Protective layer treatment process and apparatus for reducing graphite electrode loss

The present invention discloses a treatment process and apparatus for the protective layer is reduced, and the graphite electrode by dipping and spraying processes combine the two methods, using a special means to achieve wet impregnation impregnation, and used together with good affinity with the graphite electrode paint components, these two methods can be realized by reducing graphite electrode consumption purposes. Advantages and effects of the present invention is further characterized by a mechanical treatment of the graphite electrodes immersed increase its porosity density is reduced based on the combination of high temperature oxidation of the graphite electrodes coating high temperature oxidation protection, the protective coating with improved graphite substrate compatibility and chemical compatibility, but also to avoid the heating process, by heating the graphite pores spillover gases may break continuous coating, a clear coating to ensure effective protection.
