Description
技术领域
本发明涉及耐磨浇注料技术领域，具体涉及一种水泥窑用低温耐磨浇注料。
背景技术
近年来，我国水泥工业发展迅速，耐磨浇注料作为水泥窑用的内衬材料得到充分重视，由于水泥回转窑窑口段的耐火内衬不仅要承受水泥熟料的强烈冲刷和磨损，且随回转窑每转一周就要经受一次(加热-冷却)温度变化，所以要求窑口段耐火内衬具有良好的耐磨性。耐磨浇注料主要指在常温和特定温度下具有良好耐磨蚀能力的浇注料，耐磨浇注料常温耐磨性的测定可以按照国家标准GB/T18301-2001(等效采用ASTMC704-1994)的试验方法进行测定，磨损量越小，表示该浇注料的耐磨性越好。耐磨浇注料在水泥熟料烧成系统中主要承受水泥生料、熟料或含尘高温气体的剧烈磨损，所以耐磨浇注料所选用的原料必须具备体积密度大、机械强度高等特点。研制一种耐磨性高的水泥窑用低温耐磨浇注料将具有好的应用前景。
发明内容
本发明的目的在于提供一种水泥窑用低温耐磨浇注料，该水泥窑用低温耐磨浇注料具有较高的耐压强度和耐磨性。
为实现上述目的，本发明的技术方案是：
一种水泥窑用低温耐磨浇注料，主要由以下质量百分数的组分组成：粒径为5-10mm的均化铝矾土骨料12％-30％，粒径为3-5mm的均化铝矾土骨料11％-28％，粒径为1-3mm的棕刚玉15％-35％，粒径为0-1mm的棕刚玉15％-25％，SiO2微粉4％-6％，均化矾土微粉8％-13％，白刚玉粉3％-6％，α-Al2O3微粉3％-6％，纯铝酸钙水泥7％-12％。
优选的，上述水泥窑用低温耐磨浇注料，主要由以下质量百分数的组分组成：粒径为5-10mm的均化铝矾土骨料12％-30％，粒径为3-5mm的均化铝矾土骨料11％-19％，粒径为1-3mm的棕刚玉15％-325％，粒径为0-1mm的棕刚玉15％-250％，SiO2微粉4％-6％，均化矾土微粉8％-11％，白刚玉粉3％-5％，α-Al2O3微粉3％-6％，纯铝酸钙水泥7％-10％。
所述水泥窑用低温耐磨浇注料还包括质量百分数为黑SiC细粉1～3％。
所述水泥窑用低温耐磨浇注料还包括质量百分数为0％～0.4％的三聚磷酸钠。
所述水泥窑用低温耐磨浇注料还包括质量百分数为0.1％～0.4％的三聚磷酸钠。
所述水泥窑用低温耐磨浇注料还包括质量百分数为0％～0.4％的柠檬酸钠。
所述水泥窑用低温耐磨浇注料还包括质量百分数为0.2％～0.4％的柠檬酸钠。
所述水泥窑用低温耐磨浇注料还包括质量百分数为0％～2％的耐热钢纤维。
所述水泥窑用低温耐磨浇注料还包括质量百分数为1％～2％的耐热钢纤维。
本发明的水泥窑用低温耐磨浇注料，主要由均化铝矾土骨料、棕刚玉、SiO2微粉、均化矾土微粉、白刚玉粉、α-Al2O3微粉、纯铝酸钙水泥组成，均化铝矾土骨料以高铝矾土为原料，先除去铝矾土有害杂质等成分，再经过破碎、提纯、配料、研磨、除铁、成型、烘干、高温烧制等步骤而形成的一种优质耐火原材料，其质地致密，晶粒发育规则，成分均匀，体积密度大，高温性能优良，使用时不需分级拣选，综合成本低；α-Al2O3微粉可以用来提高浇注料的耐火度，在高温下发生陶瓷化和莫来石化反应，根据配方需要调整α-Al2O3微粉的用量，最大限度的提高浇注料的强度和密度，降低需水率，进而提高浇注料的耐磨性；纯铝酸钙水泥作为结合剂，其主要作用时发生水化硬化反应，产生水合结合强度；SiO2微粉具有较细的粒度，且颗粒形态近球形，具有良好的流动性，填充细小空间，达到紧密堆积，同时为浇注料在高温下发生莫来石化反应提供硅质来源；另外，本发明的均化铝矾土骨料、棕刚玉均采用大小颗粒的混合，大颗粒本身能够有效抵抗磨损介质的连续冲击，颗粒越大，抵抗力越强，采用大小颗粒相结合的方法可以使得浇注料更为致密，具有更强的抗压强度，进而提高其耐磨性。
进一步的，本发明的水泥窑用低温耐磨浇注料，还包括黑SiC细粉1～3％，碳化硅不仅具有非常好的抗化学侵蚀性能，而且在高温下发生氧化还原反应，在材料表面产生SiO2玻璃状光滑物质层，更加有效地阻止了有害气体对耐磨浇注料的化学侵蚀，此外，碳化硅属于共价键化合物，强度大，耐磨性好，导热率高，还可以填补基质部分气孔从而使结构更致密，使得浇注料强度提高进而提高其耐磨性。
进一步的，本发明的水泥窑用低温耐磨浇注料，还包括0％～0.4％的三聚磷酸钠，三聚磷酸钠是作为减水剂加入的，三聚磷酸钠的加入可以减少浇注料使用过程中水的加入量，进而提高浇注料的耐磨性。当加入量过大时，加热后水分挥发逸出，留下的空隙增多，结构疏松，导致浇注料施工强度下降，耐磨性变差。用水量过多时水化反应虽能生成CAH10，但水化产物的晶型转变过程为CAH10→C2AH8→C3AH6和A·aq→AH3，CAH10和C2AH8是介稳相，有较高的强度，但易转变为稳定的C3AH6和AH3，强度随后降低。当用水量少时，水化反应就会产生较多的非晶质铝胶C3AH6和AH3，浇注料在烘干过程中不会有CAH10转变为C3AH6的反应，即不会出现晶型转变和空隙增多而造成强度下降，所以用水量少，烘干强度相应提高，耐磨性也随之提高。
进一步的，本发明的水泥窑用低温耐磨浇注料，还包括0％～0.4％的柠檬酸钠，柠檬酸钠可以提高三聚磷酸钠的减水效果，从而进一步提高浇注料的耐磨性。
进一步的，本发明的水泥窑用低温耐磨浇注料，还包括0％～2％的耐热钢纤维。在本发明的耐磨浇注料中加入耐热钢纤维，可以提高浇注料的强度、韧性、热震稳定性及耐磨性等特点。
本发明的水泥窑用低温耐磨浇注料，耐压强度高，抗折强度高，耐磨性好，使用时加水量少。这种水泥窑用低温耐磨浇注料能够满足水泥窑三次风管弯头、篦冷机矮墙等部位的长时间使用。

实验例
对实施例1-4及对比例的水泥窑用低温耐磨浇注料进行性能测试，结果如表1所示：
表1实施例1-4及对比例的水泥窑用低温耐磨浇注料的性能测试数据
由表1内容可知，实施例1中的水泥窑用低温耐磨浇注料的耐压强度、抗折强度、耐磨性等性能明显优于对比例，说明均化铝矾土骨料、棕刚玉采用不同大小的粒径能够明显提高浇注料的耐压强度、抗折强度、耐磨性；实施例2-4中的耐压强度、抗折强度、耐磨性又优于实施例1，说明黑SiC细粉、三聚磷酸钠、柠檬酸钠以及耐热钢纤维的加入能够进一步提升浇注料的耐压强度、抗折强度及耐磨性。
对本领域的技术人员来说，可根据以上描述的技术方案以及构思，做出其它各种相应的改变以及形变，而所有的这些改变以及形变都应该属于本发明权利要求的保护范围之内。
