Fired kaolin clay has a variety of uses, mainly reflected in the following aspects:

I. Manufacturing refractory bricks

Fired kaolin clay is an important raw material for manufacturing high alumina bricks, mullite bricks, insulation bricks and other refractory bricks. Its high alumina content high refractoriness make it able to maintain stability in high temperature environment, without melting or deformation. For example, high alumina bricks are widely used in the lining of high furnaces and kilns in steel, cement and other industries.

II Refractory casting material

Fired kaolin clay can be used to produce refractory casting, which has good high temperature stability and corrosion resistance, and is suitable for high temperature furnace lining such as steel ladle and intermediate ladle.

III. Lightweight refract products

Fired kaolin clay can be used to produce lightweight mullite bricks, mullite lightweight aggregate and other lightweight refractory products. These materials have low density low thermal conductivity and good insulation performance, and are suitable for high temperature insulation.

IV. Mullite raw materials

Fired kaolin clay is a natural raw material for synthes mullite, and its refractoriness can reach above 1700℃. Mullite refractory materials have high melting point, low expansion and good heat shock, and are widely used in high temperature furnace lining and kiln utensils.

V. Precision casting

Fired kaolin clay can be used for precision casting of m sand and core materials, with its high purity and uniform particles, which can ensure the surface quality and dimensional accuracy of castings.

VI. Ceramic fiber and glass fiber

ired kaolin clay can be used to produce ceramic fiber and glass fiber, which have good insulation performance and high temperature stability, and are widely used in high temperature insulation materials and fire materials.

VII. Other applications

Fired kaolin clay can also be used to manufacture refractory cement, refractory paint and other materials, and its chemical stability abrasion resistance make it perform well in a variety of high temperature applications.

In summary, fired kaolin clay has a wide range of applications in the field of refract materials, and its excellent refractoriness, chemical stability and physical properties make it an indispensable raw material in the high temperature industry.
