Multiple slip type wet-drawing process

摘要

In a multiple slip type wet-drawing process using plural drawing pass stages each comprised of a die (1) and a capstan (2) drawing a wire rod (3) passed through the die, an average slip rate in each drawing pass stage other than a final stage is set to a range of 5 - 80 m/min, whereby the wire drawing may be carried out without causing problems such as damage of wire rod surface, wire breakage, premature wearing of die and the like.
