High Temperature Iron Cast Band Heaters - Reliable China Suppliers & Factory for Industrial Applications
Iron Cast Heater Characteristics
Cast iron coil heaters utilize a tubular heating element as the heating element, which is bent into shape. After entering the mold, the outer shell is made of high-quality metal alloy and centrifugally cast into various shapes, including round, flat, right-angle, air-cooled, water-cooled, and other special shapes. After precision machining, they adhere closely to the heated object.
| Material Type | Surface Load Range | Maximum Operating Temperature |
|---|---|---|
| Cast Aluminum Coils | 2.5 - 4.5 W/cm² | 300°C - 450°C |
| Cast Iron Coils (Type 1) | 3.5 - 5.0 W/cm² | 500°C - 600°C |
| Cast Iron Coils (Type 2) | 4.5 - 6.0 W/cm² | 550°C - 700°C |
Uniform Distribution
Metal cast coils offer high efficiency and uniform heat distribution. The metal alloy's excellent thermal conductivity ensures uniform heating surface temperature, eliminating hot and cold spots in the equipment.
Strong Durability
They offer key physical advantages such as long service life, excellent thermal insulation, strong mechanical properties, corrosion resistance, and magnetic field resistance.
Energy Saving Capability
Adding insulation to the outer heat dissipation surface and sintering the inner heat dissipation surface with infrared radiation can save up to 35% of electricity.
Frequently Asked Questions (FAQ)
What shapes are cast iron coil heaters available in?
They can be centrifugally cast into various shapes, including round, flat, right-angle, air-cooled, water-cooled, and other special shapes customized to match your equipment.
What is the maximum operating temperature of cast aluminum coils?
Cast aluminum coils offer a maximum operating temperature between 300°C and 450°C, with a surface load capacity of 2.5-4.5W/cm².
What temperature and surface load ranges do cast iron coils support?
Cast iron coils are available in two main ranges: one supporting a surface load of 3.5-5.0W/cm² (max temperature 500-600°C), and another supporting 4.5-6.0W/cm² (max temperature 550-700°C).
How do metal cast coils prevent hot and cold spots?
Thanks to the high-quality metal alloy's excellent thermal conductivity, the surface temperature remains completely uniform, which eliminates hot and cold spots during operation.
How can I achieve 35% electricity savings with these heaters?
You can save 35% of electricity by adding insulation to the outer heat dissipation surface and sintering the inner heat dissipation surface with infrared radiation.
