Electric heating elements, as one of common electric heating equipment, the biggest advantage is simple structure, low cost, applicable to a variety of object , heating. It has the advantanges of high mechanical strength, high thermal efficiency, with the protection of the outer metal shell and magnesia oxide, so the security is good, service life is longer than the other.
1. the structure of electric heating elements
Electric heating elements is a kind of electric heating equipment which is in simple structure, the outer layer is of the metal shell, material is stainless steel or copper. There is nickel chromium alloy ,iron chromium alloy wire, and the gap inside the mental tube is filled with Mgo powder, at last, Electric heating pipe tube is sealed by silicone.
2. the classification of the electric heating elements
it is used as electric heating components for different kinds of electric equipments ,it is classified by the usage. Common types mainly include air electric heating tube, liquid electric heat pipe, boiler electric heating tube, and oven with finned heating tube, sauna and steam rice machine electric heating tube etc.
3. the application of the electric heating tube
with the protection of the outer metal shell,Electric heat pipe is used for heating many objects, such as air, metal molds and liquid. Electric heating tube also can be used in industry such as tank, oil tank, acid and alkali tank, the fusible metal melting furnace, air heating furnace, drying furnace, drying oven, hot pressing molding device, etc.
