type of band heater
Band heaters, that is, ring-shaped electric heater. And sometimes can be made of plate, that is, electric panels, but the shape of different, essentially the same. In general, the electric lap in accordance with the material, the production process can be divided into two categories: stainless steel band heaters and casting class band heaters.

Stainless steel band heaters
Stainless steel ceramic band heaters
High-temperature ceramic band heater is not used in the production of general mica flex line, but the use of ceramic wear wire way, so the power of the product than ordinary 0.5 to 1.5 times higher. The heating element is made of imported stainless steel and the outer cover is made of Japanese stainless steel. The middle temperature insulation cotton (aluminum silicate fiber board) is used to prevent the temperature from leaking. Ceramic is a high-frequency ceramic heat transfer fast, hard non-friable, high temperature deformation is not easy to aging and so on.
Ceramic band heaters Brief performance: It is mainly applied to the extrusion, casting and undershoot mechanical operation temperature can reach 450 degrees, the maximum surface load of 6.5W / cm. Is characterized by long life and high temperature, energy consumption reduced by 30%, high insulation , Is the extruder, injection molding machine, blown film machine most suitable for electric heating products.
Ceramic band heaters have the advantages of easy installation, fast heat transfer and good insulation, and are not limited by size and size. High working temperature, fast heating, high thermal efficiency, no pollution, uniform heating and accurate. Specific advantages are as follows:
1, with a winding, such as heating containers or pipes, can be bent into an arc or circular cladding in the surface heating, such as heating large parts, the local recoverable package complex form, a large area of the workpiece can be tiled cover form. In addition, it is suitable for the heating of various geometric shapes.
2, the working temperature is high, heating up fast, high thermal efficiency, pollution-free, uniform heating accurate, can achieve automatic control.
3, high mechanical strength, thermal insulation properties, and the heated object contact surface, long service life.
4, installation, easy maintenance, the use of low cost, even if the internal heating material damage, while the external ceramic devices can still be reused.
