PREPARATION METHOD FOR HIGH-VANADIUM HIGH-CHROMIUM TYPE VANADIUM TITANIUM MAGNETITE PELLETS

摘要

A preparation method for high-vanadium high-chromium type vanadium titanium magnetite pellets, comprising: performing wet-grinding on the imported high-vanadium high-chromium type vanadium titanium magnetite; compounding according to the pellet raw material ratio; drying and mixing the raw materials; adding bottom water for material mixing; braising the materials; pelletizing; screening fresh pellets to obtain 8-16 mm fresh pellets; and then drying and preoxidizing, shaft furnace roasting and cooling to prepare the high-vanadium high-chromium type vanadium titanium magnetite pellets.
