REFRACTORY BRICK 

Refractory bricks refers to the brick whose Al2O3 contains from *0% to *0%, the contains of Al2O3 from *0% to *2% is call clay bricks, the contains of Al2O3 from *5% to *0% is call high alumina bricks.

Typical Parameters 



Brief description

Clay brick is refers to the Al2O3 content is *0% ~ *0% aluminum silicate. Clay brick is made of soft clay and *0% and *0% of hard clay grog, ingredients required by certain granularity, after forming, drying, burning under the high temperature of ***0 ~ ***0 ℃.Clay brick belongs to the weak acid refractory products, can resist acid slag and the erosion of acid gases, the alkali resistance ability is a bit poor. Clay brick has good thermal shrinkage.

High Alumina Brick selected calcined Bauxite and high quality combined clay as main raw materials. After shaped with brick machine above **0tons and fired at ********0 °C , we can get this product. With high Al2O3 content, the product have good high temperature performance, so it is widely used in all kinds of industrial furnace and high temperature parts to prolong the life of furnace.

Products advantage

Clay Brick

1.Good acid stability

2.Good thermal performance

3.good thermal shrinkage

4.Good resistance to abrasion and corrosion

High Alumina Brick

1. High refractoriness, High-temperature endurable.

2. Good corrosion resistance.

3. Good spalling resistance and wear resistance. 

4. Good thermal shock resistance. 

5. High mechanical strength.

6. High-temperature creep rate is low.

7. Good volume stability at high temperature. 



Typical Application

Clay brick is suitable for secondary parts of coke oven, such as regenerator seal wall, small flue lining brick and regenerator checker brick lining brick, roof, door and rising pipe lining brick, etc.It is one of refractory brick used in blast furnaces, hot blast stove, heating furnace, power boiler, lime kiln, rotary kiln, ceramics.

High alumina brick is mainly used for masonry in blast furnaces, hot air stoves, electric furnace roof, blast furnace and reverberatory furnace, rotary kiln lining. In addition, high alumina brick also widely used for open hearth regenerative checker brick, pouring system with plug head, gate brick, etc.
