The cast aluminum heater is a tubular heater with a heating element as a heating element. The electric heater is molded by a high-quality aluminum alloy material. The temperature is generally between 150 and 450 degrees Celsius. It can be widely used in plastic machinery and die. , cable machinery, chemicals, rubber, petroleum and other equipment.
The tubular heater that are normally cast or perforated in the cast aluminum heating plate are made of metal, and the main materials are iron, stainless steel, and imported materials.
1. Casting or punching in the cast aluminum heating plate requires metal heating tube, stainless steel heating tube and iron heating tube, and the surface is not charged.
2. If the surface of the heating wire is used, it will be charged.
3. The cast aluminum heating plate is normally used below 380 °C. For a long time above 400 degrees and even higher temperature, the aluminum plate will be deformed or even melted.
4, 304 stainless steel heating element surface temperature is about 450 degrees, can completely use the surface temperature uniformity of the cast aluminum heating plate and the tube arrangement, the flatness of the surface of the heating plate and the heating process of the heating tube are evenly related.
Precautions for the use of cast aluminum heating hot plate:
1. The operating voltage of the cast aluminum heating plate shall not exceed 10% of the rated value. The relative humidity of the air is not more than 95%, and there is no explosive or corrosive gas.
2, cast aluminum heating plate should be positioned and fixed, the effective heating zone must be closely attached to the heated body, prohibiting air burning.
3, should be placed in a dry place, if placed for a long time, the insulation resistance is less than 1MΩ, can be baked in an oven at 200 degrees Celsius for 5-6 hours, you can recover normal. Or reduce the voltage and heat it until the insulation resistance is recovered.
4. The wiring is placed outside the heating layer and the insulation layer. The outer casing should be effectively grounded; it should be protected from corrosive, explosive media and moisture. The lead wire should be able to accept some temperature and heating load for a long time. When the terminal screws are tightened. Should prevent excessive force.
