What are the components of the high-temperature experimental electric furnace?

1. Heating element: According to different temperature requirements, different electric heaters are used as heating elements.

2. Temperature measuring element: The temperature measuring element of the experimental electric furnace adopts thermocouple to measure temperature, and the main models used are: K, S, B thermocouple.

The thermocouple wire of the K graduation number is made of nickel-chromium-nickel-silicon, and the temperature measurement range is 0-1100 degrees;

The thermocouple wire with S index number is made of platinum rhodium 10-platinum, and the temperature measurement range is 0-1300 degrees;

Type B thermocouple wire is made of platinum-rhodium alloy, and the temperature measurement range is 0-1800 degrees.

3. Temperature control instrument: The electric furnace developed and produced by the high-temperature electric furnace adopts 30-segment and 50-segment intelligent electric furnaces.

4. Furnace of electric furnace: commonly used materials are corundum, alumina, high-purity alumina, Morgan fiber, silicon carbide, etc.

5. Insulation furnace lining: The main function of the furnace lining is to ensure the stability of the furnace temperature and reduce heat loss as much as possible. Use insulating materials near the furnace shell and refractory materials near the heating element.

6. Furnace body Furnace shell: generally adopts a double-layer shell structure, and the box shell plate is made of high-quality carbon steel and cold-rolled steel plate, which is cut, folded, and welded by precision CNC machine tools, which is strong and durable;

7. Power lead: The function of the power lead is to ensure the safe connection between the heating element and the power source. Generally copper, three-phase or three-phase power is used, and a certain cross-sectional area is required, otherwise it will be heated or even burned. The power lead It should be insulated from the furnace shell.
