摘要
根据耐火材料和水泥熟料的反应机理,找到一种既可阻止窑皮中C2S相变,又不损害镁铝质耐火材料的高温性能的添加物,开发了一种基于MgO-MgAl2O4-ZrO2-La2O3体系的新型复合耐火材料。该材料具有优异的耐火性能、抗热震性能、挂窑皮性能、抗侵蚀性能和较高的机械强度,是一种替代镁铬砖的理想材料,适用于水泥窑烧成带。
In order to find an additive for modifying the property of magnesia-alumina spinel refractory,MgO-MgAl2O4-ZrO2La2O3 composite refractory was invented based on the reaction mechanism of spinel refractory with cement clinker.This additive could not only stabilize the phase transition of C2S in kiln brick coating,but also keep high temperature property of magnesia-alumina spinel refractories.This material has excellent refractoriness property,thermal shock resistance,coating adherence,corrosion resistance and higher mechanical strength.It is an excellent material to replace magnesia-chrome brick for sintering zone in cement kiln.
