Hot-metal bottle lining brick and preparation method thereof
The invention discloses a hot-metal bottle lining brick which comprises the following raw materials in parts by weight: 45-55 parts of high bauxite, 10-14 parts of sintered tabular corundum, 7-14 parts of silicon carbide, 8-15 parts of andalusite, 5-10 parts of zirconite, 3-8 parts of calcined alumina micro powder, 6-8 parts of graphite, 2-4 parts of aluminum powder, 0.5-1 part of carbon black, 0.3-0.8 part of boron glass powder and 2-5 parts of phenolic resin. The preparation method comprises the following steps: (1) weighing the raw materials; (2) mixing zirconite, calcined alumina micro powder, graphite, aluminum powder, carbon black and boron glass powder to obtain premixed powder for later use; (3) firstly mixing high bauxite, sintered tabular corundum, andalusite and phenolic resin, and then adding silicon carbide and premixed powder for mixing; and (4) ageing the materials, performing compression molding, performing drying treatment, and performing sorting. According to the invention, the toughness of the matrix is improved, so that the thermal shock stability of the hot-metal ladle lining brick is improved, and the damage condition caused by stripping of the lining brick is relieved.
本发明公开了一种铁水罐衬砖，包括以下重量份的原料：高铝矾土45‑55份、烧结板状刚玉10‑14份、碳化硅7‑14份、红柱石8‑15份、锆英石5‑10份、煅烧氧化铝微粉3‑8份、石墨6‑8份、铝粉2‑4份、炭黑0.5‑1份、硼玻璃粉0.3‑0.8份和酚醛树脂2‑5份；制备方法：(1)称取各原料；(2)将锆英石、煅烧氧化铝微粉、石墨、铝粉、炭黑和硼玻璃粉混合，得到预混合粉，备用；(3)先将高铝矾土、烧结板状刚玉、红柱石和酚醛树脂混合，然后加入碳化硅和预混合粉混合；(4)困料，压制成型，干燥处理，拣选，即得。本发明提高了基质的韧性，进而改善了铁水罐衬砖的热震稳定性，缓解了由于衬砖剥落的损毁情况。
