Key points of the new process:
On-line heat treatment of the material, without the need for the oven link in the old process. It can go into the stretching machine directly after laminating after casting.
Unwinding diameter:
In the new process, one unwind diameter is 1000mm (four layers), which can be 32 layers. The unwind diameter of the old process is only 550mm (four layers), and it can do 20 layers.
