The material composition line provides composition material to hot line for producing brazing sheet, which rolls together the silicon plate with aluminum ingot  and rotates as well.  During this process, the silicon plate and aluminum ingot are pinch welded in the middle and the ends.  Automatic belting are also used in the middle. 
Spec：Ingot: 5500x1450x(260~410)mm; Silicon plate: 5450x1400x(15~80)mm.
Components including five parts: feeding part, pinching part (for welding the ends together), rotation part (180 °), middle part belting,  unloading parts.
