Steel strip continuous annealing furnace.

摘要

A steel strip continuous annealing furnace comprises a heating zone (21), a soaking zone (22) and cooling zones, (23,24) wherein bridle rolls (25, 26, 27, 28) 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 appriate 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.
