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。
