aluminothermic reaction in ferrochrome production

SOME ASPECTS OF THE PRODUCTION OF FERROCHROME .The production of ferrochrome metal from chromite ores using a carbonaceous reductant reduces oxides to metal in order of reactivity. The main reactions involved in the reduction of iron, chromium and silicon to the metal phase are briefly presented below form). ...aluminothermic reaction in ferrochrome productionAluminothermic reactions are exothermic chemical reactions using aluminium as the reducing agent at high temperature. The process is industrially useful for production of alloys of iron. The most prominent example is the thermite reaction between iron oxides and aluminium to produce iron itself:. Fe 2 O 3 + 2 Al → 2 Fe + Al 2 O 3.12.4 Ferroalloy Production - US EPAMixed alumino/silico thermal processing is used for producing ferromolybdenum and ferrotungsten. Although aluminum is more expensive than carbon or silicon, the products are purer. Low-carbon (LC) ferrochromium is typically produced by fusing chromium ore and lime in a furnace. A specified amount is then placed in a ladle (ladle No. 1).
