Abstract
A continuous cold rolling and annealing apparatus for a steel strip so that interruption of a cold rolling mill part does not directly cause a continuous annealing furnace part to be interrupted, in which apparatus at least one cold rolling mill is located upstream of the entrance of a continuous annealing furnace and an intermediate reel for supplying a spare steel strip coil to said continuous annealing furnace, is arranged between the cold rolling mill and the continuous annealing furnace.
Claims5
A continuous cold rolling and annealing apparatus for a steel strip, comprising:
- a continuous annealing furnace having a heating zone;
- at least one cold rolling mill located upstream of the entrance of said continuous annealing furnace for cold rolling a steel strip;
- an intermediate reel for supplying a spare steel strip to said continuous annealing furnace when the supply of the steel strip from the cold rolling mill is interrupted, said intermediate reel being located between said cold rolling mill and said continuous annealing furnace;
- a welder for connecting said spare steel strip to a previously processed steel strip, said welder being located between said intermediate reel and said continuous annealing furnace;
- a coil car for supplying a spare steel strip coil to said intermediate reel;
- and
- a coil skid which is capable of holding a plurality of spare steel strip coils thereon and of moving each spare steel strip to a predetermined position for supplying it to said coil car.
