Abstract

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 sinter is increasing.When basicity is 2.5,the form of calcium ferrite is stylolitic or acicular,the form of titanomagnetite is xenomorphic granular,the form of perovskite is crisscross or xenotopic.
