传统的高炉炼铁法,是将铁精矿制成烧结矿或球团矿入高炉炼铁。本法取消铁精矿的烧结工序,将铁精矿制成和散状料或生球团矿直接入高炉炼铁,烧结和冶炼同时在高炉内进行,相当于球团竖炉与高炉合二为一,简化了高炉生产工序。例如:生散状料在100m~3高炉生产中应用,生球团矿在50m~3高炉和20m~3高炉生产中应用,高炉炉况稳定顺行。获得很好的经济效益,生产技术经济指标见表1。计算结果表明,采用本法炼铁,吨
The traditional blast furnace ironmaking method, is made of iron ore sinter or pellet into the blast furnace ironmaking. This law to cancel the iron ore sintering process, the iron concentrate made of loose material or pellets directly into the blast furnace ironmaking, sintering and smelting at the same time in the blast furnace, equivalent to the pellet shaft and blast furnace combined As one, simplified blast furnace production process. For example: Raw materials are used in the production of 100m ~ 3 blast furnaces. The raw pellets are used in the production of 50m ~ 3 blast furnaces and 20m ~ 3 blast furnaces, and the blast furnace condition is stable. Obtain very good economic benefits, production technical and economic indicators in Table 1. Calculation results show that using this method of ironmaking, tons
