穿孔顶头辗轧段锥角的计算及合理设计

CALCULATION AND RATIONAL DESIGN OF PIERCING PLUG ROLLING TAPER

摘要: 根据穿孔时轧辊的布置特点,导出了空间变形区模型条件下的穿孔顶头辗轧段锥角的计算公式,比较了不同送进角时按照目前所采用的三种计算方法所计算的穿孔顶头辗乳段锥角的差异,给出了合理确定穿孔顶头辗轧段锥角的顶头位置参数。

Abstract: Bascd on the roll arrangement for piercing, the calculation formula for piercing plug rolling taper is deduced with a space deformation-zone model, Calculated with the three current calculation methods, different tapers due to different feeding angles are given, also the plug position parameters ensuring a rational taper.
