某钢铁公司1700毫米连轧机组的卷板机系消化吸收国外同类设备制成的。这台设备在检修和技术改造前后,宝钢曾组织力量,协助进行振动测试与分析,来描述设备的技术状态,以便取得科学数据,判别改造后的实效。这是冶金系统首次将诊断技术实际应用到设备维修与技术改造中的实践,为今后应用诊断技术,开展预知维修工作提供了很好的经验。 一、测试前机组情况 1.卷筒及传动部分 卷筒为悬臂式无活动支承。卷筒旋转时由于卷取张力的影响,摆动较为严重;
A steel company 1700 mm rolling mill coil machine digestion and absorption of similar foreign equipment made. Before and after the overhaul and technical renovation of this equipment, Baosteel organized its efforts to carry out vibration testing and analysis to describe the technical status of the equipment in order to obtain scientific data and judge the actual effect after the renovation. This is the first time that the metallurgical system has applied the diagnostic technology to the practice of equipment maintenance and technical transformation for the first time, which provides a good experience for applying diagnostic technology and predicting maintenance work in the future. First, test the situation before the unit 1 reel and transmission part of the drum is not movable support cantilevered. When the reel rotates due to the influence of the winding tension, the swing is more serious;
