ABSTRACT:
A continuous annealing furnace for a strip which is provided with a first treating furnace of horizontal type including at least a heating zone and a soaking zone, and a second treating furnace of vertical type disposed adjacent to the first treating furnace. The first treating furnace further includes a floating type transporting means which is composed of plural stages of floating type supporting devices for supporting the strip to be treated on them in a floating state, and a plurality of direction changing devices for transporting the strip from an upper stage towards a lower stage of the supporting devices, and the second treating furnace includes a plurality of rolls for transporting the material in a zigzag manner on vertically arranged multi-row passage. In this continuous annealing furnace, the strip is applied with an annealing treatment by being sequentially passed within the first and subsequent second treating furnaces, with the tension on the strip being controlled independently in each treating furnace by a plurality of bridle roll devices which are arranged at an inlet side of the first treating furnace, at an outlet side of the second treating furnace and a connecting portion between the first and the second treating furnaces.
