Al2O3-SiC-C iron runner castable taking FDN and sodium pyrophosphate as water reducing agents and preparation method of Al2O3-SiC-C iron runner castable
The invention discloses an Al2O3-SiC-C iron runner castable with FDN and sodium pyrophosphate as water reducing agents and a preparation method of the Al2O3-SiC-C iron runner castable. The castable is prepared from the following raw materials: 60 to 65 percent of brown aluminum oxide, 18 to 25 percent of silicon carbide, 3 to 8 percent of active Al2O3 micro powder, 1.5 to 4 percent of silicon micro powder, 1.5 to 2.5 percent of antioxidant, 3 to 5 percent of pure calcium aluminate cement and 1.5 to 2.5 percent of asphalt. In addition, a water reducing agent FDN accounting for 0.2-0.4% of the total weight of the raw materials and sodium pyrophosphate accounting for 0.1-0.2% of the total weight of the raw materials are added as a composite water reducing agent, and explosion-proof fibers accounting for 0.03-0.15% of the total weight of the raw materials are added. The preparation method comprises the following steps: uniformly mixing the prepared raw materials to obtain the product Al2O3-SiC-C iron runner castable. The water reducing effect of the product is obvious, the water adding amount is obviously reduced, and the production rhythm of on-site rapid pouring and rapid baking can be completely met.
本发明公开了一种以FDN和焦磷酸钠为减水剂的Al2O3‑SiC‑C铁沟浇注料及其制备方法。本发明浇注料的原料组成为：棕刚玉60～65％、碳化硅18～25％、活性Al2O3微粉3～8％、硅微粉1.5～4％、抗氧化剂1.5～2.5％、纯铝酸钙水泥3～5％和沥青1.5～2.5％；另外，加入占上述各种原料总重量0.2～0.4％的减水剂FDN和0.1～0.2％的焦磷酸钠作为复合减水剂，并加入占上述各原料总重量0.03～0.15％的防爆纤维。将配制的各种原料混合均匀，得到产品Al2O3‑SiC‑C铁沟浇注料。本发明产品减水效果明显、加水量明显减少，完全能够满足现场快速浇注、快速烘烤的生产节奏。
