W type SiC heating elements

The structure of the three-phase silicon carbon rod is that the three heating bodies share a connecting bridge to connect the three-phase power supply to form a star connection, which is mainly used in the furnace for the production of float glass. Our three-phase rod uses the latest high-density HD type material, the density of the heating element is 2.65 g/CM3, and the resistance aging rate of the HD type heating element is much lower than that of the ordinary rod. In addition, a special coating treatment can be performed on the heating rod. The coating reacts with the alkaline atmosphere in the furnace at a high temperature to produce a dense glass protective film, which reduces the damage of the alkaline gas to the heating body, and thus further To extend the service life of the heating rod.
