摘要： An agent for desulfurization, dephosphorization, desiliconizing, and denitriding of ironmelt and melt containing chromium or manganese, consisting of at least one of the following mineral raw-material: alkali-containing plagioclase (feldspar), alkali-containing orthoclase, montmorillonite (perlite), bentonite, muscovite, or zeolithe, and calcium carbide and/or calcium oxide.These mixtures can be blended further with scale, Fe-ores, Cr-ores or Mn-ores and used by standard technologies. The mineralic components, in connection with calcium carbide, lime, iron-ore or scale or other related ores, cause an effective reduction of unwanted elements, such as sulfur, phosphorus, silicium, and nitrogen, in the metal melts.The slags produced are freely skimmed and contain less iron granules than standard agents. Some of these materials may be enriched with alkali oxides by sintering or melting with appropriate compounds, like soda ash.This invention also involves a process for the treatment of iron-, ferrochromium and ferromanganese melts, wherein the components of the agent are fed either pre-mixed or separately into the melt.
摘要翻译：由以下矿物原料：含碱性斜长石（长石），含碱性正电岩，蒙脱石（珍珠岩）中的至少一种组成的含铬或锰的铁熔体和熔体脱硫，脱磷，脱硅和脱氮的试剂，，膨润土，白云母或沸石，以及碳化钙和/或氧化钙。这些混合物可以进一步与垢，Fe矿石，Cr矿石或Mn矿石混合，并通过标准技术使用。与碳化钙，石灰，铁矿石或水垢或其他相关矿石有关的矿物成分有助于在金属熔体中有效地还原不需要的元素，如硫，磷，硅和氮。生产的炉渣可以自由脱脂，含有比标准物质少的铁颗粒。这些材料中的一些可以通过用合适的化合物如苏打灰烧结或熔化而富集碱金属氧化物。本发明还涉及一种处理铁，铬铁和锰铁熔体的方法，其中将试剂的组分以预混合或分别进料到熔体中。
