Embodiment 1

[0028] Non-carburized porcelain blue tiles, according to the weight percentage, the raw materials are composed of 52% bauxite, 23% purple sandstone, 10% clay and 15% gas furnace cinder. The firing process is as follows:

[0029] Step 1, take bauxite, purple sandstone, clay and gas furnace cinder and pulverize and ball-mill them to 20 mesh respectively, and weigh each material according to the above ratio, and set aside;

[0030] Step 2, dry-mixing the material weighed in step 1 and adding 18% of its total weight of water, then stirring evenly to obtain a blank, and then molding the blank to make a green body for subsequent use;

[0031] Step 3, drying the green body made in step 2 at 100°C for 7 hours, and set aside;

[0032] Step 4, send the green body dried in step 3 into the tunnel kiln and roast it with an oxidizing flame. The roasting process is as follows:

[0033] 1) Heating process

[0034] In the tunnel kiln, the firing temperature of the green body is raised to 900...

Abstract

A porcelain grey tile without carburization and a sintering method thereof. Bauxite, purple sand, clay, and gas stove coal cinder are mixed, added with water to prepare a green body, and then the porcelain grey tile without carburization is sintered under a certain temperature condition. According to the invention, a mixture of multiple materials is used instead of pure clay for sintering, which saves clay resources; the green body does not crack when a lot of water is lost within a short period, which greatly shortens the drying time of the green body; during high temperature sintering, carbon particles are generated in raw coal reactions of generator gas and gas stove coal cinder, and colorize the inner and outer sides of the green body, which omits the colorization and color preservation processes in the prior art, shortens the process flow, increases the sintering efficiency, and saves energy.

Description

technical field [0001] The invention relates to the firing field of building materials, in particular to a non-carburized porcelain blue tile and a firing method thereof. Background technique [0002] Blue tiles are made of clay and are blue-gray in color, giving people a sense of elegance, calmness, simplicity, and tranquility. In recent years, they have become one of the products highly recommended by designers. Due to the high firing temperature, they have a certain degree of porcelain , has the advantages of high flexural strength, wear resistance, acid and alkali resistance, and long life, so it is called porcelain blue tile. The firing of blue tiles in the prior art adopts the following process: the clay is molded and dried in the shade, and then fired in an earthen kiln, it needs to go through carburizing, color retention and other processes before it can be cooled out of the kiln. The whole process is about It lasts for about two weeks, which makes the production ef...
