1982年8月EOF法第一次被提出,意思是“最佳用能的炉子”(Energy opfi-mizing iurnace)。平炉上使用这种技术时,在熔池表面下水平吹氧,从1978年起就在15～250吨容量的平炉上有效地应用。熔池下吹氧也是EOF法的一个主要特点。
August 1982 EOF method was first proposed, which means “energy-saving stove” (Energy opfi-mizing iurnace). When using this technique on open hearths, oxygen is blown horizontally below the bath surface and has been used effectively on open hearth furnaces with capacity of 15 to 250 tons since 1978. Oxygen blowing pool is also a major feature of the EOF method.
