Continuous bright annealing furnace for copper foil is mainly composed of unwinder, heating furnace body, cooling water tank, guide roll shaping device, photoelectric rectifying device and winding device.

Under the control of micro tension control, the continuous bright annealing furnace for copper foil is discharged by the unwinder from the sealing part of the heating furnace body into the furnace, through the preheating section, heating section, heat preservation section and cooling section, and then winding at constant linear speed. As the copper foil is protected by carbon dioxide or nitrogen, the annealed product is soft, bright and non oxidized.

The continuous bright annealing furnace for copper foil is suitable for unfolding bright continuous annealing of precision pure copper strip, alloy copper strip, steel strip and stainless steel strip with thickness of 0.007 ~ 0.08mm and width of 100 ~ 600mm. The strip processed by the furnace is bright, spot free, consistent in physical properties, and has considerable production capacity, with a linear speed of 10 ~ 30m / min.
