摘要： During the production of non-stainless steel, slag containing a high proportion of metal oxides, primarily iron oxide, is formed during the smelting of the solid material in the electric arc furnace. The concentration of the iron oxide often reaches values of more than 20%. This slag has a poor foaming capability and does not permit the typical characteristics of a carbon steel slag to be achieved. In order to cause such a slag to foam, according to the invention it is proposed to load the electric arc furnace with pellets or briquettes (8) which consist of a defined mixture of an iron oxide carrier and an iron carrier as ballast material, of carbon as reducing agent and also of a binder material, which react in the electric arc furnace in a reducing manner, floating under the slag (7) in the steel melt (6). The reaction gases (12) produced in this way consist primarily of carbon monoxide and advantageously support the foaming of the slag.
摘要翻译：在非不锈钢的生产过程中，在电弧炉中固体材料的熔炼过程中形成了含有高比例金属氧化物，主要是氧化铁的炉渣。氧化铁的浓度通常达到超过20％的值。该渣具有差的发泡能力，不能实现碳钢渣的典型特征。为了使这样的炉渣发泡，根据本发明，提出了将电弧炉装载到由氧化铁载体和铁载体的限定混合物组成的颗粒或团块（8）作为压载材料，碳作为还原剂以及还原剂在电弧炉中以还原的方式反应，漂浮在钢熔体（6）内的炉渣（7）下方。以这种方式生产的反应气体（12）主要由一氧化碳组成，并有利地支持炉渣的起泡。
