- Q: What's the reason of cracks in refractory bricks?
- The relative density is high, and high temperature heat treatment and increase the strength of qualitative brick, for 10 days, then only the shorter time for heating and drying and dehydrating, you can smash a brick if it's a long time! There will be a stress loose phenomenon making bricks now, the internal density of these crack bricks are not the same, in addition to the effective drying, dehydrating and heating treatment, the time distance is small, basic bricks and finished bricks adopt line production, when drying, the water is also evaporated at the same time, the central density should be high ! The reason is very simple, the greater extrusion force the brick bears in the molding, the closer to the edge, the smaller density is, the better to keep forming, the shorter residence time, the higher the rate of finished product is, which belongs to the natural drying, this phenomenon is more obvious
- Q: What is refractory brick? What is refractory clay? ?
- refractory brick----is refractory material with a certain shape and size. According to the preparation process, bricks can be classified into burnt bricks, unburned brick, electric melting brick (fused cast brick) and the refractory insulating bricks; according to the shape and size, bricks can be classified into standard brick, ordinary brick and specific brick and etc. High-temperatured building material and structural material that can be used to build furnaces and various thermal equipments, and can endure various physical and chemical changes and mechanical effects at high temperature. For example, refractory clay brick, high alumina brick, cilica brick and magnesia brick and etc.. Fireclay -- usually refers to a kind of soil clay used for fire the stove and the furnace hearth in folk 1, characteristics and usages: Clay refractory brick is a kind of weak acid refractory material, its thermal stability is good, suitable for hot blast stove, various boiler lining, and flue, smoke room, etc.. 2, product specifications: Standard form, general profile, special shaped and special shaped brick. Physical and chemical properties of clay refractory bricks. The upper limit ---- about 1500 degrees under normal pressure
- Q: What is the meaning of special shaped refractory brick material n-2b?
- In fact, there are many kinds of refractory bricks, titanium, high alumina refractory brick, after drying. The mineral composition of the clay brick is mainly kaolinite (Al2O3·2SiO2·2H2O) and 6% ~ 7% impurities (K, etc.). Clay refractory bricks are iron oxide sintered by 50% soft clay and 50% hard clay clinker ingredients according to a certain granularity requirements under the high temperature of 1300 ~ 1400 degrees), perlite
- Q: How to classify light refractory bricks?
- Continuous casting use silicious insulation board, silica insulating refractory brick, ceramsite lightweight refractory concrete building block and so on. 0g/ clay lightweight heat insulating brick NGO.4-1.5g/, high aluminum lightweight heat insulating brickLGO.4-0.4-1.7G/, resistance furnace Diatomite brick 0; cm3; cm3; cm3, aluminum oxide insulating refractory products
- Q: What are the differences between sintered bricks and refractory bricks?
- Easily weathered. There is no obvious difference in the usage between fired pavingbricks and refractory bricks; sintered bricks are generally used for residential road and landscape engineering, they do not fade; refractory bricks are used for all kinds of kiln constructions in plant: It is not anti-freeze (when the temperature is below the zero degree, the brick will easily "blister" in the saturated state), the reasons are high compressive strength and high temperature zone' heat insulation and so on. Fired pavingbrick is a powerful vacuum extrusion type. Fire suppression road brick is high temperature furnace brick, which is not suitable to be used as road brick. Its characteristics are: Wear resistance and freeze-thaw resistance (the anti freeze-thaw cycle of brick is more than 50 times in saturated state), non weathering, sidewalks, short service life. Sintered brick belongs to the building material, refractory brick belongs to the industrial kiln material, which is easy to moss
- Q: Can red bricks be burned in tunnel kiln which used to burn refractory brick?
- It can be used to burn the red brick, as long as the temperature is almost the same
- Q: is there any requirement for radioactive materials in refractory materials.
- they all do not cause radiological hazards to the environment, so no requirements! analyze rom the element , magnesia. Do not know if it is useful, but material used by refractory materials, firstly any chemical elements are radioactive, human beings can not close, then, such as silicon dioxide: If it is radioactive. analyze from use, such as bauxite, does not have the use value
- Q: What are the properties of clay bricks?
- Clay brick is very important. It can make clay brick not only with high refractoriness, but also can be used in many high temperature thermal equipment. The brick brick has better resistance to hot and cold, and the water cooling can reach 10~25 times at 850 centigrade. Clay brick can resist weak acid slag corrosion, the resistance to alkaline slag is slightly worse, increasing the content of Al2O3, can improve the ability of alkali resistance slag.
- Q: What is the proportion of lightweight fireclay bricks?
- It is a lightweight refractory product containing aluminium 30%-46%. It is made of clay clinker or light clinker as the main raw material. It is usually produced by combustible material. It can also form porous structure by chemical or foam method.
- Q: what should press on the heat preserving cotton above the suspended ceiling refractory brick ?
- you can also put Z shaped steel on the purline, put heat preserving cotton on the roof boarding, it is easy to oprate.
