高炉的能源消耗大约占钢铁工业的70%,确立高炉的低还原比操作技术非常重要。为了实现低还原比,可大量使用高反应性的焦炭,但是如何控制焦炭的劣化至关重要。为了用焦炭的反应试验来评价反应形态对焦炭劣化的影响,日本住友金属工 Blast furnace energy consumption accounts for about 70% of the steel industry, the establishment of low reduction of the blast furnace than the operating technology is very important. In order to achieve a low reduction ratio, a large amount of highly reactive coke can be used, but how to control the deterioration of the coke is crucial. In order to use coke reaction test to evaluate the impact of reaction morphology on the deterioration of coke, Japan Sumitomo Metalworking
