Working Principle
The working principle of the radiant electric heating tube is mainly to generate heat through the electric heating element, and then transfer the heat to the heated object through radiation. Specifically:
Electric heating element heating: The electric heating element (usually nickel-chromium alloy wire) generates heat after being energized, and transfers the heat to the sleeve made of heat-resistant stainless steel.
Radiant heat transfer: After the sleeve surface reaches a high temperature, it transfers heat to the surrounding heated objects through radiation.
Isolation protection: The electric heating element is installed inside the heat-resistant stainless steel sleeve, isolated from the external gas medium to avoid corrosion.
Application Scope
Radiant electric heating tubes are suitable for various industrial heating occasions, including but not limited to:
Industrial heating furnaces: Used for heat treatment, annealing, tempering of metal products.
Paint baking rooms: Quickly dry the coating surface and improve coating quality.
Food processing: Used for baking, drying, disinfection, and other processes.
Plastic molding: Preheat molds to accelerate molding speed.
Textile printing and dyeing: Used for preheating, drying, and curing of fabrics.
Usage Precautions
Environment identification: Fully understand the usage environment to determine whether radiant heat transfer is suitable.
Power selection: Choose the appropriate power according to the required effective working temperature, and pay attention to the power load issue.
Temperature control: Understand the working temperature requirements of the electric heating tube and select the appropriate power electric heating tube.
Dry burning prevention: It is strictly forbidden to place the electric heating tube in an environment without sufficient medium for dry burning, especially for electric heating tubes that need to be immersed in a medium.
Heat dissipation consideration: If the electric heating tube needs to be dry burned in air, consider the heat dissipation effect of the usage environment to avoid overheating.
Conclusion
As an efficient heating element, the radiant electric heating tube is widely used in many industries due to its high efficiency and long service life. Through proper use and maintenance, its stable and reliable operation can be ensured to meet various heating needs.
