What is the material of the heating plate of the belt vulcanizer? What is the material of the heating plate of the belt vulcanizer? In fact, the heating plate is made of ordinary carbon steel plate, which is hollowed out and added with an electric heating tube. The heating plate is a form of transforming electric energy into heat energy to heat objects. It is a form of electric energy utilization. Compared with general fuel heating, electric heating can obtain high temperature (the temperature can reach more than 3000 ℃), which is easy to realize automatic and remote control of temperature. The on-board electric heating cup can maintain the temperature distribution of the heated object as required.
