Abstract
For regulating process gases for heat treatments of metal materials/workpieces in industrial furnaces (), which have at least one treatment chamber (), at least one burnoff point () having at least one first valve (), and a regulator () having pressure meter (), the burnoff point () is only to be opened as a function of requirements related to the process gas. For this purpose, in a first step, with open first valve (), a quantity of a flushing gas () of the gas mixture () of the respective process gas is supplied in a controlled manner to the industrial furnace () and then burned off, in a second step, the valve () is closed, the industrial furnace () is regulated to a preset furnace pressure and this is permanently detected via the pressure meter (), in a third step, with the target pressure of the industrial furnace achieved, this pressure is detected via the pressure meter () and maintained, the first valve () further remaining closed. In a fourth step, the flushing gasification can be activated and adjusted. In the event of large pressure rise, in a fifth step, an overpressure flap () of the burnoff point () can be opened in a controlled manner via a fixed limiting value for pressure dissipation.
