Ferro Molybdenum Chemical Composition

Smelting Method for Ferro Molybdenum

Ferro molybdenum is typically produced through the highly efficient and effective metal thermal method, ensuring optimal quality and performance.
The primary raw material for smelting ferro molybdenum is molybdenite (MoS2). Before smelting, molybdenum concentrate generally undergoes oxidative roasting in a multi-hearth furnace, producing roasted molybdenum concentrate with a refined sulfur content of less than 0.07%, ensuring purity and quality.
The sophisticated process of smelting ferro molybdenum employs the advanced external furnace method. This meticulously designed furnace, a cylindrical marvel resting on a sand base, is expertly lined with robust clay bricks. The charge composition includes high-grade ferrosilicon with 75% silicon content, complemented by a touch of aluminum granules acting as a potent reducing agent. The smelting process is initiated using a top ignition technique, where an igniter, chosen from saltpeter, aluminum, or magnesium shavings, is strategically placed on the charge surface to ensure vigorous ignition. Following this ignition, the process transitions into a phase of quiescence, allowing for the efficient tapping of slag and the careful removal of the furnace cylinder. The resulting ferro molybdenum ingots undergo a precise cooling regimen, first in a sand pit, followed by a water-cooled chamber, before being expertly crushed and refined to perfection. Achieving impressive metal recovery rates of 92% to 99%, recent years have seen the rise of oxygen molybdenum briquettes as a favored alternative to traditional ferro molybdenum in the ever-evolving steelmaking industry.
