摘　　要：文章针对135t钢水罐耳板轴开裂失效的问题,结合钢水罐本身的外形结构及工艺特点,通过对钢水罐耳板轴的工作环境进行受力分析,找出钢水罐耳板轴开裂失效的原因,然后针对失效原因采取措施,彻底消除钢水罐耳板轴开裂失效的设备隐惠,并运用强度理论,对钢水罐的本体耳轴及吊耳装置的耳板轴进行强度校核,确保设备的本质安全。Fracture appeared on a lug plate shaft of 135t ladle.Combined with ladle structure and process characteristics,the failure reason was found out through making a force analysis on the working environment of the lug plate shaft.The hidden danger is eliminated thoroughly.By means of strength theory,the strength of the ladle body trunnion and the lug plate shaft of the lug device are checked in order to ensure the essential safety of the equipment.
