯化镁破碎成球形颗粒，研究了转杯转速和熔液质量流量对氯化镁颗粒的平均粒径、粒径分布的影响.结果表明：随着转杯转速的增加和熔液质量流量的减小，颗粒的平均粒径呈逐渐减小的趋势，较大直径的转杯能够获得更小尺寸的颗粒；颗粒粒径主要分布在0～2 mm,随着转杯转速的增加和熔液质量流量的减小，颗粒向小粒径方向集中.更多还原

【Abstract】 In order to recover high-quality waste heat resources from molten magnesium chloride which is a by-product of the Kroll production of sponge titanium, molten magnesium chloride was broken into spherical particles by rotary cup centrifugal granulation in this paper, and the influences of cup atomizer rotating speed and melt mass flow on the average diameter and particle size distribution of magnesium chloride were investigated. The results show that with the increase of the cup atomizer′s rotating speed and the decrease of mass flow, the average particle size gradually decreases and a larger diameter of the rotating cup can obtain smaller particles. The particle size is mainly distributed in the range of 0～2 mm and the particles are concentrated in the direction of smaller granule size with the increase of rotating speed and the decrease of mass flow.更多还原
