The method for manufacturing steel sheet comprises the steps of: rough-rolling to form a sheet bar; finish-rolling the sheet bar to form a steel strip; applying primary cooling and secondary cooling to the finish-rolled steel strip; and coiling the secondary-cooled steel strip. The primary cooling is conducted at cooling speeds of 120.degree. C./sec or more down to the temperatures of from 500 to 800.degree. C. The secondary cooling is conducted at cooling speeds of less than 60.degree. C./sec.

El método para fabricar la hoja de acero abarca los pasos de: a'spero-balanceo para formar una barra de la hoja; acabar-balanceo la barra de la hoja para formar una tira de acero; aplicación de refrescarse primario y de refrescarse secundario a la tira de acero acabar-rodada; y arrollando la tira de acero secundario-refrescada. El refrescarse primario se conduce a las velocidades que se refrescan de 120.degree. C./sec o más abajo a las temperaturas de a partir del 500 a 800.degree. C. El refrescarse secundario se conduce a las velocidades que se refrescan de menos que 60.degree. C./sec.
