Volume-stable high-temperature bedplate and manufacturing method thereof
The invention discloses a volume-stable high-temperature bedplate, belonging to the field of refractory kiln furniture preparation. According to the invention, sintered corundum and fused mullite particles are used as aggregates, and an aluminum titanate composite phase material is introduced into a matrix, and sintering at a high temperature is carried out to obtain the bedplate; and the preparedbedplate can meet the requirements for high-temperature strength and good thermal shock resistance on the bedplate in use and is obviously improved in volume stability, and the size change of the bedplate in an advancing direction is less than or equal to 0.5% after long-time circulation in a use environment.
一种体积稳定型高温台板，属于耐火窑具制备领域，以烧结刚玉、电熔莫来石颗粒为骨料，基质中引入钛酸铝复合相材料经高温烧制而成，制得的台板既能保证台板使用的高温强度及热震性好的要求，另能明显提高台板的体积稳定性，经在使用环境下长时间循环后测试，推进方向的尺寸变化≤0.5%。
