在炼铁高炉中,已广泛地使用热鼓风操作,使高炉的焦比大大降低,产量大大增加。有色冶金鼓风炉熔炼采用预热鼓风也获得了良好的结果。根据我厂的生产实践,再生铜鼓风炉利用热废气来加热空气,可使预热风的温度达250±50℃,从而强化了冶炼过程,使冶炼能力平均提高了6%,减轻了劳动强度和改善了技术经济指标。一、预热器的选择与设置废气的热利用形式,有蓄热式和传导式两种。由
In ironmaking blast furnaces, hot blasting operations have been widely used to greatly reduce the coke ratio of the blast furnace and greatly increase the yield. Non-ferrous metallurgy blast furnace smelting preheated blast also obtained good results. According to our factory’s production practice, the regenerative copper blast furnace uses hot exhaust gas to heat the air, so that the temperature of the preheated wind reaches 250 ± 50 ℃, thereby strengthening the smelting process, increasing the smelting capacity by 6% on average, reducing labor intensity and Improved technical and economic indicators. First, the choice of preheater and set the form of heat utilization of exhaust gas, regenerative and conductive two. by
