摘要： For regulating process gases for heat treatments of metal materials/workpieces in industrial furnaces (1), which have at least one treatment chamber (2), at least one burnoff point (4) having at least one first valve (4.1), and a regulator (5) having pressure meter (5.1), the burnoff point (4) 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 (4.1), a quantity of a flushing gas (6.1) of the gas mixture (6) of the respective process gas is supplied in a controlled manner to the industrial furnace (1) and then burned off, in a second step, the valve (4.1) is closed, the industrial furnace (1) is regulated to a preset furnace pressure and this is permanently detected via the pressure meter (5.1), in a third step, with the target pressure of the industrial furnace achieved, this pressure is detected via the pressure meter (5.1) and maintained, the first valve (4.1) 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 (4.3) of the burnoff point (4) can be opened in a controlled manner via a fixed limiting value for pressure dissipation (FIG. 1).
