MULTI-PURPOSE PROCESSING LINE FOR THERMAL TREATMENT AND COATING APPLICATION AS A RESULT OF IMMERSION INTO STEEL STRIP MELT

摘要

A multipurpose continuous processing line able for heat treating and hot dip coating a steel strip comprising: —an annealing section (1) for heating the steel strip to a predetermined annealing temperature and for maintaining the steel strip at said annealing temperature, —a first transfer section (2), —an overaging section (3) able to maintain the temperature of the steel strip between 300° C. and 700° C., —a second transfer section (4) able to adjust the temperature of the steel strip to allow the hot dip coating of the strip and, —a hot dip coating section (5), wherein the first transfer section (2) comprises, in sequence, cooling means (21) and heating means (22).
