Technical characteristics
Metal casting heater is a tubular electric heating element for heating, and bending forming, into the mold with high quality metal alloy material for the shell with a centrifugal cast into a variety of shapes, a round, flat, rectangular, air-cooled, water and other special-shaped. After finishing it is heated in close fitting, cast aluminum heater surface load can reach 2.5-4.5w/c square meters, maximum operating temperature 300-450 DEG C; cast copper heater surface load can reach 3.5-5.0w/c square meters, the maximum working temperature of 500-600 DEG C; cast iron heater surface load can be reached 4.5-6.0w/c square meters, maximum operating temperature 550-700 DEG C between. Metal casting heater is a kind of high efficiency and heat of the uniform of the heater, thermal conductivity of metal alloy, to ensure that the hot surface temperature uniformity, eliminating the hot and cold. With long life, good insulation performance, mechanical properties, corrosion resistance, anti magnetic field, etc.. The external heat dissipation surface to increase the insulation device, the internal heat radiating surface of the infrared ray can save electricity 35%.
