对济钢 2号球团竖炉进行了热工测试 ,其炉内纵向压力、温度、气氛的测定结果表明 :济钢2号球团竖炉炉内冷却带有部分气流沿导风墙向上流经焙烧带 ,焙烧带属弱氧化气氛 ,炉内有二次升温现象 ,且高温点接近导风墙的下沿 ,炉内的均热带几乎消失。竖炉的热平衡测定结果表明 :采用竖冷器继续冷却是成功的 ,但竖冷器余热的利用有待进一步研究。 Thermal tests on the shaft furnace of No. 2 pellet of Jigang were carried out. The results of the longitudinal pressure, temperature and atmosphere in the furnace showed that the cooling in the shaft furnace of No. 2 pellet of Jinan Iron and Steel Company The roasting zone, roasting zone is a weak oxidizing atmosphere, the furnace has a secondary heating phenomenon, and the high temperature point near the lower edge of the wind wall, the furnace almost disappeared. The results of thermal equilibrium measurement of shaft furnace show that it is successful to use vertical shaft cooler to continue cooling, but the utilization of residual shaft heat exchanger needs further study.
