冲天炉是热效率最高的一种化铁炉,也是国内外最常用的铸铁熔炼设备。目前我国的冲天炉熔炼虽然基本上已能满足一般铸铁生产的要求,但还存在不少问题。根据我国的现实生产条件和能源情况,今后在相当长的一段时间内,国内铸铁熔炼仍将立足于冲天炉。因此,进一步研究分析目前我国冲天炉熔炼存在的问题,加强冲天炉先进技术的开发,对提高铸件质量,降低能源消耗,减少环境污染,都是很有意义的。为此,本文就与此有关的若干问题,作一些初步探讨。一、焦耗与熔耗的矛盾处理铸铁车间50％以上的能量消耗在熔炼上。几年 Cupola is the highest thermal efficiency of a furnace, but also the most commonly used cast iron smelting equipment at home and abroad. At present, although the cupola melting in our country basically can meet the general requirements of cast iron production, but there are still many problems. According to China’s actual production conditions and energy situation, in the future for a long period of time, the domestic cast iron smelting will still be based on Cupola. Therefore, further study and analysis of the existing problems of cupola melting in China and strengthening the development of advanced cupola technology are of great significance to improve the quality of castings, reduce energy consumption and reduce environmental pollution. To this end, this article on some issues related to this, make some preliminary discussions. First, the contradiction between coke consumption and melting cast iron workshop more than 50% of the energy consumption in the melting. several years
