Molten copper erosion resistant castable
The invention discloses a molten copper erosion resistant castable, and relates to the technical field of castable, the molten copper erosion resistant castable comprises the following components by weight: 30-35 parts of aggregate particles; 10 parts of corundum fine powder; 3 to 6 parts of aerogel powder; 1-2 parts of a micro powder mixture; 3-5 parts of a binding material; wherein the aggregate particles are obtained by mixing mullite particles and improved spinel particles according to the weight ratio of 3: 1; the binding material is prepared by mixing aluminate cement, sodium silicate, soft clay and graphite powder according to the weight ratio of (4-5): 2: 1: 1. The aerogel is prepared from the following components in parts by weight: 3 to 5 parts of titanium acetate, 9 to 15 parts of cupric acetate and 25 to 35 parts of tetraethoxysilane. The strength and the high temperature resistance of the castable are improved through improved spinel particles in the aggregate particles; through the aerogel particles, the heat conductivity coefficient of the castable is reduced, and the friction force and the bonding force with other components of the castable are increased.
本发明公开了一种抗铜液侵蚀浇注料，涉及浇注料技术领域，按重量分数计，包括：骨料颗粒料30‑35份；刚玉细粉10份；气凝胶粉末3‑6份；微粉混合物1‑2份；结合料3‑5份；其中，骨料颗粒料由莫来石颗粒、改进尖晶石颗粒，按重量比3:1混合得到；所述结合料由铝酸盐水泥、硅酸钠、软质粘土、石墨粉末组成，按重量比为4～5：2：1：1混合配制得到。所述气凝胶按照重量份数计，包括乙酸钛3‑5份，乙酸铜9‑15份，正硅酸乙酯25‑35份。通过骨料颗粒物中的改进尖晶石颗粒增加浇注料的强度和耐高温性能；通过气凝胶颗粒，降低浇注料的导热系数、增大与浇注料其他组分的摩擦力和粘结力。
