Abstract：The supporting roller shoes of rotary kilns are prone to overheating under long-term heavy loads,high temperatures,and alternating stress,significantly impacting equipment stability.The main causes of high temperature in supporting roller shoes include abnormalities in lubricant quality and quantity,insufficient cooling system efficiency,wear of the bearing bush,changes in liner plate clearance,abnormal operation of the hydraulic thrust roller,and misalignment of the kiln centerline.To address these issues,this paper proposes preventive and maintenance measures such as enhancing lubricant management,optimizing the cooling system,performing scraping repair on the bearing bush,adjusting the contact state of the supporting rollers,and regularly inspecting the kiln centerline.Additionally,a detailed emergency response plan has been developed.Practical cases demonstrate that systematic preventive and emergency measures can effectively control the temperature of the supporting roller shoes,ensure the long-term stable operation of the rotary kiln.
