A new vacuum hood furnace was put into operation at the PZPS, which significantly improved the quality of the tape produced

A new vacuum hood furnace has been put into operation in the PZPS physical laboratory. This significant step made it possible to improve heat treatment processes, which had a positive impact on the quality of the final product and made it possible to increase the efficiency of the production of precision alloys and steels in general.

Advantages of a vacuum hood oven

This furnace is designed for carrying out various thermal treatments (usually annealing) in vacuum at temperatures up to 1500℃. It is an environmentally friendly equipment and has a number of advantages that significantly improve quality heat treatments:

• A deep vacuum. The new furnace makes it possible to obtain a vacuum of about 10^-5-10^-6 Pa, which is significantly higher than that of similar equipment. This makes it possible to obtain better magnetic properties in materials.
• Improved fasteners. Due to the increased strength of the structural fasteners, the new furnace makes it possible to make the annealing process more “clean”, eliminating the ingress of undesirable substances from outside.
• Automatic control. One of the key advantages is the ability to operate the vacuum furnace in a fully automatic mode, which eliminates the influence of the human factor and ensures the stability of thermal processes.
• Emergency shutdown system. It improves the safety of equipment operation, since in the event of an unplanned shutdown of water supply, it automatically stops the operation of the vacuum furnace.

The introduction of a vacuum hood furnace had a positive effect on quality soft magnetic alloys (49K2FA, 27KH, 50N, 50NP, 79NM), reducing coercive force and increasing magnetic permeability and saturation induction. The commissioning of new equipment also led to a significant improvement in the properties of materials that are in demand in modern industry — electrical steels (20895, 20880, 20860) that are always available at our plant.

The installation of a hood furnace is just the beginning of a new phase in our research and development. The PZPS Physical Laboratory is ready for further development and introduction of advanced technologies to achieve outstanding results in science and industry.
