An Aluminum Coil Processing Technique

Aluminum coil is widely used in electronics, packaging, construction, machinery and so on. The production process of aluminum coil in our country has caught up with developed countries. Here is an aluminum coil processing technology.



In order to improve the structural performance of the aluminum coil, aluminum coil meet user requirements for product performance, production of aluminum coil annealing process, aluminum volume: 1, 2, rolling to the finished thickness; straightening and cleaning; 3, 4, the production of finished product annealing. When the aluminum coil is annealed, the aluminum coil will expand at high temperature, and the aluminum coil will come out from the inside out. Because of the different degree of heating and velocity, there will be a mutual dislocation between layers.
 
The invention performs spot welding at the end face of the aluminum coil between steps 2 and 3, and the number of aluminum rings welded by the spot welding phase is not less than two layers. The formation of the solder joint will be at least two aluminum ring welding layer adhered together, aluminum coil in annealing, the solder joint within the aluminum ring cannot interact the wrong layer, because the aluminum coil faults produce aluminum coil sticking defects phenomenon is also improved, in order to make the final aluminum coil quality is greatly improved.
