前言铁合金工业在美国称之为三大冶炼部门之一(钢铁、炼铝、铁合金),大部分铁合金产品是用电炉冶炼的,并要消耗大量电能,在冶炼过程中有大量的热能伴随着炉气排放到大气中。若能回收,将是一笔巨大的财富,为此早在三十年代就已引起世界各国的重视,到目前已取得了很大的发 Introduction Ferroalloy industry in the United States as one of the three major smelting departments (steel, aluminum, ferroalloy), most of the ferroalloy products are smelting furnace, and to consume large amounts of electricity, the smelting process with a lot of heat along with the furnace Exhaust gas into the atmosphere. If it can be recycled, it will be a tremendous asset. As early as the 1930s, it has attracted the attention of all countries in the world. So far, great achievements have been made
