以风淬钢渣和高炉渣为主要原料,采用一次烧结法制备微晶玻璃。结果表明,该方法制备的微晶玻璃主晶相为钙铝黄长石(Ca2Al2SiO7),还有少量的镁黄长石(Ca2MgSi2O7),钢渣最大用量达到50%;随着风淬钢渣含量的增加,样品的最佳烧结温度逐渐增加;烧结温度对样品析晶性能的影响明显大于风淬钢渣含量的影响;样品的抗折强度随风淬钢渣的增加呈现出先增大后减小的趋势;样品的密度随风淬钢渣的增加而逐渐减小;直接用风淬钢渣和高炉渣制备出的微晶玻璃具有良好的抗折强度和耐酸碱性,抗折强度最大可达90 MPa,该方法为综合治理冶金渣污染及其综合利用开辟了新的途径。
The wind-quenched steel slag and blast furnace slag as the main raw material, the use of a sintering method for the preparation of glass-ceramics. The results show that the main crystalline phase of the glass-ceramics prepared by this method is Ca-Al 2o feldspar (Ca2Al2SiO7), with a small amount of Ca2MgSi2O7 and the maximum amount of slag is up to 50%. With the increase of the content of the steel, The sintering temperature increases gradually; the influence of sintering temperature on the crystallinity of the sample is obviously greater than that of the steel with the properties of air quench; the flexural strength of the sample increases first and then decreases with the increase of the steel slag; Quenched steel slag increases gradually reduced; direct use of steel quenched steel slag and blast furnace slag prepared by the glass has good flexural strength and acid resistance, flexural strength up to 90 MPa, the method for the comprehensive management of metallurgy Slag pollution and its comprehensive utilization have opened up new avenues.
