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.

In this article a method to calculate the heat transfer via the neck tube is presented. As the function of temperature for the thermal conductivity of the neck tube and the specific heat of the vapor have been considered in this method, more accurate results can be obtained. The paper shows the relations between the heat current reaching the cold end of the neck tube of stainless steel and german silver for liquid helium, liquid hydrogen and liquid nitrogen container and the dimention rate of the tube, and the...

In this paper, in addition to air helium is used as a dust carrying medium in the test, and experimental studies about the effect of gas properties on the efficiency of dust collection by granular bed filters are made. The conclusion: The greater the dynamic viscosity, the lower the efficiency. Furthermore, with the increase of the grain size of filling material and the gas current velocity, such difference become more significant.
