Process for the continuous casting of a steel beam blank.

摘要

Process for manufacturing a beam blank steel, comprising the steps of: continuously casting a strand beam blank steel (24) with a cross section H-shaped having a central core (14) between two lateral wings (16¿, 16¿); cooling the blank strand steel beam (24) in a secondary cooling zone (26), wherein said blank strand steel beam (24) is guided in a vertical casting plane along a path curved, presenting its web (14) perpendicular to said vertical casting plane, so that each of said side flaps (16¿, 16¿) has an intrados flange tip (28¿, 28¿) and one end wing extrados (30¿, 30¿), wherein each of said intrados flange tips (28¿, 28¿) one intrados border surface (56¿, 56¿); said straightening beam blank strand steel after the secondary cooling zone; and have an energy alimentaciónexterna said wings (16¿, 16¿) between said cooling in said secondary cooling zone (26) and said straightening of said beam blank strand steel (24).
