bubbling of inert gas into tundish(【技】通过在中间包安装管状气体分配器、多孔透气砖等，将惰性气体均匀喷人中间包，可有效改善钢水在中间包内的流动状态，促进夹杂物上浮并在液面形成保护层。: The bubbling of inert gas into the tundish via a porous refractory lining offers a potential means to enhance inclusion removal. 通过多孔耐火衬向中间包内喷人惰性气体是提高夹杂物去除能力的潜在方法。)
inert gas(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。)
inert gas stirring device(The ladle furnace is lined with a basic lining and equipped with inert gas stirring device, heating system and water-cooled roof. 这座钢包炉衬有碱性炉衬，装备有惰性气体搅拌装置、加热系统和水冷炉顶。)
