    • The apparatus of the present invention includes a molten metal vessel system for casting molten metal, the system comprising: (a) a vessel (1) containing molten metal (2) adapted to contain and dispense the molten metal (2) for casting, the vessel (1) having interior surfaces (8) and the molten metal forming an upper surface (9); (b) a submerged entry nozzle (3) exiting below the upper surface (9); and (c) a surface and/or a submerged flow modifier member (7, 11) disposed between at least one of the interior surfaces (8) and the submerged entry nozzle(3). The surface and/or submerged flow modifiers (7, 11) work to impede the formation of waves in the upper surface (9) of the molten metal (2). The present invention also includes a method for improving the quality of a continuous casting process.

    • A device used in vessels for casting molten metals such as steel comprises a so-called inner spout (2) of refractory material, a fixed circular plate (3) of refractory material having an axial hole coincident with that of the nozzle (2), a movable circular plate (4) of refractory material having a hole centred about the axis (23), and a so-called collecting nozzle (5) of refractory material, integral with the movable plate (4), for stabilizing the deflected jet. The movable plate (4) can undergo a displacement (17) along a straight line or other path so as to close, to a greater or lesser extent, the hole in the fixed plate (3). The movable plate (4) can also pivot about its axis (23). The symmetry of the shape of the various refractory elements with respect to their orifices, through which the hot metal flows, confers on the assembly optimal properties of dilatation and resistance to thermal shock. As the plate (4), and possibly the plate (3), can be pivoted about their respective axes, the wear on the holes can be distributed symmetrically and the amplitude of the displacements can be reduced.
    • 用于铸造诸如钢等熔融金属的容器中使用的装置包括所谓的耐火材料内喷嘴(2),具有与喷嘴(2)重合的轴向孔的耐火材料的固定圆板(3) 具有以轴线(23)为中心的孔的耐火材料的可动圆板(4)和与可动板(4)成一体的所谓的耐火材料收集喷嘴(5),用于稳定偏转的射流。 可移动板(4)可以沿着直线或其他路径经受位移(17),以便或多或少地关闭固定板(3)中的孔。 可移动板(4)也可绕其轴线(23)枢转。 各种难熔元件相对于它们的孔的形状的对称性,热金属流过该孔的形状赋予了组装膨胀的最佳特性和抗热冲击的优点。 由于板(4)和可能的板(3)可以围绕其各自的轴线枢转,所以孔的磨损可以对称地分布,并且位移的振幅可以减小。
