    • A crucible (11) for use in a continuous casting process using upwards feed induced by gas pressure within a surrounding casing (10) consists of a monolithic or one-piece crucible body (28) of refractory material defining a melt chamber (29) having a charging opening (30) at one end and a melt outlet (31) at the opposite end, the melt outlet communicating with a die feed port (35) by way of ducts (32, 34) extending through the crucible body. The melt chamber and the ducts are formed in the body by machine-boring or drilling. The melt outlet (31) also communicates with a narrowed drain port (33B) near which are cooling probe recesses (38) for receiving cooling probes (44) to effect a drain plug of "frozen" melt. The plug is cleared to drain the crucible completely simply by withdrawing the cooling probes.

    • Disclosed is a mold assembly characterized by efficient and controlled removal of heat from molten metal during continuous casting, providing high casting speeds in conjunction with superior surface finish on the cast product. The mold assembly includes a refractory mold body having a longitudinal solidification chamber therein and a plurality of longitudinal cooling bores spaced around the solidification chamber. The cooling bores extend only partially through the mold body in the direction of the solidification chamber to define an insulating section adjacent the inlet end thereof to minimize heat removal from the molten metal source and a cooling section adjacent the outlet end when cooling probes containing a circulating coolant are inserted into the cooling bores. The cooling probes are adjustable along the length of the cooling bores to accurately control the position of the solidification front in the solidification chamber and provide optimum heat transfer from the molten metal for rapid solidification with superior surface finish. In a preferred embodiment, the mold assembly includes a longitudinal bore defining a plurality of solidification chambers of increasing diameter in the direction of the outlet end for producing two or more diameters of cast product by positioning the solidification front first in one chamber and then another by suitable adjustment of the cooling probes.
    • 公开了一种模具组件,其特征在于在连续铸造期间有效和可控地从熔融金属中去除热量,提供高铸造速度以及铸造产品上的优异表面光洁度。 模具组件包括其中具有纵向凝固室的耐火模具体和围绕凝固室间隔开的多个纵向冷却孔。 冷却孔仅在凝固室的方向上仅部分地延伸穿过模具本体,以限定邻近其入口端的绝缘部分,以使包含循环的冷却探针时的熔融金属源和邻近出口端的冷却部分最小化热量 冷却剂插入冷却孔。 冷却探针可以沿着冷却孔的长度调节,以精确地控制凝固室中的凝固前沿的位置,并提供从熔融金属的最佳热传递,用于快速固化,具有优异的表面光洁度。 在优选实施例中,模具组件包括纵向孔,该纵向孔限定了在出口端的方向上增加直径的多个凝固室,用于通过将固化前沿首先定位在一个室中,然后另一个通过 适当调整冷却探针。
