Cast aluminum electric heating plate

1.
Introduction
The cast aluminum electric heating plate uses a tubular electric heating element as the heating element. The element is bent and formed into a mold to cast aluminum into various products. It can closely fit the heated body, heat evenly, have good thermal conductivity, and have long service life. This product is currently one of the more ideal heaters at home and abroad. An insulation layer can be added to the outside of the heater according to user needs. Higher thermal efficiency can save electricity. Mainly used for heating plastic machinery, ovens, water boilers, pipes and non-corrosive liquids.
2. Main uses of cast aluminum electric heating plates
Widely used in plastic machinery, molds, cable machinery, alloy die-casting machines, pipelines, chemicals, rubber, petroleum and other equipment.
3. Technical characteristics of cast aluminum electric heating plate
It uses a tubular electric heating element as the heating element and is bent into shape. It enters the mold and uses high-quality metal alloy material as the shell to centrifugally cast it into various shapes, including round ones. , flat plate, right-angle, air-cooled, water-cooled and other special shapes, etc. After fine machining, it can fit closely with the heated object. The surface load of the cast aluminum electric heating plate can reach . The metal alloy with excellent conductivity ensures uniform temperature on the hot surface and eliminates hot and cold spots in the equipment. It has the advantages of long life, good thermal insulation performance, strong mechanical properties, corrosion resistance, and resistance to magnetic fields. Adding a thermal insulation device to the outer heat dissipation surface and sintering infrared rays on the inner heat dissipation surface can save electricity3.
4. Precautions for cast aluminum electric heating plates
The working voltage shall not exceed the rated value, the relative humidity of the air shall not exceed the rated value, and there shall be no explosive or corrosive gases.
The wiring part should be placed outside the heating layer and insulation layer. The shell should be effectively grounded to avoid contact with corrosive, explosive media and moisture. The lead wire should be able to withstand the temperature and heating load of the wiring part for a long time. When tightening the wiring screws Excessive force should be avoided.
The cast aluminum electric heating plate should be placed in a dry place. If the insulation resistance is lower than the insulation resistance due to long-term storage, it can be baked in an oven at a temperature of about 10 degrees Celsius for an hour, and it will return to normal. Or reduce the voltage and apply electricity until the insulation resistance is restored.
The cast aluminum electric heating plate should be well positioned and fixed, and the effective heating area must be in close contact with the heating body. Empty heating is strictly prohibited. When dust or contaminants are found on the surface, they should be cleaned in time before use to avoid affecting heat dissipation and shortening the service life.
The magnesium oxide powder at the outlet end of the cast aluminum electric heating plate prevents pollutants and moisture from penetrating into the place of use, and prevents leakage accidents.
