Unfired magnesia-calcium brick for AOD (Argon Oxygen Decarburization) furnace and preparation method thereof
The invention discloses an unfired magnesia-calcium brick for an AOD (Argon Oxygen Decarburization) furnace. The unfired magnesia-calcium brick is prepared from the following raw materials in percentage by weight: 7-12% of 8-5mm magnesia-calcium sand, 12-20% of 5-3mm magnesia-calcium sand, 15-25% of 3-1mm magnesia-calcium sand, 7-15% of 1-0mm magnesia-calcium sand, 5-15% of 1-0mm high-purity magnesia, 15-25% of 0.088-0 mm high-purity magnesia, 2-4% of anhydrous resin and 0.5-1% of a composite additive. The unfired magnesia-calcium brick for the AOD converter has the beneficial effects that the unfired magnesia-calcium brick for the AOD converter, which is prepared through reasonable burdening and an advanced treatment process, is high in density and high in compression strength; in addition, the product adopts high-purity magnesite clinker as a matrix, and meanwhile, a composite additive for promoting sintering is added, so that the product is high in anti-scouring capacity, good in high-temperature stability and long in service life, can be suitable for a plurality of parts such as an AOD converter bottom, a molten pool, a furnace crown and the like for stainless steel smelting, and can be suitable for being used under various harsh operation conditions.
本发明公开了一种AOD炉用不烧镁钙砖，由以下原料按重量百分比配制而成：8‑5mm的镁钙砂7‑12％、5‑3mm的镁钙砂12‑20％、3‑1mm的镁钙砂15‑25％、1‑0mm的镁钙砂7‑15％、1‑0mm的高纯镁砂5‑15％、0.088mm‑0的高纯镁砂15‑25％、无水树脂2‑4％、复合添加剂0.5‑1％。本发明的有益效果是，本发明经过合理的配料和先进的处理工艺，制备的该AOD转炉用不烧镁钙砖密度大，耐压强度高；并且本产品采用高纯烧结镁砂作为基质，同时添加了促进烧结的复合添加剂，使产品抗冲刷能力强，高温稳定性好，使用寿命高，能适用于不锈钢冶炼的AOD转炉炉底、熔池、炉帽等多个部位，能适应在多种苛刻操作条件下的使用。
