进行平焊法兰的低温锻造时，锻件的尺寸变化会很小，在七百度以下的条件中进行锻造的话，所产生的锻造氧化皮很少而且表面不会产生脱碳的现象。因此，只要变形在成形的范围之内，冷锻很容易得到好的尺寸精度与表面光洁度高的平焊法兰。

Low temperature of flange forging, forging the size change will be very small, forging words in seven Baidu the following conditions, forging oxide generated very little and will not produce the phenomenon of surface decarburization. Therefore, as long as the deformation within the scope of the cold forging forming, it is easy to get good dimensional accuracy and surface finish of the flange.
