Abstract (en)

[origin: EP1462529A1] Furnace contains annealing base for location of annealed product, protecting cap, gasproof installed over annular flange, located in base centrifugal blower with impeller, directing mechanism with blades for circulation of protective gas in protecting cap, located under annular flange heat exchanger for cooling of protective gas, which from the side of inlet is connected through flow passage to thrust face of centrifugal blower, and from the side of inlet it falls into annular clearance between directing mechanism and protecting cap, and transferred axially deflecting device, located from thrust face of centrifugal blower for selective conjunction of directing mechanism to heat exchanger flowing channel to centrifugal blower, at that between directing mechanism and protecting cap it is cylindrical wall, separating external annular clearance from concentric to it internal annular channel, forming flow passage between cylindrical wall and external perimeter of directing mechanism, cylindrical wall bears deflecting device, which is implemented in the form of annular deflecting gate enveloping on the outside directing mechanism.
