风口前焦炭燃烧所引起的炉料下降,是整个高炉料柱运动的前导,是决定高炉降料过程的主要因素,大型高炉的炼铁工作者曾对高炉风口前焦炭燃烧过程进行了专门研究,从高炉解剖到采用现代化高速摄影等科学研究方法获得了成功的经验,对现场生产起了指导性的作用。我国中、小型高炉由于受技术设备的限制很少进行此项工作,单纯凭热工检测仪表 The reduction of charge caused by the combustion of coke before the tuyere is the precursor to the movement of the blast furnace column. It is the main factor that determines the blasting process of the blast furnace. The ironmaking workers of the large blast furnace have conducted a special study on the combustion process of the coke before the tuyere. Blast furnace anatomy to the use of modern high-speed photography and other scientific research methods have been successful experience, on-site production has played a guiding role. China’s small and medium-sized blast furnace due to technical equipment restrictions rarely carry out this work, simply by thermal instrumentation
