<\/p>\nThe multipurpose smelting\u00a0 unit\u00a0 MAGMA can\u00a0 be\u00a0 efficiently used\u00a0 in non-ferrous\u00a0 metallurgy instead\u00a0 of\u00a0 conventional\u00a0 units:\u00a0 Shaft\u00a0 furnace, Vanyukov furnace, Ausmelt unit, unit for fuming in the production of ni, cu, pb, sn, etc.<\/p>\n
Thanks to design peculiarities and high cumulative thermal efficiency, MAGMA provides better technical and economic performance.<\/p>\n
<\/p>\n
Continuous smelting of ferro-nickel with the use of MAGMA envisages preliminary heating of nickel ore and flux by process gases from the smelting chamber of the unit.<\/p>\n
Fed materials are smelted in a liquid bath of ore-flux molten mass. For liquid-phase reduction of nickel, cobalt and some part of iron, carbon reducer is used that is fed to the surface of the molten mass.<\/p>\n
The smelting chamber of MAGMA is heated by fuel-oxygen burners \/ oxygen burners located on the perimeter of the body of the smelting chamber.<\/p>\n
The dust\u00a0 captured by the\u00a0 gas\u00a0 treatment system\u00a0 is injected\u00a0 in the flow of\u00a0 heated nitrogen into\u00a0 the\u00a0 ore-flux molten\u00a0 mass,\u00a0 where\u00a0 nickel and cobalt are additionally reduced from the dust.<\/p>\n
The produced ferro-nickel is also released from the smelting chamber non-continuously.<\/p>\n
The depleted reduced slag not containing oxides of nickel and cobalt is continuously released from the smelting unit.<\/p>\n
Further, after settlement and sedimentation of ferro-nickel prills, the slag is used for production of cast-slag products or slag crushed stones.<\/p>\n
Production capacity of MAGMA for smelted charge material is 300,000 tons per year.<\/p>\n
