一种高导热高耐磨耐火材料及其制备方法
技术领域
本发明属于耐火材料领域，涉及一种用于还原炉、焦炉、石油焦煅烧炉等隔焰加热的工业窑炉的主体耐火材料，特别涉及一种高导热高耐磨耐火材料。
背景技术
目前还原炉、焦炉、石油焦煅烧炉等隔焰加热的工业窑炉的主体耐材多选用高铝砖、硅砖等铝硅系产品，此类产品由于晶像多是氧化铝及氧化硅，这两种晶像自身导热能力、抗耐磨性较差，所以其制品同样存在这样的问题，导致工业窑炉热效利用率低，使用寿命短。
发明内容
为解决背景技术中存在的高铝砖、硅砖等导热系数低、耐磨性差等问题，本发明提供了一种高导热高耐磨耐火材料及其制备方法。
首先本发明提供了一种高导热高耐磨耐火材料的制备方法，其原料主要为以下质量份数的物质：
前述原料与水均匀混合后，塑型，在1450℃～1500℃温度下烧结而成。
优选地，所述碳化硅为绿碳化硅。
优选地，所述分散剂为羧甲纤维素钠或三聚磷酸钠。
优选地，所述耐火材料原料与水均匀混合均匀后，采用注浆法或挤压法成型。。
优选地，所述耐火材料主要晶相为α碳化硅，气孔率≤2％，1000℃下导热系数能够达到40～45W/(m.k)，荷重软化温度为1680℃以上。
在本发明所述高导热高耐磨耐火材料的另一种制备方法实施方式中，所述碳化硅为黑碳化硅。
优选地，所述耐火材料原料在混合均匀后，采用机械压力机机压成型。
优选地，所述耐火材料主要晶相为α碳化硅，气孔率≤10％，1000℃下导热系数能够达到35～40W/(m.k)，荷重软化温度为1680℃以上。
优选地，本发明所述高导热高耐磨耐火材料制备方法中，所述烧结过程在气氛炉内进行，所述气氛炉内为0.2MPa～0.3MPa氮气环境或氩气环境。
本发明还请求保护以上各种制备方法制备的高导热高耐磨耐火材料。
本发明所述耐火材料制品采用碳化硅、碳黑、金属硅作为主要原材料，加入分散剂，用注浆法或挤压成型，在气氛炉内(氮气、真空或氩气环境中)1450℃～1500℃温度下烧结而成。该制品由导热性能较好的原材料构成，主要晶相为α碳化硅，气孔率≤2％，均匀致密，具有较好的导热性，1000℃下导热系数能够达到35～45W/(m.k)左右，比现有单纯的碳化硅制品高出100％以上，莫氏硬度略高于刚玉硬度，具有较高的耐磨性能，耐高温性能好，荷重软化温度能够达到1680℃以上。
该耐火材料制品具有较高的导热性能和耐磨性，导热性能是硅砖20～25倍、高铝砖15～20倍，能够大幅提高隔焰加热工业窑炉的热效能利用率，减少燃料投入；耐磨性能是硅砖及高铝砖的10倍以上，能够有效的提高窑炉使用寿命，能够带来良好的经济和社会效益。
