Hot isostatic pressing sintering treatment process for accurately grinding ceramic balls
The invention relates to a hot isostatic pressing sintering treatment process for accurately grinding ceramic balls, which is characterized in that during sintering, heating and heat preservation are performed in stages, and in the process, the temperature in a furnace is increased along with the increase of the air pressure in the furnace. And heating-heat preservation is carried out in stages, and the heating rate of each stage is controlled to be gradually reduced, so that when the temperature in the furnace is increased to reach the phase transition temperature of the product, the temperature in the furnace is uniform, and the temperature difference value of different heating areas is always kept in a tiny acceptable range, the consistency of the products in the same furnace is ensured, and the yield is improved.
本发明涉及一种精磨陶瓷球热等静压烧结处理工艺，在烧结时，分阶段进行加热‑保温，在此过程中，炉内温度升高，同时伴随着炉内气压升高。分阶段进行加热‑保温，并控制各阶段加热速率逐渐递减，如此，使得炉内温度升温达到产品相变温度时，炉内温度统一，不同加热区的温度差异值始终保持在微小可接受的范围内，保证了同一炉产品的一致性，提高了成品率。
