Jun porcelain sintering process

Abstract

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.

Description

technical field [0001] The invention belongs to the field of ceramic technical equipment, and in particular relates to a Jun porcelain firing process. Background technique [0002] Jun porcelain originated in the Eastern Han Dynasty. It is one of the five famous kiln porcelains in the Song Dynasty. It is a treasure in the traditional porcelain making process of the Han nationality. The reputation of "he" is so rich that it is not as good as a piece of Jun porcelain. It is a unique national treasure porcelain in Shenhou Town, Yuzhou City, Henan Province. The magical kiln changes of "a thousand colors out of the kiln", the infinitely changing graphics, colors and wonderful charm of lakes and mountains, clouds and mist, humans, animals, flowers, birds, insects and fish, etc., are known as the first of China's "Five Famous Porcelains". It is not easy to make, and 70% of the products will be scrapped during the firing process. Therefore, the waste of raw materials for Jun porcel...

[0002] Jun porcelain originated in the Eastern Han Dynasty. It is one of the five famous kiln porcelains in the Song Dynasty. It is a treasure in the traditional porcelain making process of the Han nationality. The reputation of "he" is so rich that it is not as good as a piece of Jun porcelain. It is a unique national treasure porcelain in Shenhou Town, Yuzhou City, Henan Province. The magical kiln changes of "a thousand colors out of the kiln", the infinitely changing graphics, colors and wonderful charm of lakes and mountains, clouds and mist, humans, animals, flowers, birds, insects and fish, etc., are known as the first of China's "Five Famous Porcelains". It is not easy to make, and 70% of the products will be scrapped during the firing process. Therefore, the waste of raw materials for Jun porcelain is huge, the cost is too high, and the qualified rate of finished products is very low. In order to overcome this problem, a Jun porcelain firing craft is necessary
