High Alumina Brick
High Alumina Brick
High alumina bricks are refractory bricks with an alumina content of 50% or more. They are produced by a specific process with strict quality control. These bricks are used for industrial applications due to their high temperature performance, excellent corrosion resistance, and low iron content. As a result, they are highly regarded in the refractory industry.
The properties of high alumina bricks are derived from their composition and sizing. High alumina bricks are produced from alumina that has been refined through the Bayer process. Some high alumina bricks contain up to 85% alumina. This brick is a high-performance building material that is also attractive and highly rigid.
High alumina bricks can be custom-made in size and shape to match the requirements of a specific application. They can also be used in blast furnaces. For example, high alumina refractory bricks can be used in the furnace mouth. These bricks can be easily shaped to meet the specifications of any furnace mouth.
High alumina bricks have high compressive strength and thermal shock resistance. They help reduce the heat capacity of the furnace walls and increase the efficiency of furnaces. The Rongsheng refractory bricks company produces a variety of specifications and models. The company offers high quality refractory bricks at competitive prices.
Another important characteristic of high alumina bricks is their fire resistance. They can withstand temperatures up to 15,000 °C. They have one of the lowest thermal conductivities of all refractory materials. This property makes them ideal for metallurgy and glassmaking. Because of their high temperature resistance and durability, these bricks have many applications.
The RUL (refractory unit load) of high alumina bricks varies with the percentage of Al2O3. Fireclay bricks have lower RUL capacity and are more likely to shrink when placed under high temperature. They can only be used in subordinate parts of a furnace. They also need to be protected from chemical reactions.
Fireclay bricks are made of hydrated aluminum silicates. The material is one of the least expensive firebricks available and has a high magnesium content. Magnesite, on the other hand, is best suited for metallurgical applications and has a high resistance to iron slag and lime. Silica, on the other hand, is a mineral composed of 93% SiO2. Its mechanical strength makes it a desirable material for glassmaking and steelworking.
