Low-expansion-rate thermal-shock-resistant erosion-resistant high-strength castable
The invention discloses a low-expansion-rate, thermal-shock-resistant, erosion-resistant and high-strength castable. The castable is prepared from the following raw materials in percentage by weight:0.01 to 28 percent of fused quartz particles with the particle size of 3.1 to 5mm, 20 to 35 percent of fused quartz particles with the particle size of 1.1 to 3mm, 10 to 20 percent of fused quartz particles with the particle size of 0.01 to 1mm, 10 to 15 percent of 200-mesh silicon carbide powder, 1 to 3 percent of 320-mesh sepiolite powder, 3 to 5 percent of yttrium-stabilized zirconium oxide, 3to 8 percent of silicon micropowder, 1 to 3 percent of metallic silicon powder, 4 to 8 percent of active alumina micropowder, 3 to 5 percent of beryllium oxide, 8 to 12 percent of silicon sol, and 0.01-0.2 percent of sodium hexametaphosphate. According to the invention, fused quartz is used as aggregate with addition of silicon carbide powder, silicon micropowder, metal silicon powder, activated aluminum oxide micropowder, silica sol, sepiolite powder, yttria-stabilized zirconia and beryllium oxide to prepare the castable, so that the volume density of the manufactured push plate is 1.95 g/cm< 3 >, the volume density of the push plate is obviously reduced, and the thermal shock stability of the push plate is higher.
本发明公开了一种低膨胀率抗热震耐侵蚀高强浇注料，所述浇注料由以下重量百分比的原料制备：3.1~5mm的熔融石英颗粒0.01~28%、1.1~3mm的熔融石英颗粒20~35%、0.01~1mm的熔融石英颗粒10~20%、200目的碳化硅粉10~15%、320目的海泡石粉料1~3%、钇稳定氧化锆3~5%，硅微粉3~8%、金属硅粉1~3%、活性氧化铝微粉4~8%、氧化铍3~5%、硅溶胶8~12%、六偏磷酸钠0.01~0.2%。本发明通过采用熔融石英做骨料，同时添加碳化硅粉、硅微粉、金属硅粉、活性氧化铝微粉、硅溶胶、海泡石粉料、钇稳定氧化锆、氧化铍做结合剂制成浇注料，其制作成的推板的体积密度为1.95g/cm，明显降低了推板的体积密度，并且其热震稳定性更高。
