High-strength wear-resistant castable
The invention relates to the technical field of castables, in particular to a high-strength wear-resistant castable, which overcomes the defect that the castable strength of an existing castable is reduced in metallurgy, power generation, fluidized bed, building material and waste incineration environments. The high-strength wear-resistant castable comprises the following raw material components and externally addition components in parts by mass: 50-60 parts of chrome corundum, 7-10 parts of silicon carbide, 5-8 parts of calcium hexaluminate, 1-3 parts of Yongji clay, 3-5 parts of active magnesium oxide, 8-12 parts of silicon nitride powder, 3-6 parts of zircon sand, 3-6 parts of zirconium zinc silicate powder, 3-6 parts of andalusite micro-powder, 1 part of franklinite micro-powder, 3-6 parts of zinc oxide micro-powder and 3-6 parts of flint clay. A composite superfine powder and an expanding agent are added, so that the raw materials are subjected to chemical reaction and expand in the slow heating process, and certain assistance is provided for strength reduction caused by shrinkage of the castable.
本发明涉及浇注料技术领域，尤其涉及一种高强耐磨浇注料，解决了现有浇注料在冶金、发电、流化床、建材、垃圾焚烧环境中浇注料强度下降的缺点，包括原料组分和外加组分：所述原料组分按质量份数计分别为：铬刚玉50‑60份，碳化硅7‑10份，六铝酸钙5‑8份，永吉黏土1‑3份，活性氧化镁3‑5份，氮化硅粉8‑12份，锆英砂3‑6份，硅酸锌锆粉3‑6份，红柱石微粉3‑6份，铁锌尖晶石微粉1份，氧化锌微粉3‑6份，焦宝石3‑6份，本发明中加入复合超微粉和膨胀剂使原料发生化学反应在缓慢升温过程中发生膨胀的现象，这对浇注料收缩造成的强度下降有一定的助力。
