Study on Melting Rate of Metalized Pellets of Vanadium-bearing Titaniferous Magnetite

The effect of influencing factors including melting temperature,alkalinity,slag to iron ratio and metalizing rate on the melting rate of metalized pellet of vanadium-bearing titaniferous magnetite was studied. The results indicate that the melting rate increases with the increase of melting temperature, metalizing rate and slag to iron ratio,and there is a kind of linear relationship between metalizing rate and melting time under certain conditions. When the alkalinity approaches 1.1,the melting time is the shortest,which means the melting rate is comparatively fast. However,when the alkalinity is either too high or low,the melting time increases.
