First, cast aluminum heater main purposes: widely used in plastics machinery, molds, cable machinery, alloy die-casting machines, pipelines, chemical, rubber, oil and other equipment. Second, the technical characteristics: cast aluminum heater is a tubular heating element for heating element, and bent shape, into the mold with high quality metal alloy material for the shell to centrifugal casting into a variety of shapes, there are round, flat, rectangular type, wind cold, water, and other special-shaped and so on. After finishing it can be heated and close fitting, cast aluminum heater surface load can reach 2.5-4.5w / cm2, the maximum operating temperature between 300-450 ℃; copper heater surface load up to 3.5-5.0 w / cm2, the maximum operating temperature between 500-600 ℃; cast iron heater surface load can reach 4.5-6.0w / cm2, the maximum operating temperature between 550-700 ℃. Metal casting is an efficient heat heater heater division uniform, excellent thermal conductivity metal alloy, ensuring hot surface temperature uniformity, eliminating hot and cold spots of the device. With a long life, good insulation properties, high mechanical properties, corrosion resistance, magnetic field and so on. The outer surface to increase heat insulation device, within the thermal infrared surface sintering This can save electricity by 35%. Third, the use of note: 1, the working voltage rating not exceeding 10%; relative humidity less than 95%, non-explosive and corrosive gases. 2, the wiring part on the heating layer, insulation layer outside the shell should be effectively grounded; avoid corrosive, explosive material, in contact with water; lead wire should be able to withstand long-term temperature and heating load wiring part, terminal screws should be tightened Avoid excessive force. 3, cast aluminum heater should be stored in a dry place, if the issues long-term placement, insulation resistance is less than 1MΩ, 5-6 hours can be baked in an oven at 200 degrees Celsius or so, and can be restored to normal. Or lower voltage ohmic heating, insulation resistance until recovery. 4, cast aluminum heater should be prepared to locate fixed, effective heating area must fit closely with the heated body, air burning is prohibited. Found surface dust or contaminants should be cleaned and then, in order to avoid IMPACT heat and shorten life. 5, electric tube outlet end of magnesium oxide powder, in the use of premises to avoid contamination by water infiltration and prevent leakage accidents.
