In the ceramic industry, refractory mud is widely used, mainly in the following aspects:

I. Masonry of kiln lining

Refractory mud is used to build the lining of ceramic kiln, including kiln wall, kiln roof, flue and other parts. It can ensure that the gaps between refractory bricks are tightly filled, thus improving the integrity and sealing of the kiln and preventing the leakage of heat and flame.

II. Repair of kiln lining

During the use of ceramic kiln, the lining may be damaged due to high temperature, mechanical impact or chemical erosion. Refractory mud can be used to quickly repair these damaged parts and restore the integrity and service life of the kiln.

III. Making Sagger and Cushion Cake

Sagger is an important tool to protect the green body during ceramic firing. Refractory mud can be used to make saggers to ensure that they will not be deformed or broken at high temperature, thus protecting ceramic bodies. In addition, refractory mud is also used to make cushion cakes and washers, which can prevent ceramic bodies from sticking during firing.

IV. Protective coating on kiln surface

Refractory mud can be applied to the surface of kiln lining by daubing or spraying to form a protective coating. This coating can not only insulate heat, but also prevent the furnace lining from chemical erosion.

V. Sealing of high-temperature equipment

Refractory mud is also used to seal the doors, covers and other parts of the ceramic kiln to prevent the leakage of high-temperature gas and ensure the normal operation of the kiln.

VI. Special purpose refractory mud

In some special cases, special additives (such as chromium oxide) can be added to the refractory mud to improve its corrosion resistance and high temperature resistance, so as to meet the higher requirements of the use environment in the ceramic industry.

In a word, refractory mud is an indispensable material in ceramic industry, which not only improves the service life and operation efficiency of kiln, but also ensures the quality and safety of ceramic production.
