Buy Refractory Bricks

Aluminum-silicon refractory bricks consist of Al2O3 and SiO2. At the same time, they are a series of fire products because of their exceptional refractory properties. These bricks exhibit a refractory temperature typically exceeding 1600℃ (2912℉). The category of aluminum-silicon fire bricks has a variety of options, including high-alumina bricks, clay bricks, mullite bricks, corundum bricks, AZS bricks and more. Each of these bricks offers unique characteristics and advantages to suit diverse industrial requirements.

Magnesia refractory bricks mainly consist of magnesia raw material. They are alkaline composite refractory products. What’s more, magnesia refractory bricks’ chemical composition is primarily MgO and CaO, with the MgO content in the bricks typically exceeding 60%. Their common variations include magnesia bricks, magnesia aluminum bricks, magnesia calcium bricks, and so on. Meanwhile, as high-grade refractory bricks, they offer a wide range of applications.

When it comes to silica bricks, it is talking about refractory bricks with a SiO2 content of more than 90%. They are a type of refractory brick primarily composed of high-quality quartz or silica sand. However, it is important to note that silica refractory bricks are not suitable for thermal equipment operating below 600℃ (1112℉) or subject to substantial temperature fluctuations. As a result, when you select refractory materials for your specific thermal equipment, you should consider their limitations in such conditions.

The dimension of standard bricks is 230*114*65mm. Standard refractory bricks are commonly referred to as traditional or conventional refractory bricks. They represent a universal standard in the industry. Because these bricks adhere to well-established norms, specifications and quality standards to ensure reliable performance. Therefore, these bricks can meet the needs of various applications.

Straight refractory bricks are also known as rectangular or square refractory bricks. They all possess a distinctive shape characterized by their rectangular or square dimensions. You can use them for lining straight walls and floors, which will offer a seamless and precise fit. With their uniform shape, straight refractory bricks ensure efficient installation and provide structural integrity to the lined surfaces.

Wedge refractory bricks are narrower at one end and wider at the other. As a result, industries can apply them for constructing arched structures, such as kiln roofs or furnace crowns. Besides, You can assemble them into arches or domes, which can provide structural stability to the fire-resistant lining. Therefore, the correct assembly method of wedge refractory bricks is very important when using them.

Anchor refractory bricks can anchor or hold the refractory lining in place to maintain structural stability. This refractory bricks are a key component of refractory linings as they ensure safe and efficient high-temperature industrial processes. Thus, the choice of anchoring system and bricks depends on factors such as equipment type, operating temperature and thermal expansion considerations.

For the above common refractory brick shapes, you can also purchase customized refractory bricks that suit special needs from Kerui Refractory. These special bricks fit specific installations, such as curved refractory bricks, large refractory bricks or other complex structures. Therefore, Kerui can produce these bricks according to the drawings you provide. Besides, they can reduce your cost.

The first step is to obtain the necessary raw materials, including alumina, mullite, silica, and so on. These materials are carefully selected based on their purity and quality to ensure the desired properties of the refractory brick.

The raw materials are mixed together in precise proportions to achieve the desired composition. The mixture of the refractory bricks is then molded into bricks through a molding process such as extrusion or pressing.

After forming, the refractory bricks are dried to remove moisture and ensure dimensional stability. The bricks are gradually heated to evaporate the moisture by controlling the temperature and airflow conditions.

Dry refractory bricks are fired in a high-temperature kiln. The firing process involves heating the bricks to a specific temperature. This step helps to sinter and fuse the raw materials, which results in a strong and durable structure.

Heating and cooling of refractory bricks refer to the gradual cooling of the kiln after the brick’s heating and firing process is complete. The cooled refractory bricks are then inspected for quality control to ensure they meet the standards.

The final step includes packaging refractory bricks for shipping and distribution to customers or end users. The bricks are generally carefully packaged to prevent damage during handling and transportation.
