    摘要: A device for cooling and guiding a beam blank in a curved secondary cooling zone of a beam blank caster includes an intrados web support roller with a cylindrical bearing surface that is interrupted by grooves. The grooves are designed so as to avoid an over-flow generating cooling water dam up behind the intrados web support roller by channeling sufficient cooling water underneath the intrados web support roller axially through the intrados channel of the beam blank. The cooling water overflow produces a quench of the intrados tips of the flanges, which results in transverse cracks of these tips during straightening of the beam blank.

    摘要: A method for producing a steel beam blank includes continuously casting a steel beam blank strand and cooling the steel beam blank strand in a secondary cooling zone. The steel beam blank strand is guided in a vertical casting plane along a curved path having its web perpendicular to the vertical casting plane, so that each of the lateral flanges has an intrados flange tip and an extrados flange tip. The method further includes straightening the steel beam blank strand behind the secondary cooling zone. When being straightened, the intrados flange tips are selectively reheated between the secondary cooling and the straightening of the steel beam blank strand via an external energy supply focused on the intrados flange tips. In this manner, transverse cracks in the intrados flange tips may be reliably avoided.
