Method and device for regulating process gases for the thermoforming of metallic materials/workpieces in industrial ovens

摘要

the settlement of prozessgasen for heat treatment of metallic materials / parts in industrial furnaces (1), at least one room (2), at least one abbrandstelle (4) with at least a first valve (4.1) and a system (5) with a pressure gauge (5.1) in the abbrandstelle (4) only in dependence prozessgasbedingter needs to be opened up.this is a first step in the first valve (4.1) a quantity of a spu00fclgases (6.1) of the mixture (6) of the respective gases of the industrieofen (1) controlled to and then burned in a second step, the valve (4.1), the industrieofen (1) e a preset furnace pressure regulated and this permanently on the pressure gauge (5).1) covers, in a third step with levels of solldruck of industrieofens this pressure on the pressure gauge (5.1) is collected and held, and the first valve (4.1) still remains closed. in a fourth step, the spu00fclbegasung enabled device. with great pressure, in a fifth step, a u00fcberdruckklappe (4).3) the abbrandstelle (4) controlled by a fixed threshold value is corrected to be opened (fig. 1).
