Abstract

本发明提供了一种耐腐蚀性和加工性优异的基于碳化硅的浇注料。本发明提供了一种基于碳化硅的浇注料，其通过向含有60至95重量％碳化硅的100重量份耐火粉料中添加0.1至2.5重量份基于高岭土的粘土而得到。

Description

基于碳化硅的浇注料
技术领域
本发明涉及一种用于高炉出铁槽的内衬等的基于碳化硅的浇注料。
背景技术
高炉出铁槽被用作将热金属从排放金属的高炉出铁口运输的流道。由于高炉出铁槽容易受到炉渣等的化学侵蚀，因此已有使用具有高耐腐蚀性的基于碳化硅的浇注料涂布炉内表面的常见技术。
例如，专利文献1公开了一种包含大量碳化硅的不定形耐火材料。所述不定形耐火材料通过向耐火材料中引入55至90质量％的碳化硅以提高耐腐蚀性而得到。
专利文献1：特开2002-20177号公报
发明内容
本发明要解决的技术问题
然而，耐火材料中高比例的碳化硅降低了浇注料的流动性，从而导致浇注料的应用性降低。
因此，本发明的目的是提供一种耐腐蚀性和加工性优异的基于碳化硅的浇注料。
解决问题的手段
通过提供一种基于碳化硅的浇注料来实现本发明的上述目的，所述基于碳化硅的浇注料通过向含有60至95重量％碳化硅的100重量份耐火粉料中添加0.1至2.5重量份基于高岭土的粘土而得到。
发明效果
本发明提供了一种耐腐蚀性和加工性优异的基于碳化硅的浇注料。
附图说明
图1是显示本发明实施例和比较例的流动性的测定结果的图。
具体实施方式
下面描述本发明的一个实施方式。根据下述实施方式的基于碳化硅的浇注料特别适合用于高炉出铁槽的内衬。
由含有60至95重量％碳化硅的耐火材料形成所述基于碳化硅的浇注料。为了确保理想的耐腐蚀性，碳化硅的含量必须为60重量％以上；然而，高于95重量％的含量降低流动性，并且也使适当地引入其他添加剂如粘合剂变得困难。所述碳化硅可以选自市售产品，并且优选具有90％以上的纯度。而且，碳化硅的粒径分布优选为从超细粒子至约12mm的范围内以确保足够的填充密度。
除碳化硅外，所述耐火粉料例如还可以包含耐火材料，如氧化铝；碳材料，如沥青、石墨粉末或炭黑；粘合剂，如矾土水泥；抗氧化剂，如碳化硼；烧结助剂，如金属硅粉末等等。
通过向含有60至95重量％碳化硅的100重量份耐火粉料中添加0.1至2.5重量份基于高岭土的粘土来获得本发明基于碳化硅的浇注料。利用这一组成，本发明基于碳化硅的浇注料提高了流动性和抗氧化性。所述基于高岭土的粘土是由化学式Al2O3·2SiO2·2H2O表示的粘土，主要包含高岭石、地开石、珍珠陶土、埃洛石或类似矿物。也可以使用木节土和陶土。
为了形成高炉出铁槽的内衬，将所述基于碳化硅的浇注料加水混炼，并置于模板中以成形。根据需要，所述耐火粉料可以包含分散剂以提高分散效果。
如下面的实施例中所述，所述基于高岭土的粘土的含量极大地影响所得加水混炼物的流动性。更具体地说，相对于100重量份的耐火粉料，如果所述含量少于0.1重量份，那么就不能充分显示通过添加基于高岭土的粘土所给出的效果，从而无法确保理想的流动性。相反，如果所述含量多于2.5重量份，则粘度升高，从而降低流动性。因此，即使使用最小量的水，所述基于高岭土的粘土的上述含量范围也确保了理想的加工性。所以，可以形成适用于高炉出铁槽的内衬的足够致密的层。相对于100重量份的耐火粉料，添加基于高岭土的粘土的最佳量为约1.5重量份。
本发明基于碳化硅的浇注料包含少量基于高岭土的粘土，从而确保了理想的流动性。因此，不必在所述浇注料中添加二氧化硅。这也有助于耐腐蚀性的提高。
实施例1
下文中，参考以下实施例和比较例更具体地解释本发明。然而，本发明不限于这些实施例。
作为实施例1至9和比较例1至6，将表1中的原料以指定的比例混合，并与表1中指定量的水混合。混炼所述混合物。在这些实施例和比较例中，使用木节土作为基于高岭土的粘土。
Figure BPA00001187585000041
在表1中，碳化硅在耐火粉料中的比例(重量％)被设定为60、80和92.5。调整占组合物中剩余比例的氧化铝的含量和粒径，从而使所有的混合物具有均一的密度。图1示出了混合物的一部分的流动值的测定结果。根据JIS R 5201(水泥的物理测试方法)进行测定。
为了确保将浇注料流畅地提供至模具中，流动值必须为120以上。如图1中所示，相对于100重量份的耐火粉料，当基于高岭土的粘土的含量(添加百分比)在0.1至2.5重量份的范围内时，得到满意的流动性。当基于高岭土的粘土的含量为约1.5重量份时，流动性特别优异。
