High Quality High temperature Melting/ heating furance for LPG cylinder
Product Description
After a period of use, the paint on the surface of the cylinder will peel and peel off, thus causing the surface of the cylinder to rust and corrode. After the expiration of use, the surface of the cylinder must be thoroughly cleaned and repainted at the same time as the inspection. At present, due to the use of electrostatic spraying technology, the firmness of the paint film has been further improved, and some paint films are difficult to remove by shot blasting. In order to completely remove the paint film on the steel cylinder, only through the heat treatment furnace, the paint film on the surface of the steel cylinder is burned into charcoal or ashes. This makes it easy to remove any remaining paint from the surface, creating good conditions for blast cleaning and repainting.
