Introduction;
Heating Ring, Explosion-Proof High-Temperature Ceramic Heating Ring is an electric heater formed by connecting resistance wire heating elements in series, with high-quality ceramic material as the outer shell. Its operating temperature is generally between 250 and 550 degrees Celsius. The ceramic heating ring features long service life, good insulation performance, strong mechanical properties, corrosion resistance, and magnetic field resistance. It is widely used in plastic machinery, molds, cable machinery, alloy die-casting machines, pipelines, chemical industry, rubber, petroleum, and other equipment.
Heating Ring, Explosion-Proof High-Temperature Ceramic Heating RingTechnical Features:
The ceramic heating ring uses resistance wire heating elements as the heating body, connected in series, and then enters a mold with high-quality metal alloy material as the outer shell to be die-cast into various shapes, including round, flat, right-angle, air-cooled, water-cooled, and other special shapes. After precision machining, it can closely fit the heated object.
Ceramic heating ring surface load can reach4.5-6.5w/cm2, maximum working temperature400-550℃;
Ceramicmanufactured heater is an efficient heater with uniform heat distribution. The metal alloy with excellent thermal conductivity ensures uniform hot surface temperature, eliminating hot and cold spots on the equipment. It has advantages such as long life, good thermal insulation, strong mechanical properties, corrosion resistance, and magnetic field resistance. Adding insulation device on the outer heat dissipation surface and sintering infrared on the inner heat dissipation surface can save electricity by35%.
Heating Ring, Explosion-Proof High-Temperature Ceramic Heating RingUsage Precautions:
Working voltage shall not exceed 10% of the rated value; relative air humidity shall not exceed 95%, and there shall be no explosive or corrosive gases.
The wiring part should be placed outside the heating layer and insulation layer, and the outer 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.
The metal cast heater should be stored in a dry place. If the insulation resistance is lower than1MΩ due to long-term storage, it can be baked in an oven at about200degrees Celsius for5-6hours to restore normal. Alternatively, reduce voltage and energize to heat until the insulation resistance is restored.
The metal cast heater should be properly positioned and fixed, and the effective heating area must be closely attached to the heated object. Dry burning is strictly prohibited. If dust or contaminants are found on the surface, they should be cleaned promptly before reuse to avoid affecting heat dissipation and shortening service life.
