Batch-type annealing furnace for annealing steel strip or wire bundles has a protective hood positioned over an annular flange in a gas-tight manner with a heat exchanger lying above the flange

摘要

Batch-type annealing furnace has a protective hood (8), a radial blower, a heat exchanger (11) for cooling protective gas, and a deviating device for connecting a flow channel formed as an annular channel to the radial blower. The annular channel is arranged concentrically to an annular gap (12). The hood is positioned over an annular flange (9) in a gas-tight manner. The heat exchanger lies above the flange and the deviating device is formed as an annular deviating plate (18).
