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...

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.

Experiments on the dephosphorizatlon of well-deoxidized manganese steel(Mn13)containing high phosphorous by injection of CaC_2-CaF_2 powder using argon as a carrier gas through a submergedlance were made under reducing atmosphere in high-frequency induction furnace.The experimentalresults showed that the content of phosphorous in the steel can be lowered quickly and considerably andthe degree of dephosphorization can be as high as 74.7%.The decomposition of CaC_2 in the steel isaffected by the initial carbon...

Experiments on the dephosphorizatlon of well-deoxidized manganese steel(Mn13)containing high phosphorous by injection of CaC_2-CaF_2 powder using argon as a carrier gas through a submergedlance were made under reducing atmosphere in high-frequency induction furnace.The experimentalresults showed that the content of phosphorous in the steel can be lowered quickly and considerably andthe degree of dephosphorization can be as high as 74.7%.The decomposition of CaC_2 in the steel isaffected by the initial carbon activity and injection temperature.The most important factor affectingthe results of dephosphorization is the injection temperature.If the starting temperature of injectionis 1490℃ and the temperature drop is controlled as slow as possible,the best dephosphorizationresults can be achieved.The content of CaF_2 in the powder only has a little effect on the resultsof dephosphorization and the good results can be also obtained by using industrial fluorite.

在高频感应炉上以 Ar 为载气,向脱氧良好的 Mn13钢液喷吹 CaC_2-CaF_2粉料进行还原脱磷,可将钢液中含磷量迅速降低。脱磷率最高可达74.7%。喷入钢液中 CaC_2的分解受温度和钢中碳活度的控制。喷吹温度对脱磷率有极其重要的影响。开喷温度在1490℃左右并尽量减少喷吹过程中的温降,则可获得最好的脱磷效果。粉料中 CaF_2配比对脱磷效果关系不大。用工业萤石也可得到良好的脱磷效果。

The laboratory softening under load test and reducibility test were conducted with different kinds of pellets having different Fe content and basicity. As a result,the softening start temperature of pellets increased as basicity increasing. At lower roasting temperature region,the reducibility of pellets is also increased with basicity,but at higher roasting temperature region,the reducibility decreased as basicity increased from 0. 5 to 1. 0,In addition,rapid cooling would lead to the decrease...

The laboratory softening under load test and reducibility test were conducted with different kinds of pellets having different Fe content and basicity. As a result,the softening start temperature of pellets increased as basicity increasing. At lower roasting temperature region,the reducibility of pellets is also increased with basicity,but at higher roasting temperature region,the reducibility decreased as basicity increased from 0. 5 to 1. 0,In addition,rapid cooling would lead to the decrease of softening start temperature so the cooling rate of pellets should not be too high.

试验结果表明,球团矿的软熔开始温度随碱度升高而升高,在焙烧温度低时,还原率亦随碱度升高而升高,焙烧温度高时,由于渣相出现使CaO/SiO_2=0.5~1.0时还原率降低。急冷易导致软化开始温度降低,故冷却不宜太快。
