摘要:
为了改善镁白云石材料的性能,以白云石、高硅菱镁矿、硅石、氧化铁粉为主要原料,采用二步煅烧和消化工艺合成氧 化铁含量分别 0、0. 5%、1. 0%、1. 5%(质量分数下同)的 4 个系列的稳定镁白云石砂,再以此为主要原料制备相应 4 个系列的 镁白云石制品。 探究了氧化铁含量对试样物理性能、抗水化性、挂窑皮性能的影响,并分析了试样物相组成和显微结构。 结 果表明:随着氧化铁含量的增加,试样的常温抗折强度和常温耐压强度增大,高温抗折强度和试样粘结强度降低,试样的热震 残余强度保持率先升高后降低。 当氧化铁含量增加至 1. 5%时,试样的水化增重率降低至 0. 12%,抗水化性提高。 由 XRD 图 谱分析得出,试样的主晶相为方镁石、硅酸二钙和硅酸三钙,并且随着氧化铁含量的增加,C2 S 和 C3 S 的衍射峰变强,峰形尖 锐,说明氧化铁可以促进 C2 S 和 C3 S 的晶体发育,提高试样的致密度。
Abstract:
In order to improve the performance of magnesia dolomite materials, stabilized magnesium dolomite refractory materials whose iron oxide content ( mass fraction) was 0, 0. 5%, 1. 0%, 1. 5%, respectively, were prepared from natural dolomite, high silicon magnesite, silica and iron oxide powder by two-stage calcination and slaking process. The influence of iron oxide content on the physical properties, hydration resistance and coatability adherence of the samples was investigated. The phase composition and microstructure of the specimens were characterized. The results show that, as the iron oxide content increases, the room temperature flexural strength and the room temperature compressive strength increase, the high temperature flexural strength and the adherence strength decrease, and the retention rate of the thermal shock strength of the sample first increases and then decreases. With the iron oxide content increasing to 1. 5%, the hydration weight gain rate of the sample decreases to 0. 12%, and the hydration resistance improves. According to the XRD spectrum analysis, the main crystal phases of the sample are periclase, dicalcium silicate and tricalcium silicate. With the increase of iron oxide content, the diffraction peaks of C2 S and C3 S become stronger and the peak shapes are sharp. It shows that iron oxide can promote the growth of C2 S and C3 S crystals and increase the density of the sample.
