PURPOSE: A ferroalloy manufacturing method is provided to prevent environmental pollution by preventing the generation of byproducts such as harmful gas, leachate, and slag, thereby omitting additional processes and facilities for treating by-products. CONSTITUTION: A ferroalloy manufacturing method is as follows: Molybdenum sulphide, iron oxide, and a reducing agent are prepared and are putted into an electric furnace. By controlling the atmosphere and the temperature of the electric furnace, the iron oxide is reduced to obtain Fe. The molybdenum sulphide is pyrolyzed to obtain Mo. The reaction between Fe and the Mo manufactures FeMo. [Reference numerals] (AA) Vacuum and pyrolysis process; (BB) Adding Fe_2 O_3 + carbon(C); (CC) MoS_2(raw ore); (DD) Mo(molybdenum) |
