Importance of Tempering Furnace Heating Elements

Operating Principle of Tempering Furnaces

• The metal is placed into the furnace and heated to the desired temperature.
• The temperature is controlled by thermostats inside the furnace.
• The metal is held at this temperature for a certain period.
• The metal is then removed from the furnace and cooled in a controlled manner.
• Cooling can be achieved using air, water, or oil.

Heaters Used in Tempering Furnace

• Nickel-chromium heaters: The most commonly used type of heater. They are resistant to high temperatures (up to 1200°C) and have a long lifespan.
• Kanthal heaters: More expensive than nickel-chromium heaters, but can withstand higher temperatures (up to 1300°C).
• Ceramic heaters: Used at lower temperatures (up to 600°C). They consume less energy compared to nickel-chromium and Kanthal heaters.
