修磨机砂轮爆片的原因分析及对策

Analysis and Countermeasures for Grinding Wheel Breakage of Slab Grinding Machine

通过现场取证,从砂轮压盘、安装方法、操作方法、砂轮质量等方面对造成砂轮爆片的原因进行分析,提出相应的预防及保护措施。实践证明:采取一定的保护措施后,砂轮爆片年均故障频次下降58%,爆片引发的设备年均故障时间减少80.7%,再未发生砂轮碎片伤人的险肇事故。

This paper analyzes the reasons for the debris of abrasion wheel from the platen, installation, operation and quality of the abrasion wheel with on-site evidences and puts forward related prevention and countermeasures. The practice shows that taken some measure, the fault frequency of debris of abrasion wheel has annually decreased by58%, and the time equipment broken cased by debris has decreased by 80.7%, and there is no accident which injured people.
