人工控制气象条件降低高炉焦比

Artificial Control Air Humidity to Reduce Coke Ratioof a Blast Furnace

高炉冶炼的重要能耗指标———焦比 ,存在着明显的季节性变化 ,而这种变化近似于某些气象要素的季节性变化。经分析发现绝对湿度与焦比的关系最为密切 ,通过试验 ,发现可以运用脱湿鼓风这种人工控制气象条件的方法降低焦比 ,为高炉创造四季如冬的最佳工艺环境 。

Coke ratio, an important energy consumption index of a blast furnace, changes with seasons as some meteorological elements, especially, absolute humidity. It is found that coke ratio of a blast furnace is related with the absolute humidity. Experiments show that coke ratio of a blast furnace can be reduced by artificial control air humidity, thus increasing economic benefit.
