Embodiment Construction

[0020] The present invention will be further described below in conjunction with embodiment.

[0021] The ceramic product is a ceramic annular product, and the raw material is alumina (aluminum oxide content 92%). The product size outer diameter after firing is 240mm, the inner diameter is 200mm, and the height is 100mm. The kiln loading method of the present invention has obtained good effect.

[0022] Specific steps are as follows:

[0023] (1) Repair the blank of the ceramic product, especially the end face placed on the refractory ball.

[0024] (2) Use an electric kiln to burn, clean up the shed board for the kiln, place it in a suitable position in the kiln, and use alumina ceramic refractory balls with a diameter of 2.5mm (alumina content of more than 99% on the shed board) ) into a ring shape, the inner circle of the ring is required to be smaller than the inner diameter of the product, and the outer diameter of the ring is larger than the product, and it is required...

Abstract

The invention relates to a firing and kiln placing method of a ceramic product, belonging to a technical field for producing the ceramic product and comprising placing half-finished ceramic product on a load bearing board; the invention is characterized by firstly placing refractory balls on the load bearing board and then placing the half-finished ceramic products on the refractory balls. The invention effectively solves the problems of distortion and cracks during the firing process of the ceramic products, and increases the product quality and firing qualified rate; the invention has high production efficiency and low production cost.

Description

technical field [0001] The invention relates to a firing kiln loading method for ceramic products, which belongs to the technical field of ceramic product production. Background technique [0002] At present, the application fields of ceramic products are becoming wider and wider, and the development is rapid. Ceramic products are no longer limited to the scope of daily necessities. Compared with metal materials, ceramic materials have the advantages of wear resistance, high strength, high hardness, acid and alkali resistance, corrosion resistance, low expansion, low creep, etc., and can adapt to the environment and working conditions that metals and polymers cannot bear. So it is widely used in petroleum, chemical industry, coal, electric power, textile, electronics, aviation, aerospace, ceramics, automobile, food, medicine and paper making and other fields. With the continuous expansion of the application field of ceramic products, the demand is also increasing. [0003]...
