Anti-skinning castable prepared from waste silicon mullite bricks and preparation process thereof
The invention relates to the technical field of refractory materials, and discloses an anti-skinning castable prepared from waste silicon mullite bricks. The anti-skinning castable comprises the following raw materials in percentage by weight: 10-50% of waste silicon mullite bricks, 10-30% of high-aluminum aggregate, 1-10% of silicon carbide, 10-20% of bauxite, 5-15% of aluminate cement, 4-8% of silica powder, 1-3% of alpha-Al2O3 micro powder, 0.1-0.5% of an additive and 2-5% of an antioxidant. The granularity composition of the waste silicon mullite bricks is as follows: 5-10% of waste silicon mullite bricks with the size of 5-3mm, 10-15% of waste silicon mullite bricks with the size of 3-1mm and 20-30% of waste silicon mullite bricks with the size of 1-0mm. According to the anti-skinning castable prepared from the waste silicon mullite bricks and the preparation process of the anti-skinning castable, the waste silicon mullite bricks are used, and the waste silicon mullite bricks consist of 5-3mm waste silicon mullite bricks, 3-1mm waste silicon mullite bricks and 1-0mm waste silicon mullite bricks, so that a new method for treating the waste silicon mullite bricks is found, and the preparation cost is effectively reduced; and moreover, the anti-skinning performance of the castable is also maintained, the adhesion of raw materials fired in a cement kiln is small, and the skinning frequency can be greatly reduced.
本发明涉及耐火材料技术领域，且公开了一种利用废旧硅莫砖制成抗结皮浇注料，包括以下重量份数配比的原料：废旧硅莫砖10‑50％、高铝骨料10‑30％、碳化硅1‑10％、铝矾土10‑20％、铝酸盐水泥5‑15％、硅微粉4‑8％、α‑Al2O3微粉1‑3％以及添加剂0.1‑0.5％和抗氧化剂2‑5％；所述废旧硅莫砖的粒度组成为：5‑3mm废旧硅莫砖5‑10％、3‑1mm废旧硅莫砖10‑15％和1‑0mm废旧硅莫砖20‑30％。该利用废旧硅莫砖制成抗结皮浇注料及其制作工艺，通过使用废旧硅莫砖，且废旧硅莫砖由5‑3mm废旧硅莫砖、3‑1mm废旧硅莫砖和1‑0mm废旧硅莫砖组成，不仅为处理废旧硅莫砖寻找了一种新的方法，也有效的降低了制作成本，而且还保持该浇注料的抗结皮性能，水泥窑烧制生料黏附性小，能大幅度降低结皮次数。
