METHOD FOR PREPARING FERROMOLYBDENUM ALLOY BRIQUETTE FROM POWDER MIXTURE OF MILL SCALE AND MOLYBDENUM OXIDE POWDER THROUGH SOLID-GAS REACTION, AND BRIQUETTE PREPARED BY SAME

摘要

The present invention relates to a method for preparing a ferromolybdenum alloy in a briquette form, wherein the ferromolybdenum alloy is used for adjusting ingredients of a melt in a steelmaking process for manufacturing special steel. More particularly, the present invention relates to a method for preparing a ferromolybdenum alloy briquette, and a briquette prepared by same, wherein the ferromolybdenum alloy briquette is obtained by: mixing mill scale (mixture of Fe, FeO, and Fe₂O₃) powders discharged from a steel forging process as an iron raw material and molybdenum oxide (MoO₃) powders as a molybdenum raw material; reducing this mixture in a powdery state using a hydrogen gas; mixing the prepared ferromolybdenum alloy powders and wax and press-molding the resulting mixture; sintering the press-molded mixture at a high temperature in a hydrogen gas atmosphere; and then cooling down the sintered mixture to prepare a ferromolybdenum alloy in a briquette form.
