Fire Clay Bricks
Product Information
Fireclay bricks belong to one of the main varieties of aluminum silicate products. It is a refractory product made of clay clinker as aggregate and refractory soft clay as binder with Al2O3 content in 35%~45%.
Model: SK32, SK33, SK34, N-1, low porosity series, special series (special for hot blast stove, special for coke oven, etc.)
Features
1. Excellent resistance in slag abrasion
2. Lower impurity content
3. Good cold crush strength
4. Lower thermal line expansion in high temp
5. Good thermal shock resistance performance
6. Good performance in high temp refractoriness under load

Application
Metallurgical Industry
In the metallurgical industry, clay refractory bricks are mainly used in equipment such as blast furnaces, hot blast furnaces and glass kilns. Clay refractory bricks for blast furnaces can withstand high temperatures and corrosive atmospheres to protect the furnace structure; clay refractory bricks for hot blast furnaces are used for the lining of hot blast furnaces to ensure their normal operation; large clay refractory bricks for glass kilns are used in glass melting furnaces to ensure stability and fire resistance at high temperatures.
Chemical Industry
In the chemical industry, clay refractory bricks are used as insulation layers for equipment such as reactors, cracking furnaces and synthesis furnaces. These equipment work under high temperatures and corrosive atmospheres, and clay refractory bricks can effectively reduce heat loss and improve energy efficiency.
Ceramic Industry
In the ceramic industry, clay refractory bricks are used for the insulation walls and roofs of ceramic firing kilns to maintain the high temperature environment in the kiln and promote the firing of ceramic products. Hard clay and semi-hard clay are used as raw materials for the manufacture of daily-use ceramics, building ceramics and industrial ceramics.
Building Industry
Industry In the building materials industry, clay refractory bricks are used to make cement kilns and glass melting furnaces.
