A Novel Type Refractories Used as Linings of Vanadium-Extraction Converter
Based on studying the wear mechanism of MgO-C bricks used as linings of vanadium-extraction converters,a novel type of MgO-Fe-C bricks was developed and used as linings of vanadium-extraction converters,and its properties were investigated by comparing to the traditional MgO-C bricks.The results showed that the poor service life of MgO-C bricks was caused by the poor erosion influence of the oxidized layer due to the poor sinterability,whereas the oxidized layer of MgO-Fe-C bricks was well sintered by the oxidation of Fe phase.The static and rotating slag corrosion tests showed that there was no difference in species of the slag permeating into the two kinds of bricks,and the significant improvement of slag corrosion resistance was due to the promotion of the sinterability and modification of the microstructure.It is considered that MgO-Fe-C brick is a favorable substitute of MgO-C refractory to be used as linings of vanadium-extraction converters.
