ABSTRACT:
A continuous annealing line for annealing a cold-rolled strip of a ultra-low-carbon steel comprising a heating furnace for heating the strip which is fed continuously, with or without a soaking furnace following the heating furnace, a cooling furnace in which the heated steel strip is cooled, and a carburizing
itriding furnace disposed between the heating furnace or the soaking furnace and the cooling furnace. The carburizing
itriding furnace may be divided into a plurality of zones, each of which is provided with control means for controlling the carburizing
itriding atmosphere and carburizing
itriding temperature in the zone. The continuous annealing line may further comprise a plurality of carburizing
itriding furnaces and have an arrangement for conducting a switching between a mode in which the carburizing
itriding furnace is used for carburizing
itriding the steel strip and a mode in which the carburizing/cooling furnace is used for cooling the steel strip.
