球团竖炉的改进与高产 总被引:4,自引:4,他引:0
摈上来我国竖炉球团生产有很大的进步,但还存在许多需改进的地方,重点是生球的干燥。改进后8m^2竖炉年产可达50万t,16M^2竖炉年产可达80万t,新设计的16m^2竖炉年生产能力可达100万t。 相似文献

通常用在1.0~2.0m/s气流速度下,10%生球有裂纹或爆裂时的温度作为生球的爆裂温度。爆裂温度是评价生球质量的一个重要指标,它对球团生产尤其是竖炉球团生产至关重要。目前,生产球团矿有3种形式:竖炉、带式焙烧机、链箅机-回转窑。对于带式焙烧机与链箅机一回转窑,可以根据生球的热敏感性选择合适的干燥工艺,而对于竖炉来说,干燥介质温度、 相似文献
