- Good thermal stability
- Large elastic modulus
- High density
What is Basic Refractory Brick?
Basic refractory brick is a kind of refractory material with good alkali resistance, fire resistance and corrosion resistance. It can resist the corrosion of various strong concentrations of lye, and can be used in many alkaline process equipment. It is made of alkaline refractory clay, admixture and water, and sintered at high temperature. It has good alkali resistance, fire resistance and corrosion resistance.
Magnesia brick is a brick-shaped building material fired from magnesium slag. It has good thermal resistance and insulation performance, which can effectively reduce the energy consumption of buildings and save energy.
Magnesia-aluminum spinel brick is a kind of brick body with good fire resistance. It is mainly made of pure magnesium aluminate after high temperature sintering, and has good high temperature resistance and corrosion resistance.
Magnesia alumina spinel bricks are mainly made of magnesium alumina spinel, high-carbon powder slag, alumina powder slag and other raw materials. It has the advantages of high thermal stability and high refractoriness
Magnesia chrome refractory brick is a kind of refractory material processed by special process. Its raw material is magnesia alumina, which is sintered at high temperature. Refractory temperature can reach 1600℃.
Magnesia calcium brick is a new building material made of magnesia and calcium sand and sintered. It has good fire resistance, alkali resistance and acid and alkali resistance, and can resist flame erosion and temperature changes.
Application of Basic Refractory Brick
-
Alkaline refractory bricks are mainly used for the protection of the hearth and hearth of the electric arc furnace to prevent the molten metal from corroding the furnace wall, reduce the heat loss of the electric arc furnace，reduce energy consumption
-
GlassIn glass furnaces, basic refractory bricks are the most commonly used refractory materials. They have good thermal shock resistance, can resist corrosion and high temperature, and protect the safe operation of glass furnaces.
-
Steel LadleAlkaline bricks have good heat resistance and strong impact resistance, which can ensure that the structure of the ladle will not be damaged when the ladle is used in a high temperature environment and when heavy materials are loaded.
-
Lime KilnThe main purpose of alkaline bricks is to be used as the lining of lime kiln, so that the temperature and corrosion environment of lime melting in the kiln can be controlled, and the efficiency of lime melting in the kiln can be improved.
-
CementAlkaline bricks have excellent acid and alkali resistance, heat resistance, wear resistance and durability. It can be used in the sintering furnace of cement kiln, such as sintering chamber and sintering smoke exhaust chamber.
