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.

摘要： A seal for use around a rod electrode passing along an axis through a hole in the wall of a furnace into the interior of the furnace has an annular and at least limitedly flexible seal ring fitted snugly around the electrode in the hole and a holder carrying the seal ring and sealingly engaged with the furnace wall. Thus gas flow through the wall at the hole past the seal ring is substantially blocked. The seal assembly has structure forming with the electrode and seal ring a substantially closed chamber surrounding the electrode axially inward into the furnace from the ring. This chamber is pressurized at superatmospheric pressure with an inert gas and the electrode is cooled inward of the furnace from the seal ring. The seal ring is compressed axially by a packing assembly so it is pressed radially against the electrode. The packing includes rigid split compression rings bearing axially on the seal ring.

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.
摘要翻译：用于冷却和引导梁坯坯弯曲二次冷却区中的梁坯件的装置包括具有由凹槽中断的圆柱形支承表面的内侧腹板支撑辊。凹槽的设计是为了避免产生溢流产生的冷却水通过内侧腹板支撑辊下面的足够的冷却水轴向地穿过梁坯体的内部通道而在坝内支撑辊后面阻塞。冷却水溢流产生法兰突入尖端的淬火，这导致在梁坯体矫直过程中这些尖端的横向裂纹。
