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.
但是在连续退火时，铜线发热使线材变软，线本身就有一定的延伸。
But in the continuous annealing, copper wire heating make wire become soft, line itself has certain extension.
在现场操作中，会造成退火后线径变细、表面划伤、铜线发红、铜线变色、铜线氧化等一些现象。
In the field operation, can cause annealed wire diameter necked, surface scratch, red copper wire, copper wire color, copper wire oxidation and so on some phenomenon.
铜线变色(暗红或发白)：连续退火在工作段把线烧软，还要经过冷却段冷却后才能达到引出线不烫、不带水。
Copper wire color (dark red or white) : continuous annealing in the work period of the line burn soft and pass cooling section after cooling can achieve lead not hot, without water.
连续退火(交流)大拉机使用盘式收线生产时，大规格铜线有时性能不稳定。
Large size copper wires produced by continuous annealing AC bull block using disk type take up sometimes show unstable performance.
三角结构的外层导电铜轮分内外两沟，铜线经内沟引入，完成退火。
Triangular structure of the outer conductive copper wheel points inside and outside two groove, the copper wire inside groove introduced, complete annealing.
铜线退火后发红：连续退火分三个段：预热段，工作段、冷却段。
After annealing copper red: continuous annealing three sections: preheating section, the work piece, cooling section.
铜线退火后发红：连续退火分三个段：预热段，工作段、冷却段。
After annealing copper red: continuous annealing three sections: preheating section, the work piece, cooling section.
