Ultralow-carbon magnesia carbon brick with excellent performance, and preparation method thereof
The invention provides an ultralow-carbon magnesia carbon brick with excellent performance, and a preparation method thereof. The ultralow-carbon magnesia carbon brick with excellent performance is prepared from, by mass, 70 to 110 parts of fused magnesia, 0.1 to 8 parts of composite graphitized carbon black, 0.5 to 8 parts of liquid phenolic resin, 0.1 to 8 parts of carbon/magnesium aluminate spinel composite powder and 0.1-8 parts of metal aluminum powder. Composite graphitized carbon black is added to form a nano-structure matrix in the magnesia carbon brick, nanopores can be generated in the carbonization process to improve deformation of the material caused by thermal expansion and shrinkage and increase the thermal shock stability of the material, the carbon/magnesium aluminate spinel composite powder contains extremely high ordered free carbon, addition of carbon of the low-carbon magnesium-carbon material can be reduced, and the problems that carbon of the low-carbon magnesium-carbon refractory material is difficult to disperse uniformly and prone to agglomeration are remarkably solved.
本发明提供一种性能优良的超低碳镁碳砖及其制备方法，性能优良的超低碳镁碳砖按照质量份数计算，其制备原料包括：电熔镁砂70‑110份；复合石墨化炭黑0.1‑8份；液态酚醛树脂0.5‑8份；碳/镁铝尖晶石复合粉0.1‑8份；金属铝粉0.1‑8份。性能优良的超低碳镁碳砖及其制备方法，通过加入复合石墨化炭黑，在镁碳砖中形成纳米结构基质，炭化过程中可生成纳米气孔可改善材料因热膨胀和收缩而引起的变形，提高材料热震稳定性，碳/镁铝尖晶石复合粉含有极高有序的自由碳，可减少低碳镁碳材料碳的加入，显著改善低碳镁碳耐火材料的碳难分散均匀、易团聚的问题。
