Removal of nitrogen from iron. |
摘要 |
<p>A method of reducing the nitrogen content in iron and iron alloys comprises introducing hydrogen into the melt in the form of a gas or hydrogen compound in sufficient quantity and for a sufficient time to reduce the nitrogen content and subsequently treating the melt to reduce the hydrogen content. The hydrogen may be mixed with an inert gas to minimize the risk of explosion.</p> |
