Nitrogen Solubility and the Effect of Carbon in Ladle Slag at 1873K

摘要：

　　The solubility of nitrogen in ladle slag was determined at 1873K under controlled nitrogen and oxygen potentials.Gas slag equilibrium experiments were conducted using molybdenum and graphite crucibles.In the absence of carbon,the nitrogen solubility was very low.The presence of carbon greatly increased the nitrogen solubility in the slag.Low levels of cyanide was detected by wet chemistry,with considerable uncertainty.Cyanide was ruled out as the main reason for the large increase of nitrogen in the presence of pure carbon.The nitrogen solubility was found to increase with increasing SiO2 content both in the absence and presence of carbon.
