KOCKS轧机成品波浪弯曲分析及改善

Analysis and Improvement on Wave Bending of Finished Products with KOCKS Rolling Mill

通过对KOCKS轧机轧辊辊环与法兰盘的相对运动、机芯经过CAPAS系统检测分级和C模块传动轴振动检测规律进行分析,探讨轧机设备故障对产品质量的影响及改进措施。结果表明,规格Φ19 mm以上棒材弯曲为轧机工况恶化产生,对轧机轴套、法兰盘进行维护可以有效改善成品波浪弯;规格Φ19 mm以下棒材弯曲为轧机振动产生,通过对轧机机芯、传动系统维修可以明显改善成品弯曲,传动轴滚动轴承强度决定了轧辊轴向窜动,影响轧机震动,使用高质量滚动轴可承明显改善成品轧材波浪弯曲。

In this paper,the influences of equipment failure for rolling mill on product quality and improvement measures are discussed by analyzing the relative movement of roll collar for KOCKS rolling mill and flange plate,detection and classification of movement through CAPAS system as well as vibration detection rules of transmission shaft for C module.The results showed that the bending of bars aboveΦ19 mm was caused by the deterioration of working condition for rolling mill as well as the wave bending of finished product could be effectively improved through maintaining the shaft sleeve and flange plate of rolling mill;the bending of bars belowΦ19 mm was caused by the vibration of rolling mill as well as the wave bending of finished product could be obviously improved through repairing the movement and drive system of rolling mill.The axial drifting of roller is determined by strength of rolling bearing of drive shaft so that the vibration of rolling mill is affected.As a result,the wave bending of finished products could be obviously improved through using high quality rolling bearing.
