Alumina fiber reinforced castable and method for preparing prefabricated part by using same
The invention belongs to the field of refractory materials. The invention provides an alumina fiber reinforced castable. The castable is composed of the following components in parts by weight: 48 to82 parts of black aluminum sand, 11 to 22 parts of white corundum powder, 8 to 17 parts of alpha-alumina powder, 0.1 to 1 part of alumina fibers, 5 to 7 parts of cement, 0.8 to 1.5 parts of steel fibers and 1.0 to 1.8 parts of an additive. The invention further provides a preparation method of the prefabricated part. The invention also provides an application of the castable as a permanent liningmaterial of a ladle wall of a steel ladle. The alumina fibers are used as a microcosmic skeleton structure of a matrix, and the steel fibers are used as a whole macrocosmic matrix skeleton. The castable has high normal-temperature strength and high-temperature strength and excellent high-temperature breaking strength and thermal shock resistance, and the service life of the permanent lining of theladle wall of the steel ladle is obviously prolonged.
本发明属于耐火材料领域。本发明提供了一种氧化铝纤维增强的浇注料，所述浇注料包括如下重量份的组分：黑铝砂48～82份，白刚玉粉11～22份，α‑氧化铝粉8～17份，氧化铝纤维0.1～1份，水泥5～7份，钢纤维0.8～1.5份和外加剂1.0～1.8份。本发明进一步提供了预制件的制备方法。本发明还提供了所述的浇注料作为钢包包壁永久衬材料的应用。本发明用氧化铝纤维作为基质的微观骨架结构，钢纤维作为整个宏观基质骨架。该浇注料具有较高的常温强度、高温强度，具有优异的高温抗折强度和抗热震性，明显提高了钢包包壁永久衬的使用寿命。
