Nano-carbon-containing refractory castable for desulfurization stirrer and preparation method of nano-carbon-containing refractory castable
The invention discloses a nano-carbon-containing refractory castable for a desulfurization stirrer. The castable comprises raw materials with the particle size being 1 mm or above, raw materials withthe particle size being larger than or equal to 0.1 mm and smaller than 0.1 mm and raw materials with the particle size being smaller than 0.1 mm. The raw materials with the particle size being smaller than 0.1 mm are prepared from pure fused mullite with the particle size being 325 mesh and dense corundum fine powder with the particle size being 325 mesh. The 325-mesh pure fused mullite and the 325-mesh dense corundum fine powder are carbon film nano-coated pure fused mullite and carbon film nano-coated dense corundum fine powder respectively. The invention also discloses a preparation methodof the castable. According to the castable disclosed by the invention, the thermal shock stability and the slag and molten iron erosion penetration resistance of the castable are improved, so that the castable is good in comprehensive performance and low in raw material cost, and a prepared stirrer is long in service life and low in consumption cost.
本发明公开了一种含纳米碳的脱硫搅拌器用耐火浇注料。该浇注料包括粒度为1mm以上的原料，0.1mm≤粒度<1mm的原料以及粒度小于0.1mm的原料，所述粒度小于0.1mm的原料包括325目的纯电熔莫来石和325目的致密刚玉细粉。所述325目的纯电熔莫来石和325目的致密刚玉细粉为碳膜纳米包覆纯电熔莫来石和碳膜纳米包覆致密刚玉细粉。本发明还公开了上述浇注料的制备方法。本发明的浇注料由于提高了浇注料的热震稳定性、抗熔渣与铁水的侵蚀渗透能力，因此浇注料综合性能好、原材料成本低，所制备的搅拌器使用寿命长、消耗成本低。
