Optimization Chemical Composition of the Blast Furnace Slag with Uniform Design
Using the industrial limestone,fly ash and pure chemical reagents as raw materials,the blast furnace slag was prepared in the simulation condition of the actual slag-making process.Using uniform design method,the influence of blast furnace slag composition factors such as quaternary alkalinity,ratio of CaO/MgO and ratio of SiO2/Al2O3 on the glass content of blast furnace slag were studied in the present in investigation,the relationship between glass content and the various factors has been obtained through regression analysis,and the main influence factors and the optimum blast furnace slag compositions been found out.The results showed that,the impact of various factors on the glass content of granulated blast furnace slag was quaternary alkalinity > ratio of SiO2/Al2O3 > ratio of CaO/MgO.According to the significance test of the regression equation and the verification experiment,it was concluded that the optimum compositions of granulated blast furnace slag were: the quaternary alkalinity was 0.85,the ratios of CaO/MgO and SiO2/Al2O3 were 11.5 and 6.5 respectively,and in this condition,the glass content of granulated blast furnace slag reached to 98.47%.
