This furnace is suitable for continuous galvanizing treatment of hard and flexible wires. Neu-Sanken has the technology of all-electrical non-polluting exhaust pickling bath. Besides,with the immersion tube internal heat exchanging burner, the consumption is decreased greatly. Neu-Sanken could provide the ceramic bath for treating the Zn and ZN-AI.Compared with the traditional ferrous bath, the life of ceramic is longer,no need to periodic replacement,the maintenance cost is low. At the same time,it avoids the raw material loss suring ferrous bath replacement,greatly decrease the loss which caused by leaking emergency stop.
