摘　　要：钢丝绳卷筒是集装箱起重机等大型机械设备中应用颇为普遍的构件之一,是在完成钢板拼接后焊接而成,由于钢板和焊材的含碳量存在差异,淬火之后,焊缝处绳槽的硬度低于钢板的硬度,无法完全符合图纸要求,致使卷筒焊缝处表面的磨损相比于其他位置的绳槽磨损更为迅速。Steel wire rope drum is one of the most common components used in large mechanical equipment such as container cranes.It is welded after the completion of steel plate splicing.Due to the difference in carbon content of steel plate and welding material,after quenching,the hardness of the rope groove at the weld is lower than that of the steel plate,which cannot fully meet the requirements of the drawing.As a result,the surface of the reel weld is worn more rapidly than that of the rope groove at other positions.
