Principle and Application of Tungsten Rod Heating Technology

We can provide a detailed explanation of the principle and application of Tungsten Rod heating technology from the following aspects:
1. Heating principle
Resistance heating: As a commonly used heating element, the heating principle of molybdenum rod is mainly based on resistance heating. When the current passes through the molybdenum rod, heat is generated due to the resistance of the molybdenum rod itself. This heat increases with the increase of current, thereby achieving the purpose of heating.
Joule heating effect: When the molybdenum rod is electrified, the current passes through the resistance wire of the molybdenum rod to generate Joule heating effect. When current passes through a wire, it generates heat, which is called Joule heating. By adjusting the current, the heating temperature can be controlled.
2. Application
Medium frequency furnace heating: In the medium frequency furnace, molybdenum rods are used as heating elements. The high melting point, high strength, and excellent heat resistance of molybdenum rods enable them to withstand high temperatures and solution corrosion, making them the preferred heating element for medium frequency furnaces. Molybdenum rods can quickly increase furnace temperature, shorten casting time, and improve production efficiency through resistance heating.
High temperature furnace: The application of molybdenum rods in high-temperature furnaces is mainly reflected in their role as heating elements. Molybdenum rods have high temperature strength, high temperature stability, and good oxidation resistance. They can be heated by a large current to quickly raise the temperature inside the furnace to the desired level and maintain stability. This makes molybdenum rods an ideal material for high-temperature furnaces.
Metal melting and casting: Molybdenum rods are suitable for melting and casting various metals, including steel, iron, copper, aluminum, aluminum alloys, etc. Molybdenum rods can maintain stable performance at high temperatures, are not easily deformed or broken, and can meet various industrial production needs.
3. Precautions
Choose the appropriate molybdenum rod: When selecting molybdenum rods, it is necessary to choose the appropriate specifications and sizes based on different furnace types and metal materials. Molybdenum rods should have characteristics such as high temperature stability, good thermal conductivity, and good corrosion resistance.
The selection of surface load: Based on the structure, working atmosphere, and temperature of the heating equipment, the correct selection of surface load for the heating element is the key to the service life of the molybdenum rod heating element.
In summary, molybdenum rod heating technology has been widely used in fields such as metal melting and casting, medium frequency furnace heating, and high-temperature furnace tools due to its unique resistance heating principle and excellent performance characteristics. In practical applications, it is necessary to pay attention to selecting appropriate molybdenum rods and setting heating parameters correctly to ensure heating effect and production safety.
