Abstract
The continuous steel-sheet heat-treatment plant comprises, in sequence, a zone in which the sheet is heated to a temperature above the recrystallization temperature, a zone in which the sheet is held at this temperature for more than 30 seconds, a rapid cooling zone, an optional overaging zone, and a final cooling zone. The rapid cooling zone has devices for spraying a cooling fluid and a tank containing an aqueous bath at above 75.degree. C.
