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, such as round, flat, right-angle, air-cooled, water-cooled, and other special shapes. After precision machining, it can closely fit the heated object.
Ceramic heating ringsurface load can reach4.5-6.5w/cm2, maximum working temperature400-550℃;
Ceramicmanufactured heater is a high-efficiency 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 service life, good thermal insulation performance, strong mechanical properties, corrosion resistance, and magnetic field resistance. Adding an 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 must not exceed the rated value by10%; relative air humidity not greater than95%, 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 stored for a long time and the insulation resistance is lower than1MΩ, it can be baked in an oven at about200degrees Celsius for5-6hours to restore normal condition. 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 in close contact with the heated object. No dry burning is allowed. If dust or contaminants are found on the surface, clean them promptly before reuse to avoid affecting heat dissipation and shortening service life.
