Technical Field
The utility model belongs to the technical field of atmosphere control system technique and specifically relates to a surface treatment equipment atmosphere control system.
Background
Most nitriding furnaces decompose ammonia gas at a certain temperature to generate nitrogen and hydrogen to carry out nitriding treatment, wherein the nitrogen potential strength depends on the ammonia decomposition rate, the ammonia decomposition rate depends on the amount of the ammonia gas introduced into the furnace, and the more the ammonia is fed, the lower the ammonia decomposition rate is and the higher the nitrogen potential strength is; the smaller the amount of the feed, the higher the decomposition rate of ammonia and the lower the nitrogen potential intensity. Domestic original equipment adopts straight-through ammonia interface, can't realize the control that becomes more meticulous of ammonia volume of letting in, can only rely on experience accumulation and artifical timing to estimate and control stove atmosphere, can't realize the accurate control of stove atmosphere.
