高压-底吹氮法高氮钢精炼的热力学

Experimental Study on Thermodynamics of High Nitrogen Steel Refining with High Pressure and Bottom-blown Nitrogen

保持恒定的底吹N_2流量,在高温高压反应釜内对高氮钢的精炼进行了热力学实验,对实验结果进行了正交分析.研究结果表明,在影响高氮钢氮溶解度的因素中压力影响最大,氮溶解度随着压力的升高而增大;合金组分(Cr,Mn)的影响次之且Cr的影响大于Mn,氮溶解度随着Cr,Mn含量增加而增大;温度的影响最小,氮溶解度随着温度的升高而减小.

Keeping constant velocity of bottom-blown nitrogen,the experimental study on thermodynamics of high nitrogen steel refining was carried out in a high temperature and high pressure reaction furnace.The experimental result was analyzed with orthogonal method.The result indicated that among the influential factors which affect the nitrogen solubility,pressure was uppermost one,and the nitrogen solubility increased as the pressure rised.The content of alloy(Cr,Mn)took the second place,and the influence of Cr wa...
