Product Description:

High alumina fireclay Brick  


High alumina fireclay Brick for Heating Furnace is a kind of insulation material adopting organic matter as ignition loss substance in order to increase the porosity of refractory, which has such advantages as high porosity, small volume density, good insulation effect, high mechanical intensity, small thermal conductivity and long service life. For various industrial kilns & furnaces, it is a kind of essential refractory for energy saving and temperature preservation.

This series of High Alumina fireclay Brick for Heating Furnace are made of selected high alumina bauxite, kaolin caly, hollow microsphere as the mian material.By shaping at high pressure and sintering at high temperature. 

Fireclay brick is  shaped refractory product.It is made from flint clay clinker and binder , Through high heat sintering. The Al2O3 content range from 28% to 48%.The refractoriness range from 1580°C to 1750°C(SK-30.SK-32.SK-34.SK-35).

Produce Processing 

Crushing

In this stage massive raw materials which have been stored, are ground and classified into proper sizes, making them easier to shape.

Mixing

The prescribed size of ground raw material is weighed and mixed into a designated amount of water and forming agent.

Shaping

The mixture is then poured into a mold to form shapes, and the pressure is high.

Drying 

In this stage water is removed from the shaped bricks. This helps preventing the bricks from deforming or cracking which may result due to the rapid evaporation

Firing 

This is the most crucial process in refractory manufacturing. The modeled bricks are fired at high temperature to complete their thermochemical reaction so that they do not deform.

Inspection 

The bricks' physical and chemical properties are inspected very carefully by rigid quality management procedures.

Packing shipment

We guarantee efficient delivery every time.

Q:The difference between clay bricks and clay bricks?
Sintering bricks do not have clay bricks, so sintering bricks are made of stone. Clay brick is clay cooking, two yo, qualitative difference, but the appearance and color almost, but the quality is very different, life expectancy is also a great gap.
Q:Do slag bricks have clay bricks strong enough?
Clay bricks you mean should be red bricks burned out of the fire.
Q:Whether the fire bricks are needed to be poured before construction?
It should be properly watered, according to its water absorption rate: Need to soak and dry in the shade. There is no need to do like the ordinary red brick
Q:Why is the brick instead of solid clay brick
Shale has the characteristics of high temperature resistant, is fire gangwa, pottery, porcelain power the best materials, especially shale burning system with shale brick is a new type of environmentally friendly building materials, has become the main building material to substitute for clay brick, high economic and social benefits, the market prospect is broad, is the best raw material for production of high hollow brick wall the quality of the.
Q:Can common cement mortar be used to build the lining of chimney refractory brick?
No. You have used fire bricks, which shows there is a certain temperature inside, you'd better use refractory cement
Q:Are clay bricks radioactive?
Basically, any substance has radiation, because natural conditions contain a lot of radioactive particles, and even the body itself has reflective particles, such as carbon 14, but the dose is safe.
Q:How to make refractory bricks? ? ?
Solution of the production of refractory brick raw materials
Q:What are the materials for building blocks and what are the specifications?
Material: clay brick, shale, coal gangue brick, fly ash brick, lime sand brick, concrete brick etc..
Q:What is sintered non clay brick?
According to the different production process of bricks into sintered brick and non sintered brick. Sintered brick in China has more than two thousand years of history, is still a very wide range of wall materials. Many kinds of brick, according to the raw materials used for clay brick, shale, coal gangue brick, fly ash brick, lime sand bricks and slag brick;
Q:what kind of refractory brick is suitable for 1300 degrees converter?
The furnace cap tapping shaft part should use MgO-C brick with high slag resistance and thermal shock resistance, the steel side can be slightly thin, bottom carbon content may be appropriate less.
