Refractory material for tundish thermal insulation layer, tundish thermal insulation layer and preparation method of tundish thermal insulation layer
The invention belongs to the technical field of refractory materials for steelmaking and continuous casting, and discloses a refractory material for a tundish insulating layer, the tundish insulating layer and a preparation method of the tundish insulating layer. The refractory material for the tundish insulating layer is prepared from the following raw materials in percentage by mass: 50 to 65 percent of heavy aggregate, 20 to 30 percent of light filler, 5 to 10 percent of binding agent, 3 to 8 percent of additive, 3 to 8 percent of volume stabilizer and 0.5 to 3 percent of metal fiber. The refractory material is mixed with water to obtain a mixture, the mixture is poured into a gap between a tundish and a blank film or directly sprayed or smeared on the inner wall of the tundish, and the tundish heat preservation layer can be obtained after forming and drying. The novel refractory material is developed and is used for preparing the tundish insulating layer, so that the insulating layer has the characteristics of good insulating property, high strength, thermal shock resistance, slag corrosion resistance, long service life and the like.
本发明属于炼钢连铸用耐火材料技术领域，公开了一种中间包保温层用耐火材料、中间包保温层及其制备方法。所述中间包保温层用耐火材料由以下质量百分比的原料组成：重质骨料50‑65％、轻质填充料20‑30％、结合剂5‑10％、添加剂3‑8％、体积稳定剂3‑8％、金属纤维0.5‑3％。将该耐火材料与水混合得到混合料，将混合料倒入中间包与胎膜的缝隙中，或直接喷涂、涂抹于中间包内壁上，成型后干燥，即可得到中间包保温层。本发明通过开发新型耐火材料，以新型耐火材料制备中间包保温层，使保温层同时具有保温性能好、强度高、抗热震、抗渣侵蚀以及寿命长等特点。
