Annealing and soft silk 退火黑软丝
Because after annealing line is very soft, corresponding to different wire diameter to use appropriate tension weight, if wire diameter small tension is big, will be the wire diameter and thin.
因为退火后的线已经很软了，对应不同的的线径要采用合适的张力重量，如果线径小张力大，就会把线径拉细了。
But in the continuous annealing, copper wire heating make wire become soft, line itself has certain extension.
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。
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.
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。
