porous insert(Prior to transfer to the caster, steel is normally processed through a ladle metallurgy unit which has the capability for scrap cooling, alloying, and temperature and composition homogenization by argon bubbling through a porous insert in the bottom of the ladle. 在钢水转运到连铸机前，通常要经过钢包冶金设备进行处理。钢包冶金设备具有加废钢降温、合金化和通过安装在钢包底部多孔塞喷吹氩气泡使钢水温度与成分均匀化的功能。)
porous refractory lining(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。)
porous stirring plug(The ladle is positioned such that the snorkel is situated right above the porous stirring plug, Fig. 3-23.如图 3-23 所示，钢包的放置应使隔离罩正好位于多孔搅拌塞的上方。)
