refractory

Refractory bricks, also called shaped refractory materials, have high strength and wide applications and are easy to construct. They have been widely used in a variety of industrial furnaces.

(1) Common fire clay bricks are generally used in the refractory masonry of furnaces and kilns. in the linings, walls, bottoms and flues, they are used below 1250℃. When used in the combustion chamber, they can be used above 1400℃.

(2) High alumina bricks are generally used in the parts of furnaces exposed to high temperature, severe erosion and high load, burner bricks and some parts that have special requirements. They are allowed to be used at 1300-1650℃.

(3) Lightweight fireclay bricks can be used in the lining of furnaces to resist high temperature molten slags and corrosive gases. They can be used at 1150-1400℃.

(4) Lightweight alumina bricks can be used the low-temperature linings below 1350℃ and the parts that are not exposed to high temperature molten substances and erosion. They can be in direct contact with the flame.

(5) Common corundum brick can be used in the hot face of linings in heavy oil gasifiers, important parts of saline wastewater incinerators and radiant burners. It is generally used below 1600-1670℃.

(6) Silicon carbide bricks have high thermal conductivity, good thermal stability and high strength. They can resist the reductive atmosphere. They can be used in the lings that are required to have good wear resistance, good thermal stability, good thermal conductivity and reductive atmosphere resistance. they can be used below 1400-1600℃.
