作者对我国机械行业27个省、市、自治区的具有代表性的67座冲天炉的数据进行了处理,用数理统计及对比分析的方法对大双冲天炉熔炼的主要工艺参数和技术经济指标进行了分析、探讨,并将调查结果与发达国家的熔炼水平进行了对比,指出了在原材料质量比国外相差较大的情况下,我国大双冲天炉熔炼技术水平已接近世界先进水平。同时,结合近年来国内外冲天炉熔炼技术的新发展,对我国冲天炉熔炼技术的发展前景进行了展望。
The author has processed 67 representative cupola data of 27 provinces, municipalities and autonomous regions in our country’s machinery industry. The main process parameters and technical and economic indexes of big cupola furnace were analyzed by mathematical statistics and comparative analysis Analyzes and discusses the result of the survey and compares the result of the survey with the level of smelting in developed countries. It points out that under the circumstance that the quality of raw materials is greatly different from that of other countries, the smelting technology of the big twin cupola in China is close to the world advanced level. At the same time, combined with the new development of cupola melting technology at home and abroad in recent years, the prospects for the development of cupola melting technology in China are prospected.
