前言锰铁合金通常是用埋弧电炉炼成的。这些炉子是使用三根炭素或石墨电极的三相型。电极伸入填充在炉子上部的炉料。电弧埋没于炉料内,废气从疏松的炉料中逸出。埋弧电炉对于铁合金冶炼来说是一种得到验证的高效率装置,但也存在某些缺点。 Preface Ferromanganese is usually made from a submerged arc furnace. These furnaces are three-phase models that use three carbon or graphite electrodes. The electrode extends into the charge filling the upper part of the furnace. The arc is buried in the charge and the exhaust gas escapes from the loose charge. Submerged arc furnaces are a proven and efficient device for iron alloy smelting, but also have certain disadvantages.
