Product Description: Cast aluminum electric heating plates can be round, flat, right-angle, air-cooled, water-cooled, and other special shapes. After precision machining, they can be closely attached to the heated body. They are widely used in plastic machinery, mold heads, cable machinery, chemical, rubber, petroleum, and other equipment. Cast aluminum stainless steel electric heating plates have the advantages of long life, good thermal insulation, strong mechanical properties, corrosion resistance, and anti-magnetic field. The explosion-proof mark of cast aluminum explosion-proof heaters is ExdⅡBT4, ExDⅡBT6, ExdeⅡCT6, etc. They are widely used in plastic machinery, molds, cable machinery, alloy die-casting machines, pipelines, chemical, rubber, petroleum, and other equipment.
Precautions for Using Cast Aluminum Electric Heating Plates:
1. The working voltage of the cast aluminum heating plate must not exceed 10% of the rated value; the relative humidity of the air should not be greater than 95%, and there should be no explosive or corrosive gases.
2. The wiring part of the cast aluminum electric heating plate should be placed outside the heating layer and insulation layer, and the shell should be effectively grounded; avoid contact with corrosive, explosive media, and moisture; the lead wire should be able to withstand the temperature of the wiring part and the heating load for a long time, and avoid excessive force when tightening the wiring screws.
3. The cast aluminum electric heating plate should be stored in a dry place. If the insulation resistance is lower than 1MΩ due to long-term storage, it can be restored by baking in an oven at about 200°C for 5-6 hours, or by reducing the voltage and heating until the insulation resistance is restored.
4. The cast aluminum heating plate should be properly positioned and fixed, and the effective heating area must be closely attached to the heated body. Dry burning is strictly prohibited. If dust or contaminants are found on the surface, they should be cleaned promptly before reuse to avoid affecting heat dissipation and shortening the service life.
5. The magnesium oxide powder at the outlet end of the electric heating tube of the cast aluminum electric heating plate should be protected from contaminants and moisture in the use environment to prevent leakage accidents.
