Water washing area of copper strip

After each copper block undergoes the initial rolling step, due to the presence of surface impurities, in order to avoid affecting the quality of the finished product, it must go through a sealing furnace again and then undergo a water washing program. The washing area is divided into two types of water tanks based on their acidity. The high concentration ranges from 6-8 degrees, while the low concentration ranges from 3-5 degrees. The medium red patches on the surface of the copper strip can be washed away by the acid solution in the water washing tank, while the dark red patches are removed by the iron fine bristles brushed during the washing period. After this series of treatment methods, the copper strip clearly shines with its inherent luster. If there are still red spots and red spots during the rolling process, a new washing step is still required. During the washing period, it is necessary to regularly check the acidity in the water tank and add acid in a timely manner to avoid insufficient washing due to low acid content
