Causes of bonding in copper alloy strip processing
Causes of bonding in copper alloy strip processing?　　1. The surface of the strip is too rough.　　2. The coiling tension is too large, and the copper alloy plate and strip processed products are wound too tightly.　　3. The annealing temperature is too high or the holding time is too long.　　4. When the copper alloy strip is processed, the heating is not uniform during the heating process, and the amount of thermal expansion between layers is different.　　5. During the cooling process, the cooling speed is faster, which causes the shrinkage coefficient between the outer and inner coils to be different..　　If you want to avoid bonding in the processing of copper products.When coiling, especially before and after annealing, the tension should be moderate.Strictly control the heating and cooling speed when operating the annealing process.Appropriately reduce the annealing temperature or shorten the holding time.It is necessary to appropriately improve the smoothness of rolling.Consulting Hotline: 139-3883-7628.The content of the article comes from the copper alloy strip processing network: www.lygety.com/
