porous plug
met. 多孔塞; 透气塞; 透气砖; 供气砖 (【技】供炼钢生产使用的一种供气元件,亦称透气砖。一般分为两大类:安置于钢包底部,用于吹氩或吹氮精炼的供气砖,或安置于顶底复吹转炉底部,用于吹氩气的供气耐火部件。供气砖一般具有特殊设计的气孔通道,以保证气体的有效通过,同时防止铁水或钢水的反渗透。供气砖应具有稳定的结构、优良的抗侵蚀能力和抗剥落能力。供气砖所使用的材料主要有刚玉质、镁碳质、镁尖晶石质和镁铬质等。: ① During reheating the bath is continually stirred by means of inert gas supplied via a porous plug in the ladle bottom. 在加热过程中通过钢包底部多孔塞喷吹惰性气体使钢水熔池受到持续搅拌。② An inductively stirred bath is shown in Fig. 3-15 (a) while in Fig. 3-15 (b) the bath is stirred by bubbling argon through a porous plug located in the ladle bottom. 图3-15 (a) 为感应搅拌的钢水熔池,而图 3-15 (b) 为通过钢包底部多孔塞吹氩搅拌的钢水熔池。)
