摘要
分析了Y250轧机终轧六方钼杆存在的质量缺陷及对后续拉丝的不良影响。改进Y250轧机轧制孔型,并进行生产实践,确定圆钼杆的生产工艺。针对实际生产中φ7.4 mm圆钼杆的质量问题进行分析,提出改进措施,保证了轧制生产工艺的稳定,提高了圆钼杆的表面质量和后续拉丝的质量。
The quality defect of the molybdenum poles and its undesirable impact to the following wire-drawing procedure were analyzed.The rolling pass of Y250 rolling mill was improved and the production technique of the round molybdenum poles was determined.The quality problems of φ7.4 mm round molybdenum poles in practical production were analyzed and corrective measures were proposed.Thus,the stability of the rolling technique was guaranteed,the surfuce quality of the round molybdenum pole and the following wiredrawing quality were improved.
