摘要
采用特殊结构的镁芯包芯线对钢水进行处理,处理过程比采用普通结构含镁包芯线平稳,镁可以有效地加入钢水中,并获得比较稳定的收得率.经过镁处理后,钢中夹杂物类型、形态和尺寸明显变化.大尺寸的Al2O3夹杂转变为细小的MgO·Al2O3,同时使钢中Al2O3·MnS夹杂以细小的Al2O3·MnS·MgS的形式存在.
The process of Mg-cored wire feeding was investigated. The Mg cored wire with special structure was applied in inclusion modification in steel. The process of feeding the Mg-cored wire is more smoothly than feeding the Mg-wire with old structure in steel treating at 1600°C, the absorption ratio is higher and more stable than that of the old process. After being treated by Mg-cored wire feeding, the Al2O3 inclusions with the big size changes to the fine particles of MgO?Al2O3 inclusions. At same time, the Al2O3?MnS inclusions changes to the Al2O3?MgS?MnS inclusions.
