在乌拉托斯特冶金工厂进行了用氩气和工业纯氮在炉外处理钢液,研究了对钢质量的影响。在实验室和工业条件下对单元和多元金属进行吹入惰性气体冶炼。试验是在30kg感应炉碱性坩埚中进行的,氮气经过石英管从上部吹入或者经过多孔底塞砖从下部吹入,通入氮气量为1～4M~3/T。钢中含氮量由EA—1
The steelwork was treated outside the furnace with argon and industrial pure nitrogen at the Ultust Metallurgical Plant to investigate the effect on the quality of the steel. Unit and multicomponent metals are blown into inert gas smelters under laboratory and industrial conditions. The test was carried out in a 30 kg induction furnace alkaline crucible. Nitrogen gas was blown through the quartz tube from above or through the porous bottom plug brick. The amount of nitrogen introduced was 1 to 4 M ~ 3 / T. Steel nitrogen content by EA-1
