Description

一种钛增强刚玉系耐火材料及制备方法
技术领域
本发明涉及制备一种新型耐火材料，尤其涉及一种钛增强刚玉耐火材料制备方法，属于耐火材料领域。
背景技术
金属钛因具有密度小、比强度高、耐腐蚀性好等优点，在航空航天、石油、化工、冶金等众多领域都有重要应用。它的制备方法有很多种，常见的有卤化钛还原分解法、钛化合物电解法、氧化钛还原法。其中氧化钛还原法是在TiO2富集物料中，添加比钛更活泼的金属，实现氧化钛的脱氧。金属铝来源广，价格低，常被选用为金属钛生产过程中的还原剂。通过高温下的反应TiO2+Al＝Ti+Al2O3来实现金属钛的冶炼。金属钛熔点较低会与高熔点的反应渣Al2O3和未反应的TiO2分离，因Al2O3熔点过高，会夹杂大量的金属钛，在冶炼过程中会添加石灰，生成铝酸钙低熔点相，减少金属夹杂。
用上述方法冶炼金属钛产生的矿渣含钛铝酸钙的应用价值较低，不利于环保要求的二次利用。本发明涉及的金属钛冶炼过程，以金属铝为还原剂，但不在生产过程中添加石灰水，而是将Al2O3、TiO2、金属Ti混合的矿渣在高温电炉下加热，以减少金属钛的夹杂。以此得到一种钛增强的刚玉材料。
在刚玉系材料中添加TiO2，可以得到钛酸铝增强相。该相熔点高、线膨胀系数低，对金属铝液、钢液、铜渣和钢渣具有优良的抗侵蚀性以及抗碱性材料腐蚀。在刚玉系材料中添加金属钛，在氮气低氧分压条件下可生成非氧化物增强相TiC、TiN和Ti(C,N)。这些相都具有熔点高、热膨胀系数小、化学稳定性高、耐腐蚀、与金属润湿性差等优点。即在刚玉系材料中添加TiO2或金属钛对材料性能有较大提升。但TiO2和金属钛价格都相对昂贵，该复合材料成本较高。
