Kerui Corundum Mullite Brick: A High-Performance Refractory Material

Kerui corundum mullite brick is a type of refractory brick that is made from a combination of corundum and mullite. Corundum is a mineral form of aluminum oxide (Al2O3), and mullite is a mineral that is composed of aluminum oxide and silica (SiO2). Kerui corundum mullite bricks are known for their high refractoriness, excellent thermal shock resistance, and good chemical stability. They are widely used in a variety of industrial applications, including glass melting furnaces, cement kilns, and petrochemical reactors.

Properties of Kerui Corundum Mullite Brick

1. High refractoriness: Kerui corundum mullite brick has a high refractoriness of up to 1750°C (3182°F). This means that they can withstand very high temperatures without melting or losing their structural integrity.

2. Excellent thermal shock resistance: Kerui corundum mullite bricks have excellent thermal shock resistance, which means that they can withstand rapid changes in temperature without cracking or spalling. This makes them well-suited for use in applications where the temperature fluctuates frequently.

3. Good chemical stability: Kerui corundum mullite bricks are resistant to attack by most chemicals, including acids, alkalis, and salts. This makes them a good choice for use in applications where the bricks will be exposed to harsh chemical environments.

4. High strength: Kerui corundum mullite bricks have high compressive strength and modulus of rupture. This means that they can withstand heavy loads without breaking.

5. Low thermal conductivity: Kerui corundum mullite bricks have low thermal conductivity, which means that they are good insulators. This helps to keep the heat inside the kiln or furnace, which can improve efficiency and reduce energy costs.

Benefits of Using Kerui Corundum Mullite Brick

There are many benefits to using Kerui corundum mullite brick in industrial applications. Some of the most important benefits include:

1. Improved furnace efficiency: Kerui corundum mullite bricks can help to improve furnace efficiency by reducing heat loss. This can save money on energy costs and help to reduce the furnace’s environmental impact.

2. Longer furnace life: Kerui corundum mullite bricks can help to extend the life of the furnace by protecting it from damage caused by heat and chemicals.

3. Reduced maintenance costs: Kerui corundum mullite bricks are durable and long-lasting, which can help to reduce maintenance costs.

4. Improved product quality: Kerui corundum mullite bricks can help to improve the quality of the products being produced by providing a more stable and uniform heating environment.

Applications of Kerui Corundum Mullite Brick

Kerui corundum mullite bricks are used in a wide variety of industrial applications, including:

1. Glass melting furnaces: Kerui corundum mullite bricks are commonly used in the construction of glass melting furnaces. They are used for the walls, floors, and roofs of the furnaces, as well as for the construction of burners and other components.

2. Cement kilns: Kerui corundum mullite bricks are also used in the construction of cement kilns. They are used for the walls, floors, and roofs of the kilns, as well as for the construction of clinker coolers and other components.

3. Petrochemical reactors: Kerui corundum mullite bricks are used in the construction of petrochemical reactors. They are used for the walls, floors, and roofs of the reactors, as well as for the construction of catalysts and other components.

4. Other applications: Kerui corundum mullite bricks are also used in a variety of other applications, including incinerators, waste heat boilers, and metallurgical furnaces.

How to Install Kerui Corundum Mullite Brick

Kerui corundum mullite bricks are relatively easy to install. The following steps are a general guide:

1. Prepare the surface. The surface that the bricks will be installed on should be clean, dry, and level.

2. Apply a mortar. A thin layer of mortar should be applied to the back of each brick.

3. Position the bricks. The bricks should be positioned carefully to ensure that they are level and plumb.

4. Tap the bricks into place. A mallet can be used to tap the bricks into place.

5. Allow the mortar to dry. The mortar should be allowed to dry completely before the furnace or kiln is put into operation.
