摘要： A multistage electromagnetic purification method of molten metal, which employs a multistage separator composed of two or more multichannel straight-pass separators bonded together with inorganic high-temperature adhesive. Each stage of the separators is set up in such a manner that the region of centerline of each channel in the former separators is occupied by the sidewall of the next separators at the corresponding position therein; while simultaneously the position in the next separators becomes a region close to sidewall. The multistage separator eliminates the “dead zone” of electromagnetic separation, realizes the transformation from “weak zone” to “strong zone” of electromagnetic separation, and significantly increases removal efficiency of inclusions in the melt with great volume under the effect of induced magnetic field.

摘要： The present invention concerns a multistage-electromagnetic purification method of molten metal, which relates to the field of casting technique. The method of present invention employs a multistage separator instead of a single-stage one. The multistage separator is composed of two or more multichannel straight-pass separators bonded together with inorganic high-temperature adhesive. Each stage of the separators should be set up in such a manner that the region of centerline of each channel in the former separator is occupied by the sidewall of the next separator at the corresponding position therein, simultaneously the position in the next separator, which is corresponding to the central region of the channel in former separator, becomes a region close to sidewall. By applying multistage separator instead of single-stage separator, the present invention could eliminate the “dead zone” of electromagnetic separation, realize the transformation from “weak zone” to “strong zone” of electromagnetic separation, and increase significantly the removing efficiency of inclusions in the melt with great volume under the effect of induced magnetic field.

摘要翻译： 本发明涉及熔融金属的多级电磁净化方法，其涉及铸造技术领域。 本发明的方法采用多级分离器而不是单级分离器。 多级分离器由两种或多种与无机高温粘合剂结合在一起的多通道直通分离器组成。 分离器的每个阶段应该被设置成使得前一个分离器中的每个通道的中心线的区域在其中的相应位置处被下一个分离器的侧壁占据，同时在下一个分离器中的位置 对应于前分离器中的通道的中心区域，成为靠近侧壁的区域。 通过应用多级分离器代替单级分离器，本发明可以消除电磁分离的“死区”，实现电磁分离的“弱区”到“强区”的转变，大大提高了夹杂物的去除效率 在熔体体积大的情况下，在感应磁场的作用下。
