Vacuum Normalizing Furnace
Vacuum Normalizing Furnaces are key equipment for industrial heat treatment. They heat metals to above their phase transition temperature in a vacuum environment, hold the temperature, and then slowly cool them. This process eliminates stress, refines grains, and improves material toughness and uniformity. They are widely used in batch processing of workpieces such as bearing steel and alloy structural steel, ensuring stable performance.

FAQ
Focus on answering common questions to provide users with clear and practical usage guidelines:
-
Q:What are the characteristics of the vacuum normalizing equipment's chamber material?
A:The chamber is made of high-temperature resistant alumina ceramic fiber, which provides excellent thermal insulation and is non-reactive with the workpiece.
-
Q:How does the hardness of a workpiece change after normalizing?
A:Compared to the pre-treatment hardness, the hardness typically decreases slightly or remains stable, but the distribution becomes more uniform. Due to grain refinement and a more homogenized structure, toughness and machinability are significantly improved.
-
Q:What are the differences between different cooling media during the normalizing process?
A:Argon has a higher density than nitrogen and a slightly higher thermal conductivity. It cools faster at the same pressure and is suitable for materials requiring high cooling rates. Nitrogen, on the other hand, is less expensive and offers a moderate cooling rate. It is commonly used for normalizing cooling of ordinary carbon steel. The appropriate medium should be selected based on the material's characteristics.
