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。

During May 1966, the № 1 blast furnace (576m~3) of the Capital Iron & Steel Co., through 45% powdered coal injection at a high blast temperature, large blast volume, and enriched blast got a remarkable low coke ratio of 336 kg per ton of pig iron. Based upon the experiences developed by the Capital Iron and Steel Co., together with the recent development of B. F. practice in other countries, it is proposed that the trend of best B. F. operating practice will be: high quality raw materials, large blast volume (>2.5m~3/min·m~3 furnace volume), high powdered coal injection ratio (>40%), high blast temperature (>1200℃), high ratio of oxygen enriched blast (>25%), high top pressure (>2kgf/cm~2).

Analysis of causes of thermal hysteresis in injecting fuels through tuyeres given in the literature doesn't consist with the practice. Based on theoretical calculation and analysis, four causes of the thermal hysteresis are recognized: 1, There is a decrease in theoretical heating temperature due to heating, gasification and decomposition of the injected fuel. Owing to the fact that the heat transferred to the hearth is reduced, a "Chilling" effect is observed. Increase in gas and heat content of gas makes the burden being heated better, which results in a thermal hysteresis; 2, Rate of burning of the carbon in injected fuel in the hearth is low; 3, Hydrogen in the injected fuel replaces the fixed carbon in the direct reduction zone; 4, Part of the hydrogen in the injected fuel and carbon monoxide formed from injected fuel take parts in the indirect reduction.

对风口喷吹燃料热滞后现象原因分析,现有文献的分折与生产实践是有矛盾的.通过理论计算和分析认为热滞后有以下四个原因:1.喷吹后由于喷吹燃料的加热、汽化、分解,使理论燃烧温度降低,全部煤气留给炉缸热量减少,造成"先凉".由于煤气量及煤气热含量的增加,使炉料加热得更好,形成热滞后.2.喷吹燃料中的碳在炉缸的燃烧率低.3.喷吹燃料中的氢在直接还原中代替固体碳.4.喷吹燃料中的一部分氢和喷吹燃料生成的一氧化碳参加间接还原反应.
