For the investigation of a series of problems in connection with the behaviour of fluorine inblast-furnace smelting,an experimental blast-furnace of an effective volume of about 1 m~3 wasbuilt at our Institute by November 1955 together with the necessary auxiliary equipment.Pao-Tou iron ore,which contains fluorite as one of its chief gangues,was smelted in our experimentalblast-furnace with and without previous sintering,and the planned experiments were completed intwo campaigns which lasted for 22 and 36 days respectively.The smelting characteristics ofour experimental blast-furnace are herewith reported together with data on material balance of allthe constituents including fluorine.It was found that nearly all the fluorine went into the slag,while the fluorine content of tht blast-furnace gas was exceedingly low despite the rather highpercentage of fluorite in the charge.

为了研究包头铁矿的冶炼特性及由于矿石含氟所引起的一系列问题起见,我所于1955年11月筹建了有效容积约为1米~3的实验高炉一座及全部附属设备。1955年11月30日至12月8日及12月20日至12月24日进行了二次试炉。经过设备上的改进后,于1956年1月20日至2月11日及4月23日至5月29日进行了二次冶炼试验,获得设计上所要求的的主要数据后停炉。在实验高炉冶炼试验期间并进行了4次物质平衡的试验。结果发现绝大部分的氟进入炉渣中,进入炉尘中的氟石多,而高炉煤气中的氟极低.

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...

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.

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。

Theoretical coke rate means the necessary amount of coke to satisfy the thermal and chemical requirements under given conditions of raw materials, blast temperature, etc. The newly proposed method is characterized by combination of material and heat balance into one equation, and by that, the only thermal income is the heat of combustion before the tuyere with subtraction of heat carried away by the hot top gas. With this thermal balance, the necessary tuyere carbon is found. By adding to this carbon the solution...

Theoretical coke rate means the necessary amount of coke to satisfy the thermal and chemical requirements under given conditions of raw materials, blast temperature, etc. The newly proposed method is characterized by combination of material and heat balance into one equation, and by that, the only thermal income is the heat of combustion before the tuyere with subtraction of heat carried away by the hot top gas. With this thermal balance, the necessary tuyere carbon is found. By adding to this carbon the solution carbon in pig iron and direct reduction carbon, the total carbon is finally obtained.By partial differentiation, a convenient and practically accurate method is derived for calculating effects of different factors on coke rate. Calculations for some Chinese and Japanese blast furnaces are given to show how this method might be used to examine operational efficiency, to calculate effects on coke rate of new technology like fuel injections through tuyere, and used for design purposes. Comparisons of this method with others like that of Runm and Pavlov are briefly given.

理論焦比是指在一定原料和风溫条件下渗碳、发热和还原所需的焦炭;現有各种計算方法的缺点;以风口热函減去炉頂煤气热函作为唯一热量收入的热平衡計算方法,以物料平衡和热平衡結合为基础,利用偏微分找出的計算各种因素对焦比影响的方法。
