摘要
文章开展了包钢带式球团配加外购高硅矿可行性试验,分析了在现有带式球团生产铁料配置基础上,配加外购高硅矿后生球、干燥球、成品球的性能变化。结果表明,包钢带式球团配加外购高硅矿生产氧化球团矿是可行的。包钢带式球团生产配加5%~10%的外购高硅矿后,生球性能满足包钢球团生产工序要求,氧化球团矿铁品位变化不大,维持在63.20%左右。包钢带式球团生产在白云鄂博铁精矿配比为50%和55%条件下,配加5%~10%外购高硅矿时,建议适当提高球团生产的焙烧温度,此时生产出的氧化球团矿抗压强度高于2500 N,还原膨胀率均低于20%,满足高炉生产要求。
In the paper,the feasibility test of adding purchased high-silicon ore in pellet grate of Baotou Steel is carried out to analyze the changes of performances for green pellets,dry pellets and finished pellets after adding purchased high-silicon ore based on existing configuration of producing iron charge with pellet grate.The results showed that it was feasible to produce oxide pellet by adding purchased high-silicon ore in pellet grate of Baotou Steel.The performances of green pellets could meet the requirements of production processes for pellet of Baotou Steel and changes of grade of iron for oxide pellet are not great,which maintains at around 63.20%after adding 5%~10%purchased high-silicon ore in production with pellet grate.It is suggested to appropriately increase calcination temperature of pellet production in production with pellet grate of Baotou Steel under the condition that proportions of iron ore concentrate of Bayan Obo are 50%and 55%as well as adding 5%~10%purchased high-silicon ore.The compressive strength of oxide pellet produced is over 2500 N and reduction swelling is below 20%,which could meet the requirements of blast furnace production.
