Coke CDQ Refractory Brick

 

Benefits of Refractory Bricks For Coke Dry Quenching

The linear expansion rate is low. The linear expansion rate within 1000℃ is less than 0.16%, and the high-temperature volume is stable. During service, the structure of the kiln will not be stabilized due to thermal expansion;

 

The product has high volume stability. Under normal circumstances, there will be no cracking or deformation. And the repair process does not need to stop the furnace, can be repaired directly under high-temperature conditions;

 

Excellent thermal shock stability. During the service process, the product is placed at a high temperature of 1600 ℃, and it will not break or flake;

 

The softening temperature under load is up to 1650℃ and the compressive strength is over 30MPa;

 

High purity. The mass fraction of silica is greater than 99%. Strong anti-erosion ability, safe and reliable for long-term use.

 

Manufacturing Process of Refractory Bricks For Coke Dry Quenching

 

Digging

First comes digging when raw materials such as silica, clay, alumina, and magnesia are extracted from quarries or mines. These are chosen depending on the properties of the final refractory product created.

01

Weathering

The extracted raw materials are exposed to weathering. This can help reduce moisture content and improve the durability. As a result it becomes easy to form acid proof bricks later.

02

Tempering

The raw materials are mixed with water to form a plastic clay-like mixture. This mixture is then tempered, which involves kneading as well as rolling to achieve uniform consistency and eliminate any kind of air pockets.

03

Moulding

Molds help shape any mixture into a desired brick form. The process of molding can be done via different methods like extrusion, pressing, or casting.

04

Burning

The molded bricks are fired in kilns at very high temperatures starting from around 1300°C to 1800°C (2372°F to 3272°F). It depends on the type of brick as well as its application. This firing process results in a dense and durable refractory structure.

05

FAQ

 

 

Q: Which type of refractory bricks are used in Coke oven wall?

A: Coke ovens are made of numerous refractories for various component materials. The main materials used are silica bricks constituting the coke oven wall.

Q: What is the life of refractory bricks?

A: In high-intensity settings like kilns or furnaces, the lifespan of refractory bricks depends on operational demands. These bricks may need replacement every 1 to 5 years depending on factors like heat exposure, chemical interactions, and mechanical wear.

Q: Are refractory bricks acidic or basic?

A: At high temperatures, acidic refractories may also react with limes and basic oxides. Silica refractories are refractories containing more than 93% silicon oxide (SiO2). They are acidic, have high resistance to thermal shock, flux and slag resistance, and high spalling resistance.

Q: Do refractory bricks hold heat?

A: Dense refractory bricks have a high thermal mass which is sometimes a useful property in that they will retain heat eg in a pizza oven after the fire has been taken out.

Q: What is the melting point of refractory bricks?

A: The refractory bricks have a very high melting point and are often made to withstand temperatures in excess of 1000°C (1832°F). This allows them to be used in applications where exposure to heat is long lasting. Even under severe thermal stress, they do not easily crack or deform, hence keeping their shapes intact.
