Product Details

Product Display of Refractory Block Alkali Resistant Brick

High-strength 
Refractory Block Alkali Resistant
Bricks are produced from
low-aluminum refractory clay as the main raw material.
They have a high-temperature ceramic crystalline phase
structure, which closes the open pore channels of the
product, so as to achieve the purpose of resisting
chemical corrosion and preventing the penetration and
deposition of alkaline gases and impurity components.
It is widely used in cement kiln preheating
system.

High-strength 
Refractory Block Alkali Resistant Bricks are
often used in the cement industry, and the transition zone
of rotary kilns is made by adding additives to improve
compressive strength. It overcomes the shortcomings of
ordinary high-alumina bricks, such as poor thermal shock
resistance, low corrosion resistance to cement clinker, and
low softness of phosphoric acid
bricks.

Application of Refractory Block Alkali Resistant Bricks

Cement
kiln alkali-resistant bricks are divided into four
types: ordinary type, high-strength type, vault type
and thermal insulation type. The preheater and
decomposition furnace are located at the end of the
entire hot air flow.
High-strength 
Refractory Block Alkali Resistant Bricks are
mainly used in the preheater of cement kiln.
High-strength alkali-resistant bricks are mainly used
in the calciner area of cement kilns. High-strength
alkali-resistant bricks are mainly used in the
tertiary air duct of cement kilns.
