Embodiment Construction

[0010] Now in conjunction with accompanying drawing and embodiment the present invention is described in further detail:

[0011] The present invention is achieved in this way, including the molding process of the clay pot body in which the bottom surface 1a of the clay pot is concave spherical, and the high-temperature firing process. Firing, the clay pot body has a certain plasticity at high temperature, and the clay pot body 1 is placed in the male and female molds 2 and 3 with fixed cavity shapes for setting (such as figure 1 Shown), in order to overcome the disordered deformation in the high temperature firing process. In order to further accurately control the external dimensions of the clay pot, a grinding process is set after the setting process, that is, the concave spherical bottom surface 1a is polished by the convex spherical emery wheel 4 .

Abstract

A method for preparing clay-pot, comprising body molding process of the clay-pot and high-temperature sintering process, is special in a molding process after high-temperature sintering process, which means that the clay-pot has plasticity at high-temperature due to the high-temperature sintering and is molded in a male and female die with fixed die cavity shape, so as to overcome disordered distortion in the high-temperature sintering process. The present invention is characterized in easy control of shape size in high-temperature clay-pot sintering process when compared with the prior techniques.

Description

Technical field: [0001] The invention relates to a manufacturing method of a ceramic pot. Background technique: [0002] Existing clay pots need to be calcined at high temperature during manufacture, and ceramics have large shrinkage and deformation during calcination. Therefore, their external dimensions are difficult to control, so that they cannot be well used in electric rice cookers. Invention content: [0003] The object of the present invention is to provide a method for manufacturing a clay pot whose external dimensions are easy to control when the clay pot is fired at high temperature. [0004] The present invention is achieved in this way, including the molding process of the clay pot body and the high-temperature firing process. It has a certain degree of plasticity, and it is placed in a male and female mold with a fixed cavity shape for setting, so as to overcome the disordered deformation in the high-temperature firing process. After adopting the above-ment...
