After the continuous rolling mill rolls the steel coil, it enters the Steel Strip Processing Line for the following treatment:
1. Soaking in the alkaline washing tank: The steel coil first passes through the alkaline washing tank to remove the emulsion residue and preliminary impurities on the surface by soaking.
2. Electrolytic degreasing: Subsequently, the steel coil enters the electrolytic tank and uses electrodes for electrolysis to remove grease and other stubborn stains.
3. Brushing: After electrolytic degreasing, the steel coil passes through the brushing equipment, which uses a brush to remove surface residues to further ensure cleanliness.
4. Drying: Finally, the steel coil enters the drying stage to remove all moisture and prepare for the subsequent bell-type furnace annealing treatment.
After this series of Aluminum Strip Cleaning Line processes, the surface quality of the steel plate is significantly improved, effectively avoiding the problems of convection plate printing and steel plate bonding that may occur after bell-type furnace annealing.
