Impact-corrosion-resistant shaped refractory material
The invention relates to the technical field of refractory materials, and discloses an impact-corrosion-resistant shaped refractory material. The shaped refractory material is prepared from the following raw materials in parts by weight: 25 to 30 parts of kaolin, 10 to 15 parts of silica sand, 8 to 12 parts of aluminum oxide, 9 to 14 parts of chromium oxide, 8 to 10 parts of glass powder, 12 to 14 parts of graphite, 50 to 60 parts of water, 6 to 8 parts of corundum, 4 to 5 parts of fused mullite, 8 to 9 parts of silicon dioxide powder and 10 to 15 parts of inorganic compound. The silicon dioxide powder can be used for filling pores in the refractory material, so that the sintering performance of the brick body is improved, and the density and the strength of the brick body are improved; by adding silica sand and aluminum oxide, the refractory material has excellent high-temperature resistance, acid and alkali corrosion resistance and the like, and graphite can be used for reducing friction force among the raw materials, so that the density and strength of the refractory material are improved.
本发明涉及耐火材料技术领域，公开了一种抗冲击腐蚀的定型耐火材料，定型耐火材料包括以下重量份组分原料：高岭土25‑30份、硅砂10‑15份、氧化铝8‑12份、氧化铬9‑14份、玻璃粉8‑10份、石墨12‑14份、水50‑60份、刚玉6‑8份、电熔莫来石4‑5份、二氧化硅粉8‑9份、无机化合物10‑15份，采用二氧化硅粉具有较好的抗化学腐蚀的性能，从而减缓耐火砖在高温下与酸、碱性介质接触时的腐蚀速度，提高其腐蚀性，同时二氧化硅粉可填充耐火材料内部的孔隙，从而改善砖体的烧结性能，提高密度与强度；硅砂与氧化铝的加入可使得耐火材料具有优异的耐高温、耐酸碱腐蚀等性能，石墨可用来减少原料之间的摩擦力，提高耐火材料的密度与强度。
