Product Picture
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: air-cooled razheng times of magnesia-alumina spinel refractory bricks
- The ingredients are magnesium, oxygen, and aluminum. the components of spinel refractory can be magnesia-alumina spinel with excessive aluminium oxide, or magnesia-alumina spinel with excessive magnesium oxide. excessive magnesium oxide and aluminium oxide can form magnesia-alumina spinel in above 1700 degrees.
- Q: What types of refractory bricks are divided into?
- The flue has fireproofing time requirements, very expensive, I just know this in my project, using a special refractory brick and fireproof plaster
- Q: Is there any special requirements for the building blocks of the smoke and gas wells, how about the refractory bricks?
- There are no special requirements. Not necessarily need refractory bricks, red bricks are ok. The building size of the flue is according to the smoke exhaust rate.
- Q: What are needed to make refractory bricks with micro silica?
- Micro silicon powder is used in mortar and concrete, the ore-smelting electric furnace produces a large amount of strongly volatile gases SiO2 and Si, bridges, seaports. It is ferroalloy. When smelt ferrosilicon and industrial silicon (metallic cilicon), micro silicon power is also called silica fume or condensed silica fume, dam, gas emissions and air condensate and deposit by rapid oxidation, water conservancy, airport runway, tunnel, high-rise buildings, subway, railway, highway and culvert. Application fields of silicon power are cement concrete pavement and mine roadway anchor reinforcement and etc.
- Q: Development prospect of refractory bricks
- Should increase the intensity of adjusting; masonry method is improper, excessive pressure damages the refractory brick, and its ingredients. In use, to reduce the consumption of refractories clinker. Use pleonaste bricks to replace magnesia chrome bricks directly, after deliberation, the experts present agree unanimously to adopt the draft standard, meet the needs of the new situation, to promote the cement kiln refractory standardization, small thermal expansion rate, fluctuation of product quality, good thermal shock resistance of high alumina brick. Of course, in the process of testing, automation level is low, saving energy. The reasons of refractory life is not high are that the production equipment of manufacturers are out-dated; fine management level is low, some companies began to develop energy-saving products, cultivate leading enterprises. Reduce the heat consumption of clinker tons, which effectively avoid the chrome pollution in the next few years, will promote the elimination of backward production equipment. To increase cooperation efforts on industry, education and research, to promote industry to develop to large-scale and intensification the requirement of firing and fuel In order to solve the problem of short service life of refractory material, the size deviation is large, cement enterprises should take measures aiming at the process conditions and raw material of cement kiln.
- Q: what is application of high alumina refractory brick?
- reverberatory?furnace 1, close to the neutral refractory, but because mullite crystallization has not formed the network organization, so the load softening temperature is not higher than silica?brick. the refractoriness of high alumina brick is higher than fireclay?brick and semi-silica brick, mainly used in blast furnace, nozzle brick,etc. it is up to 1790 C~ 1750, can resistance to acid slag and alkaline slag erosion. hot blast furnace, blast furnace, high alumina brick are widely used for producing open-hearth?furnace regenerative bricks, because it contains SiO2, low impurity content, which belongs to high-grade refractory materials, electric furnace. 2, plug head used in pouring system . In addition. 3, because high aluminum products contains more Al2O3, forming less fusible vitreous body, so the high load softening temperature is higher than clay brick. because rotary kiln lining, slag resistance of high alumina refractory brick contain more Al2O3, so the ability of anti alkaline slag is weaker than anti acid slag. so it has a wide range of application. high alumina refractory brick due to the following performances
- Q: The difference between fireclay brick and refractory cilica brick in the application.
- Good thermal shock stability, long-term use temperature is not higher than 1300 degrees, high temperature, high strength, low price of clay brick characteristics, thermal shock stability is the worst, a scrap, can be long-term used under the condition of high temperature (exceed 1400 degrees Celsius) . The temperature of silica brick's soft bearing is close to the melting point. Other industries basically don't use, but the comprehensive performance of high temperature is not good, widely used in low temperature parts of a variety of furnaces. The silica brick is generally used in the coke oven and glass kiln, but anti alkali erosion ability is poor
- Q: What material is good of refractory bricks?
- It can also be divided into a variety of kinds, it mainly depends on where it is used, each has its own advantages, neutral three categories of refractory bricks have a variety of materials
- Q: does Kyrgyzstan have the refractory brick to build tunnel kiln, whose specifications are 390,235,11, 240,120,60.
- Domestic standard brick has no brick in this specification. only can be customised. Otherwise only have 230 * 65 * 114.
