You will find good papers as resources, you can download and discuses with me or friends. And having an overview for submerged arc furnaces design and operations. It is attended for Engineers working in this field, and students or metallurgists maybe find answers for their questions, because at the end of this course you will figure out that you have a preview for this manufacture and the main problems and solutions for the ferrosilicon production process. The steelmaking industry is the only consumer.
Si-Mn alloy grades are medium carbon (MC) and low carbon (LC). A standard Si-Mn alloy contains 65 to 70 Mn, 15 to 20 Si and 1.5 to 2 C. The aim of this course is to present the basic principles for the production of ferrosilicon alloys processes, and a simple preview for submerged arc furnaces. Silico-manganese (Si-Mn) is an alloy used for adding both silicon (Si) and manganese (Mn) to liquid steel during steelmaking at low carbon (C) content. Raw materials are perhaps the most important factor for obtaining good furnace operation the first step towards improvements is to reduce the variations The smelting of ferroalloys is commonly performed in electric arc furnaces.Īlthough ferromanganese can be produced in a blast furnace in a manner similar to iron, the reduction of chromium and silicon from their oxides requires higher Process temperatures and lower oxygen potentials than can be achieved in a blast furnace This work presents computations of alternating electric current distributions inside an industrial submerged arc furnace for silicon production. It is important to have Consistency in alloying element amounts in ferroalloys from heat to heat, allowing the manufacture of standard products The main indicator of the quality of a ferroalloy is its chemical composition and, above all, the content of the leading element. (ii) lack of sensitivity to electrode movement. Bureau of Mines defines ferroalloy as an alloy of iron with at least one other element except for carbon. (i) dead and live phases (fairlywell known in open-arc furnaces).
Ferroalloys, by definition, are alloys of two or more metals, of which one is Iron.
