Refractory bricks play a pivotal role in thermal containment environments. Their inherent safety and performance enable them to function effectively under extreme temperature conditions. Unlike ordinary bricks, refractory bricks exhibit exceptional resistance to cracking or performance degradation under high temperatures and mechanical stresses. Consequently, they are indispensable components in high-temperature applications. Kerui Refractory mainly provides the following 9+ types.
What Are Refractory Bricks?
Refractory bricks are specialized construction materials designed to withstand extreme heat and harsh environments. They are typically composed of a blend of refractory materials, mineral substances, and other raw ingredients. They are processed through various manufacturing techniques. These bricks are characterized by their exceptional refractoriness, chemical corrosion resistance, and ability to endure thermal shock.
What is the Refractory Brick Made of?
Refractory bricks China are composed of a blend of raw materials, each contributing specific properties to the final product. These materials can be broadly categorized into the following groups: Alumina (Al2O3), Magnesia (MgO), Silica (SiO2), Chrome Ore (Cr2O3), Zircon (ZrSiO4), Magnesite Dolomite (MgCO3•CaCO3), clay, other raw materials. These refractory materials have different physical and chemical properties, such as refractoriness, flexural strength, load softening temperature, thermal conductivity, thermal shock resistance, and so on. Therefore, they are used in the production of various refractory bricks.
What Is the Manufacturing Process of Refractory Bricks?
Different usage scenarios have different performance requirements for refractory bricks. Therefore, in order to meet the needs of various scenarios, Kerui Refractory will produce different refractory bricks according to the following processes.
- Pressing: Manufacturing equipment presses the raw materials into refractory bricks.
- Sintering: After the raw materials are pressed into bricks, the bricks are sintered and formed at high temperatures.
- Electric melting: The raw materials are melted in an electric arc furnace. The they are poured into molds, and cooled to form refractory bricks.
