Multifunctional ceramic firing kiln and manufacturing method of porcelain thereof

Abstract

The invention discloses a multifunctional ceramic firing kiln and a manufacturing method of porcelain of the multifunctional ceramic firing kiln. The multifunctional ceramic firing kiln can fire pottery and the porcelain, the firing effect of the pottery and the porcelain is good, implementation is easy, and the firing effect is good. The multifunctional ceramic firing kiln comprises a kiln body. The kiln body is provided with an electric heating device and a fuel gas heating device at the same time. The electric heating device comprises an electric heating body, and the fuel gas heating device comprises a gas mixing device. The method includes the steps that in the heating firing process, when the temperature of a kiln chamber rises to a certain numerical value, a blank in the kiln chamber and / or kiln gas in the kiln chamber are / is fully oxidized, the kiln chamber is heated through furnace gas, certain carbon monoxide is generated in the kiln chamber through fuel gas combustion, reduction flames are generated, and the porcelain blank in the kiln chamber continues being heated and fired.

Description

technical field [0001] The invention relates to firing of a ceramic product. In particular, it relates to a multifunctional ceramic firing kiln and a method for making porcelain. Background technique [0002] Ceramic products generally include pottery products and porcelain products, and pottery and porcelain products are essentially two types of ceramic products with different properties. In actual production, in the existing ceramic product processing and firing process, both pottery and porcelain are fired using the same function and structure type gas kiln firing device. However, because pottery and porcelain not only have certain differences in raw materials and certain processing techniques, but also have certain differences in the nature, performance and function of their products. This determines that the two should be different in the firing process, otherwise, the effect and texture of the fired porcelain products will be lacking. For example, when using the sam...

Problems solved by technology

The type of kiln that can complete this process is a gas kiln, but the defects of this kiln are: First, the heat utilization rate is low: because the gas kiln uses convective heat transfer, about 40% of the heat is discharged through the chimney with the convection of hot gas outside the kiln; the second is that it is difficult to automate the operation of gas, and the technical difficulty of manual operation is extremely high. Even the masters who have been engaged in this work for decades sometimes miss the operation, and the labor intensity is relatively high.
