In a method for the production of hot-rolled wide strip in a production plant which includes a continuous casting plant for thin slabs having a thickness of between 40 and 70 mm, an equalizing furnace and a rolling mill, wherein the temperature of the thin slab when exiting the continuous casting plant is above 950°C, the surface temperature of the slab is lowered between the continuous casting machine and the equalizing furnace over a sufficient depth of the slab, so that a conversion of the structure from austenite to ferrite/pearlite takes place.
Procédé de production d'une large bande à chaud dans une installation de production comprenant une installation de coulée continue de brames minces, de 40 à 70 mm d'épaisseur, un four d'équilibrage et un laminoir. La température de la brame mince à sa sortie de l'installation de coulée continue est supérieure à 900 degrés Celsius et la température de la surface de la brame est abaissée entre la machine de coulée continue et le four d'équilibrage sur une épaisseur suffisante pour qu'une conversion s'opère dans la structure et que l'austénite se transforme en ferrite et en perlite.
