摘　　要：除尘风机是高炉生产系统的关键设备,风机设备如果振动异常会触发故障报警,致使环境除尘系统没有除尘风量而造成扬尘等环境污染。文章以“高效率、高质量、低成本、绿色环保”的基本原则,提出炉前除尘风机电机振动故障产生原因以及解决办法,详细阐述了电机地脚螺栓加固方法以及如何利用六点定位原理解决电机振动问题。此方法已通过现场实践验证,可以有效预防和解决除尘风机非自然振动的问题。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.
