Environment-friendly low-carbon magnesia carbon brick and preparation method thereof
The invention discloses an environment-friendly low-carbon magnesia carbon brick and a preparation method thereof, and relates to the technical field of low-carbon magnesia carbon bricks. Ingredients of the environment-friendly low-carbon magnesia carbon brick comprise a magnesium base material, a carbon base material, a filling base material and an auxiliary base material, and the content ratio of the magnesium base material to the carbon base material to the filling base material to the auxiliary base material is 1.5:1:0.5:0.2. According to the environment-friendly low-carbon magnesia carbon brick and the preparation method thereof, graphite is replaced by environment-friendly coal pitch, the compression strength of a magnesia carbon brick finished product is effectively improved, fibrous AIN and nano magnesium aluminate spinel can be generated in the magnesia carbon brick due to the addition of the environment-friendly coal pitch, and the total carbon amount of a traditional magnesia carbon brick is effectively reduced due to the addition of the nano carbon and the modified graphite. The nano carbon can reduce the apparent porosity of the magnesia carbon brick, increase the volume density and improve the strength, erosion resistance, thermal stability and the like of the magnesia carbon brick, the modified graphite can effectively improve the slag resistance of the magnesia carbon brick, the quality of the magnesia carbon brick is effectively guaranteed on the premise of low carbon and environmental protection, and the performance of the magnesia carbon brick is greatly improved.
本发明公开了一种环保的低碳镁碳砖及其制备方法，涉及低碳镁碳砖技术领域，其配料含有镁基材、碳基材、填和基材和辅助基材，其中镁基材、碳基材、填和基材和辅助基材之间的含量比为1.5:1:0.5：0.2。该环保的低碳镁碳砖及其制备方法，以环保煤沥青取代石墨，有效提高了镁碳砖成品的耐压强度，且环保煤沥青的加入，使得镁碳砖中能够产生纤维状AIN和纳米镁铝尖晶石，纳米碳和改性石墨的加入，有效降低了传统镁碳砖的总碳量，其中，纳米碳能够降低镁碳砖的显气孔率，增大体积密度，能够提高镁碳砖的强度、耐侵蚀性和热稳定性等，改性石墨能够有效提高镁碳砖的抗渣性能，在低碳环保的前提下，有效保证了镁碳砖的质量，并对镁碳砖的性能进行了大幅度提高。
