Hot Stamp and Die Heating
Heater elements within electric heaters are mainly composed of three elements: an insulating core, a heat conductive coil wrapped around the insulation, and an encasing sheath made from stainless steel, aluminum, nickel or iron.
Insulating cores are necessary for most types of electric heaters to retain and absorb electrical energy so that it might be released as heat energy by surrounding coils or materials.
However, coiled wire heater elements, such as those used as household dryer heating elements, have no insulating core but transfer heat directly to the air through blown convection.
In higher heat applications, cores are responsible for converting electrical energy into heat energy and are heating elements' major component. Heater element cores are generally made from either NiChrome, a high resistance 80% nickel 20% chromium compound, or from a Positive Thermal Coefficient ceramic, which is a highly heat resistant barium titanate/lead titanate composite. Ceramics and NiChrome are by far the most common insulation materials, although various heater elements may use mineral insulation such as magnesium oxide, mica or fiberglass, depending on the heater's application requirements.
Process of Cast Aluminum Heater
Installation:
1.Allow sufficient space for thermal expansion. The amount of space required depends upon the Cast-In Heater size and operating temperatures.
2.Surface being heated must be free of any foreign materials and have a smooth finish.
3.Make sure that the casting is properly seated. The clamping devices used should be tightened down as much as possible.
4.After initial heat-up, retighten clamping devices to assure good surface contact.
5.Thermal insulation can be used to reduce heat losses, providing insulation does not come in contact with heaters.
6.Avoid mounting heaters in an atmosphere containing combustible gases and vapors.
7.On Cast-In Heaters equipped with water cool jackets, fittings must be securely tightened due to the high concentration of steam pressure buildup inside the cooling jacket. Flare type or braze seal fittings are recommended over compression type fittings.
8.To prevent overheating and heater failure, adequate temperature controls should be installed.
Wiring:
1.For connections at the heater terminals, use high temperature nickel conductor lead wire or alloy bus bar. Keep all electrical connections properly protected to eliminate electric shock to machine operators.
2.Heaters of equal wattage and voltage can be series connected for next higher voltage.
3.Heater installations must be properly grounded to eliminate electric shock hazard, and wiring must comply with electrical codes.
4.Always have a qualified electrician perform all wiring and connection of heaters and control components.
How to Maintain Cast Aluminum Heater
Never perform any type of service on heaters prior to disconnecting all electrical power.
To assure good surface contact, periodically check clamping system.
Repeat cycling of temperature controls can indicate poor surface contact or a burned-out heater.
Heater terminals must be kept free of plastics, oil, water, and any other foreign matter. As these materials carbonize, they create electrical shorts.
Heater terminal electrical connections must be kept tight. Loose connections can overheat and eventually destroy the connection or the heater terminal.
Water lines must be periodically checked for leaks. Water on heater terminals can be detrimental to the entire heating system.
Thermocouples must be kept free of contaminants and be checked for good response to temperature changes. Our recommendation is to change them periodically as a bad thermocouple can be the cause of destroying an entire heating zone.
How Do Cast Aluminum Heater Work
The Aluminium Cast Heater works at the basic science of energy switch; turning electrical strength into sizable heat electricity. The built-in electrical resistance cord within the heater transforms the incoming electric contemporary into warmness. As aluminium alloy possesses high-quality thermal conductivity, the heat generated by way of the coil swiftly disperses throughout the surface of the heater, imposing uniform warmth distribution. To mild the amount and concentration of warmth, aluminium cast warmers are geared up with included thermocouples and RTD sensors. These devices reveal the temperature continuously and produce feedback for warmth manipulate units, maintaining temperature accuracy and stopping overheating.
