Refractory castable
The invention relates to a refractory castable. The refractory castable is prepared from the following raw materials: first aggregate, lightweight aggregate with a porous structure, powder, a binding agent, a water reducing agent and refractory fibers, wherein the content of the first aggregate is 35%-55% by mass, the content of the lightweight aggregate is 5%-15% by mass, the content of the powder material is 30%-40% by mass, the content of the binding agent is 5%-10% by mass, the content of the water reducing agent is 0.5%-1.5% by mass, and the content of the refractory fiber is 1%-2% by mass. The refractory castable provided by the invention is a light-weight heat-preservation refractory castable with small density, low thermal conductivity, good heat preservation performance and good high-temperature use performance, heat storage loss and heat dissipation loss of a furnace body are reduced while the use conditions of an industrial furnace and high-temperature equipment are met, and the purposes of saving energy, reducing consumption and prolonging the service life of the furnace are achieved.
本申请涉及一种耐火浇注料，所述耐火浇注料的原料包括：第一骨料、具有多孔结构的轻质骨料、粉料、结合剂、减水剂以及耐火纤维；其中，以质量分数计，所述第一骨料的含量为35％～55％，所述轻质骨料的含量为5％～15％，所述粉料的含量为30％～40％，所述结合剂的含量为5％～10％，所述减水剂的含量为0.5％～1.5％，所述耐火纤维的含量为1％～2％。本申请提供的耐火浇注料为密度小，导热率低，保温性能好，并具有良好的高温使用性能的轻量化保温耐火浇注料，在满足工业窑炉和高温设备使用条件的同时，减少炉体蓄热损失及散热损失，达到节能降耗并且提高窑炉使用寿命的目的。
