ferroalloy |
Also found in: Wikipedia | 0.04 sec. |
ferroalloyAlloy of iron (less than 50%) and one or more other metals, important as a source of various metallic elements in the production of alloy steels. The principal ferroalloys are ferromanganese, ferrochromium, ferromolybdenum, ferrotitanium, ferrovanadium, ferrosilicon, ferroboron, and ferrophosphorus. They usually have lower melting ranges than do the pure elements and can be incorporated more readily in the molten steel. Ferroalloys are prepared from charges of the nonferrous metal ore, iron or iron ore, coke or coal, and flux by treatment at high temperature in submerged-arc electric furnaces.
