Description

利用高炉铁沟沟盖废料制备的自流浇注料及其制备方法
技术领域
本发明涉及耐火材料技术领域,特别是一种利用高炉铁沟沟盖废料制备的自流浇注料及其制备方法。
背景技术
大中型钢铁企业每年有大量的高炉铁沟沟盖因拆炉被废弃掉,这势必会产生大量的废弃耐火材料。这些被作为垃圾的废弃耐火材料不但数量巨大,而且极难处理,除了极少数可以返回到生产线再利用外,大部分废弃耐火材料的典型处理方式就是掩埋或降级使用。这样,不但企业需要买地堆积或掩埋这些日益增多的废料,增加了生产成本,也造成了资源的极大浪费和严重的环境污染。
为降低铁沟浇注料的原料成本、响应国家节能减排的号召,将废料重新利用到铁沟浇注料中,大幅度降低原料成木,同时现有技术的浇注料配方存在着浇注料强度低、致密性能差、抗渣侵蚀性能弱等缺点,难以满足正常生产需求。
发明内容
本发明针对上述技术问题,提供一种利用高炉铁沟沟盖废料制备的自流浇注料及其制备方法,对废弃的高炉铁沟沟盖料进行回收利用,降低生产成本,同时提高浇注料浇注后的致密性和强度等性能。
为达到以上目的,本发明的自流浇注料通过以下技术方案实现:
一种利用高炉铁沟沟盖废料制备的自流浇注料,以质量份计,包括以下组分:铁沟沟盖废料15-25份,棕刚玉熟料30-60份,白刚玉10-20份,碳化硅15-25份,硅微粉4-9份,活性氧化铝粉5-10份,纯铝酸钙水泥3-8份,膨胀剂3-5份,减水剂0.5-1份,防爆剂0.05-1份。
与现有技术相比,采用上述技术方案的自流浇注料的有益效果是:本发明以废弃的高炉铁沟沟盖料为原料,从而实现了废弃耐火材料的回收利用,降低生产成本,同时配比棕刚玉熟料、碳化硅等原材料和添加剂,通过调整不同原料、各添加剂之间比例,来提高自流浇注料浇注后的致密性和强度,增强抗侵蚀性,延长铁沟沟盖的使用寿命。
进一步地,铁沟沟盖废料由粒径为5-10mm部分、粒径为3-5mm部分、粒径为1-3mm部分和粒径为0-1mm部分组成,粒径为5-10mm部分、粒径为3-5mm部分、粒径为1-3mm部分和粒径为0-1mm部分之间的质量比例为5:3:2:1。
进一步地,防爆剂由金属铝粉和有机纤维按照质量比1-2:1混合而成,使材料的抗爆裂性能完全能满足出铁沟现场烘烤条件。
进一步地,膨胀剂由铝酸钙和蓝晶石按照质量比1-3:1混合而成,通过添加复合膨胀剂,相对于单一铝酸钙膨胀剂更加有效补偿材料硬化过程中的收缩,防止开裂。
进一步地,减水剂为三聚磷酸钠、六偏磷酸钠和木质素磺酸钙的一种或几种的混合物。
进一步地,棕刚玉熟料由粒径为5-8mm部分、粒径为3-5mm部分和粒径为1-3mm部分组成。
进一步地,碳化硅由粒径为1-3mm部分和粒径为0-1mm部分组成。
进一步地,白刚玉由粒径小于0.045mm部分组成。
本发明还提供一种如上所述的利用高炉铁沟沟盖废料制备的自流浇注料的制备方法,按如下步骤进行:
1)选料:对使用后的铁沟沟盖废料进行分选,去除杂质;
2)破碎:采用颚式破碎机进行破碎;
3)筛分:将破碎好的铁沟沟盖废料进行筛分,得到5-10mm、3-5mm、1-3mm和0-1mm四种粒径规格的粉料;
4)混料:先将硅微粉、活性氧化铝粉、纯铝酸钙水泥和膨胀剂、减水剂、防爆剂进行预先混合,再将混合好的料与铁沟沟盖废料、棕刚玉熟料、白刚玉、碳化硅进行混合搅拌,混料时间为10-15分钟;
5)将混合好的浇注料抽检合格后包装入库。
与现有技术相比,采用上述技术方案的制备方法的有益效果是:该制备方法简单易操作,不仅降低了企业的生产成本,还节能环保。
具体实施方式
为了使本领域的技术人员更好地理解本发明,下面将结合具体实施例对本发明技术方案进行清楚、完整的描述。
实施例1
