摘要: 提出修正一般文献中关于保証还原和热量供应的理論碳量消耗的图解。应用冶金原理上浮士体的理論对焦比进行計算,提出了保証热量供应的曲线。从图解推断有可能在适当的原料条件下,把焦比降到450公斤左右。
Abstract:A modified diagram of theoretical requirements of carbon in ore reduction and heat supply for iron smelting has been proposed. The carbon requirements for reduction of Fe_3O_4 and that of wustite under different degrees of direct reduction of wiistite are separately considered in the proposed diagram. It is evident that the heat requirement varies with the degree of direct reduction, and is different from that conventionally adopted by some workers.The proposed diagram indicates the possibility of reducing the coke ratio to about 450 kg/ton of pig-iron, by proper preparation of raw materials, by working with a moderate driving rate under a favourable distribution of ascending gas currents across the furnace cross section to improve the gas utilization and by lowering the starting temperature of reduction of wustite.In actual practice, a surplus of reducing agents above the equilibrium is required, in order to control a proper rate of reduction; and stronger peripheral and central gas currents are required for smoother operation. Thus, the lowest possible coke ratio and the degree of direct reduction are usually higher than that theoretically required for minimum carbon supply, and can only be attained with easily reducible sinters or pellets.
