Problems solved by technology
[0002] In the production line of plastic composite pipe with steel mesh skeleton, the outer layer of the core pipe is wound with steel wire and before entering the rubber mold, in order to make the surface of the core pipe reach the expected temperature, it is usually necessary to heat the surface of the core pipe. In the prior art, people usually use ceramic heating. The device heats the surface of the core tube, that is, a ceramic heating block is set inside the oven, and an electric heating wire is arranged in the ceramic heating block, and the ceramic block is heated by energizing the electric heating wire, and then the heat is transferred to the core tube. After long-term use of the ceramic heating device or when the power is too large, the ceramic heating block inside the oven is easy to burn out, affecting normal production
