Heat treatment in vacuum furnaces provides a cleaner environment by reducing atmosphere levels to a minimum, especially molecules of oxygen. The result is a non-reactive condition, where metals can be heat treated. Aluminum and other alloy brazing is preferred for high-end products, due to the cleanliness and absence of flux.
Monitoring product temperatures throughout the process establishes uniform heating in the vacuum chamber and identifies any hot or cold spots. If the process includes a gas quench, it is critical to monitor product cooling rates, which preserves the final molecular characteristics of a product.
- Monitor product temperatures through heating and quench processes
- Establish uniformity throughout the product load
- Identify any hot or cold spots within the working volume
- Set up new product recipes more efficiently
