What is the application and advantages of cast aluminum heater plate ‌‌?

First, the production of cast-in aluminum heating plate

Casting aluminum heating plate can be divided into die casting and casting , in the case of more specifications and sizes, the casting process is generally used. In the casting production, high-purity aluminum blocks are used, which are changed from solid to liquid by a high-temperature furnace, and then injected into a mold that has been installed with a heating tube, and after cooling and forming, it is made of fine processing.

The normal thickness of the cast aluminum heating plate is 20m and 25mm, of which the inner wall of the heating ring with a wall thickness of 25m is designed with a concave and convex wind trough structure, in order to prevent the temperature of the internal heating tube from being too high in use, for example, when the temperature is high, the inner wall can be cooled by wind or water, so that it can quickly reach the standard temperature. At the same time, the heating ring is basically divided into two semicircular circles, and then fixed and installed by fixing bolts.

Second, the use of cast aluminum heater plate precautions

1, the working voltage of the aluminum heating plate ​shall not exceed 10% of the rated value; The relative humidity of the air is not more than 95%, no explosive and corrosive gases.

2, the wiring part is placed outside the heating layer and insulation layer, and the shell should be effectively grounded; Avoid contact with corrosive, explosive media, moisture; The wiring should be able to withstand the temperature and heating load of the wiring part for a long time, and the fastening of the wiring screws should avoid excessive force.

3, the cast aluminum heat plate should be placed in a dry place, if the insulation resistance is lower than 1MQ due to long-term placement, it can be baked in the oven at about 200 degrees Celsius for 5-6 hours, you can return to normal. Or reduce the voltage and power heating until the insulation resistance is restored.

4, the cast aluminum heat press plate should be positioned and fixed, the effective heating area must be closely fitted with the heated body, and air burning is strictly prohibited. When the table is found to have dust or pollutants, it should be cleaned and used again in time to avoid the shadow and heat dissipation and shorten the service life.

5. The magnesium oxide powder at the outlet end of the electric heat pipe of the cast aluminum heater can avoid the infiltration of pollutants and water in the use place to prevent the occurrence of leakage accidents.

Aluminum alloy cast aluminum heating plate, the heating ring is a tubular electric heating element as the heating body, the element is bent and formed into the mold, after casting aluminum into a variety of products, there are heating ring, air cooled heating ring (inside and outside with air trough) water cooled heating ring (with water pipe), plate, right Angle plate and other varieties.
