In industrial areas, where temperature is usually at significant levels, usual bricks can not be applicable for a rough and long-term usage. Employing them will only cause trouble and affect operational consistency and efficiency. This is where a savvy industrialist opts for high alumina bricks, which come with invaluable properties that make them suitable for high-temperature environments.
Unlike fire clay bricks, high alumina refractory bricks are designed to be utilized in various industrial applications whereas fire clay bricks do not offer prolonged and continuous operational service. This makes high alumina refractory bricks the most important component for industries where severe conditions are frequent. In this blog post, we will explore high alumina bricks and their significance in high-temperature conditions.
A Brief Introduction to High Alumina Bricks
High alumina bricks are the specialized type of refractory bricks produced using various high-purity raw materials, including alumina (Al2O3), silica (SiO2), clay (acts as a binder), and often chemical additives.
During the manufacturing process, all the materials are chosen in precise amounts. However, the alumina content is usually ranging in between 30% to 50% of the whole content. Each material possesses unique features, improving bricks’ overall structure, operational performance, and long life.
The premium-quality materials get carefully crushed, molded, and fired at high-temperatures. After the manufacturing process is done, the quality control unit checks if the bricks are all ready, and meets all the standards of quality and performance. The final output is suitable for harsh industrial applications.
Role of High Alumina Refractory Bricks in Extreme Temperature Settings
The high alumina refractory bricks possess various invaluable characteristics that make them a preferred choice for various industries. Let us discuss the importance of these refractory bricks in high-temperature settings in detail.
1. Kiln Chambers
In various manufacturing industries, the kiln chambers are usually operated in a high-temperature environment. These kiln chambers require bricks with high refractory properties, which of course makes high alumina bricks the best choice. The alumina refractory bricks enable kiln chambers higher thermal stability, resistance against thermal shocks, and mechanical strength, enabling them to give peak performance for a longer period.
2. Furnace Front Equipment
Furnace front equipment such as charging systems, tapping ladles, furnace doors, burners, cooling systems, and others are usually exposed to high-temperatures. To protect them and extend their lifecycle, high alumina refractory bricks are employed. These bricks offer thermal insulation and enduring capability against corrosive substances as well.
3. Furnace Chambers
In various industries furnace chambers are employed for heating and processing materials at controlled temperatures. These furnace chambers also require protection against varying temperature levels. For this reason, high alumina bricks are used in the lining of the furnace chambers, ensuring the safety of the equipment.
4. Electric Furnace Chambers
The high alumina bricks have melting points of 1700°C to 1800°C, making them highly suitable for high-temperature settings, without losing their structural integrity and offering their best performance. This feature of the bricks makes them a priority to be used in electric furnace chambers.
Difference Between High Alumina Bricks & High Alumina Fire Bricks
Normally, people think that high alumina bricks and high alumina fire bricks are the same. Although they are made up of the same material, they serve different purposes. High alumina bricks contain an alumina content of around 50 percent, while high alumina fire bricks contain more than 50 percent of alumina content.
Even though both are crafted to withstand a high-temperature environment, the high alumina fire bricks are specially made for extreme settings where thermal shocks and chemical attacks are beyond high level. Both types of bricks are applicable for various industrial applications. However, when the requirement is for supreme quality bricks, the high alumina fire bricks are required to be manufactured.
To sum up
The high alumina bricks are made to withstand high-temperature environments which are usual in manufacturing and other processing industries, making them the most reliable choice for industrialists. Their unique combination of properties such as chemical endurance, thermal stability, wear resistance, and high durability, is what sets them apart from usual fire bricks.
