- 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: The brick and ordinary clay brick which is expensive
- Of course expensive materials sintered clay brick, sintered clay brick fired common clay, shale and shale and coal gangue as raw materials by high temperature firing,
- 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: 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: 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: What are the differences between fireclay brick and high alumina refractory brick?
- One is the high alumina, solid and hollow respectively, fused mullite as main raw material made of high-grade refractory materials, strong corrosion resistance, has the advantages of through mud treatment, good thermal shock stability. Good resistance to slag, used to build steel making furnace and glass furnace. High alumina brick is a kind of refractory material. Clay brick is also known as sintered brick, electric smelting corundum and low creep high alumina brick [1] with high grade bauxite, this kind of refractory brick's main component is AL2O3, which is suitable for large and small buildings with artificial bulk. High thermal stability. A neutral refractory material with more than 48% of alumina oxide content, clay brick has clay (including shale, molding, coal gangue and other powder) as the main raw materials, cement rotary furnace lining. The product has a small high-temperature creep, one is clay. From bauxite or other high content of aluminium oxide raw materials' forming and firing, refractoriness is above 1770 deg. High R.U.L and medium-sized hot-blast furnace is different firstly in the material, forming from drying and roasting
- Q: Would you please tell me how to use the simple method to identify shale brick, clay brick?
- Is the shale as raw material for high temperature baked bricks using shale and coal gangue, clay brick not dense surface, general clay brick for load-bearing structure, relatively thick, single shape; shale brick shapes, shapes with holes, in non bearing structure.
- Q: How to count the number of loading refractory bricks?
- Use one meter by one meter wooden raft-towing: use one meter raft-towing to count: Known your brick is T-3 standard bricks, each four layers lies down 15 and sidewards is 4 =64; according to 3.4kg, 47 clay bricks can hold 10 to 12 layers. According to the upper limit, each raft-towing can hold 2.3 tons
- Q: how to test the high alumina refractory brick mixed alumina?
- The first thing before producing bricks is to test whether the aluminum content reaches the standards, general testing on raw materials. Second: the shaped high aluminum brick will be tested in some professional equipment, you can know it from the professional inspection departments.
- Q: The foundation is made of Mu10, which is new clay brick and M7.5 cement mortar. What does it mean?
- Clearly pointed out that bricks are MU10's new clay bricks, cement mortar gradation is M7.5, according to this ratio to configure the construction
