论空拔均壁作用的条件性

CONDITIONALITY OF WALL-UNIFORM IN EMPTY SINKING

本文研究了空拔均壁作用的条件性。研究结果表明,空拔的均壁作用是有条件的。空拔后钢管的弯曲度越大,均壁作用越小,甚至加剧壁厚不均。

The conditionality of wall-uniform effect in empty sinking was studied and the result shows that the effect of wall-unlform in empty sinking must be on some conditions. The greater the tube-flexure after drawing is, the worse the wall-uniform effect and even the non-uniformity of wall thickness is aggravated.
