技术领域
本发明涉及加热炉炉底施工及维修用料技术领域，特别是指一种加热炉用长寿命抗渣耐火浇注料及其制备方法。
背景技术
目前加热炉炉底普遍采用高铝砖或者高铝浇注料。由于在加热炉运行过程中炉底部位要经受钢坯的磨损和钢坯表面掉落的氧化铁皮熔渣的渗透而导致炉底部位耐火材料损坏严重导致炉底高低不平，影响钢坯质量。目前炉底耐火材料普遍使用寿命为1年左右，加热炉检修周期较短，影响钢坯产量。
发明内容
本发明提出一种加热炉用长寿命抗渣耐火浇注料及其制备方法，解决了现有技术中抗渣耐火浇注料耐磨性低、使用寿命短的问题。
本发明的技术方案是这样实现的：一种加热炉用长寿命抗渣耐火浇注料，其特征在于，包括如下重量份的成分：
优选的，所述刚玉为棕刚玉或白刚玉或板状刚玉的一种或几种，其粒径大于325目。
优选的，所述莫来石为烧结莫来石或电熔莫来石，其粒径大于325目
优选的，所述水泥为70水泥或925水泥，其粒径小于0.1mm。
优选的，所述致密填充剂选自氧化铝微粉、碳化硅微粉、二氧化硅微粉中的一种或几种，其粒径小于0.1mm。
优选的，所述减水剂为三聚磷酸钠或六偏磷酸钠，其粒径小于1mm。
优选的，包括如下重量份的成分：
本发明提供长寿命抗渣耐火浇注料中，Al2O3含量大于60％，体积密度大于2.60g/cm3，该长寿命抗渣耐火浇注料具有优异的导热性能和耐压强度。
本发明又提出一种加热炉用长寿命抗渣耐火浇注料的制备方法，包括以下步骤：
按配方取各原料，在常温下混合后搅拌均匀，即得。
本发明的有益效果：
本发明通过选用高耐磨性的刚玉和莫来石材料提高材料的耐磨性，并通过添加致密填充剂提高材料的致密度，阻止氧化铁皮熔渣的渗透，提高材料的使用寿命。
本发明提供的长寿命抗渣耐火浇注料可以应用于工业窑炉底部部位施工或维修。所述加热炉为本领域常用窑炉，如轧钢环形加热炉。
将本发明所述长寿命抗渣耐火浇注料应用于加热炉炉底部位，材料寿命可达4年以上。
与现有技术相比，本发明提供长寿命抗渣耐火浇注料强度高、致密度高、耐磨损，使用寿命长。
