邯钢为提高高炉入炉料MgO含量,改善炉渣流动性,在链篦机-回转窑氧化球团生产中配加10%左右高镁铁精矿,提高球团矿MgO含量达1.5%±0.1%,以减轻烧结生产的提MgO压力。通过严把进厂原料质量关,加强生产管理,抓好主控、造球等关键岗位的精细化操作,合理控制热工制度等一系列措施,使含MgO球团矿转鼓指数达到97%以上,抗压强度大于2 500 N/个,满足了炼铁需求。
In order to improve the slag MgO content and improve the slag fluidity, Handan Iron and Steel Co., Ltd. added about 10% high-magnesium iron concentrate to the grate-rotary kiln oxide pellet production to improve the pellet MgO content to 1.5% ± 0.1% , In order to reduce the sintering pressure of MgO. By strict quality control of raw materials into the plant, strengthen production management, do a good job of master control, pelletizing and other key positions of the fine operation, reasonable control of the thermal system and a series of measures to make the drum index of MgO pellets to reach 97% Above, the compressive strength is greater than 2 500 N /, to meet the ironmaking needs.
