一,KALDO法的简要发展历史纯氧炼钢法包括KALDO法、LD法及Rotor法等三种方法,这些方法是在第二次世界大战后才得到迅速发展的。由于这些炼钢法都是以纯氧做主要的精炼剂,所以称为纯氧炼钢法。虽然它们都使用氧气,但因氧气的导入方法不同,精炼反应有显著差异,所以其名称也各不相同。距今107年前,发明贝斯麦转炉的H.Bessemer就 A Brief History of the KALDO Law The history of pure oxygen steelmaking includes the KALDO, LD and Rotor methods, which were developed rapidly after the Second World War. Because these steelmaking methods are pure oxygen as the main refining agent, so called pure oxygen steelmaking method. Although all of them use oxygen, their names vary depending on how oxygen is introduced and the refining reaction is significantly different. About 107 years ago, H. Bessemer invented the Bessie converter
