摘要：新疆公司铁水中钒含量较高，转炉吹炼过程钒氧化进入渣中，在放钢和吹氩过程中，进入钢包含钒炉渣和硅铁、碳粉等还原剂，利用钢液对混合物的冲击搅拌作用发生金属热还原反应，使合金工难以准确的估算回钒量。通过采集大量数据，根据挡渣情况、渣况进行统计表明，挡渣效果及炉渣粘稀最高能使钢中钒上升0．017％。综合考虑回钒量，合理加入钒氮合金，满足了钢种成分要求。保证了钢材性能，提高产品质量。
The content of Vanadium in molten iron of Xinjiang Company was higher. Vanadium was oxi- dized and went into slag during converter blowing process, then entered V-containing slag and reducing a- gents of ferrosilicon and carbon powder in the process of molten-steel emitting and argon-blowing proces- ses, thus the metal thermal reduction reaction was happened by using the impacting and stirring effects of molten steel to mixture, leading to the more difficulty to estimate the Vanadium-increasing quanti- ty. Through collecting mass of data and carrying out the statistics of slag-stopping and slag states, the re- sults show that, the slag-stopping effect and slag viscosity can make Vanadium in steel go up by 0. 017% at the maximum degree. After that, the overall consideration of Vanadium-increasing and the reasonable adding of Vanadium-nitrogen alloy have satisfied the chemical composition requirements of steels, ensured the steel properties, and increased the oroduct qualitv.
