  • Post-plating treatment (passivation, hot melting, sealing and hydrogen removal, etc.) for the purpose of enhancing protective properties, decoration and other special purposes. After galvanized, chromate passivation or other conversion treatment is generally required to form the corresponding type of conversion film, which is one of the key processes to ensure the quality of post-plating.

  • The hot plating wire uses zinc-free slag to add hot melt zinc and galvanize, which avoids the traditional heating process and radiates the surface 1653 of zinc liquid surface 4102 to the hot melt zinc, reducing the high temperature oxidation on the surface of zinc liquid. At the same time, the heating body is in contact with the zinc liquid, and the heat is directly transferred to the zinc liquid. The utilization rate of heat energy can reach more than 90%, which reduces the heat radiation of the zinc liquid surface.
