REFRACTORY BRICK
Refractory bricks refers to the brick whose Al2O3 contains from 30% to 80%, the contains of Al2O3 from 30% to 42% is call clay bricks, the contains of Al2O3 from 45% to 80% is call high alumina bricks.
Typical Parameters
Brief description
Clay brick is refers to the Al2O3 content is 30% ~ 40% aluminum silicate. Clay brick is made of soft clay and 50% and 50% of hard clay grog, ingredients required by certain granularity, after forming, drying, burning under the high temperature of 1300 ~ 1400 ℃.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 600tons and fired at 1450-1470 °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.
