Abstract

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.
