球团矿低温粉化性能的实验探讨
首发时间:2015-03-16
摘要:本文主要对球团矿的低温粉化性能进行实验研究。通过KSZ-03矿石冶金性能综合测定仪和转鼓等设备对球团矿的低温还原粉化性进行性能检测,确定其低温还原粉化性及粉化程度的影响因素。结果表明,当气体条件保持不变,提高低温粉化实验的还原气体流量,球团矿还原粉化程度明显提高;当还原温度达到500 ℃,球团矿低温粉化现象最严重,低温粉化度最高,在此基础上温度的升高和降低都会降低粉化程度。

Experimental Study of the Low Temperature
Abstract:This article mainly discusses the pellets of low temperature pulverization performance experiment research. Through KSZ-03 ore comprehensive metallurgical properties tester and drum devices such as low temperature for pellets in index for performance test, to determine the low temperature reduction desintegration and the influence factors of degree of pulverization. Results show that when the gas conditions remain unchanged, and improve the low temperature pulverization experiment of reduction gas flow, degree of pellets reduction desintegration also increased significantly; When the reduction temperature reaches 500 ℃, low temperature pulverization phenomenon is the most serious, and temperature higher than 500 ℃ and below 500 ℃ will reduce the degree of pulverization.
Keywords: metal material, pellets, low temperature pulverization, restore
