The invention discloses a production process of a high-
hardness ceramic tile, and belongs to the technical field of
ceramic tile production. The production process comprises the following steps: taking materials, selecting sufficient pug, sand, a blank body and a blank body reinforcing agent, taking the sand material and the blank body, putting the sand material and the blank body into a
ball mill, and carrying out ball milling. By properly increasing the content of aluminum
oxide in the
ceramic tile formula and adding a proper amount of blank reinforcing agent, the deformation degree of the prepared ceramic tile can be effectively reduced, the high-temperature non-deformability and
drying strength of the material are improved, the
thermal expansion coefficient of the blank is reduced, the expansion coefficients of the later material and
glaze are better matched, the
glaze quality is ensured, and
glaze forming rate is improved. Meanwhile, a
slurry sieving process and a multi-time
iron removal process are set, coarse particles and some impurities which are not finely ground during ball milling can be effectively removed through sieving, the situation that black spots, molten holes, impurities and other defects are formed on the surface of the ceramic tile can be effectively avoided through multi-time
iron removal, meanwhile, the whiteness of the ceramic tile is guaranteed, the quality of the ceramic tile is improved, and the application effect of the method is improved.
