D—9高温风机是我厂球团生产用的主要大型风机之一。它用于抽均热段的风箱废气和一部分焙烧段废气并作为焙烧炉和抽风干燥热风助燃用的风机。该设备能否正常运转对完成球团矿生产任务的关系甚为密切。自1985年安装使用以来,由于风机叶片材质不易解决,所订转子亦不能按时交货。因此磨损后只能用治标的方法修修补补以维持生产。当我们提出叶片的代用材质订货时,风机厂不予受理;拟委托别的厂家制造,又因
D-9 high-temperature fan is one of the major wind turbines used in our pellet production. It is used for pumping the soaking section of the blower exhaust gas and a portion of the roaster exhaust gas and as a roasting furnace and ventilation drying hot air combustion fan. The normal operation of the equipment is very close to the task of pelletizing production. Since installation and use in 1985, due to the fact that the material of fan blades is not easy to solve, the ordered rotors can not be delivered on time. Therefore, only after the wear and tear of the method of repair and repair to maintain production. When we put forward the alternate material leaf orders, the fan factory will not be accepted; to be commissioned by other manufacturers, and because
