退火后线径变细：铜线在硬态时，出口模就是定径模，张力大小不至于把线径拉丝。
When annealed wire diameter necking: copper wire in hard state, export module is sizing die, tension size not the wire diameter wire drawing.
由实验证明胶丝挤出口模圆锥形通道比圆柱形通道能改善挤出条件，提高挤出质量。
The experiment has proved that mucilage at the extrude die with conicylindricalpassage is better than that with cylindrical passage in extruding condition and production.
一般连续退火出口模要选择比实际需要线径大0.0015—0.0035比较合适。
General continuous annealing export should choose to die than actual need wire diameter 0.0015-0.0035 more appropriate.
