High-thermal-conductivity and high-density silicon brick for coke oven and preparation method of high-thermal-conductivity and high-density silicon brick
The invention relates to the technical field of refractory materials, in particular to a high-thermal-conductivity and high-compactness silica brick for a coke oven. The silica brick is prepared fromcemented silica, a residual silica brick, a mineralizing agent and lime milk; the mineralizing agent and the lime milk can play a role in enhancing the plasticity of a brick body and promoting the firing conversion of the silica; and the thermal conductivity is enhanced by adding metal oxide. The silicon brick prepared by adopting the formula provided by the invention has excellent physicochemicalindexes. The invention provides a preparation method of the high-thermal-conductivity and high-density silicon brick for the coke oven, so that caves are prevented from being generated in a fired blank brick due to formation of mud pies, and the plasticity of the brick body is enhanced; the volume density of the blank product is improved; the internal structure of the blank product is densified;the overall heat transfer capacity of the blank product is improved; the blank is roasted and dried for multiple times in slurry, so that good grafting is guaranteed, fiber reinforcement is realized,and cracks are prevented from being generated during shrinkage.
本发明涉及耐火材料技术领域，更具体而言，涉及一种焦炉用高导热、高致密硅砖，该硅砖由胶结硅石、残硅砖、矿化剂、石灰乳制得，通过矿化剂、石灰乳可起到增强砖体的可塑性，促进硅石的烧成转化的作用；通过金属氧化物添加增强导热性；采用本发明所述配方制得的硅砖的具有优良理化指标。本发明另一方面提供了一种焦炉用高导热、高致密硅砖的制备方法，避免形成泥团，造成烧成后砖坯产生溶洞，增强砖体的可塑性；提高坯制品体积密度，使其内部结构进一步密制化，提高整体的热传递能力，坯料在浆料中多次焙烧、干燥，保证良好接枝，构成纤维补强，避免在收缩时产生裂纹。
