    摘要： A plug comprises a refractory body having a plurality of gas passgeways through which gas is blown into a refining apparatus. Each gas passageway may be defined by at least two metal tubes which are longitudinally spaced apart from each other. Alternatively, each gas passageway may be at least partly defined by an electrically insulating tube. The plug may alternatively have a plurality of gas passageways each having a bare refractory wall, while the body is reinforced with nonconductive mineral fibers, or metal wires which do not continuously extend throughout the plug. The plug may further be provided with a plurality of elongated holes extending in parallel to the gas passgeways from the inner surface of the body facing the interior of the refining apparatus to an intermediate portion thereof.

    摘要翻译： 塞子包括具有多个气体通道的耐火体，气体通过该气体通道吹入精炼装置。 每个气体通道可以由彼此纵向间隔开的至少两个金属管限定。 或者，每个气体通道可以至少部分地由电绝缘管限定。 插头可以替代地具有多个气体通道，每个气体通道具有裸露的耐火壁，而主体用不导电的矿物纤维或不贯穿整个插塞的金属线增强。 插头还可以设置有多个细长孔，其平行于气体通道从主体的内表面朝向精炼装置的内部延伸到其中间部分。
