摘要
在大圆钢轧制或大断面轧件延伸孔型系统中,双半径椭圆孔型与单半径椭圆孔型相比,具有轧件易咬入、变形较均匀、孔型磨损小等优点。为此介绍了几种不同轧件断面尺寸情况下,双半径椭圆孔型的构成方法,并举出了5个不同厂家的应用实例,均取得较好效果。
The double radius ellipse pass is better than the one of single radius ellipse in the big round bar or big section steel rolling. It has some advantages, such as easy nipping, uniform deforming and small wearing of groove. The pass design methods of double radius ellipse for different section of piece are introduced. Its good usage effects in five factories are explained.
