Low-cost aluminum oxide-silicon carbide-carbon castable and preparation method thereof
The invention discloses an alumina-silicon carbide-carbonaceous castable and a preparation method thereof. The alumina-silicon carbide-carbonaceous castable can be applied to blast furnace tapping channels and iron ladle linings. The raw materials comprise fused compact corundum, silicon carbide, carbon, calcium aluminate cement, activated aluminum oxide micro-powder, silicon oxide micro-powder and a water reducing agent. In addition, the ceramic waste is introduced to partially replace silicon carbide particles or fine powder, so that the cost of the material is reduced. The method has obvious advantages in cost control, and the indexes of the key performance of the material are not reduced, so that the use requirements can be met. Therefore, the method has a certain economic value and can be popularized to industrial production.
本发明公开了一种氧化铝‑碳化硅‑碳质浇注料及其制备方法，可应用在高炉出铁沟、铁包内衬。其原料包括电熔致密刚玉、碳化硅、碳素、铝酸钙水泥、活性氧化铝微粉、氧化硅微粉、减水剂。此外，通过引入陶瓷废料来部分取代碳化硅颗粒或细粉，以此降低材料的成本。本发明在成本控制上有明显的优势，并且材料关键性能的指标没有下降，能够满足使用要求。因此，本发明有一定的经济价值，可推广到工业生产中。
