    摘要： Apparatus for injecting gas into molten metal includes a porous ceramic body having a first surface through which gas can be introduced into the body, and a second surface through which gas can flow from the body. A refractory member is attached to the body and surrounds at least the first surface, while leaving the second surface exposed. The refractory member is impervious to gas, while having a coefficient of thermal expansion approximating that of the body. Preferably, a refractory sealant securely attaches the refractory member to the body. By use of the present invention, the refractory member and the body remain tightly connected to each other at all times. Accordingly, gas leaks are prevented and all gas flowing into the body is discharged through the second surface, as desired.

    摘要翻译： 将气体注入熔融金属的装置包括具有第一表面的多孔陶瓷体，气体可以通过该第一表面被引入到主体中，以及第二表面，气体可以通过该第二表面从主体流出。 耐火构件附接到主体并且至少围绕第一表面，同时使第二表面暴露。 耐火构件不透气，同时热膨胀系数接近于身体的热膨胀系数。 优选地，耐火密封剂将耐火构件牢固地附接到主体。 通过使用本发明，耐火构件和主体始终保持彼此紧密连接。 因此，防止气体泄漏，并且根据需要，流入体内的所有气体通过第二表面排出。

    摘要： Techniques and apparatus for electromagnetically stirring a melt material are disclosed. In accordance with some embodiments, the system may include a containment vessel within which a melt material may be disposed. The melt material may include, for example, an electrically conductive alloy, which optionally may be non-ferromagnetic and/or glass-forming. In its molten state, the melt material may have alternating current (AC) applied directly thereto while being immersed in a magnetic field, which may be static or dynamic, depending on the desired stirring effect. Application of the AC and magnetic field may continue as the melt material cools and solidifies, the sinusoidal nature of the AC and the Lorentz force of the magnetic field providing convective motion which tends to agitate the molten melt material in a manner which may realize an improvement in heat transfer and chemical homogeneity of the resultant cast solid.
