It uses a tubular electric heating element as the heating element and bends it into shape. It enters the mold and uses high-quality metal alloy materials as the shell to centrifugally cast it into various shapes, including round, flat, right-angle, air-cooled, water-cooled and other special shapes. After finishing, it can fit closely with the heated body. The surface load can reach /, the surface load of cast copper can reach / between the maximum working temperature ℃, and the surface load of cast iron can reach /, the maximum working temperature can reach / between ℃. between ℃. The metal casting heater is a high-efficiency heater with uniform heat distribution. The metal alloy with excellent thermal conductivity ensures uniform temperature on the hot surface and eliminates hot and cold spots in the equipment. It has the advantages of long life, good thermal insulation performance, strong mechanical properties, corrosion resistance, and resistance to magnetic fields. Adding a thermal insulation device to the outer heat dissipation surface and sintering infrared rays on the inner heat dissipation surface can save electricity. 2. Main uses
Widely used in plastic machinery, molds, cable machinery, alloy die-casting machines, pipelines, chemicals, rubber, petroleum and other equipment.
3. Precautions for use
The working voltage shall not exceed the rated value, the relative humidity of the air shall not exceed the rated value, and there shall be no explosive or corrosive gases.
The wiring part should be placed outside the heating layer and insulation layer. The shell should be effectively grounded to avoid contact with corrosive, explosive media and moisture. The lead wire should be able to withstand the temperature and heating load of the wiring part for a long time. When tightening the wiring screws Excessive force should be avoided.
The metal casting heater should be placed in a dry place. If the insulation resistance is lower than the insulation resistance due to long-term storage, it can be baked in an oven at about 100 degrees Celsius for an hour to return to normal. Or reduce the voltage and apply electricity until the insulation resistance is restored.
. Metal casting heaters should be well positioned and fixed. The effective heating area must be in close contact with the heating body. Empty heating is strictly prohibited.
