Arrangement And Installation Of Cartrige Heater In Electric Heating Equipment
It has a great influence on the temperature uniformity of the electric heating equipment and the service life of the cartridge heater. Here are the basic requirements for cartridge heater installation:
1. Ensure that the furnace temperature is evenly distributed.
2. The installation method generally adopts three installation methods, the corrugated type of the filament heater, the corrugated type of the spiral heater and the corrugated type of the belt heater.
3. High-aluminum products should be selected for the support of the heating tube of the medium temperature furnace. The high-temperature furnace with the furnace temperature above 1000 ℃ should use relatively pure alumina products, and the low-temperature furnace can use general clay products.
4. Minimize the radiation shielding between the electric heating tubes and between the supporting bricks on the furnace wall. The location of the cartridge heater should be such that the heat can be easily transferred to the workpiece without overheating the workpiece locally.
