    摘要： A two-stage orifice outlet is provided for an electric furnace. The structure defining the inner orifice adjacent the interior of the furnace through which molten material passes in its initial stages of withdrawal from the furnace is made of a refractory metal to withstand the high temperatures present within the furnace and this refractory metal must be protected from the oxidizing effects of air. The outer structure defining the outer orifice is made from a more oxidation resistant material and acts as a shield to prevent the oxidation of the refractory metal inner orifice. The outer orifice is maintained below a temperature at which it will undergo rapid deterioration by the use of cooling means. The outlet described above is operated without injecting neutral or reducing gases into the area surrounding the furnace outlet as was required by prior art furnaces of this type.

    摘要翻译： 为电炉提供两级孔口。 限定靠近炉内部的内孔的结构，熔融材料在其从炉中退出的初始阶段通过的内部孔由难熔金属制成，以承受炉内存在的高温，并且该难熔金属必须被保护免受 空气的氧化作用。 限定外部孔口的外部结构由更耐氧化的材料制成并用作防护层以防止难熔金属内部孔口的氧化。 外孔保持在使用冷却装置将会经历快速劣化的温度以下。 上述出口是在没有将中性或还原性气体注入炉出口周围的区域的情况下操作的，如现有技术的这种炉子所要求的那样。

    摘要： High-temperature melting furnace comprising a vessel having a molten product extracting means surrounded by melting electrodes. A ceramic refractory lining covers the inner face of the vessel. Sealing means are provided for sealing off the whole of the face of the vessel from the exterior. Means are also provided for constantly blowing in a region located at the bottom of the vessel a small amount of inert gas into the lining which opposes penetration into the lining of gases liable to attack the metal of the support of the extracting means and the metal of the electrode rods in contact with the lining.
