Material for preparing ceramic riser tube, ceramic riser tube and preparation method of ceramic riser tube
The invention provides a material for preparing a ceramic riser tube, the ceramic riser tube and a preparation method of the ceramic riser tube. The material of the ceramic riser tube is prepared from, by weight, 45-55 parts of corundum, 35-45 parts of mullite and 5-15 parts of zirconite. The ceramic riser tube prepared from the material has the characteristics of high temperature resistance, pressure resistance, erosion resistance, excellent shock resistance and the like, thermal shock can be generated on the riser tube in the stages of vacuumizing, mold filling, pressurization and pressure maintaining in the anti-gravity casting process of the high-temperature alloy, and mullite and zirconite have good thermal shock resistance, so it can be guaranteed that the riser tube is not damaged in the whole experiment process.
本发明提供了一种用于制备陶瓷升液管的材料、陶瓷升液管及其制备方法，陶瓷升液管的材料由以下重量份数的原料组成：刚玉45～55份，莫来石35～45份，锆英石5～15份。本发明由上述材料制备的陶瓷升液管，具有耐高温、耐压、抗侵蚀和抗震性优良等特点，在高温合金反重力铸造过程的抽真空、充型、增压和保压阶段会对升液管产生热震，采用莫来石和锆英石具有良好的抗热震性能，能够保证升液管在整个实验过程中不发生破损。
