What Is an Annealing Furnace?
An annealing furnace is a large heating device for applying an annealing process. It can heat various materials such as metals, semiconductors, and glass to high temperatures. Annealing is a technology that corrects distortions in or increases the stability of an object by heating it. For example, plastics are heated to increase crystallization, or metals are heated to uniform hardness. An annealing furnace is widely used for annealing a variety of materials for industrial and research applications.
Uses of Annealing Furnaces
Because many materials require annealing, annealing furnaces are used in various locations.
- Processing of crystalline plastics By heating crystalline plastics, the degree of crystallinity can be increased, and stability can be improved.
- Moisture Removal from Plastics Plastics absorb moisture, even from the air, and expand. Therefore, plastics are heated in annealing furnaces to remove moisture and correct their size and dimensions.
- Treatment of Metals By heating metals, hardness can be made uniform, and stability can be improved.
Principle of Annealing Furnaces
Annealing furnaces use a variety of heating methods. Hot-air and infrared methods are used, but we introduce high-performance far-infrared annealing furnaces here.
Far-infrared annealing furnaces are annealing furnaces that heat using the "radiation" property of far-infrared radiation. Standard heating methods include directly applying a heat source to the object to be heated or applying hot air to warm the object. However, both methods require touching the object, and non-contact heating is impossible. Compared to these methods, the method using far-infrared rays can raise the temperature without directly touching the object.
Far-infrared radiation is an electromagnetic wave with a longer wavelength than visible light. Irradiating an object with far-infrared rays causes the molecules that make up the object to vibrate and generate heat energy. Since this thermal energy warms the object, non-contact heating is possible. In addition, high temperatures can be created in a short time. Furthermore, the heating temperature varies depending on the wavelength of the far-infrared radiation, making it excellent in that it can be used in different ways depending on the object to be heated.
