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:How to test the various components of the refractory brick?
If you want to know the chemical compound components, you can do the analysis of meteorological chromatography, and then testing, if you just want to detect contents of elements, you can do a XRF, but you should smash, grind and homogenize the refractory bricks. The specific operation process is not convenient to describe in detail, that is, X ray diffraction, through X ray fluorescence analysis, you can know that the elements and contents contained in it, if you want to understand its internal structure, you can also do a XRD
Q:How are shale porous bricks and clay porous bricks distinguished?
Weathering resistance is better than clay brickDue to differences in clay shale and its performance, the national standard requires shale weathering properties than clay bricks.
Q:The service life of the refractory brick of the intermediate frequency electric furnace, how long is the replacement period.
There is no standard. As long as the induction coil can be fixed and furnace lining can be built, the service life will be different. Replace it if it's broken, and there is no problem to take it apart. Buy a backup. And the textures of refractory brick are not the same in different places.
Q:Where are clay bricks or cement bricks?
Cement brick is the use of fly ash, cinder, coal gangue, slag, chemical residue or natural sand, sea mud etc. (more than one or several kinds of raw materials) as the main raw material, made of cement coagulant, a kind of new wall materials by high temperature calcination made called cement brick.
Q:The shape and size of general used refractory brick
According to the national standard, the outline dimension of mechanism red brick is: length is 240mm, width is 115mm and thickness is 53mm. That is: 240mm * 115mm * 53mm. The shape and size of the ordinary refractory bricks are: Length is 230mm, width is 114mm and thickness is 65mm, that is: 230mm * 114mm * 65mm. The shape and size of special refractory bricks are: 345mm*328mm*97mm.
Q:What raw materials can be added to fireclay brick to respond to the urgent cold and urgent heat?
The effect of adding andalusite is better
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:1200 degrees inside the furnace, lay a layer of refractory brick, what is the temperature outside?
except refractory brick, refractories include refractory concrete (refractory cement+aggregate), fire-resistant insulating layer (refractory cement+vermiculite powder or refractory cement + diatomaceous earth) and so on.
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:What is the relationship between the firing process and the manufacturing technique of fireclay bricks?
