摘要： Exemplary embodiments of the invention provide a casting apparatus for continuously casting a metal strip article (e.g. a twin-belt metal caster or a twin-block metal caster). The apparatus has a casting cavity defined between a pair of moving elongated opposed casting surfaces, and the casting cavity has an entrance and an exit aligned in a direction of casting. The casting cavity is also provided with a molten metal injector at its entrance, the injector having an internal metal channel including a downstream opening for introducing molten metal into the casting cavity, and a pair of side dams at each lateral side of the casting cavity for confining molten metal from the injector within the cavity. At least one of the side dams comprises an elongated element that is movable laterally relative to the direction of casting during a casting operation. The elongated element extends in the direction of casting from the injector longitudinally between the casting surfaces at least to a downstream position within the casting cavity where the metal adjacent the element is laterally self-supporting.

摘要： Exemplary embodiments of the invention provide a side dam for a continuous metal casting apparatus having elongated opposed casting surfaces forming a casting cavity. The side dam has an elongated upstream part and an elongated downstream part that are mutually laterally pivotable, and a smooth metal-contacting side surface extending continuously from an upstream end to a downstream end of the side dam. The surface has regions thereof formed on the upstream part and the downstream part. Mutual pivoting of the upstream part and the downstream part of the side dam enables the regions of the smooth metal-contacting side surface to be moved out of mutual coplanar alignment. The side dams can therefore be used to form either a convergent or divergent casting cavity to assists the casting procedure and to enhance the properties of the cast article.
摘要翻译：本发明的示例性实施例提供了一种用于连续金属铸造装置的侧坝，其具有形成铸造腔的细长的相对的铸造表面。侧坝具有细长的上游部分和细长的下游部分，其相互横向枢转，以及从侧坝的上游端到下游端连续延伸的平滑的金属接触侧表面。该表面具有形成在上游部分和下游部分上的区域。侧坝的上游部分和下游部分的相互枢转使得光滑的金属接触侧表面的区域能够移出相互共面对准。因此，侧坝可以用于形成会聚或分散的铸造腔，以帮助铸造过程并增强铸造制品的性能。

摘要： Exemplary embodiments of the invention relate to a side dam block for a continuous metal caster apparatus. The block comprises a body of molten metal resistant material having a metal-contacting surface. The metal contacting surface has a plurality of indentations therein, the indentations having openings at the metal-contacting surface dimensioned to prevent penetration of molten metal into the indentations under casting conditions. Due to a smaller area of direct contact between the molten metal and the surfaces of the blocks, the blocks extract less heat from the molten metal than conventional blocks and help to reduce so-called "dog-bone" and "sink" type deformation of the cast article.
摘要翻译：本发明的示例性实施例涉及一种用于连续金属脚轮装置的侧坝块。该块包括具有金属接触表面的熔融金属材料体。金属接触面在其中具有多个凹陷，凹陷在金属接触表面处具有开口，其尺寸设计成防止熔融金属在铸造条件下渗透到凹陷中。由于熔融金属和块体表面之间的直接接触面积较小，因此块体比熔融金属块从传统块体中提取较少的热量，有助于减少所谓的“狗骨”和“下沉”型变形铸造文章。
