What material is the heating plate of the belt vulcanizing machine

What is the material of the heating plate of the belt vulcanizing machine, in fact, the heating plate is made of ordinary carbon steel plate, the inside is hollowed out and an electric heating tube is added, the heating plate is to convert electrical energy into thermal energy and then heat the object, is a form of electrical energy . Compared with the general fuel heating, electric heating can obtain high temperature (temperature can reach more than 3000 ℃), easy to achieve automatic temperature control and remote control, vehicle electric heating cup can keep the heated object as needed Certain temperature distribution.
