Abstract
A 'jet cooler' device for cooling and recirculating the gas forming the protective atmosphere in the cooling chambers of the furnaces for the continuous annealing of steel strips, comprises vertically arranged boxes (4) which extend in the furnace interior between successive vertically extending parallel strip sections, substantially over the whole length thereof, i.e., throughout the height of the furnace, and which have their walls (104) turned toward the facing adjacent strip sections provided with perforations (5). Associated to each vertically arranged perforated box (4) are a plurality of individual protective gas-cooling and recirculating units (6), which are distributed over the vertical extent of the respective box (4) and are attached to the outside of the furnace sidewalls (1). Each cooling and recirculating unit (6) comprises a heat exchanger (13) in form of a group of water-cooling rectilinear tubes, and a fan (11) that draws the protective gas from the furnace inside and cools it by causing the same to flow through the heat exchanger (13) and that blows this gas at a certain pressure into the associated vertically arranged box (4). The protective gas then flows out of the perforations (5) in the vertically arranged box (4) in form of jets directed to the facing surfaces of the adjacent strip sections.
