Sintering method based on sintering temperature curve of high-porosity honeycomb ceramic
The invention discloses a firing method based on a firing temperature curve of high-porosity honeycomb ceramics. The firing method comprises the following steps: heating from room temperature to 250 DEG C at a heating rate of 9 DEG C/h; raising the temperature from 250 DEG C to 400 DEG C at the temperature raising rate of 4 DEG C/h; raising the temperature from 400 DEG C to 800 DEG C at a heating rate of 8 DEG C/h; raising the temperature from 800 DEG C to 1250 DEG C at the temperature raising rate of 8 DEG C/h; raising the temperature from 1250 DEG C to 1420 DEG C at a heating rate of 3 DEG C/h; keeping at 1420 DEG C for 8 hours; reducing the temperature from 1420 DEG C to 1200 DEG C at a cooling rate of 40 DEG C/h; according to the method, the temperature is reduced to the room temperature from 1200 DEG C at the cooling rate of 13 DEG C/h, coke is smoothly discharged according to a set temperature curve, cracking caused by severe combustion or uncompleted degreasing is avoided, finally, the whole firing curve is determined according to the performance requirement of the product, and the performance technical parameters and the high product percent of pass of the fired product are achieved.
本发明公开了一种基于高气孔率蜂窝陶瓷烧成温度曲线的烧成方法，以9℃/小时的升温速率从室温升至250℃；以4℃/小时的升温速率从250℃升至400℃；以8℃/小时的升温速率从400℃升至800℃；以8℃/小时的升温速率从800℃升至1250℃；以3℃/小时的升温速率从1250℃升至1420℃；1420℃保持8小时；以40℃/小时的降温速率从1420℃降至1200℃；以13℃/小时的降温速率从1200℃降至室温，按设定温度曲线平缓排焦，避免剧烈燃烧或脱脂未完成造成开裂，最终根据产品的性能要求确定整个烧成曲线，实现烧成后产品的性能技术参数和高的产品合格率。
