Description
技术领域
本发明涉及钢包永久衬、铁水包永久衬，尤其涉及一种抗侵蚀的铝酸钙浇注料。
背景技术
长期以来，无论是钢包永久衬还是铁水包永久衬均采用高铝质、铝镁质浇注料或是高铝砖，此类浇注料体积密度较高，导致钢包、铁水包增重较大，加重了天车运行载荷，同时由于密度较高，导致材料的导热系数增大，使得钢水、铁水的温度降的很快，对保温节能尤为不利，增大了炼钢厂的热消耗，大量的热量被浪费消耗掉，甚至由于温降厉害，还会导致出钢困难等一系列事故的发生。如果是采用高铝砖砌筑永久衬，永久衬由于砖缝的缘故，无法成为一个整体，一旦工作衬被钢渣击穿，永久衬因为有砖缝的缘故，极易造成穿包事故，对炼钢厂造成巨大的损失，采用高铝砖砌筑永久衬由于其自身的效率低下，工作进度慢，目前已经不适应快节奏的炼钢需求。
鉴于上述原因，现研发出一种抗侵蚀的铝酸钙浇注料。
发明内容
本发明的目的是为了克服现有技术中的不足，提供一种抗侵蚀的铝酸钙浇注料，不仅施工速度快，体积密度也低，抗钢渣和钢水的侵蚀能力也强，起到了节能减排，保安全等方面的作用。
本发明为了实现上述目的，采用如下技术方案：一种抗侵蚀的铝酸钙浇注料，所述的铝酸钙浇注料的各组分的重量百分比为：铝酸钙骨料和细粉的混合物：65-69.9％，氧化铝空心球占比为10-13％，纯铝酸盐水泥占比为2-10％，氧化铝微粉占比为5-11％，添加剂为0.5-3％，高效分散剂为0.1％；以上各组分的组配重量之和为100％。
本发明的有益效果是：铝酸钙骨料中的三氧化二铝含量为85％，氧化钙含量为10％，体积密度为2.80g/cm3,显气孔率为25％，铝钙含量好，抗渣侵蚀能力强，而体积密度小，气孔率高，使得材料比重很轻，材料内部的气孔多，保温性能很好，氧化铝空心球的体积密度为0.7g/cm，添加的铝酸盐水泥可以起到增加强度的目的，使得材料抗冲刷、撞击能力提高，氧化铝微粉由于很细，使得材料整体流动性极好，添加剂可以使得材料再收到高温时，出现微膨胀，有利于保证材料的整体性；本发明的铝酸钙浇注料不仅施工速度快，体积密度也低，抗钢渣和钢水的侵蚀能力也强，起到了节能减排，保安全等方面的作用。
具体实施方式
下面结合实施例与具体实施方式对本发明作进一步详细说明：
