为了满足市场需求,通过提高入炉料批Mn/Fe比至8.5~9.0,控制熟料的配入量,矿热炉可直接生产出市场需求的高锰低硅锰硅合金(70.0%≤Mn≤71.5%、14.0%≤Si≤16.0%)。但生产过程中要注意正确的冶炼操作和选择合适的渣型。%In order to meet the needs of the market, by increasing the materials ration of Mn/Fe to 8.5~9.0 and controlling supplying amount of grog, the submerged arc furnace can produce high manganese and low silicon siliconmanganese (70.0%≤Mn≤71.5%、14.0%≤Si≤16.0%) to meet the needs of the market. It must pay attention to correct smelting operation and suitable type of slag selection.
