Abstract

LA INVENCION SE REFIERE A UN PROCESO DE FABRICACION DE UNA CHAPA DE ACERO DULCE BAJO DE CARBONO POR LAMINACION EN CALIENTE DE UN DESBASTE, Y A CONTINUACION LAMINACION EN FRIO DE LA CHAPA LAMINADA EN CALIENTE, Y RECODIDO DE LA CHAPA LAMINADA EN FRIO EN EL QUE EL RECODIDO DE LA CHAPA LAMINADA EN FRIO ES UN PRIMER RECODIDO CONTINUO QUE CONTROL EL CONTENIDO DE CARBONO EN SOLUCION EN EL ACERO Y EN QUE TRAS ESTE RECOCIDO, SE SOMETE LA CHAPA A UN SEGUNDO RECOCIDO A BAJA TEMPERATURA QUE PRECIPITA EL CARBONO EN SOLUCION EN FORMA DE CARBURO DE HIERRO. LA INVENCION SE REFIERE TAMBIEN A UNA CHAPA DE ACERO DULCE OBTENIDA POR ESTE PROCESO.
