Preparation method of alumina-magnesia carbon brick
The invention discloses a preparation method of an aluminum magnesia carbon brick, and relates to the technical field of refractory materials. The invention relates to a preparation method of an aluminum-magnesia carbon brick. The aluminum-magnesia carbon brick is prepared from the following raw materials in parts by weight: 25 parts of recycled aluminum-magnesia carbon brick particles; 60 parts of 95 brown aluminum oxide; 8 parts of 97 fused magnesite; 11 parts of sub-white corundum; 8 parts of graphite-195; 3 parts of resin; and 2 parts of silicon powder. The preparation method of the alumina-magnesia carbon brick comprises the following steps: S1, carrying out preliminary crushing treatment; S2, screening in a vibrating screen; S3, carrying out secondary crushing treatment; S4, carrying out centrifugal separation by using a centrifugal machine; S5, performing soaking and drying treatment; S6, adding the raw materials into a sand mixer for mixing; S7, carrying out drying treatment. According to the method, the waste alumina-magnesia carbon bricks are pretreated, and the waste alumina-magnesia carbon bricks are separated by using a centrifugal machine according to the characteristic that the densities of the waste alumina-magnesia carbon bricks and impurities in the waste alumina-magnesia carbon bricks are different, so the removal effect is achieved, the impurity components in the waste alumina-magnesia carbon bricks are reduced, and the strength of the finally prepared alumina-magnesia carbon bricks better meets the standard.
本发明公开了一种铝镁碳砖的制备方法，涉及耐火材料技术领域。一种铝镁碳砖的制备方法，铝镁碳砖由以下重量份的原料制成：回收铝镁碳砖颗粒：25；95棕刚玉：60；97电熔镁砂：8；亚白刚玉：11；石墨‑195：8；树脂：3；硅粉：2。铝镁碳砖的制备方法包括如下步骤：S1:进行初步破碎处理；S2:放入振动筛中筛选；S3:进行二次破碎处理；S4:利用离心机进行离心法分离；S5:进行浸泡干燥处理；S6：原料加入混砂机进行混炼；S7:干燥处理；本发明通过对废弃铝镁碳砖的预处理，利用废弃铝镁碳砖与其中杂质的密度不同的特点，用离心机使其发生脱离，从而达到了去除的效果，减少了其中的杂质成分，使得最终制得的铝镁碳砖的强度更加的符合标准。
