在钢铁工业的节能减排形势下，首钢开展了高炉高风温试验研究。2009年高风温试验情况表明，迁钢2号高炉连续4个月月均风温突破1270℃，实现年均风温12587℃，达到了高炉生产降低焦比和提高煤比等目标。采用对比分析法总结分析了高风温试验前、2008年和2009年迁钢2号高炉的试验数据， 2009年实现1280℃高风温下的热风炉、高炉等操作技术，研究了助燃空气温度、煤气预热温度、煤气热值、煤气流量和燃烧送风时间等参数对高风温的影响，提出了高风温随其影响参数的变化规律。
With the situation of energysaving and emission reduction in steel industry, commerical test of high blast temperature in Shougang was carried out in 2009. The results show that, monthly average blast temperature on Qiangang′s No2 blast furnace breaks through 1270℃ for four months continuously, yearly average blast temperature about 12587℃ is realized, the aim to lower coke ratio and high coal ratio of blast furnace production is obtained. Operative technique of hot blast stove and blast furnace in high blast temperature to reach 1280℃ on Qiangang′s No2 BF in 2009 was summarized and analyzed with contrast analysis method, effect of parameters such as combustionsupporting air temperature, preheated gas temperature, gas heat value, gas flux, combustion and blast time on high blast temperature, and the change laws of high blast temperature with its impact factor were put forward.
