摘要
研究了送风湿度对冲天炉熔炼铁水氢氧氮含量的影响,检测了铁水中溶解氧含量的变化。铁水中氢、氧气体含量随空气湿度升高而显著增多,而含氮量基本不变。铁水含氧量增高主要是化合氧(氧化物中的氧)增多,而对溶解氧无影响。
The influence of the blast humidity on the gas contents (hydrogen, oxygen and nitrogen) of molten iron in the cupola melting process has been investigated and the variation of oxygen content dissolved in the melt was measured. The hydrogen and oxygen contents in the molten iron markedly increased with blast humidity, while the nitrogen content had nearly no detectable change. The rising of the oxygen content is mainly due to the increase of oxide inclusions.
