The viscosity of 24 melts of different composition, containing not less than 60% CaF_2 and not more than 40%(CaO+La_2O_3), has been determined, and the phase characteristics of these melts under different solidification regimes has been investigated by petrography, EPMA and X-ray structural analysis.

对配料中CaF_2不低于60％，(CaO+La_2O_3)不高于40％的24组不同配料成分的熔渣的粘度进行了测定。研究了这类熔渣在不同冷凝制度下的物相特征。

In the condition of keeping F、 K、Na content fixed, To improve slag structure and raise slag melting point and viscosity, MgO content is raised and TiO〓 is added. the main content is as follows:(1) Keeping CaO/SiO〓 fixed, MgO content rises from 10% to 16%, the free running temperature goes up 106℃, the viscosity goe down at bigger than 1425℃, but difference is little; keeping /SiO〓 fixed, MgO content rises from 10% to 16%, the free running temperature rises 87℃, the viscosity rises too; adding TiO〓 to 5%, the free running temperature goes up 98℃, the viscosity rise a little.(2) Powder crystal x ray diffraction and microscopic analysis shows: increasing MgO content, the cuspidine will decreace or even disappear, the monticellite goes up with MgO content rising, keeping /SiO〓 fixed, Akermanite content goes up, for high melting point minerals appear or go up, the free running temperature of the slag bearing F is raised; Adding TiO〓, high melting point mineral—Perovskite forms, it can making other minerals'crystalling fast, it is the reason that TiO〓 raises the free running temperature of the slag bearing F.

2对测定粘度的冷凝渣所进行的X粉晶衍射及显微分析和鉴定表明，增加MgO含量，渣中枪晶石将减少甚至消失，而钙镁橄榄石则随MgO含量增加而增加，在／SiO〓不变时，黄长石含量也有所增加，高熔点矿物的出现和增加，提高了含氟熔渣的熔化性温度；加入TiO〓熔渣中将形成高熔点矿物-钙钛矿，钙钛矿的形成还促使黄长石的结晶，这是TiO〓提高含氟熔渣熔化性温度的根本原因。

And the denaturization"s melting property is better than the former one, then it"s propitious to denaturize the final slag quickly.

并且其熔化性优于原改质剂，有利于对终渣快速改质，保证了改质后熔渣的均匀性，有利予溅渣护炉效果的提高。

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。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.
