However, in the molding of fired carbon, the purpose is to obtain fired carbon that does not contain air bubbles, is dense, and has few impurities.
本発明の焼成品の成型方法を例示図面により説明する。The method for molding a fired product of the present invention will be explained with reference to illustrative drawings.

Fix tightly. Attach a suitable packing (8) to the inner periphery of the lower part of the enclosure (7). Inside the box (7) is the pulp (9), and the filter +111 via the check valve (II).
, the vacuum tank 1121 and the vacuum pump Q31 are communicated with each other. (141 is true destructible pulp.

When the lower plate (2) is further raised, the mold (3) is strongly compressed and molded by the upper and lower discs.The vacuum pulp α gradient in the shell (7) is opened and destroyed, and the molded product is taken out.

ができるのである。In the method for molding the fired product of the present invention, the raw material powder is 300%
Since it is heated to around 0.99°C or higher, most of the organic matter and impurities are gasified, and this gas is extracted by a vacuum pump, and almost all of the volatile matter and air in the raw material powder are also extracted. Therefore, according to the method of the present invention, it is possible to obtain a baked product that is bubble-free and has a high quality when used for color and sliding friction! Even if it is overheated, cracks or partial bulges due to expansion of internal bubbles or expansion of volatile components can be prevented, and a product with a high Pv value can be obtained.
