Abstract The design focuses on the contents of 1080m3 blast furnace process design, the design of 1080m3 blast furnace mainly include calculation, material balance calculations, thermal balance calculation, furnace figure design and the selection of blast furnace lining。
Empirical formula of ironmaking from domestic and foreign was used in thedesign for furnace figure design to make the blast furnace to obtain good technical and economic index and prolong furnace life; the maincontents of ingredients calculation iscalculation
ofthe need to consume the ore, flux and fuel when smelting a ton of pig iron;According
to the law of conservation of matter, the balance of hydrogen, carbon and oxygen balance equations were established to analyze and study the process of blast furnace。 In accordance with the laws of Gass, according to its original shape when into the furnace and the final form of the material when baked, calculate the heat of produce andconsumption for thermalequilibriumcalculationtounderstandtheheatconsumptionstateofthe blast
furnace;About blast furnace lining, the hearth and bottom with the composite structure of
carbon and ceramic cup , bosh, belly and the lower part of the shaft is mainly used the refractory of clay bricks and high alumina brick and cast steel cooling stave。
Keywords: blast furnace; ingredients calculation; material balance calculation; thermal equilibrium calculation;
