Introduction;
Heating ring, Explosion-proof High Temperature Ceramic Heating Ring is an electric heater made of resistance wire as heating element and high-quality ceramic material as shell, connected in series. Its operating temperature is generally between 250 and 550 degrees Celsius. The ceramic heating ring has the advantages of long life, good insulation performance, strong mechanical properties, corrosion resistance, and anti-magnetic field. It is widely used in plastic machinery, molds, cable machinery, alloy die-casting machines, pipelines, chemical industry, rubber, petroleum and other equipment.
Technical Details;
Explosion-proof Ceramic Heating Ring uses resistance wire as heating element, connected in series, and then enters the mold with high-quality metal alloy material as shell to be die-cast into various shapes, including round, flat, right-angle, air-cooled, water-cooled and other special shapes. After precision processing, it can closely fit the heated body.
Ceramic heating ring surface load can reach 4.5-6.5w/cm2, maximum working temperature between 400-550℃;
Ceramic manufactured heater is a high-efficiency heater with uniform heat distribution. The metal alloy with excellent thermal conductivity ensures uniform hot surface temperature, eliminating hot spots and cold spots of the equipment. It has the advantages of long life, good thermal insulation performance, strong mechanical properties, corrosion resistance, and anti-magnetic field. Adding insulation device on the outer heat dissipation surface and sintering infrared on the inner heat dissipation surface can save electricity by 35%.
Precautions;
Explosion-proof Ceramic Heating Ring working voltage shall not exceed 10% of the rated value; relative air humidity not greater than 95%, no explosive and corrosive gases.
The wiring part should be placed outside the heating layer and 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 of the wiring part and the heating load for a long time, and avoid excessive force when tightening the wiring screws.
Metal casting heater should be stored 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 to restore normal. Or reduce the voltage and energize to heat until the insulation resistance is restored.
Metal casting heater should be properly positioned and fixed, the effective heating area must be closely attached to the heated body, and dry burning is strictly prohibited. If dust or contaminants are found on the surface, clean them promptly before reuse to avoid affecting heat dissipation and shortening service life.
