Description

铁水罐工作层用铝碳化硅碳砖
技术领域
本发明涉及耐火材料，尤其是涉及一种铁水罐工作层用铝碳化硅碳砖。
背景技术
铁水罐是钢铁联合企业重要的铁水输送设备，负责将炼铁厂高炉生产的铁水盛装运输至炼钢厂。因为铁水温度高、运输距离长，所以对于铁水罐的安全性和耐用性均有很高的要求，而工作层材料决定着铁水罐的安全性和使用寿命。铁水罐工作层用耐火砖是直接接触铁水的，因此要求使用的耐火砖具有砌筑方便、结构稳定、耐冲刷、耐侵蚀、热振性能好、使用周期长等性能。目前铁水罐使用的耐火砖主要以Al2O3-SiC-C的复合材质制作，由于该产品在钢铁企业生产过程中消耗量大，导致原材料成本较高。
对用后耐材进行合理的回收利用，不仅能大大减少原材的消耗量，也可减少工业固废对生态环境造成的破坏。目前世界各国都开展了对用后耐火材料的研究，国外有些钢厂的耐火材料回收利用率达到了80%，而我国对用后耐材的回收率仅为30%左右，远低于发达国家。
鱼雷罐衬砖、铁水沟浇注料、碳化硅板、叶腊石碳化硅碳砖等均是冶炼行业常用的耐材，在对设备进行保养和维修时，一些用后的耐材被更换废弃，如果能将这些回收耐材加以应用，则可大大降低铁水罐的原材料成本。
发明内容
本发明的目的在于针对现有铝碳化硅碳砖原材料成本高的缺陷，提供一种利用回收的耐火材料作为原材料配制的铁水罐工作层用铝碳化硅碳砖，既降低了铁水罐的原材料成本，同时也减少了工业固废排放对生态环境的破坏。
为实现上述目的，本发明可采取下述技术方案：
本发明所述的铁水罐工作层用铝碳化硅碳砖，是由回收的鱼雷罐衬砖、铁水沟浇注料、碳化硅板、叶腊石碳化硅碳砖和成品原料二级铝矾土、叶腊石、鳞片石墨、粘土粉和混合油结合剂按下述重量份配比配制而成：
回收鱼雷罐砖0～50份，其中粒度1~8mm的颗粒料0～35份，200目粉料0～15份；
回收铁水沟浇注料0～50份，其中粒度1~8mm的颗粒料0～35份，200目粉料0~15份；
回收碳化硅板5～7份，120目粉料；
回收叶蜡石碳化硅碳砖6～13份，粒度0～1mm颗粒料；
二级铝矾土11～21份，其中1～8的颗粒料6～13份，200目粉料5～8份；
粒度1～3mm叶蜡石颗粒料8～15份；
鳞片石墨3～6份，100目粉料；
200目粘土粉5～7份；
结合剂按物料总量的3～7%添加。
其中回收鱼雷罐砖和回收铁水沟浇注料不能同时为零。
为保证配制的铝碳化硅碳砖的质量满足使用要求，对所用回收料和原料的质量要求如下：
本发明所用的回收鱼雷罐砖中Al2O3≥55%，SiC≥8%，C≥4%，Fe2O3≤2.5%。
本发明所用的回收铁水沟浇注料中Al2O3≥55%，SiC≥12%，C≥3%，Fe2O3≤2.5%。
本发明所用的回收碳化硅板中SiC≥80%。
本发明所用的回收叶蜡石碳化硅碳砖中Al2O3≥35%，SiC≥10%，C≥5%。
本发明所用的二级铝矾土中Al2O3≥75%。
本发明所用的叶蜡石中Al2O3≥14%，SiO2≥68%，水份≤3。
本发明所用的鳞片石墨中C≥90%。
本发明所用的粘土粉中Al2O3≥30%，SiO2≥50%，水份≤3%。
本发明所用的结合剂为酚醛树脂或者磷酸二氢铝；其中酚醛树脂25℃粘度8000~12000mpa·s，固体含量≥80%，残碳≥40%，ph值6~8；磷酸二氢铝密度1.4~1.5g/cm3，固体不溶物≤1.0%。
首先将回收的鱼雷罐衬砖、铁水沟浇注料、碳化硅板、叶腊石碳化硅碳砖进行成分检测，满足使用要求后，进行拣选，去除杂质，分别粉碎至设计粒度；与成品原料二级铝矾土、叶腊石、鳞片石墨、粘土粉按比例添加进混碾机中搅拌均匀，再加入结合剂进行充分混碾，采用400吨压力机按设计图纸制成半成品，入烘干房在120～350℃烘烤后即获得成品，正常包装储存。
本发明的优点在于较大比例的使用用后回收耐火材料，大大节约了原生耐火材料资源的使用，降低了原料成本，减少了耐火材料工业固废垃圾破坏环境，符合国家资源循环利用的产业政策。并且所选用回收材料的材质均优于正常生产铁水罐砖的材料材质，提高了铁水罐工作层用铝碳化硅碳砖的性能。该产品经客户现场使用，表现出砌筑方便、结构稳定、耐冲刷、耐侵蚀、热振性能好、使用周期长等优异品质。
具体实施方式
下面通过具体实施例对本发明做更加详细的说明，以便于本领域技术人员的理解。
本发明所用的回收耐材，包括鱼雷罐衬砖、铁水沟浇注料、碳化硅板、叶腊石碳化硅碳砖，均为本行业作为固废的用后耐材，用时需先进行成分检测，满足组分要求后才可使用；成品原料二级铝矾土、叶腊石、鳞片石墨、粘土粉以及结合剂酚醛树脂或者磷酸二氢铝均为市售产品。
本发明按照下表1列举出四个配制实例：
表1

对上述1~4#成品砖进行检测，其理化指标如下表2：
表2
Figure 931378DEST_PATH_IMAGE002
目前铁水罐工作层用耐火砖的各项指标范围如下表3：
表3
Figure DEST_PATH_IMAGE003
将表2、表3数据对比可以看出，本发明制备的铁水罐工作层用铝碳化硅碳砖可完全满足钢铁厂对于铁水罐转运铁水使用的要求。
由于转运铁水的种类不同，实际配制时，可以根据用户实际需求，对所用原材料的加入比例进行调整（在本发明公开的范围内进行调节，如配制时也可以同时加入回收鱼雷罐砖和回收铁水沟浇注料，两者配合使用），目的使成品铝碳化硅碳砖的化学成份符合转运铁水的使用要求即可。
