退火是影响铜盘管内表面清洁度质量特性的关键工序之一,内吹扫是退火工序提高铜盘管清洁度的支配性工序要素。本文着重研究钟罩炉内吹扫(排气、冷吹和热吹)三种方式。结果证明,热吹是一种最佳的内吹扫方式。
Annealing is one of the key processes that affect the quality characteristics of the surface cleanliness of copper coils. Internal purging is the dominant process step in the annealing process to improve the cleanliness of copper coils. This article focuses on the bell furnace blasting (exhaust, cold blow and hot blow) three ways. The results show that hot air blowing is the best way of internal purge.
