Right use the cardan shaft for the hot strip mill
Cardan shaft for hot strip mill is divided into roughing mill and finishing mill.Because of the great rolling force and the unstable torque, the yokes of universal shaft must select more than 42CrMo material as the foundation.After adjusting the microstructure through heat treatment process, the speed of this position for the cardan shaft is low,so usually once a week to inject the lithium grease to the shaft sleeve is ok.Then check the wear situation of the bushing linner, if the gap is larger than 5mm, the liner should be replaced.However, it is necessary to consider the selection of cardan shaft in finishing mill.The front three cardan shaft for roughing mill can be used to select the cardan shaft with lower balance level,or you can choose the cardan shafts have been repaired already, the general service life of more than 6 months.However,for the last two finishing mill parts,the cardan shafts need in high speed balance level.In our experience, a new cardan shaft's service life can reach more than 10 months,but the service life of the cardan shaft be repaired only can reach about 2 months, so it is recommended to use the new one.
The cardan shafts with WEICHENG brand —— the intermediate nozzle used in the manufacture of universal axis for hot rolling mill needs to be increased by 5-10mm between the common cardan shaft, so as to ensure the wear of the bracket position. This general use units are not aware of.
