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:What is the refractory brick of the electric furnace?
there is no problem if it can be dismantled. And refractory brick material of every place is not the same, life is not the same. Buy some for backup , and change it once it is broken, there is no standard, the lining can be hit, as long as the induction coil can be fixed
Q:What to do if refractory bricks saltpeter when they are used outdoor
Efflorescence is usually dialysised from brickwork joints, dealing with the gap is ok These white substaince inside the pan tile: Cement efflorescence efflorescence is wow cake section from light leather intestinal common disease inumiya Hua building surface, according to their different causes and manifestations, there is pan cream, white, whitening, cream, on the walls and decorative surface erosion and other names, is the change of soluble saline alkali soil, adobe, brick, cement, mortar, concrete, masonry, ceramic tile, paint and other building materials with temperature, humidity and other external environment, in a water absorption, water transfer, water evaporation process with physical and chemical changes of the original building material damage disease phenomenon, erosion degree also has the very big difference there is a common, get damp, foaming, powder, drum, hollowing, cracking, spalling, mildew and crystallization phenomenon. Cement efflorescence may have some relationship with the quality of the cement, sand, water, air, temperature, humidity, it is a common fault in building. Use cement to do the pebble shape, it also prones to the above problems: A layer of white stuff on the surface. Terms of settlement: Scrape the dust in brickwork joint, pointing again. Use special pointing agents, more resistant to corrosion, not easy to efflorescence.
Q:Do refractory bricks resist corrosion and sulfur?
The refractory brick just plays the role of resisting high temperature and insulating heat.
Q:How to choose refractory brick
The design of size and selection of refractory brick shape mainly depend on the design of industrial furnace lining . The size and shape of refractory bricks must meet the needs of furnace refractory brick masonry, it both ensures the convenience of building and usability of thermal equipment. (such as sealing, insulation, brick grade and service life etc.). When the furnace design company designs furnace lining of refractory bricks, first it should design the size of refractory bricks or choose standard size refractory bricks, sometimes this work is done by a furnace company, sometimes it is done by furnace construction company or furnace maintenance company directly. The refractory bricks that has a certain size designed by the furnace design companies or construction companies, in addition that it should satisfy furnace operation and operation life, it also considers whether it is convenient for refractory factories to produce refractory bricks, besides, it should take into account that whether the pass rate on main production process and finished product rate is high when bricks are moulded, installed and fired. Refractory it is convenient to operate, and is convenient for refractory factory producing, the selection of shape of refractory bricks and the design of and the brick molding, and on this basis, found the relationship between the size of wedge brick, brick level and service life etc.), some even combine refractories with furnace, but each has its inherent regularity. The foreign refractory attaches great importance to building furnace, the height of furnace should be integer times of the thickness of brick (including brickwork joint)
Q:what is consequence of high load and soft low of high alumina refractory brick ?
softening, if not up to the design requirements, may cause vicious incident like the collapse of the stove in use. the full name is softening temperature under a fixed load, as the name suggests, it is the softening temperature after adding the load.
Q:Do refractory bricks insulate heat?
Refractory bricks have a certain ability of heat insulation, but its thermal insulation is far less than that of glass fiber and wool.
Q:Why limit sintering brick first and develop new wall material?
The common brick used in the sintering brick will be used to borrow soil from the farmland, which will lead to the degradation and abandonment of the land. The clay belongs to the cultivated land, and protects the cultivated land in order to protect the precious land resources.
Q:What kind of refractory brick is suitable for clinker production line of 2,500 tons?
Silicon carbide composite brick, series of refractory casting material, etc.. In addition to choose above refractories, suggested to put the thermal insulative alkali-resistant clay bricks or ordinary clay brick on the front and back kilneyes, use high strength alkali-resistant clay bricks or alkali resistant castables for arching the roof , insulating brick vault series: use direct- bonded magnesia-chrome brick in burning zone and high alumina brick in decomposing belt. if it is cement kiln then use skilled production line of 2000 tons, combined with silicon carbide brick
Q:How much refractory material is required for 1 million tons of coke oven
This depends on the number of specific cubic, different factory designs different boiler, we need volume to caculate.
Q:Does circulating fluidized bed boiler's furnace wall use refractory to have thermal insulation?
Now all use castable refractory, the outer layer is generally pouring refractory castable, the inside layer is a heat insulation castable refractory.
