Description for Fire Brick
Refractory brick for sale, also called firebrick and refractory firebrick, is made of fireclay or refractory ceramic materials through molding and firing in the high temperature. Its Refractoriness is 1580~1770 ℃. Refractory bricks have the similar shape with common building bricks. Refractory brick is mainly used in the high-temperature equipments for resisting high temperature corrosion, mechanical erosion and all kinds of chemical erosion. There are many types of refractory bricks according to different chemical component and mineral composition. Refractory brick’s quality and properties depend on its chemical component. Different refractory bricks are available for different position in furnace or kiln. So it is veary important to choose the right firebricks for the right area application in furnace, kiln or oven.

Properties of Fire Brick
- Chemical composition: determine firebrick’s quality and characteristic.
- Bulk Density: greater bulk density, the density is good and, strength is high and thermal conductivity is greater at the situation of one unit bulk quantity.
- Apparent Porosity: Strictly control the apparent porosity.
- Refractoriness Under Load: it is also called initial refractoriness under load, whose reference is marked the high temperature resistance.
- Thermal Shock Resistance: Capacity for resistance to the rapid variation of temperature without break.
- Compressive Strength: Capacity for bearing the maximum pressure in the common temperature.
- Flexural Strength: Capacity for bearing cutting pressure.
- Linear Changing Rate: It is also called reheating linear change, which means at the same change of temperature the bulk expanse.
- Resistance to Wear and Thermal Conductivity
- Shock Resistance: The greater shock resistance, the longer service life.
- Resistance to Slag: Capacity for resistance to slag erosion without break.

Application of Fire Brick
Fire brick for sale can be used as high temperature building materials and structure materials for building kiln and all kinds of heating equipment bearing all kinds of physical chemistry change and mechanical action under the high temperature. Such as fireclay brick, high alumina brick, silica brick, magnesite brick and etc.
- High alumina brick: with over 75% Al2O3 content and high refractoriness. Have good resistance to acid and alkali erosion. It is suitable used for position of firing zone in cement kiln.
- Spinel brick: It is widely used for transitional zone of cement kiln with good resistance to shock and good reduction-resistant.
- Silicon carbide brick: It is suitable used for cooling zone and outlet of kiln with high temperature resistance, low thermal expansivity, good resistance to wear and good thermal shock resistance.
- Silica mullite brick: Its raw materials are bauxite and SiC, being pressed and sintered. It is suitable used for transitional zone with good thermal shock resistance, high strength and good resistance to wear.
- Fireclay brick: It is a kind of weak acidic refractory. It has good heat stability and is suitable used for lings of hot blast stove.
