Description

Technical Field

[0001] This utility model relates to the field of copper plate strip surface oxidation defect removal device. Background Technology

[0002] Copper strip is a plate-shaped copper structure formed by die casting of copper raw materials. It has excellent electrical conductivity and is often used in the interior of various power devices.

[0003] During the production of copper strip, the raw copper material is often fired at high temperature and then die-cast. After the high-temperature firing is completed, the surface of the copper block to be die-cast will have oxidation defects due to oxidation. If these defects are not removed, they will be pressed into the interior of the copper strip, thus affecting the quality of the copper strip.

[0004] The commonly used method is to spray the copper strip surface with a descaling device. However, after removing the surface oxidation, this method often leaves water film, phosphorus washing liquid or debris and other stains on the surface, which will still affect the subsequent die casting process.
