Φ375轧辊结构改进可行性研究

Feasibility Study of Structure Improvement of Φ375 Roll

轧辊结构改进,是通过轧辊承受多种应力分析,精确计算出外层镶套的加工过盈量,利用机械方式,将新套与旧辊芯二次组合成新辊,采用此法能节约1/2原材料投入,60%的辊颈循环利用,让废辊残值达到最大化;也是对轧辊修复技术的补充完善,适用于开槽成品辊,可最大限度挖掘出材料的优良性能。

Improvement of roll structure relies on the roll bearing a variety oi stress analysis and calculating accurately the interference magnitude of outer bushing, and adopts mechanical method to combine the new cover and old roll core to form the new roll. This way could save half of the raw material and utilize cycle roll neck of 60%, maximize the residual value of waste roll, complement the roll repairing technology. And this way is suitable for the slitting finished roll and could excavate excellent properties of materials maximally.
