Electric furnaces can reach very high temperatures, but the exact maximum depends on the type of furnace and its heating elements.
What is the maximum temperature of electric furnace? (4 Types Explained)
1. Industrial Electric Arc Furnaces
Industrial electric arc furnaces can reach temperatures up to 1,800 °C (3,300 °F).
2. Laboratory Electric Furnaces
Laboratory units can exceed 3,000 °C (5,400 °F).
3. Gas Furnaces
Gas furnaces can reach different maximum temperatures depending on the type of gas used and the pressure applied.
- Furnaces using illuminating gas made from coal and air at 2 or 3 lb. pressure can reach a maximum temperature of about 1,400 °C.
- When burning natural gas, temperatures 100 °C or 200 °C higher may be attained.
- With higher air pressures and illuminating gas, temperatures as high as 1,650 °C can be achieved.
- In the case of natural gas, temperatures as high as 1,800 °C are possible.
- The addition of oxygen and other factors can further increase these temperatures.
4. Muffle Furnaces
Muffle furnaces, commonly used in laboratories, can have varying maximum temperatures depending on the type of heating elements installed.
- Metallic wire heating elements have a temperature range of 1,000 °C to 1,200 °C.
- Molybdenum disilicide heating elements can reach temperatures as high as 1,800 °C.
5. Tube Furnaces
Tube furnaces, designed to heat samples contained within a work tube, can have maximum operating temperatures ranging from 1,100 °C to 2,600 °C, depending on the product range and type of heating elements used in their construction.
Safety Considerations
It's important to note that the maximum temperature of the heating elements must be safely higher than the required temperature of the furnace or load. The safety range is typically 50 °C to 200 °C higher than the desired temperature.
