Description
技术领域
本发明涉及一种铝合金铸造用转接管修复料及其制备方法,属于不定型耐火材料技术领域,主要应用于铝合金铸造过程使用的转接管修复。
背景技术
铝合金铸造过程中,转接管主要起从分流盘将高温铝液引入结晶器的作用,高温铝液在结晶器壁和结晶器底座的共同作用下形成一个较坚固的凝固壳,待分流盘中的铝液达到一定高度后,凝固壳在牵引装置及重力作用下被缓慢拉引出结晶器,然后经过冷却水二次冷却后完全凝固形成铸锭,铸锭长度达到规定尺寸后,停止铸造,关闭冷却水,卸下铸锭,清理转接管及分流盘,即完成一次铸造。在此过程中,需采用工具将凝固于转接管及分流盘上的铝渣清理干净。转接管采用耐火材料制作而成,在高温铝液侵蚀下其强度大幅降低,清理铝渣过程中极易损坏而不能正常使用,必须进行更换,造成转接管消耗量大,同时更换转接管过程需要消耗大量劳动时间,影响生产效率。因此,有必要开发一种铝合金铸造用转接管修复料,延长转接管使用寿命,提高铝及铝合金铸造生产效率,降低企业生产成本。
发明内容
为解决上述技术问题,本发明提供一种耐高温、粘结性好、使用寿命长的铝合金铸造用转接管修复料及其制备方法。
本发明采用的技术方案如下:
一种铝合金铸造用转接管修复料,按质量百分比由滑石粉50%~55%、氧化铝5%~8%、硅溶胶20%~25%、氮化硼12%~25%配制而成。
上述组分中,滑石粉粒度大于400目。所述氧化铝为工业级氧化铝粉。所述硅溶胶为铸造碱性硅溶胶。所述氮化硼为涂料级氮化硼。
本发明所述铝合金铸造用转接管修复料的制备方法如下:
A.按照质量百分比进行备料:滑石粉50%~55%、氧化铝5%~8%、硅溶胶20%~25%、氮化硼12%~25%;
B.将滑石粉过400~1000目筛进行筛分;
C.将筛分后的滑石粉与氧化铝、硅溶胶、氮化硼混合,搅拌均匀,得到铝合金铸造用转接管修复料。
本发明具有下列优点和有益效果:
(1)本发明的配料包括滑石粉、氧化铝、硅溶胶和氮化硼,由于硅溶胶与耐火材料粘结力较强,具有耐高温等特点,其与滑石粉、氧化铝等耐火材料共同制备成修复料,修复转接管后不易脱落,有效增加转接管使用寿命,减少转接管更换时间,提高铝合金铸造生产效率。
(2)修复料中通过加入氮化硼成分,提高了修复料对高温铝合金的润滑性,使铸造完成后产生的铝渣不易粘于修复料,提高修复料使用寿命。
(3)修复料制备工序简单,原料成分来源广泛,制作成本低。
