Heavy industries work in environments that are subjected to harsh temperatures and mechanical stresses. Traditional construction materials might be unable to survive these harsh conditions, which is the reason why high alumina fire bricks find extensive use in furnaces and kilns where very high temperatures are encountered. BM Enterprises is one of those companies that provide high alumina bricks and other types of refractory bricks.
Actual technical properties can vary by grade and manufacturer specification. Product selection should be based on the specific operating conditions.
What Are High Alumina Fire Bricks?
High alumina refractory bricks are top-quality refractories made with a high percentage of alumina (Al₂O₃). The materials used to manufacture such bricks provide very high resistance to heat, wear, chemicals, and thermal shock. Based on grades, the high alumina refractory bricks can be chosen depending on the amount of alumina required in an application. BM Enterprises produces high alumina refractory bricks comprising roughly 40, 60%, 70%, and 80% Al₂O₃, based on applications and availability.Key Features of High Alumina Bricks
High Alumina Refractory Bricks are ideal for use in harsh industrial conditions because they have both thermal and mechanical properties. High alumina for high-temperature use- Very good refractoriness and thermal shock resistance
- High resistance to abrasion and mechanical stresses
- Chemical resistance to slag and corrosion in appropriate applications
- Low thermal expansion during operation
- High dimensional stability
- Used in furnaces, kilns, boilers, and similar equipment
- Can be manufactured in standard and application-specific shapes and dimensions
Applications in Heavy Industries
Firebricks are an important element in various industrial heating processes. The high alumina type is especially suitable in places where regular refractory bricks cannot fulfill the requirements. Some of the applications for this type of firebrick are: Typical applications include:- Industrial furnace and heating furnace
- Steel and metal production furnace
- Cement plant and rotary kiln
- Boiler and thermal system
- Foundry and melting furnace
- Heat treating furnace
- Lime and mineral process plant
- Incinerator
- Burning zone and high-temperature zone
- Industrial chimney and heat-intensive zone
