Fiber-reinforced refractory castable and preparation method thereof
The invention relates to the technical field of refractory castable, in particular to fiber-reinforced refractory castable and a preparation method thereof. Raw materials of the fiber-reinforced refractory castable comprise a refractory castable and fibers, the fibers are at least one of metal aluminum fibers and magnesium-aluminum alloy fibers, and the mass of the fibers accounts for 0.5%-4% of the mass of the refractory castable. By adding a certain amount of metal aluminum fiber and/or magnesium aluminum alloy fiber into the refractory castable, substances such as aluminum oxide, magnesium oxide, magnesium aluminate spinel and the like are formed in situ, so that the refractory performance of the material is improved, the porosity of the material is reduced, the high-temperature breaking strength and the like of the material are greatly improved, and multiple purposes are achieved; the refractory castable is obviously superior to the existing refractory castable added with steel fibers.
本发明涉及耐火浇注料技术领域，尤其涉及一种纤维增强耐火浇注料及其制备方法。所述纤维增强耐火浇注料其原料包括耐火浇注料和纤维，所述纤维为金属铝纤维和镁铝合金纤维中的至少一种，所述纤维的质量占所述耐火浇注料的质量的0.5%~4%。本发明通过在耐火浇注料中添加一定量的金属铝纤维和/或镁铝合金纤维，使其原位形成氧化铝、氧化镁、镁铝尖晶石等物质，从而实现提高材料耐火性能，降低材料气孔率，大幅提高材料的高温抗折强度等性能，一举多得，明显优于现有添加钢纤维的耐火浇注料。
