Self-lubricating self-repairing unfired blind plate for tundish and preparation method of self-lubricating self-repairing unfired blind plate
The invention discloses a self-lubricating self-repairing unfired blind plate for a tundish and a preparation method of the self-lubricating self-repairing unfired blind plate. Belongs to the field of shaped refractory materials and comprises the following raw material components: sintered tabular corundum aggregate, sintered tabular corundum fine powder, alpha-Al2O3 micro powder, metal silicon powder, metal aluminum powder, nano carbon black, Ti3AlC2 fine powder and phenolic resin. The preparation method comprises the following steps: premixing the sintered tabular corundum fine powder, the alpha-Al2O3 micro powder, the metal silicon powder, the metal aluminum powder, the nano carbon black and the Ti3AlC2 fine powder in a high-speed stirrer, then stirring the sintered tabular corundum aggregate in a low-speed stirrer, adding the liquid phenolic resin, adding the premixed powder, continuously stirring, and carrying out uniform mixing to obtain a finished product. Carrying out pressure forming, curing and heat treatment on the mixed raw materials in a mold with a fixed size by using a hydraulic machine; according to the invention, Ti3AlC2 with a layered self-repairing characteristic is added, so that the blind plate has good self-lubricating and self-repairing characteristics at a high temperature, has high oxidation resistance and thermal shock resistance, and has a higher use effect and a longer service life compared with a traditional corundum castable blind plate.
本发明公开了一种中间包用自润滑自修复免烧盲板及其制备方法；属于定型耐火材料领域，其原料成分如下：烧结板状刚玉骨料、烧结板状刚玉细粉、α‑Al2O3微粉、金属硅粉、金属铝粉、纳米炭黑、Ti3AlC2细粉及酚醛树脂；其制备方法：将烧结板状刚玉细粉、α‑Al2O3微粉、金属硅粉、金属铝粉、纳米炭黑、Ti3AlC2细粉在高速搅拌机中预混，然后将烧结板状刚玉骨料在低速搅拌机中搅拌加入液态酚醛树脂，加入预混好的粉体继续搅拌，将混好的原料用液压机在固定尺寸模具中压力成型，固化及热处理即可；本发明在组成中添加了具有层状自修复特性的Ti3AlC2，其在高温下具有良好的自润滑、自修复特性，具有高的抗氧化、抗热震性能，相比于传统刚玉浇注料质盲板具有更高的使用效果和使用寿命。
