介绍了预紧碟簧 (简称AIG)在轧钢厂分剪机上的应用 ,由于该设备螺栓预紧力的变化得到有效的补偿 ,从而解决了设备由于承受频繁的强烈冲击振动而导致无法正常生产的问题 The application of preloading disk spring (AIG) on the parting machine of steel rolling mill is introduced. Because of the prestressing force of the apparatus, the compensation is effectively compensated so as to solve the problem that the equipment can not be normally produced due to frequent strong shock and vibration problem
