Experimental study on impact of iron coke hot briquette as an alternative fuel on isothermal reduction of pellets under simulated blast furnace conditions

AbstractIn order to realize comprehensive and massive treatment of boron mud secondary resource, fundamental study on boron mud applied to oxidized pellets production as additive was carried out in the paper under laboratory conditions. The effects of boron mud on the performance of oxidized pellets were investigated systemically, and boron mud was combined with other boron-rich material innovatively. The results showed that, within certain limits, boron mud can improve properties of oxidized pellets. The bentonite content decreased to 0.3 % when adding 1.0 % boron mud additive and the pellets met blast furnace requirements. With the combination additive content 0.8 %, bentonite content can be further decreased to 0.2 %, and the pellets properties were better than base pellet. Therefore, it was an effective way to reduce environmental pollution and optimize blast furnace operation by developing boron mud secondary resource as pellets additive.

In the blast furnace production process, the high iron content in the sludge produced by collecting, Iron can be used as recycled raw materials. Experimental study found that the use of magnetic roasting - weak magnetic iron powder method of recovering technology is feasible. The optimum conditions are: the grinding fineness is 87%, calcination temperature is 750 °C, roasting time is 25min, magnetic current is 1.5A under conditions to obtain a grade of 59% recovery rate of 79.3% iron ore .
