AOD是原美国联碳公司、现美国普莱克斯实用气体公司的专利技术“氩氧脱碳制钢工艺”的简称。它是双炼工艺,先将废钢或原料在电弧炉或感应炉内熔化,然后在专门的AOD炉内脱碳和精炼。受控的氧、氩经下吹管吹入到熔融金属中进行脱碳,并使金属氧化物减至最少。在AOD炉中脱氧、脱硫并从渣中回收所需要的金属,在低合金钢时,还脱磷。在整个过程中,连续进行排气和均质化,从而生产出干净和均一的产品。AOD是美国联碳于1954年发明的,经过综合开发后,1968年由位于印第安纳州Ft．Wayne的Joslyn不锈钢厂开始工业生产。世界不锈钢工业很快认识到这种工艺能用便宜低质的原料,生产出高质量产品的能力。今天世界不锈钢总产量的 AOD is the original American Union Carbon Company, now the United States Praxair utility gas company’s patented technology “argon oxygen decarburization steel process” for short. It is a double-smelting process in which scrap or raw materials are first melted in an electric arc furnace or induction furnace and then decarburized and refined in a specialized AOD furnace. Controlled oxygen and argon are blown into the molten metal through the blow pipe to decarburize and minimize the metal oxides. Deoxidation in the AOD furnace, desulfurization and recovery of the required metal from the slag, low alloy steel, but also dephosphorization. Throughout the process, the exhaust and the homogenization are continuously carried out to produce a clean and uniform product. AOD was invented by Union Carbide in 1954 and was developed in 1968 by Ft, Indiana. Wayne’s Joslyn stainless steel plant started industrial production. The world’s stainless steel industry quickly realized that this process can produce cheap, low-quality raw materials and produce high-quality products. Today’s world stainless steel output
