High Alumina Refractory Brick Thermal Shock Resistance For Blast Furnace
Description
High Alumina Refractory Brick for Blast Furnace is a type of refractory brick made from high-quality raw materials, such as bauxite, corundum, and high-purity spinel. These bricks are designed to withstand the harsh conditions inside a blast furnace, including high temperatures, abrasion, and chemical corrosion.
The key properties of High Alumina Refractory Brick for Blast Furnace include high refractoriness, excellent thermal shock resistance, good mechanical strength, and high resistance to chemical attack. These properties make these bricks ideal for use in the hot blast stove, blast furnace hearth, and other areas of the blast furnace.
The manufacturing process of High Alumina Refractory Brick for Blast Furnace involves mixing high-purity raw materials, such as bauxite and corundum, with a binder and forming the mixture into bricks under high pressure. The bricks are then fired at high temperatures to create a dense, hard structure.
