A METHOD FOR MANUFACTURING FERRO MOLYBDENUM ALLOY BRIQUETTE FROM THE MIXING POWDER OF MILL SCALE AND MOLYBDENUM OXIDE POWDER BY SOLID-GAS REACTION AND THE BRIQUETTE PRODUCTED BY THE METHOD

摘要

PURPOSE: Ferro molybdenum alloy briquette and a method of manufacturing ferro molybdenum alloy briquette from the mixed powder of mill scale and molybdenum oxide powder by solid-gas reaction are provided to reduce volatile loss of molybdenum oxide by manufacturing ferro molybdenum alloy power in a power state and lowering the temperature of a process in manufacturing ferro molybdenum alloy by hydrogen reduction. CONSTITUTION: A method of manufacturing ferro molybdenum alloy briquette from the mixed powder of mill scale and molybdenum oxide powder by solid-gas reaction comprises next steps. Mill scale used as a raw material is crushed to a range of 75-150m using ball mill and at the same time, is mixed with oxide molybdenum powder. Hydrogen reduction is made on the mixture at a first low temperature. Hydrogen reduction is continuously made on the mixture at a second high temperature. The ferro molybdenum alloy powder is cooled under hydrogen atmosphere. The ferro molybdenum alloy powder is mixed with wax(Kenolube P11) and is pressed.
