满足铝合金超常铸轧工艺所需综合技术性能要求的辊套材料,是采用双辊连续铸轧方法实现铝合金超常铸轧的重要技术保障．辊套材料良好的切削加工性能是获得高性能铸轧辊的基础．对新型铸轧辊套材料的切削加工性能进行了综合分析;从切削力和已加工表面粗糙度两方面,对新型铸轧辊套材料的切削加工性能进行了实验研究．结果表明,新型铝合金超常铸轧辊套材料具有优良的切削加工性能;在相同的加工条件下,切削新型辊套材料时的切削力明显小于切削现有典型合金钢辊套材料,磨削新型辊套材料时的表面粗糙度值与磨削合金钢辊套材料无明显差别．图4,表4,参12．
The material of roll cover that meets the comprehensive technical performance requirements of the extraordinary casting and rolling process of aluminum alloy is an important technical guarantee for the super casting and rolling of the aluminum alloy by the two-roll continuous casting and rolling method. The good machinability of the sleeve material is the basis for high-performance casting rolls. The cutting performance of the new roll shell material is analyzed comprehensively. The cutting performance of the new roll shell material is studied from the aspects of cutting force and machined surface roughness. The results show that the new aluminum alloy super-cast roll cover material has excellent machinability. Under the same processing conditions, the cutting force when cutting the new material is obviously less than that of cutting the existing typical alloy steel sleeve material, The surface roughness of the sleeve material and grinding alloy steel sleeve material no significant difference.
