inclusion flotation(Baffles, weirs, and dams have long been in use to increase steel residence time and promote inclusion flotation to the tundish slag. 为了延长钢水停留时间、促进夹杂物上浮到中间包渣中,缓冲板、双挡墙已使用了好长时间。)
nonmetallic inclusion floatation(The trial revealed that baffle boards increased the steel residence time and enhanced nonmetallic inclusion floatation. 试验显示:缓冲板提高了钢水停留时间,促进了非金属夹杂物上浮。)
