Anti-erosion Al2O3-SiC-C iron runner castable containing carbon black and graphite electrode powder and preparation method of anti-erosion Al2O3-SiC-C iron runner castable
The invention discloses an anti-erosion Al2O3-SiC-C iron runner castable containing carbon black and graphite electrode powder and a preparation method of the anti-erosion Al2O3-SiC-C iron runner castable. The castable mainly consists of 58 to 62 percent of corundum, 18 to 25 percent of silicon carbide, 3 to 7 percent of active Al2O3 micro powder, 1.5 to 4 percent of silicon micro powder, 1.5 to 2.5 percent of antioxidant metal silicon, 3 to 5 percent of pure calcium aluminate cement, 1.5 to 2.5 percent of asphalt, 0.5 to 1.5 percent of carbon black and 0.5 to 1.5 percent of graphite electrode powder. In addition, explosion-proof fibers accounting for 0.03-0.15% of the total weight of the raw materials and a water reducing agent accounting for 0.05-0.15% of the total weight of the raw materials are added. The anti-erosion Al2O3-SiC-C castable for the iron runner is prepared by uniformly mixing the raw materials according to the dosage in proportion. The performance of the castable completely meets the use requirements, the erosion resistance and the scouring resistance are enhanced, meanwhile, ditch dismantling is convenient, and remarkable social and economic benefits and a very good application prospect are achieved.
本发明公开了一种含炭黑和石墨电极粉的抗侵蚀Al2O3‑SiC‑C铁沟浇注料及其制备方法。该浇注料主要由刚玉58～62％、碳化硅18～25％、活性Al2O3微粉3～7％、硅微粉1.5～4％、抗氧化剂金属硅1.5～2.5％、纯铝酸钙水泥3～5％、沥青1.5～2.5％、炭黑0.5～1.5％和石墨电极粉0.5～1.5％组成；另外，加入占各种原料总重量0.03～0.15％的防爆纤维和0.05～0.15％的减水剂。将各种原料按照配比比例的用量混合均匀，得到产品抗侵蚀Al2O3‑SiC‑C铁沟浇注料。本发明浇注料的性能完全符合使用要求，并且增强了抗侵蚀和抗冲刷性能，同时便于拆沟，具有显著的社会经济效益及很好的应用前景。
