各国炼铁工作者对高炉风口前焦炭燃烧过程的研究,已经进行了许多年,对燃烧过程的了解已逐步深入,特别是近十几年来的进步更为显著。焦炭燃烧理论的改变,各种因素对燃烧带的影响也正在进行新的探讨。鞍钢在1962～1963年进行了高炉炉缸研究工作。这一工作是在鞍钢九号高炉进行的。研究期间全部使用自熔性烧结矿,常压操作及冶炼炼钢铁,风量1760-2050米~3/分,风温975-1029℃,风压1.15-1.19公斤/厘米~2,渣量约750公斤/吨生铁,渣碱度1.048-1.10(cao/sio_2),炉况很顺行。经过一年多的
The research on the combustion process of coke before blast furnace tuyere in various countries has been going on for many years. The understanding of the combustion process has been gradually deepened, especially in the recent ten years. Changes in coke combustion theory, the impact of various factors on the combustion zone is also undergoing a new discussion. Anshan Iron and Steel from 1962 to 1963 blast furnace hearth research work. This work is carried out in Anshan Iron and Steel No. 9 blast furnace. During the study, all self-fluxing sintered ore was used, atmospheric pressure operation and smelting steelmaking, air volume 1760-2050 m ~ 3 / min, air temperature 975-1029 ℃, wind pressure 1.15-1.19 kg / cm ~ 2, the amount of slag about 750 Kg / tonne pig iron, slag alkalinity 1.048-1.10 (cao / sio_2), the furnace is very smooth.
