Description
技术领域
本发明涉及浇注料技术领域,具体为高铝质纤维浇注料。
背景技术
浇注料又称耐火浇注料,是一种由耐火物料加入一定量结合剂制成的粒状和粉状材料,具有较高流动性,以浇注方式成型的不定形耐火材料,同其他不定形耐火材料相比,结合剂和水分含量较高,流动性较好,故而浇注料应用范围较广,可根据使用条件对所用材质和结合剂加以选择,既可直接浇注成衬体使用,又可用浇注或震实方法制成预制块使用;
浇注料的种类多种多样,高铝质纤维浇注料也是其中一种,现如今市面上的高铝质纤维浇注料结构强度较差,在工作或者运输过程中容易受到碰撞和冲击,极易造成浇注的成品破裂,大大缩短了使用寿命,同时高铝质纤维浇注料应用在高温窑炉、热风炉中,工作环境温度高、盐分高,对浇注层的耐高温性能要求极高,同时高盐分的环境会浇注层腐蚀的现象出现,并且现有的技术骨料不分级,水泥用量大且颗粒粗,水泥无法完全水化,增大了浇注料的空隙,大大降低了浇注料的品质。
发明内容
本发明的目的在于提供高铝质纤维浇注料,以解决上述背景技术中提出的问题。
为实现上述目的,本发明提供如下技术方案:高铝质纤维浇注料,配方包括:一级高铝矾土骨料、二级高铝矾土骨料、耐火纤维、氧化铝粉末、高强纤维、氧化铬、硅灰、高铝水泥、矾土熟料、三聚磷酸钠和减水剂,各组分的重量份数分别是:45-50份的一级高铝矾土骨料、20-25份的二级高铝矾土骨料、5-7份的耐火纤维、8-10份的氧化铝粉末、2-3份的高强纤维、2-5份的氧化铬、3-5份的硅灰、5-7份的高铝水泥、10-15份的矾土熟料、0.1-0.2份的三聚磷酸钠和0.1-0.2份的减水剂。
优选的,所述一级高铝矾土骨料得粒度为3-5mm。
优选的,所述二级高铝矾土骨料的粒度为1-2mm。
优选的,所述耐火纤维为石棉纤维和陶瓷纤维按照1∶1的重量份数之比混合而成。
优选的,所述高强纤维为钢纤维和碳纤维按照10∶1的重量份数之比混合而成。
优选的,所述矾土熟料的粒度为0.5-1mm。
与现有技术相比,本发明的有益效果是:
1.本发明通过将陶瓷纤维和石棉纤维作为耐火纤维添加到配方中,增强了浇注料的耐高温能力,同时配方中加入氧化铬,氧化铬增加了浇注料的结晶度,并且浇注料的结合更加紧密,有利于提升浇注料的耐腐蚀能力,有效的延长了浇注料在高温、高盐分下的使用寿命;
2.本发明通过氧化铝、钢纤维和碳纤维的加入,增强了浇注料的结构强度,避免了冲击和碰撞导致的浇注料破裂脱落的现象发生;
3.本发明通过对骨料进行分级,添加不同粒度的骨料,保证了浇注料的粒径均匀,同时减少了水泥的用料,有利于保证浇注料具有高致密度,同时降低了浇注料的孔隙率,提升了浇注料的质量。
