Q & A

How do refractory materials perform under reducing atmospheres?

Refractory materials generally perform well under reducing atmospheres due to their ability to withstand high temperatures and chemical reactions. These materials have a high resistance to corrosion and oxidation, which makes them suitable for applications in industries such as steelmaking, ceramics, and glass manufacturing.

How are high-alumina refractory bricks obtained and processed for refractory production?

High-alumina refractory bricks are obtained and processed for refractory production through a series of steps. The process typically involves sourcing high-quality raw materials, such as bauxite or alumina, which are then crushed and ground to a fine powder. This powder is mixed with various additives, binders, and water to form a moldable clay-like mixture. The mixture is then shaped into brick forms through various methods such as extrusion, pressing, or casting. These green bricks are then dried to remove any remaining moisture. Next, the dried bricks undergo a firing process in a kiln at extremely high temperatures, typically above 1500°C. This firing process, known as sintering, helps to further strengthen the bricks by causing a chemical reaction that bonds the particles together, resulting in a dense and highly durable structure. After sintering, the bricks are cooled down and undergo quality control checks to ensure they meet the required specifications for refractory applications. The final high-alumina refractory bricks are then ready for use in various industries, such as steel, cement, glass, and petrochemical, where they exhibit excellent thermal resistance and durability.

What are the refractory raw materials used in lining acid storage tanks?

The refractory raw materials commonly used in lining acid storage tanks are acid-resistant bricks or tiles, which are made from materials such as silica, alumina, and various types of clay. These materials have excellent resistance to acid corrosion and can withstand the harsh chemical environment inside the tanks. Additionally, acid-resistant mortars and coatings may also be used to enhance the protection and longevity of the tank lining.

How does the addition of calcium aluminate improve the properties of refractories?

The addition of calcium aluminate improves the properties of refractories in several ways. Firstly, it increases the refractoriness, or the ability to withstand high temperatures, of the refractory material. Calcium aluminate has a high melting point and excellent heat resistance, allowing refractories to maintain their structural integrity even at extreme temperatures. Additionally, calcium aluminate enhances the strength and stability of refractories. It forms durable compounds that improve the bonding between particles, resulting in higher mechanical strength and reduced risk of cracking or spalling under thermal stress. Furthermore, the addition of calcium aluminate can enhance the corrosion resistance of refractories. It forms a protective layer on the surface of the refractory material, which helps prevent chemical reactions with aggressive substances or molten metals, thereby extending the lifespan of refractory linings. Overall, the inclusion of calcium aluminate in refractories is crucial for achieving superior thermal stability, strength, and corrosion resistance, making them suitable for various high-temperature applications like furnaces, kilns, and reactors.
