摘要
简述了现有“平出”和“立出”平椭圆孔型存在的缺陷, 指出斜置平椭圆孔型可扬长避短, 尤其在控制焊缝位置、延长轧辊使用寿命及操作调试等方面优点明显。提出了不具体分配整形余量、直接用公称长度设计孔型长度、按宽高比决定斜置角度等有新意的设计原则, 并举例进行设计。目前已有多套斜置平椭圆轧辊投入生产, 优点显著。
The existed defects of flat ellipse pass with present “horizontal out” and “vertical out” is explained and the advantage of tilt installed flat ellipse pass,especially the distinct strong point in controlling weld seam position,prolonging the usage life of rollers as well as operating and commissioning,etc..is indicated. The new design principles of unspecific assign plastic allowance,design pass length with nominal length directly and decide tilt installed angles according to ratio of width and highness etc..is raised with design of example. Now there are many sets tilt installed flat ellipse rollers putting into production with prominence strongpoint.
