Although the heat treatment fixture throughout the heat treatment process is only a small part, but its influence should not be overlooked, the quality of heat treatment to be largely dependent on it. Therefore, the heat-treatment tooling and test timber are to be careful.

Heat treatment in the selection of tooling materials roar, the main consideration is the four factors, one is the main component and tooling characteristics; the other is to use the maximum temperature tooling bear; there is the influence of factors tooling life; and high temperature furnace corrosion of. The combination of these four factors, heat treatment tooling is now commonly used in most heat-resistant steel.
However, due to the practical application conditions, changes in the furnace atmosphere, different materials of the highest temperature will be different, so when tooling selection based on specific conditions. In order to maintain good heat steel tooling life, it is best to work continuously at a certain temperature, reduce the number of shutdown.
Since the heat treatment tooling difficult to detect its data, so basically rely on experienced technical staff to determine, for example, generally use the visual appearance, if the deformation is too large, the impact of charging into the furnace and normally need to be replaced; aspects of life We rely on speculation or experience measure, try to focus on the replacement together.
