合金钢棒材生产线轧辊使用寿命的研究与应用

针对合金钢棒材生产线轧辊更换频繁，轧辊消耗量大的问题，分析得出轧辊表面龟裂、剥落、断辊和轧辊内部缺陷是影响轧辊使用寿命的重要因素。通过控制轧辊断裂技术的研究，提高孔型加工精度、改进轧辊切削工艺、改善轧辊冷却效果，通过对轧辊堆焊及修复技术的研究，提高轧辊的使用寿命，达到降低生产成本的目的。

RESEARCH AND APPLICATION OF ROLL SERVICE- LIFE IN ALLOY STEEL BAR PRODUCTION LINE

For problems of frequent roll change and serious roll consumption in alloy steel bar produc- tion line, analysis finds out that roll surface crack, roll surface peeling off, roll breakage, roll internal defects are important factors affecting the roll service life. Through technology research on controlling roll breakage, increasing the rolling pass machining accuracy, improving the roll cutting process and cooling effect, as well as study on roll bead welding and repairing technologies, the roll service life is increased and the purpose of reducing production cost is achieved.
