Generally, when the stainless steel plate electric heating tube is used for heating, the heat is transferred from the heating wire route to the magnesium oxide powder powder, and then the magnesium oxide powder is used to heat the wall thickness of the stainless steel plate. In the whole process, the heating capacity of the heating wire has been consumed a lot, so it is very difficult to use it Generally, the heating temperature of metal electric heating tube is relatively low.
The purpose of porcelain electric heating tube is to conduct heat from the heating wire to the ceramic tube immediately, which can immediately heat the mold steel, greatly reducing the heating time of the mold shell. In addition, the electric heating tube made of alumina ceramic material not only reduces the heating time of mold shell, but also has higher power. In addition, the die shell loss rate is reduced by 90%, and the service life of the electric heating tube is improved. The electric heating material of the electric heating tube is located in the groove of the trough plate, which is also called the inner tank of the instant electric water heater. The electric heating tube made of metal material is selected as the heating body of the instant electric water heater. When the cold water enters the inner tank, it immediately flows through the surface of the stainless steel plate heating tube and is heated. The stainless steel plate electric heating tube is one of the most widely used parts in the field of instant domestic water heater at present There is a heating method.
