摘要： The present invention discloses an apparatus for direct chill casting of metal comprises an open ended mold cavity formed by a casting surface with an upper end and a lower end, a refractory sleeve located at the upper end of the mold cavity being adapted to receive molten metal, a coolant delivery system below the lower end of the mold for supplying coolant to chill the descending hot metal body, and a boron nitride ring mounted between the refractory sleeve and the peripheral wall of the mold cavity. In another embodiment, the apparatus for direct chill casting of metal further includes a downspout instead of a refractory sleeve that is located at the upper end of the mold cavity being adapted to receive molten metal having a flow control rod or a floating baffle where the flow control rod controls the amount of molten metal to enter the mold cavity. In a further embodiment, a process for the direct chill casting of a metal comprising the steps of continuously filling the upper end of the cavity with molten metal and permitting the molten metal to move downwardly through the mold to form an ingot, and simultaneously chilling the ingot by spraying coolant on the ingot from the coolant delivery system is provided.
摘要翻译：本发明公开了一种用于金属的直接冷硬铸造的设备，包括由具有上端和下端的铸造表面形成的开放式模腔，位于模腔上端的耐火套筒适于接收熔融金属用于供应冷却剂以冷却下降的热金属体的冷却剂输送系统，以及安装在耐火套筒和模腔的周壁之间的氮化硼环。在另一个实施例中，用于金属的直接冷硬铸造的设备还包括落水管而不是位于模腔上端的耐火套管，该耐火套管适于接收具有流量控制棒或浮动挡板的熔融金属，控制棒控制熔融金属进入模腔的量。在另一个实施方案中，一种用于金属的直接冷硬铸造的方法包括以下步骤：用熔融金属连续地填充空腔的上端，并允许熔融金属向下移动通过铸模以形成铸锭，同时冷却提供了通过将冷却剂喷洒在来自冷却剂输送系统的锭块上的锭块。
