Al2O3-SiC-C iron runner castable containing composite antioxidant and preparation method of Al2O3-SiC-C iron runner castable
The invention discloses an Al2O3-SiC-C iron runner castable containing a composite antioxidant and a preparation method of the Al2O3-SiC-C iron runner castable. The castable is prepared by mixing corundum, silicon carbide, active Al2O3 micro powder, silica powder, a composite antioxidant, pure calcium aluminate cement, asphalt and an additive. According to the castable, leftovers of polycrystalline silicon and monocrystalline silicon enterprises are recycled to prepare the composite antioxidant, and under the condition that the composite antioxidant interacts with other raw materials, the iron runner castable with the performance completely meeting the use requirements is prepared. The composite antioxidant replaces 98% metal silicon used in the prior art, the sintering strength of the castable is improved, especially the sintering strength at 800-1000 DEG C is remarkably improved, the erosion resistance and the scouring resistance are enhanced, meanwhile, ditch disassembly is facilitated, the integrity of the residual ditch material is guaranteed, the production cost and the input cost are greatly reduced, and the production cost and the investment cost are greatly reduced. And the consumption of resources and energy is obviously reduced.
本发明公开了一种含复合型抗氧化剂的Al2O3‑SiC‑C铁沟浇注料及其制备方法。该浇注料由刚玉、碳化硅、活性Al2O3微粉、硅微粉、复合型抗氧化剂、纯铝酸钙水泥、沥青，以及外加剂混合制备而成。该浇注料以回收多晶硅和单晶硅企业的下脚料制得复合型抗氧化剂，在与其他原料相互作用的条件下，制备得到了性能完全符合使用要求的铁沟浇注料。本发明的复合型抗氧化剂替代了现有技术所用的98%含量的金属硅，提高了浇注料的烧结强度，尤其是800～1000℃的烧结强度显著提高，增强了抗侵蚀和抗冲刷性能，同时便于拆沟，保证了残沟料的完整性，大大降低了生产成本及投入成本，明显减少了对资源和能源的消耗。
