摘　　要：为了优化马钢竖炉球团润磨工艺参数，研究了润磨参数对球团过程的影响。试验结果表明，在马钢条件下，混合料适宜的润磨水分、润磨时间分别在5％～6％、10～12min，适宜的润磨比例在70％水平，适宜的预热、焙烧时间在15～18min；适宜的预热、焙烧温度分别在900℃～950℃、1200℃～1250℃。试验还表明，生球水分低于9．5％时，其爆裂温度均高于600℃。In order to improve parameters of shaft pelletizing,the influence of mix damp milling on palletizing process in Masteel was studied. The test result indicated that suitable H20 eotain of damp mining is at 5% or so,time at 10 - 12min,damp milling rate at 70% ,and suitable warm -up and baking time respectively at 15 - 18min;temperature at 900℃ -950℃ ,1200℃ - 1250℃. The test result also showed that when the H2O cotain of green ball is under 9.5% ,its shock temperature is above 600℃.
