1. Technical characteristics of cast copper heater:
The metal casting heater is a tubular electric heating element as the heating body, which is bent and formed. The high{{0}}quality metal alloy material is used as the shell to enter the mold. Alien, etc. After finishing, it can be closely attached to the heated body, the surface load of the cast aluminum heater can reach 2.5-4.5w/cm2, the maximum working temperature is between 300-450 degree ; the surface load of the cast copper heater can reach 3.5-5.0 w/cm2, the maximum working temperature is between 500-600 degree ; the surface load of the cast iron heater can reach 4.5-6.0w/cm2, and the maximum working temperature is between 550-700 degree . The metal casting heater is a kind of high-efficiency heater with uniform heat distribution. The metal alloy with excellent thermal conductivity ensures the uniform temperature of the hot surface and eliminates the hot and cold spots of the equipment. It has the advantages of long life, good thermal insulation performance, strong mechanical performance, corrosion resistance and magnetic field resistance. Adding a heat preservation device to the outer heat dissipation surface and sintering infrared rays on the inner heat dissipation surface can save electricity by 35 percent .
Second, the main purpose:
Widely used in plastic machinery, molds, cable machinery, alloy die-casting machines, pipelines, chemicals, rubber, petroleum and other equipment.
3. Precautions for use:
1. The working voltage shall not exceed 10 percent of the rated value; the relative humidity of the air shall not exceed 95 percent , and there shall be no explosive and corrosive gases.
2. The wiring part is placed outside the heating layer and the thermal insulation layer, and the shell should be effectively grounded; 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, and the wiring screws should be tightened. Avoid using too much force.
3. The metal casting heater should be placed in a dry place. If the insulation resistance is lower than 1MΩ due to long-term storage, it can be baked in an oven at about 200 degrees Celsius for 5-6 hours, and it can return to normal. Or reduce the voltage and energize until the insulation resistance is restored.
4. The metal casting heater should be well positioned and fixed, and the effective heating area must be closely attached to the heating body, and empty burning is strictly prohibited. When dust or pollutants are found on the surface, it should be cleaned and reused in time to avoid affecting the heat dissipation and shortening the service life.
5. The magnesium oxide powder at the outlet end of the electric heating tube can avoid the infiltration of pollutants and moisture in the use site, and prevent the occurrence of electric leakage accidents.
