Title:
加熱装置
Document Type and Number:
Japanese Patent JP5074707
Kind Code:
B2
Abstract:
Heat deformation of a front side of a heating chamber in its thickness direction is prevented, and therefore a uniform temperature distribution within, and a low heat loss from, the heating chamber is enabled, by using a bimetal plate as at least a front portion of an inner surface of the heating chamber, without an increase in size and production cost of heat treatment apparatus and without involving complex design and complicated adjustment operations. A heating chamber 1 has an inner surface. A front member 41 of the inner surface includes a bimetal made of an outer material 411 with a high thermal expansion coefficient and an inner material 412 with a low thermal expansion coefficient. As an example, the outer material 411 is SUS304, and the inner material 412 is SUS430. This prevents the front member 41 from being deformed in a thickness direction thereof by a possible temperature gradient between the inner and outer sides of the front member 41.
