Embodiment 1
[0022] Embodiment one builds the firing of " white porcelain " rice bowl
[0023] Step 1: Take 10kg of "Jianbai Porcelain" clay that has been vacuum-fired;
[0024] Step 2, making 10 green bodies of the rice bowl with the female die roll forming;
[0025] Step 3, after trimming, buckle it on the cake pad and dry it;
[0026] Step 4, put the green body into the kiln and biscuit once at a low temperature of 900°C;
[0027] Step 5: After polishing the biscuit body, evenly apply a layer of "Jianbai Porcelain" glaze on the front and back sides of the body;
[0028] Step 6: Use a damp sponge to carefully wipe off the glaze layer on the edge of the bowl and the bottom foot;
[0029] Step 7, smoothing the surface of the silicon carbide refractory shed plate coated with alumina paint;
[0030] Step 8, carefully turn the glaze body upside down on the refractory shed, pay attention not to touch the bowls, and leave a proper gap;
[0031] Step 9: According to the firing curve tempera...
Embodiment 2
[0034] In step 12, after cooling, the finished product can be obtained, and the high-quality product rate of the finished product is 90%, and the qualified rate is 100%. The firing of embodiment two high-grade teacups
[0035] Step 1, take 15kg of porcelain clay that has been vacuum-fired;
[0036] Step 2, make 20 green bodies of teacups with female mold roll forming;
[0037] Step 3, after trimming, buckle it on the cake pad and dry it;
[0038] Step 4, put the body into the kiln and biscuit once at a low temperature of 850°C;
[0039] Step five, after polishing the biscuit body, apply a layer of enamel evenly on both sides of the body;
[0040] Step 6, use a damp sponge to carefully wipe off the glaze layer on the edge of the cup and the bottom foot;
[0041] Step 7, smoothing the surface of the silicon carbide refractory shed plate coated with alumina paint;
[0042] Step 8, carefully turn the glaze body upside down on the refractory shed board, pay attention not to to...

Abstract
The invention relates to a method for firing a domestic porcelain, in particular to the method for firing high-grade domestic porcelains, such as bowels and cups. The method comprises the following steps of: 1, drying a finished body, placing the body into a kiln to perform biscuit firing at the low temperature of 800 to 900 DEG C, and polishing the biscuit-fired body to smooth; 2, glazing the biscuit-fired body and removing glaze at the mouth rim and foot of the product; 3, directly placing the product on a refractory slab in a reversing way for primary high-temperature glaze firing; and 4, turning the product over, cleaning and partially glazing the mouth rim of the product, placing the product into the kiln again in an erecting way for secondary high-temperature glaze firing, and cooling the product to obtain the finished product. Compared with the conventional low-temperature biscuit-firing high-temperature glaze-firing method or high-temperature biscuit-firing low-temperature glaze-firing method, the method is convenient to operate, ensures the light weight and high superior quality rate of the fired finished product, and is very applied to the production of various high-grade domestic porcelain products, such as the bowels and the cups.
Description
technical field [0001] The invention relates to a firing method of daily-use porcelain, in particular to a firing method of high-grade daily-use porcelain such as bowls and cups. Background technique [0002] Over the years, in order to solve the deformation problem of daily-use porcelain, a large number of ceramic scientific and technological workers and production enterprises have carried out a large number of experiments and research work, and the whole process of production from ceramic mud formulation, molding, drying to firing is controlled. In addition to being harmonious and beautiful in the design of the device type, it is generally necessary to add a thickened edge to the edge of the mouth of the cup, dish and dish; in terms of firing, the currently commonly used firing methods mainly include low-temperature plain firing There are two forms of high-temperature glaze firing and high-temperature plain firing and low-temperature glaze firing, but both have advantages ...
