铁合金的生产
摘要：
本发明公开了一种在电弧炉中生产铁合金的方法，所述方法包括用未结块的含碳聚合物装料所述炉的步骤，使得所述聚合物起熔渣起泡剂的作用。本发明还涉及未结块的含碳聚合物在电弧炉中的铁合金生产中作为熔渣起泡剂的用途。本发明还公开了一种在电弧炉中生产铁合金的方法，包括用铁合金原料装料所述炉；将在炉中的原料加热至熔融状态并且在合金/原料的熔融表面上形成熔渣；和用起熔渣起泡剂作用的未结块的含碳聚合物装料所述炉。此外，本发明还涉及确定含碳聚合物在使用含碳原料的生产铁合金的炉中的再循环性的系统。
摘要（英）：

A method for producing a ferro-alloy in an electric arc furnace is disclosed. The method comprises the step of charging the furnace with an un-agglomerated carbon-containing polymer such that the polymer functions as a slag foaming agent. The present invention also relates to the use of an un-agglomerated carbon-containing polymer as a slag foaming agent in the production of a ferro-alloy in an electric arc furnace. The present invention also discloses a method for producing a ferro-alloy in an electric arc furnace, comprising the steps of: charging the furnace with feedstock for the ferro-alloy; heating the feedstock in the furnace to a molten state and to form a slag on a molten surface of the alloy/feedstock; and charging the furnace with an un-agglomerated carbon-containing polymer that functions as a slag foaming agent. In addition, the present invention also relates to a system for determining the recyclability of a carbon-containing polymer in a ferro-alloy production furnace that employs a carbon-containing feedstock.
