Minitab在炉渣黏度实验数据分析中的应用

Application in the Experimental Data Analysis of the Slag Viscosity with Minitab Software

利用Minintab软件对高炉渣黏度实验数据进行了单因子方差计算,得到了碱度和化学成分变化对炉渣黏度的影响规律。结果表明:在计算条件下,当炉渣碱度大于1.02,w(MgO)小于11.95%或w(TiO2)小于12.57%时,碱度、MgO和TiO2的含量的变化对炉渣黏度均没有显著影响;而当炉渣碱度小于1.02,w(MgO)大于13.95%或w(TiO2)大于13.57%时,三因素的变化对炉渣黏度有显著影响;炉渣w(Al2O3)控制在12.75%为宜。

The single factor variance of viscosity experimental data of blast furnace slag was calculated by Minitab software. The influence rule of slag basicity and chemical compositions on the slag viscosity was obtained. The results show that there have insignificant effects on the slag viscosity when the slag basicity is over than 1.02, MgO mass fraction is less than 11.95% or TiO2 mass fraction is less than 12.57%. While the slag basicity can be influenced significantly with the slag basicity less than 1.02, MgO mass fraction over than 13.95% and TiO2 mass fraction over 13.57%. The A1203 mass fraction of the slag is contored below 12.75%
