Free falling body sintering process of ceramic part

NI QINGHE / WENG GONGYU / YE TING / YE WANQING

The invention relates to a sintering process of a ceramic part, in particular to a free falling body sintering process of the ceramic part. According to the technical scheme, the free falling body sintering process of the ceramic part is characterized by comprising the steps that firstly, a blank is formed, the formed blank is subjected to early-stage sintering, after the blank is formed through early-stage sintering, the formed blank enters a forming combustion channel in a free falling body mode, the temperature in the forming combustion channel is 1000 DEG C or above, and the temperature in the forming combustion channel is 30 DEG C or above; the shaped blank passes through the forming combustion channel to form a ceramic part finished product, high-temperature liquid is arranged below the combustion channel, and the ceramic part finished product falling from the combustion channel falls into the high-temperature liquid to be rapidly cooled. The scheme is adopted. The invention overcomes the problems in the prior art, and provides a novel free falling body sintering process for the ceramic part, which is low in cost and high in speed.

本实发明涉及一种陶瓷件的烧结工艺，特别是指陶瓷件的自由落体烧结工艺。本发明采用如下技术方案：一种陶瓷件的自由落体烧结工艺，其特征在于:先把胚料成型，成型后的胚料进行前期烧制，前期烧制到胚料定型后，然后定型胚料以自由落体式的方式进入成型燃烧通道，成型燃烧通道内的温度在1000度以上，定型胚料经过成型燃烧通道后形成陶瓷件成品，在燃烧通道的下放设置有高温液体，从燃烧通道中掉落的陶瓷件成品落入高温液体迅速降温。通过采用上述方案。本发明克服现有技术存在的问题，提供一种成本低，速度快的新型的陶瓷件的自由落体烧结工艺。
