摘    要:采用光学显微镜研究了碱度对钒钛烧结矿显微结构的影响.研究表明:碱度由2.1提高到2.5,烧结矿中钛磁铁矿、铁酸钙与硅酸二钙含量增加,钛赤铁矿与玻璃质含量降低;骸晶状赤铁矿与包边结构减少,显微结构由斑状向交织熔蚀结构过渡;相应的烧结矿强度增加.碱度为2.5时,铁酸钙主要以柱状、针状形态存在,钛磁铁矿主要以他形粒状形态存在,钙钛矿主要呈十字形和他形晶形态存在.

关 键 词:烧结  钒钛磁铁矿  碱度  显微结构  烧结矿强度  铁酸钙  钙钛矿

Abstract:The influences of basicity on microstructure of vanadium-titanium magnetite sinter were studied by optical microscopy.The results showed that when basicity is increased from 2.1 to 2.5,the content of titanomagnetite,calcium ferrite and dicalcium silicate increase,but the content of titanohematite and glassiness decrease;The content of the skeletal hematite and the wrapping texture decrease,the structure of the sinter turns from porphyritic structure to interweaving corroded;the corresponding strength of the...
Keywords:sintering  vanadium-titanium magnetite  basicity  microstructure  sinter strength  calciumferrite  perovskite
