The thermal inertia ceramic heating element is a kind of heating element that is a solid block by pressing an electric heating element and a ceramic material and then sintering at a high temperature. It first heats the magnesia brick through the electric heating element, and the maximum heat storage is 550-600℃. The internal heat source is evenly heated, and the ceramic plate heats up evenly as a whole, and has a good heat storage capacity, which can maintain a certain inertial output and continue to provide heat.
