Andalusite silicon carbide brick for submerged arc furnace and preparation method of andalusite silicon carbide brick
The invention provides an andalusite silicon carbide brick for a submerged arc furnace and a preparation method of the andalusite silicon carbide brick, and belongs to the technical field of refractory materials. The main material comprises the following components in percentage by mass: 70-75% of andalusite with the particle size of less than 5mm, 8-12% of silicon carbide with the particle size of less than 1mm, 5-10% of white corundum and/or tabular corundum with the particle size of less than 0.074 mm, 3-5% of modified alpha-Al2O3 micro powder and 5-8% of Guangxi white mud fine powder with the particle size of less than 0.074 mm; the auxiliary material comprises the following components: binding agent dextrin, zirconium-doped titanium oxide and water, the mass of the binding agent dextrin accounts for 0.5-0.8% of the mass of the main material, the mass of the zirconium-doped titanium oxide accounts for 1-2% of the mass of the main material, and the mass of the water accounts for 3-3.5% of the mass of the main material. The method ensures that the prepared product is excellent in mechanical property and erosion resistance, good in thermal shock stability and high in refractoriness under load, and can effectively prolong the service life of the submerged arc furnace when being used for the lining of the submerged arc furnace.
本发明提供了一种矿热炉用红柱石碳化硅砖及其制备方法，属于耐火材料技术领域，该红柱石碳化硅砖包括主料和辅料；所述主料以质量百分数计，包括组分：粒度小于5mm的红柱石70～75％、粒度小于1mm的碳化硅8～12％、粒度小于0.074mm的白刚玉和/或板状刚玉5～10％、改性α‑Al2O3微粉3～5％和粒度小于0.074mm的广西白泥细粉5～8％；所述辅料包括组分：结合剂糊精、掺锆氧化钛和水，其中，结合剂糊精的质量为主料质量的0.5‑0.8％，掺锆氧化钛的质量为主料质量的1‑2％，水的质量为主料质量的3‑3.5％。本发明确保制得产品力学性能和抗侵蚀性能优异、热震稳定性好、荷重软化温度高，用于矿热炉内衬，可有效延长矿热炉的使用寿命。
