For a number of years now heat treating of automotive brake rotors has involved Ferritic Nitrocarburizing (FNC) in large tip up furnaces (generally but not always we will stress).

It would appear that “Nitrex” has come up with a different approach, one that will be in production in the very near future.

The furnace system you are seeing in these photos is in the final stages of testing at the Nitrex facility in Poland. The furnace is designed for around 600,000 rotors per year based upon 46 weeks/year, 5 days a week/24 hours a day with a “charge” every 2 hours. The furnace will be the first of two destined to be installed in Northwestern Europe.  This system has exceeded all design criteria from heating rate, cooling rate and layer thickness/uniformity.

As mentioned the system with be doing  Ferritic Nitrocarburizing with consistent oxide layer and color.

In addition to these photos a video can be viewed below.
