摘要
本文综述了金属液熔渣脱氮、真空脱氮和气泡携带法脱氮方法。熔渣脱氮热力学研究主要涉及脱氮反应和熔渣的氮容量。真空度、氢气搅拌和金属液中氧、硫浓度是影响真空脱氮和气泡携带法脱氮的主要因素。
The methods of denitrogenation from liquid metal by flux, vacuum and bubble carrying are reviewed in this paper. Main studies in the field of thermodynamics of denitrogenation by flux are related to the chemical reactions of nitrogen in slag and metal and the nitride capacity of slag.Vacuum denitrogenation and bubble carrying denitrogenation are mainly influenced by vacuum,argon stirring, oxygen and sulphur concentrations in liquid metal.
