[0003] Therefore, the addition and use of clay is abandoned in the prior art, but river sand, industrial waste, etc. are used for processing and preparation. For example, the application number is: 201310238704.8 discloses a kind of autoclaved green brick or blue tile, which is made of river sand or Shale, coal rock, lime or cement are prepared as raw materials, and the blue tiles produced have good mechanical properties and weather resistance. Further enhancements are still needed in terms of stability

Description

technical field [0001] The invention belongs to the technical field of blue tile processing and manufacturing, and in particular relates to a process for firing ancient building blue tiles in a double roasting atmosphere. Background technique [0002] In the traditional craft, the green tile is made of clay, which is blue-gray, giving people a simple and elegant, calm, simple and tranquil beauty. In recent years, it has become one of the products highly recommended by designers. Due to the high firing temperature, it has a certain The degree of porcelainization has the advantages of high flexural strength, wear resistance, acid and alkali resistance, and long life, so it is called porcelain blue tile. The traditional firing process is as follows: after the clay is molded, it is dried in the shade, and then fired in an earthen kiln. It needs to undergo carburizing, color retention and other processes before it can be cooled out of the kiln. The whole process lasts about two w...
