Estimating the term…
A steel strip continuous annealing furnace comprises a heating zone, a soaking zone and cooling zones, wherein bridle rolls for isolating tension of a steel strip from those in adjacent sections of the steel strip are provided at the inlet and outlet of the furnace and in the furnace so as to define a plurality of tension control blocks and provide tension control mechanisms for controlling the tensions of the steel strip in the respective tension control blocks, so that appropriate tensions can be rendered to the steel strip in the respective zones of the furnace, thereby enabling to secure the safe and satisfactory operating conditions.
A steel strip continuous annealing furnace comprising a heating zone, a soaking zone or a heating-soaking zone and cooling zone, wherein a plurality of sets of bridle rolls engaging with a steel strip to isolate tension of the steel strip in the longitudinal direction of the steel strip are provided at the front outer side and at the back outer side of the furnace and within the furnace so as to define a plurality of tension control blocks between each of adjacent said bridle rolls, and a plurality of tension control mechanisms are provided for each of said tension control blocks for controlling the tension of the steel strip isolated within of said tension control blocks whereby the tension within each tension control block can be controlled independently of the tension in other said tension control blocks.
