摘　　要：生产球扁钢和 L 型钢的经济效益可达普通型钢的 10倍以上 ,并有相对固定的市场 ,但最大的障碍是多规格、小批量。规格不全难以占领市场 ;规格全 ,轧辊投入太大 ,企业不能承受。本研究是用一套轧辊生产 16～ 2 7号球扁钢 ,除 2～ 3个孔型外孔型系统共用 ,变规格时换孔不换辊。用半套轧辊生产所有规格的L 型钢 ,有一半轧槽与上述球扁钢共用。同样 ,用一套轧辊生产 16号以下的球扁钢。笔者在实验室进行了轧制模拟实验。The good economic benefits can be obtained from L section and bulb flats But the most difficult problem foe this kind of production is many specifications and small batch A new method to produce No 16 27 bulb flats with one set of rolls is used now at Laiwu Steel The passes on the same rolls are changed with over half of roll passes are common for both L section and bulb flats The simulated rolling has been carried out in the laboratory and good results were obtained The finishing pass design method and the deformation rules are discussed here
