When different materials mixed,the mixture will have a mixed melting point of mixture ,and the mixed melting point of mixture is different from the intersoluble solutions.we separate the intersoluble solutions by different melting piont of intersoluble solutions when separate temperature is flexible temperatureThese intersoluble solutions different in melting point, the method would make the high melting point material became solid while the low melting point material still be liquid by adopting cryogenic treatment with stirring so as to meet the requirement of purifying these two solutions.

这种分离方法的特点是利用两种互溶性物质具有不同的熔点，通过低温处理，并同时加以搅拌，震荡，使高熔点物质和低熔点物质形成固液混合体，再对固液混合体进行离心分离得到高熔点的固体和低熔点的液体，从而达到浓缩、提纯两种物质目的。

An investigation to the microstructure of worn sample of dry vibratable materials for tundish working lining after using 40 hours shows that the materials changes the properties of slag by the chemical filter, increases the viscosity of slag, forms a dense layer at slag/refactories interface, then blocks the more slag penetrate in it. The complex phase formed at the interface, such as magnesiowusite and complex spinel et al, would absorb in more low-melting point minerals, then degrade its melting point and dissolve into slag, which forms low-melting point silicate phase, penetrates into dry vibratable materials along with Monticellite and Merwinite bonding phase by diffusion.

根据使用40小时后的中间包工作层残衬结构分析，其侵蚀机理为：干式料对渗入熔渣产生化学过滤作用，增大熔渣粘度，在干式料/熔渣界面形成致密结构，阻碍熔渣的进一步渗透；随着反应的进行复合矿物中熔剂含量的增多，熔点降低，溶于熔渣形成低熔点的硅酸盐相，并沿着干式料中的钙镁橄榄石和镁蔷薇辉石等结合相向干式料基质中扩散渗透。
