What is a Annealing furnace?

An annealing furnace is a large heating device for annealing. Various materials such as metal, semiconductors, and glass can be heated to high temperatures. Annealing is a technique that heats an object to correct the distortion of the material and improve its stability. For example, heating plastic to increase crystallization and heating metal to make hardness uniform. Annealing furnaces are widely used to anneal various materials for industrial and research purposes.
