冷硬铸铁轧辊的机加工工艺研究 马 辉 (邢台职业技术学院机电系, 河北邢台 054035) : 冷硬铸铁轧辊辊身硬度高, 耐磨性好,被广泛用于板材线材和棒材轧机上,但同时, 它也存 难以被切削加工的问题, 本文探讨了冷硬铸铁轧辊的切削性能, 分析了冷硬铸铁轧辊切削加工困难的 原因, 对冷硬铸铁轧辊切削加工工艺进行了改进, 提高了切削加工的质量,并且减少了切削加工的时间 :铸铁轧辊; 切削加工; 刀具 : TG 3 : A R esearch of M ach ining Processes on the Ch illed C ast Iron Roll MA Hui (Electrical andM echanicalDepartment, X ingtai ocational and TechnicalCollege, X ingtai054035, China) A bstract: The chilled cast iron roll is widely used in the plate, wire and bar m ills, because of the advantages such as high hardness and good abrasion resistance. However, the chilled cast iron roll is also difficult to cutting form ing for its high hardness on its surface. The paper discusses the cutting characteristic of chilled cast iron roll, and analyses the cause of difficultmachining. By mi proving the cutting process technology of the chilled cast iron rol,l it can increase the cutting quality of the chilled cast iron roll and cut down the cutting cost.
