Frequently Asked Questions (FAQs)

Why does the atmosphere inside the furnace need to be controlled at all?
Because metal reacts with oxygen when heated. That reaction forms scale on the surface, which damages the finish and affects the final properties of the material. The atmosphere inside the furnace keeps oxygen away from the metal throughout the entire cycle. Lose control of it at any point, and the surface is compromised—there is no fixing that after the fact.
Before heating starts, nitrogen is circulated inside the inner cover to push all the air out. Once the air is cleared, hydrogen or the required gas mix is introduced. The pressure inside stays between 2 and 6 kPa throughout the cycle. At the end, nitrogen clears the hydrogen out before the cover comes off. Both steps are straightforward, but neither is optional.
Two things. First, any remaining oxygen reacts with the metal surface during heating and causes oxidation. The surface finish is damaged and cannot be recovered. Second, hydrogen and air together are flammable within a certain concentration range. The purge step protects both the product and the people working around the furnace. It is not a step that can be skipped or rushed.
It handles multiple processes. Bright annealing, spheroidised annealing, normalising, and others can all be run on the same furnace by adjusting the atmosphere composition, the temperature, and the heating and cooling rates. The furnace does not change — the process parameters do. What material you are working with and what result you need determines how the cycle is set up.
Oxygen probes or oxygen-hydrogen analyzers are fitted to track the atmosphere inside the inner cover in real time. If something shifts outside the required range, the control system catches it and adjusts. A standard setup uses an oxygen probe. A more advanced setup uses a full oxygen-hydrogen analyser, which gives more accurate, detailed data across the entire cycle.
It does. Ceramic fibre insulation heats up and cools down faster than brick lining. Shorter cycles mean the metal spends less time at high temperature, which reduces the risk of surface reactions even if the atmosphere fluctuates slightly. It also means less energy per batch. Over time, in a facility running multiple cycles a day, that difference is significant.
Once heating is done, the heating bell is lifted and a cooling cover goes on in its place. The cooling cover uses a fan to bring the temperature down by drawing outside air across the outer surface of the inner cover. The protective atmosphere inside stays in place the whole time. The inner cover is only opened once the metal has cooled below the temperature at which it would react with air. Opening it too early damages the surface that the entire process was meant to protect.
A standard system includes the furnace, a control panel, an ammonia cracker for gas generation, and an oxygen probe for monitoring. A high-specification system replaces the basic probe with a full oxygen-hydrogen analyzer. That gives you more detailed, real-time data on the atmosphere throughout the cycle rather than just a single measurement point. If you are processing materials with tight surface quality requirements or running high-volume production where consistency across every batch matters, the upgraded system is worth it.
