摘　　要：本文探讨了平辊轧制方形坯或矩形坯的可能性,研究了高宽比对轧件脱方率的影响,压下率对轧件侧边鼓形率的影响,临界压下率和轧制几何参数的关系,宽展量的统计公式,导板间隙系数对轧件稳定性的影响,并得出了相应的结论。In this paper,following topics during bar rolling with flat rolls are discussed:(1) possibi-lity of rolling square or rectangular bar;(2) affect of height to width ratio on the off-squarerate;(3) affect of reduction in height on the free side-bulge rate;(4) relationship between thecritical reduction in height and the rolling geometrical parameters;(5) effect of gap coefficientbetween two guides on the bar stability and regression equation of spread.Some correspondingconclusions have been obtained.
