Description of fireclay bricks

 

fireclay bricks is dense shaped refractory material. With high refractoriness and mechanical behavior under high temperature, fireclay bricks is the necessary material of high-temperature services, mainly used for industrial furnaces and kilns and thermal equipment.

 

 

Features of fireclay bricks

Low thermal conductivity       
High refractoriness  
High mechanical strength      
Excellent thermal shock resistance

 

Applications of fireclay bricks

 

fireclay bricks has wide applications, mainly used in metallurgy, construction(cement and glass), petroleum, chemical industry, electric power and machine building.

Q:Why is there cracks in the use of refractory bricks?
Several reasons for the emergence of cracks: (1) temperature difference stress (2) mechanical stress (3) crystal type change stress
Q:The stove which made of refractory bricks and fireclays will produce cracks after being used. How to solve this problem?
The use of low expansion materials will be better. But as for the stove, the appearance of crack is attributed to the selected materials or the environment. And when the temperature is not high, there still seems to be crack, so through expansion joint reservation, not allowing itself to crack
Q:Can thick steel plate be used instead of the furnace inside the refractory brick?
It depends on the temperature. The steel plate is a kind of heat conduction material which hasn't heat insulation, which should be based on the working environment.
Q:Why can't build refractory brick behind the skew block?
Refractory is heat expansion and cold contraction, when it is high temperature, it will squeeze toward the center and the vault will be deformation .
Q:Would you please tell me how to use the simple method to identify shale brick, clay brick?
Shale density is small, weigh in hand, feeling relatively light, clay brick is high density, relatively heavy.
Q:th choose of different refractory bricks in the rotary kiln
According to the characteristics of each belt, magnesium chromium brick. Take the most kiln foe example, the configuration of kiln refractory is not the same, the burning of the product is not the same. there are many kinds of rotary kiln. magnesia bricks are generally used in high temperature zone, anti-stripping alumina brick,silmo brick are used in temperate zone, clay brick is mainly used in low temperature zone. generally inlet and the outlet use corundum mullite, wear-resistant castable, spinel brick,etc. select brick of proper performance, but also take into account the economy
Q:Can someone tell me the refractory brick in the boiler mixed with what material to build the wall, and what proportion?
Go to the refractory factory to buy some refractory clay that has the same texture of refractory bricks, the general boiler use clay refractory mortar.
Q:Mainly use the raw materials inside refractory bricks,
Go to the refractory factory to buy some refractory mortar that has the same texture of refractory bricks, the general boiler use clay refractory mortar.
Q:What are the differences between diatomite brick and ordinary refractory bricks?
The volume density of diatomite brick is 3.9 * 10-6, good compressive strength, belongs to the small outer insulation, spinel brick.
Q:Why should the clay bricks be watered first when they are building masonry walls?
Therefore, in order to facilitate the operation, so that the mortar has a suitable hardening and strength growth environment, to ensure the quality of masonry, bricks must be watered before use wet.
