Anti-scouring tundish dry material
The invention discloses an anti-scouring tundish dry material, and relates to the technical field of tundish refractory materials, and the tundish dry material comprises the following raw material components by mass: 28-32% of 3-1mm fused magnesite, 10-20% of alumina powder, 10-20% of alumina powder, and the balance of alumina powder. The invention relates to an ultra-low thermal conductivity refractory brick which comprises the following components in percentage by weight: 22-30% of 1-0mm fused magnesia, 20-28% of 200-mesh fused magnesia, 3-4.5% of phenolic resin, 1-1.4% of rectorite powder, 0.2-0.3% of SiO2 aerogel powder and the balance of 5-3mm fused magnesia. According to the ultra-low thermal conductivity refractory brick, the special layered structure of the rectorite powder and the ultra-low thermal conductivity of the SiO2 aerogel powder are ingeniously utilized; through the synergistic effect of the two components, the tundish dry material successfully solves the problems of insufficient strength and poor thermal insulation performance on the basis of keeping the original good fire resistance, and the efficiency and economical efficiency of a continuous casting process are remarkably improved.
本发明公开了一种抗冲刷中间包干式料，涉及中间包耐火材料技术领域，所述中间包干式料中各原料组份质量百分比为：3‑1mm的电熔镁砂为28～32％，1‑0mm的电熔镁砂为22～30％、200目的电熔镁砂为20～28％、酚醛树脂为3～4.5％、累托石粉为1～1.4％、SiO2气凝胶粉为0.2～0.3％、余量为5‑3mm的电熔镁砂，本发明巧妙利用了累托石粉的特殊层状结构和SiO2气凝胶粉的超低导热特性，两者的协同作用使得本发明的中间包干式料在保持原有良好耐火性能的基础上，成功解决了强度不足与保温性能不佳的问题，显著提高了连铸工艺的效率与经济性。
