Refractory brick lining is widely used, and it is mainly used in the lining of various kilns. The main function of Kerui refractory bricks is to protect industrial kilns from adverse factors such as high temperature and chemical corrosion. Thus, this can achieve the purpose of extending the service life of the kiln.
3 Major Categories of Refractory Brick Lining
Acidic Refractory Bricks
- Features: Acidic refractory bricks are mainly made of silicon-containing minerals (such as silica, quartz, etc.). Therefore, it has good acid resistance. Its melting point is also high and can withstand corrosion from acidic substances.
- Application: Commonly used in industrial furnaces in acidic environments. Such as glass kilns, ceramic kilns, petroleum refining units, and fertilizer production equipment.
- Common types: silica refractory brick, fire clay brick, acid refractory brick.
Basic Refractory Bricks
- Features: The main components of alkaline refractory bricks are magnesium oxide (MgO) and chromium oxide (Cr2O3). It has excellent alkali resistance. It is suitable for high temperature and alkaline environments.
- Application: Widely used in ladle, blast furnaces and converters. The ladle lining bricks are especially suitable for environments that need to come into contact with molten iron and slag.
- Common types: magnesia brick, magnesia carbon brick, magnesia chrome brick.
Neutral Refractory Bricks
- Features: Neutral refractory brick liner are mainly composed of bauxite (Al2O3) and mullite (3Al2O3·2SiO2). They have strong tolerance to both acidic and alkaline environments.
- Application: Suitable for environments that require both acid and alkali resistance. For example, chemical reactors, gas generators and petrochemical furnaces.
- Common types: high alumina brick, mullite brick, corundum brick.
