Low-carbon submersed nozzle lining and preparation method thereof
The invention relates to the technical field of refractory materials, in particular to a low-carbon submersed nozzle lining and a preparation method thereof. The low-carbon submersed nozzle lining is prepared from, by mass, 30-50 parts of zirconium mullite, 15-35 parts of a ZrO2-based porous heat insulation material, 25-40 parts of white corundum, 0.5-2 parts of an antioxidant, 0.5-2 parts of a sintering aid, 0.5-2 parts of an additive, 1-3 parts of composite graphitized carbon black and 2-10 parts of a binding agent. The invention also comprises a preparation method of the low-carbon submersed nozzle lining. The preparation method comprises the following steps: mixing and co-grinding; preparation of a granulation material, a first forming material and a second forming material; drying; and firing and drying to obtain the low-carbon submersed nozzle lining. The problems that an existing submersed nozzle lining is insufficient in thermal shock stability and strength and the like in the prior art are solved by improving and increasing raw material components and the proportions of the raw material components.
本发明涉及耐火材料技术领域，尤其是一种低碳浸入式水口内衬及其制备方法，按质量份数计算，包括：锆莫来石30份～50份，ZrO2基多孔隔热材料15份～35份，白刚玉25份～40份，抗氧化剂0.5份～2份，助烧结剂0.5份～2份，添加剂0.5份～2份，复合石墨化炭黑1份～3份，结合剂2份～10份，本发明还包括一种低碳浸入式水口内衬的制备方法，包括混合共磨，制备造粒料、第一成型料、第二成型料，干燥、烧制烘干后获得低碳浸入式水口内衬，通过改善和增加原材料成分及其比例以解决现有技术中存在的现有的浸入式水口内衬热震稳定性能和强度不足等问题。
