Design and Application of Blast Furnace Casthouse Refractory for Smelting Vanadium-bearing Titaniferous Magnetite

Properties of blast furnace slag from vanadium-bearing titaniferous magnetite smelting is investigated.The damage mechanism of the dry-out rammed mixture for iron runner is analyzed and influence of the sintering and anti-adhesion compound additive on the performance of the rammed mixture is probed.The results show that appropriate amount of compound additives can improve the strength and slagging resistance of material.The newly designed dry-out rammed mixture for the runner has efficiently resolved the problems of slag sticking,which prolongs the service life to 7~9 days from 3~5 days.
