Description
技术领域
本发明涉及一种耐火浇注料内衬材料，具体涉及一种不污染高强铝合金的耐火浇注料。
背景技术
硬铝合金主要是以Al-Zn-Mg-Cu系为主的合金。由于硬铝合金具有密度低、强度高、加 工性能好及焊接性能优良等特点，被广泛应用于航空工业及民用工业等领域。我国从20世 纪60年代开始即对航空航天用硬铝合金材料进行了深入系统的研究，开发了上百种铝合金 材料，基本跟上了世界步伐，有些研究成果达到了国际先进水平，也基本上满足了我国航空 航天及军工需要。总的讲，我国铝合金的研制主要跟踪国际先进水平，但关键技术的突破以 及品种、规格的系列化发展和工程应用水平距离国外还有较大差距，其中，硬铝合金的整体 研发和生产等方面还比较欠缺。铝合金材料的冶金质量一直是困扰铝加工企业和航空工业的 老大难问题。为了达到航空航天器对铝合金材料极高的冶金质量要求，熔铸企业需要确保耐 火内衬等材料对铝合金熔液的不污染，以生产出满足技术要求的铸锭。由于硬铝合金中Al、 Mg、Zn具有较高的化学活性，炉子的内衬材料对铝液有污染，在熔化和铸造的工艺过程中， 高强铝合金非常容易被污染，此外，硬铝合金熔化炉、保温炉的耐火材料极易遭到破坏，如 耐火材料剥落或被侵蚀形成镁铝尖晶石，而造成耐火材料体积膨胀，严重时会使炉体结构严 重变形。目前炉衬材料多为氧化物，如高铝矾土、刚玉等材料。这些氧化物与高强铝合金中 的Al、Mg、Zn等会发生强烈的反应：4Al(l)+3SiO2(s)→2Al2O3(刚玉结瘤)+3Si(l)； 4Al(l)+3Al2O3·SiO2(s)→5Al2O3(刚玉结瘤)+3Si(l)；2Al+Fe2O3→Al2O3+2Fe； 2Mg+SiO2→2MgO+Si(增硅)；3Mg+4Al2O3→3MgAl2O4(镁铝尖晶石)+2Al；2Al+Fe2O3 →Al2O3+2Fe；2Zn+SiO2→2ZnO+Si由以上氧化物构成的炉衬材料，不但易于损坏，而 且反应生成的Si、Fe等进入铝液中，使熔体受到污染。因此，对于高强铝合金的炉衬材料 选材，相比传统材料和用于一般铝及铝合金的炉衬材料要更严格。
