在１５００℃，感应炉熔炼的铸铁中吹入氧气和二氧化碳气，在铁液中氮含量为０．０１７％的条件下，能有效脱氮，分别在５ｍｉｎ和２０ｍｉｎ内使氮含量下降到０．００４％．
At 1500 ℃, oxygen and carbon dioxide gas were blown into the cast iron melted by the induction furnace. The nitrogen content in the molten iron was 0.017%, which could effectively denitrify the nitrogen content to 0 in 5min and 20min, respectively. 004%.
