High Temperature Iron Cast Band Heater from China Suppliers - Reliable Factory for Industrial Heating Solutions
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.
Surface Load: 2.5 - 4.5 W/cm²
Max Operating Temp: 300 - 450°C
Surface Load: 3.5 - 5.0 W/cm²
Max Operating Temp: 500 - 600°C
Surface Load: 4.5 - 6.0 W/cm²
Max Operating Temp: 550 - 700°C
Metal cast coils offer high efficiency. The metal alloy's excellent thermal conductivity ensures uniform heating surface temperature, eliminating hot and cold spots in the equipment.
They offer key advantages such as long operational life, excellent thermal insulation, robust mechanical properties, corrosion resistance, and magnetic field resistance.
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.
