Abstract

The invention provides a heating pipe surface enamel dry firing process. The surface of a heating pipe is subjected to enamel dry firing processing through the process steps of washing, drying, enamel soaking, baking, sintering and attached glaze washing. An electric heater is optimized in the enamel process, only the enamel needs to be changed into the dry firing electrification process, the problems of a cold area, scaling and corrosion of a pipe body and the like during working of the heating pipe in water for a long time can be solved effectively, and the service life of products is prolonged.

Description

technical field [0001] The invention relates to the field of surface treatment of heating tubes, in particular to a process of dry firing enamel on the surface of heating tubes. Background technique [0002] At present, electric water heaters have been widely used in daily life due to their advantages of fast heating, convenient installation, and simple use. However, problems such as scaling, corrosion, and rust of electric heaters are common. At present, the traditional electroplating process directly uses anti-corrosion materials Scaling is inevitable. Although the high-temperature enamel of the tunnel furnace can solve the problem of scaling, no enamel part (the cold end part of the heating element) will be oxidized during the high-temperature enamel process of the tunnel furnace, so it is easy to rust when working in water for a long time. Seriously affect the service life and safety of the product. Now using the energized dry-fired enamel process can avoid scaling, corr...
