摘要: 將粒度很細的含鋅鉛高爐粉塵和不含鋅鉛的轉爐粉塵混合造球,實驗表明,球團的最佳條件為造球時間20min,水分為21%;球團性能濕球和干球抗壓強度分別為15和25N/個,爆裂溫度為210℃。Abstract: The Zn-Pb-bearing dust from BF and LD dust without Zn were mixed and then made to pellets. The results show that the water content of 21% and time of 20 min, for pellets making were considered to be the best conditions. The compressing strength of moist pellets and dry pellets were 15 N/pellet and 25 N/pellet respectively. The decrepita-tion temperature of moist pellet was 210℃
