The invention relates to a jun porcelain
sintering process. The jun porcelain
sintering process comprises the steps of bisque firing,
glazing and
glaze firing. The bisque firing step comprises the following sub-steps that 1,
green body inspection is performed: finished green bodies to be put in a
kiln is inspected according to the standard, and the qualified can be put in the
kiln after inspection; 2,
kiln charging is performed: the qualified finished green bodies are loaded on a supported kiln car shed plate according to different categories in a classified mode; 3, access to the kin is performed: a charged kiln car is slowly pushed into the kiln at a
constant speed, and a kiln door is closed; 4, firing is performed: the temperature in the kiln gradually rises from normal temperature to 900 DEG C within 4 hours, and then fire is ceased; 5, cooling is performed: the temperature in the kiln is naturally reduced to 100 DEG C, then the kiln door is opened to avoid the phenomenon that the
green body suddenly cracks due to too quick temperature reduction, the kiln car is pulled out at the moment, and the fired
green body is taken. The jun porcelain
sintering process has the advantages of being reasonable in technological process, low in production cost and high in finished product pass percent.
