Dust removing fan is the key equipment of blast furnace production system. If there is abnormal vibration of fan equipment, the fault alarm would be triggered. As a result, there is not dedusting air volume in the environmental dedusting system so as to cause such environmental pollutions as flying dust. In the paper, it is proposed the causes and solutions for vibration fault of motor for dust removing fan for blast furnace by taking the basic principle of “high efficiency, high quality, low cost, green and environmental” as well as elaborated strengthening method for foundation bolt of motor and how to solve the problem of motor vibration with the six-point positioning principle. This method has been validated through field practices, which could effectively prevent and solve the problem of unnatural vibrations for dust removing fan.
