Low-carbon aluminum silicon carbide carbon brick containing nanocarbon and preparation method thereof
The invention discloses a nanocarbon-containing low-carbon aluminum silicon carbide carbon brick and a preparation method thereof. The brick comprises high bauxite clinker with two granularities, brown fused alumina with two granularities, sub-white fused alumina, dispersible nanocarbon and the like. Through the application of the nano-carbon film and the dispersible nano-carbon, which are none, partially or completely coated on the surfaces of particles of three raw materials, comprising high-alumina bauxite clinker, brown fused alumina and sub-white fused alumina; the oxidation resistance ofthe nano-carbon is improved by utilizing the characteristics that the nano-carbon film and the dispersible nano-carbon are mainly amorphous carbon, contain a small amount of graphite chicks, can be infiltrated by a solvent and the like; therefore, infiltration and adsorption of the nano carbon film and the dispersible nano carbon to the organic binding agent are improved, the uniform dispersion of the nano carbon in the magnesia carbon brick is realized; finally, the size of carbon particles in the aluminum silicon carbide carbon brick is greatly reduced through the size control of the thickness of the nano carbon film and the dispersible nano carbon, so that the contact frequency of the refractory raw material of the aluminum silicon carbide carbon brick and the carbon particles is obviously improved, and the performance of the carbon particles under the condition of low carbon content is ensured.
本发明公开了一种含纳米碳的低碳铝碳化硅碳砖及制备方法，包括两种粒度的高铝矾土熟料、两种粒度的棕刚玉、亚白刚玉、可分散性纳米碳等。通过全不、部分或全部高铝矾土熟料、棕刚玉和亚白刚玉三种原料颗粒表面包覆的纳米碳膜、可分散性纳米碳的应用，利用纳米碳膜和可分散性纳米碳主要为无定型碳、含有少量石墨雏晶、溶剂可浸润等特点，提高纳米碳的抗氧化性，改善纳米碳膜与可分散性纳米碳对有机结合剂的浸润吸附，实现纳米碳在镁碳砖中的均匀分散，通过纳米碳膜与可分散性纳米碳厚度的尺度控制，大幅度降低铝碳化硅碳砖中碳粒子的尺度，显著提高了铝碳化硅碳砖耐火原料与碳粒子的接触频率，保证了低碳含量条件下碳粒子性能的发挥。
