Description
技术领域
本发明涉及耐火材料技术领域，尤其涉及一种高炉主铁沟用抗氧化浇注料。
背景技术
随着高炉大型化和冶炼技术的不断提高，利用系数提升，高炉的出铁产量不断增加，通铁时间逐步延长，因而对高炉主铁沟用浇注料的性能也提出了更加苛刻的要求。由于出铁沟用耐火材料受高温铁水和渣的热态冲刷，又要受机械磨损和化学侵蚀，还不断承受温度梯度急骤变化等综合作用，因而容易产生微裂纹，这类微裂纹促使了铁水和渣的渗透侵蚀和结构破坏。高炉出铁沟主要使用Al2O3-SiC-C质浇注料、为了进一步提高主铁沟浇注料的性能和使用寿命，发明人研究了抗氧化性对Al2O3-SiC-C铁沟浇注料性能的影响。
为了进一步提高高炉出铁沟用Al2O3-SiC-C浇注料的性能和使用寿命，技术人员在不停地研究高炉出铁沟浇注料，以提高其通铁量和延长使用寿命，减少维护修补次数，降低耐火材料的损耗。技术人员基本上集中到研究各种添加物对Al2O3-SiC-C浇注料抗侵蚀、高强度等性能的影响。关于对抗氧化性能的影响主要集中在高温氧化，一般都做1000℃以上的Al2O3-SiC-C抗氧化试验研究。恰恰Al2O3-SiC-C浇注料的高温下氧化在并不最重要。因为高温下有渣铁粘附在铁沟浇注料层表面壁上，能有效阻止氧化。目前提高抗氧化的方法多集中在添加物上，常规的添加物有单质、碳化物、氮化物和硼化物以及它们的复合物，这些添加物在1000℃以下几乎不能发挥抗氧化的作用，在其在高温下氧化变成大体积的氧化物，有的是低温相而影响了抗侵蚀性。再就是改变碳结构和形貌。但是从原理上来讲，因非氧化物覆盖炭表面，这就阻止了扩散氧化而提高了抗氧化性。
目前而言，高炉出铁沟用浇注料技术配方主要采用Al2O3-SiC-C材料，主要原材料中成分纯度控制及杂质多且影响产品使用寿命；使用较多量铝酸盐水泥结合剂而影响其高温性能；颗粒级配组成简单且分布填充不均匀，造成产品堆积密度差，中低温结合强度较低及抗氧化性能较差，从而影响铁沟浇注料中高温使用过程中碳化硅部分氧化损失，从而影响产品的使用寿命。
现有技术中公开的高炉出铁沟浇注料主要包括以下几种，
1、低水泥结合出铁沟浇注料，以特级矾土、棕刚玉、白刚玉、氧化铝粉及铝酸盐水泥等为主要原料；低温强度高，高温抗折强度低。
2、无水泥出铁沟浇注料，以棕刚玉、白刚玉、氧化铝粉、硅微粉和水合氧化铝等为主要原料；采用凝聚结合，微粉量大，加水量多，造成产品密度较差，气孔率高而影响其烧结强度和耐磨性。
3、溶胶结合出铁沟浇注料，以棕刚玉、白刚玉、氧化铝微粉、硅微粉及改性硅铝溶胶等为主要原料；材料性质粘稠，气孔率高而体积密度较低，中高温耐冲刷性能较低。
现有技术所采取的技术方案中原材料粒度级配和添加剂等配方组合存在很多不完善之处，所采用的技术工艺方案中颗粒级配分布及其填充结构不均匀，从而影响堆积密度而造成产品结合强度较差，使用寿命无法达到长寿化，微粉组配缺失而影响中高温下的抗氧化性能等等各种因素从而影响其创造性及有益使用效果：因此，我们提供一种配方优化合理、制备方法简单易实现，安全型，环保型，可有效降低出铁沟耐材综合运行成本、提高大中型高炉主铁沟用浇注料抗氧化性能的耐材新产品，主铁沟浇注料使用寿命在一次通铁量可提升到20万吨以上，具有广泛的市场推广前景及应用价值。
发明内容
本发明的目的在于克服现有技术中的不足，提供一种高炉主铁沟用抗氧化浇注料。

所述黑碳化硅微粉粒度≤15μm，碳化硅含量≥98wt％。

进一步地，所述防爆裂纤维选用有机纤维，所述有机纤维熔点为95℃、所述有机纤维的长度15-20mm。
进一步地，减水分散剂是由无机减水剂三聚磷酸钠和有机减水剂FDN-A组成，所述三聚磷酸钠和FDN-A的重量比为4-7:3-5。

2)本发明技术配方通过不同性能抗氧化材料的优化组合、发挥其在不同温度阶段状态下的优特点表现，减少或避免使用了挥发性极强含碳材料及添加剂等，本发明对球状沥青材料舍弃不添加，既减少了笨及有害挥发物和碳含量的排放利用环保，又净化了铁水质量，产品制备方法简单，易于实现，可有效降低了出铁场综合运行成本、节约优质耐火原料资源，使大中型高炉出铁沟浇注料一次通铁量提升至20万吨以上。
3)本发明通过选用多孔莫来石，粒度1-3mm，球形颗粒、筒压强度高、导热系数低等特点，填充到产品结构中，可有效节能降耗，多孔莫来石具有密度小、比表面积大、低的热导率和热膨胀系数、良好的抗腐蚀性能，在高温下具有良好的机械强度和化学稳定性，多孔莫来石可以提高浇注料的抗蠕变和抗热震性。
