Tundish slag line dry material
The invention discloses a tundish slag line dry material, and relates to the technical field of tundish refractory materials, and the tundish slag line dry material comprises the following raw material components by mass: 26-30% of 3-1mm fused magnesite, 10-20% of alumina, 10-20% of alumina, and 10-20% of alumina. The invention relates to a novel composite binding agent system, which comprises the following components in percentage by weight: 22-28% of 1-0mm fused magnesite, 20-27% of 200-mesh fused magnesite, 1.5-2% of trisodium phosphate hexahydrate, 2-2.5% of sodium metasilicate nonahydrate, 1-1.5% of adipic acid, 4-5% of calcium carbonate, 0.3-0.5% of vermiculite and the balance of 5-3mm fused magnesite. And through the synergistic effect of all the components, the medium-temperature and high-temperature strength, corrosion resistance, thermal shock resistance and heat insulation performance of the magnesian dry material are remarkably improved, and comprehensive optimization of the material performance is achieved.
本发明公开了一种中间包渣线干式料，涉及中间包耐火材料技术领域，所述中间包渣线干式料中各原料组份质量百分比为：3‑1mm的电熔镁砂为26～30％，1‑0mm的电熔镁砂为22～28％、200目的电熔镁砂为20～27％、磷酸三钠六水合物为1.5～2％、九水偏硅酸钠为2～2.5％、己二酸为1～1.5％、碳酸钙为4～5％、蛭石为0.3～0.5％、余量为5‑3mm的电熔镁砂，本发明通过采用新型复合结合剂体系，不仅解决了传统酚醛树脂结合剂的环保问题，还通过各成分间的协同效应，显著提高了镁质干式料的中温、高温强度、耐侵蚀性、抗热震性和绝热性能，实现了材料性能的全面优化。
