電弧爐爐氣成分的影響因素

Influencing factors of EAF off-gas composition

  • 摘要: 為進一步完善對電弧爐爐氣成分變化規律的研究,本文分別對電弧爐爐氣中CO、CO2、O2和N2間的相互關系,以及電弧爐供氧流量、電弧爐熔池碳含量對電弧爐爐氣成分的影響進行實驗研究.結果表明,爐氣中CO在有大量CO2氣體存在下開始出現,并隨著CO2含量的增加而增加;O2與CO2、N2含量呈線性關系;O2與CO與呈指數關系;隨著供氧流量的提高,爐氣中CO和CO2的含量逐上升,O2和N2的含量降低,氧氣的利用率提高;當鋼水中碳質量分數為1.3%左右時,爐氣中CO、CO2含量達到最大.

     

    Abstract: The interrelations among CO,CO2,O2 and N2 in electric arc furnace (EAF) off-gas as well as the effects of oxygen flow and the pool's carbon content on EAF off-gas composition were investigated to perfect studies on the variation laws of EAF off-gas composition. The result shows CO appears under the existence of a lot of CO2,and its content increases with increasing CO2 content. The O2 content is in a linear relationship with the contents of CO2 and N2,but in an exponential relationship with the CO content. As the oxygen flow increases,the contents of CO and CO2 increases,the contents of O2 and N2 reduces,and the utilization rate of oxygen improves. The contents of CO and CO2 achieve the maximum when the mass fraction of carbon in the pool is about 1.3%.
