METHOD FOR FABRICATING HIGH-YIELD RATE MOO3 BRIQUETTE

摘要

PURPOSE: A method for fabricating a high-yield rate MoO3 briquette is provided to improve a yield rate of molybdenum by reducing an evaporation loss of MoO3 and increasing reduction speed of MoO3. CONSTITUTION: A mixture is fabricated by mixing a solidified slag with aluminum so as to reduce evaporation of MoO3 and promote reduction of MoO3 in such a manner that a yield rate of molybdenum in a molten steel is increased when manufacturing a molybdenum-added steel. The mixture includes the solidified slag of 5-60 wt.%, aluminum of 5 to 30 wt.%, binder of 1 to 5 wt.% and molybdenum. SiC and the solidified slag are added to MoO3 in order to reduce evaporation of MoO3, and to promote reduction of MoO3.
