锰矿应当把它看作是一种综合性的原料,因为它不仅含有锰,还含其它有价值的金属——硅,铝及钙等。如将贫锰完全还原,可炼得硅锰铝或硅锰钙铝合金。哈萨克斯坦科学院化冶研究所与耶尔马克夫斯克铁合金厂共同试验用中哈萨克斯坦的锰矿炼制硅锰铝合金。与此同时还试验了其它两个产地的锰矿。自1982年以来进行了三次硅锰铝合金的试炼:甲、用能力为1000KVA 三相电炉,电极直径为250mm;乙、用能力为1000KVA 单相电炉,电极直径为700mm;丙、用能力
Manganese ore should be regarded as a comprehensive raw material, because it contains not only manganese, but also other valuable metals - silicon, aluminum and calcium. Such as the poor manganese completely restored, can be refined silicomanganese or silicon manganese calcium aluminum alloy. Kazakhstan Institute of Chemistry and Metallurgy Institute and Yermakovske ferroalloy plant jointly test the use of Kazakhstan’s manganese ore refining Si-Mn alloy. At the same time also tested the other two manganese origin. Three trials of Si-Mn-Al alloy have been conducted since 1982: A, with a capacity of 1000KVA three-phase electric furnace, electrode diameter of 250mm; B, with a capacity of 1000KVA single-phase electric furnace, electrode diameter of 700mm;
