摘　　要：叙述了几种带槽轧辊的制造方法；铝合金环法克服了传统的分段冷型法工艺复杂、成本高、不能获得沿轧槽均匀分布的硬度的缺点；通过排出铝液的时间来控制带槽轧辊的性能，是制造大、中型带槽轧辊的一种先进方法。铸钢和半钢带槽轧辊降低了材料的消耗；This paper describes several manufacturing methods for the rollers with grooves.The chief shortcoming of traditional foundry processing of sectional chilling for roller is complex,high costed that can't provide evenly distributed hardness along the grooves .Aluminiumalloy ring method overcomes those shortcoming and the properties of the roller with grooves can be controlled by draining the liquid aluminiumalloy at different times.It is the better mehtod of making heavy and middle sized rollers.The steel and semisteel rollers with cast grooves decrease the expense of material.It may become a new method for manufacturing small sized Hialloy groovesd rollers .
