Sliding plate brick and preparation method thereof
The invention provides a sliding plate brick and a preparation method thereof, and belongs to the technical field of refractory materials, the sliding plate brick is specifically prepared from a base material composed of tabular corundum, fused alumina zirconia, zirconium oxide, silicon carbide, aluminum powder and modified graphite, reinforced fibers and a modified epoxy resin binder, the materials are mixed, the mixed materials are subjected to mold forming, heat treatment and sintering, a sliding plate brick precursor is obtained, and the sliding plate brick precursor is sequentially subjected to oil immersion carbonization and finish machining treatment to obtain the sliding plate brick. By controlling the content of each component and preparation process conditions, the sliding plate brick with relatively high compactness, excellent anti-scouring performance, excellent anti-erosion performance, excellent thermal shock stability and excellent wear resistance can be obtained, and the defects of the conventional sliding plate brick made of the aluminum-zirconium-carbon material are overcome.
本发明提供了一种滑板砖及其制备方法，属于耐火材料技术领域，具体包括：由板状刚玉、锆刚玉、氧化锆、碳化硅、铝粉、改性石墨组成的基材，增强纤维，以及改性环氧树脂结合剂，经物料混合，将混合后的物料经模具成型、热处理、烧结，得到滑板砖前体，滑板砖前体依次进行油浸碳化、精加工处理得到滑板砖，通过控制各组分的含量、制备工艺条件，可获得具有较高的致密程度、优异的抗冲刷性能、抗侵蚀性能、热震稳定性能和耐磨性能的滑板砖，弥补了目前铝锆碳材质滑板砖的缺陷。
