To explore the service performance difference of tabular alumina from different sources, the longevity application of refractory products can be realized through the targeted selection of raw materials. In this paper, three types of tabular alumina aggregates with different microstructures were selected for corrosion tests of ladle slag with different basicities. The influence of microstructure on the interface reaction of tabular alumina aggregate to resist slag erosion was investigated, and the dominant pore structure and action mechanism of tabular alumina aggregate under a high basicity and a low basicity environment were analyzed. The results show that the number of cluster porosities is directly proportional to the amount of alumina dissolved in the erosion process. Under high basicity conditions (i.e., the mass ratio of CaO to SiO2 is greater than 4), the composite lamellar structure of CA2+CA6 can be formed at the slag-material interface, which plays a certain protective role. The thickness of composite layer is inversely proportional to the number of cluster porosities. Under the condition of a low basicity (i.e., the mass ratio of CaO to SiO2 is approximately 1), the cluster pore structure leads to the formation of massive fine CA6 grains, and the erosion resistance is poor. However, a small amount of pore cluster structure leads to the formation of CA6 deposition layer on the aggregate surface and the formation of larger-sized CA6 crystal bridging regions, which can resist the slag erosion.

为了探究不同来源板状刚玉的使用性能差异,从而通过对原料的针对性选择实现耐火制品的长寿化应用。以不同碱度的钢包渣为侵蚀介质对3种不同显微结构特征的板状刚玉骨料进行侵蚀实验,揭示了不同显微结构对板状刚玉骨料抵抗熔渣侵蚀过程中界面反应的影响,明确了高碱度与低碱度环境下的优势孔隙结构与作用机制。研究表明:由于气孔簇结构的数量与侵蚀过程中的氧化铝溶解量成正比,在高碱度条件下(CaO和SiO2质量比大于4),渣料界面会生成二铝酸钙(CA2)及六铝酸钙(CA6)的复合层状结构,起到一定的保护作用,复合层的厚度与气孔簇的数量成反比;在低碱度条件下(CaO和SiO2质量比约等于1),圆形孔隙结构特点导致熔渣内生成大量CA6细晶结构,抗侵蚀效果较差,而少量的气孔簇结构导致在骨料表面形成CA6沉积层并生成更大尺寸CA6晶体桥接区域,从而抵抗熔渣侵蚀。

为了探究不同来源板状刚玉的使用性能差异,从而通过对原料的针对性选择实现耐火制品的长寿化应用。以不同碱度的钢包渣为侵蚀介质对3种不同显微结构特征的板状刚玉骨料进行侵蚀实验,揭示了不同显微结构对板状刚玉骨料抵抗熔渣侵蚀过程中界面反应的影响,明确了高碱度与低碱度环境下的优势孔隙结构与作用机制。研究表明:由于气孔簇结构的数量与侵蚀过程中的氧化铝溶解量成正比,在高碱度条件下(CaO和SiO2质量比大于4),渣料界面会生成二铝酸钙(CA2)及六铝酸钙(CA6)的复合层状结构,起到一定的保护作用,复合层的厚度与气孔簇的数量成反比;在低碱度条件下(CaO和SiO2质量比约等于1),圆形孔隙结构特点导致熔渣内生成大量CA6细晶结构,抗侵蚀效果较差,而少量的气孔簇结构导致在骨料表面形成CA6沉积层并生成更大尺寸CA6晶体桥接区域,从而抵抗熔渣侵蚀。

To explore the service performance difference of tabular alumina from different sources, the longevity application of refractory products can be realized through the targeted selection of raw materials. In this paper, three types of tabular alumina aggregates with different microstructures were selected for corrosion tests of ladle slag with different basicities. The influence of microstructure on the interface reaction of tabular alumina aggregate to resist slag erosion was investigated, and the dominant pore structure and action mechanism of tabular alumina aggregate under a high basicity and a low basicity environment were analyzed. The results show that the number of cluster porosities is directly proportional to the amount of alumina dissolved in the erosion process. Under high basicity conditions (i.e., the mass ratio of CaO to SiO2 is greater than 4), the composite lamellar structure of CA2+CA6 can be formed at the slag-material interface, which plays a certain protective role. The thickness of composite layer is inversely proportional to the number of cluster porosities. Under the condition of a low basicity (i.e., the mass ratio of CaO to SiO2 is approximately 1), the cluster pore structure leads to the formation of massive fine CA6 grains, and the erosion resistance is poor. However, a small amount of pore cluster structure leads to the formation of CA6 deposition layer on the aggregate surface and the formation of larger-sized CA6 crystal bridging regions, which can resist the slag erosion.
