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...

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.

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。

比较了两种人造块矿的还原性:自熔性烧结矿和铁精矿制成的自熔性球团矿。使用喷吹或不喷吹焦炉煤气的高炉煤气进行了实验室的还原实验。为了估计自熔性球团矿的可能焦比起见,应用自熔性烧结矿的实际数据校正实验窒得到的结果。焦比由两个联立方程式解出,一个方程式为直接江原Fe_xO,MnO,P_2O_5及SiO_2,热量供应及渗碳所需的焦炭量;另一个方程式为间接还原Fe_xO的焦炭量乘以(1+ΔC%/100)外加渗碳所需的焦炭量。ΔC%是实际焦炭消耗量超出保证间接江原Fe_xO的理论需要量,对保证间接还原Fe_xO的理论需要量的百分比比值。对降低ΔC来降低冶炼自熔性烧结矿的焦比,进行了估计。认为用CO/CO_2及焦比量度高炉操作效率不如用ΔC。
