Wear-resistant refractory castable and production process thereof
The invention provides a wear-resistant refractory castable, which comprises the following components in parts by mass: 22-26 parts of a coarse material with a particle size of 3-5 mm, 19-33 parts of a medium material with a particle size of 0.05-1 mm and 45-55 parts of a fine material with a particle size of less than 0.01 [mu]m, wherein the coarse material is prepared from the following components in parts by weight: 69 to 71 parts of SiO2, 15 to 20 parts of Al2O3, 0.5 to 1.0 part of Fe2O3, 0.7 to 1.0 part of CaO, 2 to 3 parts of K2O, 4 to 5 parts of Na2O and 0.3 to 0.5 part of MgO, the medium material is prepared from 71 to 72 parts of SiO2, 14 to 15 parts of Al2O3, 1.5 to 2 parts of Fe2O3, 1.9 to 2.5 parts of FeO, 0.05 to 0.10 part of MnO, 0.5 to 0.7 part of MgO, 2.5 to 3 parts of Na2O and 5 to 6 parts of K2O, and the fine material is prepared from 1 to 2 parts of CaF2, 0.5 to 1.0 part of NaCO3, 22 to 25 parts of SiO2, 54 to 61 parts of Al2O3, 7 to 10 parts of SiC and 8 to 11 parts of Na2SiO3.9H2O. Compared with the conventional castable, the wear-resistant refractory castable increases the use amount of fine materials and reduces the use amount of coarse materials, so that the castable is smoother after being poured, the impact force in the use process is reduced, and the wear resistance and the adhesive force are improved;.
本发明提供了一种耐磨耐火浇注料，其包括以下质量份的成分：粒径为3‑5mm的粗料22‑26份、粒径为0.05‑1 mm中料19‑33份和粒径＜0.01 μm的细料45‑55份；其中，所述粗料包括SiO2 69‑71份、Al2O3 15‑20份、Fe2O3 0.5‑1.0份、CaO 0.7‑1.0份、K2O 2‑3份、Na2O 4‑5份和MgO 0.3‑0.5份；所述中料包括SiO2 71‑72份；Al2O3 14‑15份、Fe2O3 1.5‑2份、FeO 1.9‑2.5份、MnO 0.05‑0.10份、MgO 0.5‑0.7份、Na2O 2.5‑3份、K2O 5‑6份；所述细料包括CaF2 1‑2份、NaCO3 0.5‑1.0份、SiO2 22‑25份、Al2O3 54‑61份、SiC 7‑10份、Na2SiO3•9H2O 8‑11份。该耐磨耐火浇注料相比与常规的浇注料一方面增加细料用量，减少粗料用量，使得浇注之后更加平整，降低使用过程中受到的冲击力，提高耐磨性和附着力。
