本文根据三辊斜轧时的空间结构理论,阐明了 Transval 型轧机的两转角及三转角的转角轧制机理。并在辗轧变形区段喉径变化规律分析的基础上,建立了转角轧制时直径和壁厚变化的计算方法。
According to the spatial structure theory of three-roll oblique rolling, this paper clarifies the rolling mechanism of two-turn and three-turn rolling of the Transval-type rolling mill. Based on the analysis of the variation of the throat diameter in the rolling deformation zone, the calculation method of the variation of the diameter and the wall thickness in the corner rolling is established.
