连铸保护渣结晶体和玻璃体密度的研究黄青云王谦何生平青雪梅（重庆大学材料科学与工程学院，重庆400044）摘要：研究了可析出枪晶石矿相的CSF渣系和析出屑石矿相的CTS渣系在冷凝后渣中结晶体和玻璃体密度的差异，得到以下结论：(1)在保护渣的玻璃体向结晶体的转化过程中，出现了体积膨胀与体积收缩两种现象；(2)保护渣的结晶性能与凝固收缩情况密切相关；(3)析晶过程中保护渣的体积变化可能受晶粒大小及气孔影响。关键词：保护渣枪晶石屑石结晶体玻璃体密度StudyontheDensitybetweenCrystalandGlassyofContinuousCastingMouldFluxesHUANGQingyun,WANGQian,HEShengping,QINGXuemei(CollegeofMaterialsScienceandEngineeringofChongqingUniversity,Chongqing400044,China)Abstract:ThedifferenceondensitybetweencrystalandglassyofcuspidineinCaO-SiO2-CaF2slagandCaOSiO2TiO2inCaO-SiO2-TiO2slagduringcondensationhasbeenstudied.Thecomparisonindensitybetweencrystalandglassydemonstratedthat:(1)Therearetwophenomena,e.g.,thevolumeincreaseandvolumecontraction,whenglassyofmouldfluxchangesintocrystal;(2)Thecrystalperformanceofmouldfluxesiscontactwithcontractio..
