    摘要： There is provided a process for producing a high-manganese iron alloy from a manganese ore and/or a pre-reduced product thereof in a top and bottom blown converter type reaction vessel holding molten iron or a molten manganese iron alloy, together with a molten slag, said molten iron or alloy and said molten slag being the products of a separate smelting furnace, gas being blown into said vessel through a bottom blowing nozzle, said process comprising charging said vessel with a supply of raw materials including at least one source of manganese and iron selected from a manganese ore containing manganese oxide and iron oxide and a pre-reduced product thereof, a solid carbonaceous substance and a slag forming agent, while simultaneously blowing gas selected from oxygen and a gas containing oxygen into said vessel through a top blowing lance to burn said carbonaceous substance so as to heat, melt and reduce said raw materials to form a melt containing manganese oxide and iron oxide; supplying an additional carbonaceous substance into said melt to reduce said manganese oxide and said iron oxide to form a molten high-manganese iron alloy and a molten slag, discontinuing said blowing of gas through said top blowing lance, and removing said molten high-manganese iron alloy and said molten slag from said vessel, said molten alloy being used for casting.

    摘要翻译： 本发明提供一种在含有铁水或熔融锰铁合金的顶部和底部转化型反应容器中从锰矿石和/或其预还原产物生产高锰铁合金的方法，以及熔融 熔渣，所述熔融铁或合金，所述熔融炉渣是单独熔炼炉的产物，气体通过底吹喷嘴吹入所述容器中，所述方法包括向原料供应原料，该原料包括至少一种 选自含有锰氧化物和氧化铁的锰矿及其预还原产物，固体碳质物质和成渣剂的锰和铁，同时通过顶部将从氧气和含氧气体中选出的气体吹入所述容器中 吹枪吹烧所述碳质物质，以加热，熔化和还原所述原料以形成含有氧化锰和氧化铁的熔体; 向所述熔体中提供另外的碳质物质以减少所述氧化锰和所述氧化铁以形成熔融的高锰铁合金和熔渣，停止通过所述顶吹喷枪吹入气体，并且除去所述熔融的高锰铁 合金和来自所述容器的所述熔渣，所述熔融合金用于铸造。
