Abstract
Ferro-molybdenum alloys are widely used in the production of heat-resistant stainless steel, acid-proof, tool steels. They give an uniform grain size, increase the tenderness, etc. Imported in the iron, molybdenum increases the hardness, the elasticity and the durability. FeMo is not produced in Bulgaria. The need of this ferro-alloy is covered by imports, which significantly increases the cost of the production. In this aspect, it is of an great interest the evaluation of the profitability of the organization at such proceedings in the country, based on the imported concentrate of MoO3, defining the necessary quantities of raw materials, technological operations, material flows and machines for a set annual production of FeMo60. The relative fuel charge materials is calculated based on the composed material and heat balance models of metal heat outside furnace production of ferro-molybdenum with an use of both aluminum and ferrosilicon as a gear. The technical and economic feasibility of profitable production is examined. The necessary raw materials for an annual production, both the daily and the hourly average and the one for the combustion furnace hearth are determined. A block diagram of a small factory, a sample processing of raw materials and necessary equipment are proposed.
