正常情況下，銅板/銅帶表現不應該有劃傷，但是因為加工時不注意，運輸等原因造成的劃傷時有發生，銅板/銅帶表面如果有劃傷，那么對生產時就會造成一些麻煩，要進行一些處理才可以完成生產，那么表面如果劃傷，該如何處理呢？沈陽銅管廠家帶你來了解一下。

沈陽銅管廠家在(zai)這里講(jiang)一下簡單的處(chu)理(li)方式：如查銅(tong)(tong)(tong)板/銅(tong)(tong)(tong)帶(dai)表面有(you)輕微的劃(hua)傷(shang)，可用百潔布(bu)在(zai)劃(hua)傷(shang)部位進行來回擦(ca)試，進行打磨，可去除劃(hua)傷(shang)，如果銅(tong)(tong)(tong)板/銅(tong)(tong)(tong)帶(dai)表面劃(hua)傷(shang)較嚴重，銅(tong)(tong)(tong)板/銅(tong)(tong)(tong)帶(dai)在(zai)公(gong)差允許范圍(wei)內做拉絲處(chu)理(li)，銅(tong)(tong)(tong)板整體進行拉絲，打磨，去除劃(hua)傷(shang)。已達到(dao)表面光滑的作用。

沈陽銅管廠家認為正常情況半硬(ying)狀態下的(de)銅(tong)(tong)板(ban)/銅(tong)(tong)帶都(dou)應該有要(yao)求90度折彎不裂(lie)，而由生(sheng)產時(shi)，硬(ying)度值和延伸率(lv)沒有控制好，致(zhi)使銅(tong)(tong)板(ban)/銅(tong)(tong)帶在后(hou)續加(jia)工是折彎會裂(lie)，如生(sheng)產周(zhou)期較急，而不能換貨時(shi)，可采用在折彎時(shi)加(jia)熱，使銅(tong)(tong)板(ban)本(ben)身起到一些(xie)軟化，改變其狀態值的(de)作用，再進行折彎，可確保銅(tong)(tong)板(ban)/銅(tong)(tong)帶折彎時(shi)不裂(lie)。
