由于大高炉是中国高炉炼铁先进技术的集中代表,大高炉具有单位容积投资经济、能耗低、环境负荷低、劳动生产率高的优点。为了给中国大高炉及其他类型高炉生产提供有效的参考及对比,选取中国21座4 000m3及以上高炉2016年1—6月部分生产技术指标进行分析,从生产、操作参数及原燃料等方面剖析大高炉生产指标和技术特点。并通过分析2016年上半年的中国大高炉生产指标,针对性地提出一些建议,供各企业参考。
Because the large blast furnace is the centralized representative of the advanced technology of blast furnace in China, the large blast furnace has the advantages of economic investment per unit volume, low energy consumption, low environmental load and high labor productivity. In order to provide an effective reference and comparison for the production of blast furnaces and other types of blast furnace in China, some production technical indicators of 21 blast furnaces with 4,000m3 or above in China from January to June 2016 were selected for analysis. Production, operating parameters and raw materials were analyzed Large blast furnace production indicators and technical characteristics. And by analyzing the production targets of China’s large blast furnace in the first half of 2016, some suggestions are put forward for reference of various enterprises.
