Abstract:The troubles of spot corrosion and peeling off of the delivery shaft gear of the dry quench coke lifting and speed reduction machine are systematically analyzed and the origin of the trouble is determined and a lot of improvement work have been carried out including increase of the hardness of the gear surface and improvements in the working condition and maintenance and repair work in the later stage. The performance of the e- quipments of the dry quench coke lifting and speed reduction machine and running condi- tions have been greatly improved since revamp work is carried out.
Keywords:dry quench coke  spot corrosion  peeling off  impact load
