Description
技术领域
本发明属于耐火材料领域，特别涉及一种铬刚玉砖的生产方法，特别涉及一种抗还原反应、抗热震的有色金属冶炼烟化炉或侧吹炉用铬刚玉砖的生产方法。
背景技术
有色金属窑炉用耐火材料工作环境恶劣，尤其是一些领域的窑炉，如炼铅、锌、锡的烟化炉、侧吹炉，对耐火材料的要求更高，要求有高的常温耐压强度，高抗冲刷能力，高抗还原能力，高抗热震性能，高的性价比。这些都原耐火材料—镁铬质耐火材料不预备的。而现有的普通铬渣耐火材料均存在抗还原反应及热震稳定性较差的问题，无法满足这些窑炉的使用要求。
铬刚玉是用工业氧化铝与氧化铬绿电熔生产的，或是用铝热法生产金属铬的副产品铝铬渣，经过高温处理，氧化铝变成高温溶液与部分未被还原的氧化铬形成的固熔体，即为铬刚玉。铬渣主要矿物组成为α-Al2O3和Cr2O3的固熔体，其中Al2O3+Cr2O3质量百分含量一般≥90％，是一种抗侵蚀性能优秀的耐火材料。

本发明的有益效果：
1、以铬渣、板状刚玉(烧结刚玉)、铬精矿、电熔锆莫来石为主要原料，先将原料进行预处理，将铬渣、板状刚玉、铬精矿三种材料采用电熔合成法得到铬刚玉材料，在高温熔炼的过程中形成铝铬连续固熔体，促进制品致密化，提高抗熔渣的侵蚀性能，而且将有害杂质元素去除，在高温熔炼的条件下，碱性氧化物挥发掉，铬渣中残留的金属铬和铬精矿中的氧化铁会因比重较大沉降在炉缸底部形成铬的碳化物，使铬刚玉材料纯净化、致密化，且因使用固体废渣—冶炼铬渣，成本低廉，性价比高；
2、同时引入电熔锆莫来石，可以有效提高制品热震稳定性和抗剥落性能，因经过高温冶炼后产品氧化铁含量低，制品的抗还原效果好；制得的铬刚玉砖热震稳定性(风冷)≥50次，能满足有色冶金炉窑特殊部位的使用要求，可以用于炼铅、锌、锡等有色金属窑炉渣线部位、底部及反应带。制得的铬刚玉砖的化学成分和理化指标如表1所示：

实施例1～实施例3中的板状刚玉与烧结刚玉可以相互替换。
实施例1～实施例3制得的铬刚玉砖化学成分和理化指标如表2所示：
表2
从表2可以看出，本发明的铬刚玉砖热震稳定性较高，做到了在不降低常温耐压强度等指标的前提下，达到了风冷50次以上，在温度变化较大的窑炉里使用，可以大幅提高使用寿命，降低制品因不耐温度急剧变化而产生的热剥落。
在炼铅、锌的烟化炉或侧吹炉使用时，窑炉内有大量的C，会与砖内的氧化铁发生还原反应，形成单质铁和气体，从而破坏砖的结构，造成砖体损坏；本发明所涉及的产品中氧化铁含量低，在窑炉上使用时，可有效抗还原反应的发生，进而延长砖的使用寿命。在炼铅的烟化炉上，一直使用的是镁铬质耐火材料，使用寿命在6-7个月，使用本产品炉期可达1年以上。
以上仅为本发明的具体实施例而已，并不用于限制本发明，对于本领域的技术人员来说，本发明可以有各种更改和变化。凡在本发明的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本发明的保护范围之内。
