Welcome to visit our factory.

Q:What types of building blocks do you have?: Ordinary housing: building brick (clay brick), and non sintered brick (sand lime brick, fly ash brick, cement brick, etc.)

Q:What material does tile tunnel kiln use to replace the refractory brick to have better insulation effect and save the maintenance and prolong the service life?: Yes, but the cost is high, refractory material should be the most affordable at present.

Q:What is the difference between a clay brick and a red brick?: Burning bricks are generally low temperature clay brick, brick, brick high.

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:When using high alumina refractory brick, what are the reasons leading to the decline of the performance of high alumina brick?: The excess air coefficient is controlled in 1, in order to prevent producing water cracks in the production of high aluminum refractory brick from, control the water absorption of 2 grade clinker of bauxite with high alumina below 4%-5%. 1-1,the water absorption of the tube mill should also be controlled below 6%, and adjust thermotechnical, making the high alumina refractory brick burning be in the stable weak oxidizing atmosphere. should be 2

Q:Tunnel kiln firing refractory brick by 0 against the good rely on: Modern advanced kiln has high temperature strength and good thermal shock resistance, better environmental protection, is the most economical and efficient kiln. (3), good resistance to gas erosion, due to tunnel kiln's flue gas discharge temperature is generally not higher than 250℃. In order to guarantee the normal temperature system and pressure system of the kiln. Its firing temperature is at 1200-1900℃: (1) or even higher, the requirement for the firebrick, compared with the intermittent kiln, is an important thermal equipment in refractory industry. It is a kind of energy-saving kiln. Tunnel kiln is a kind of kiln that can continuously produce and has high degree of automation.

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:The state's policy on clay bricks: Also known as clay brick brick, is a man-made small bulk building, clay brick clay (including shale, coal gangue powder) as the main raw material, through mud processing, molding, drying and roasting, solid and hollow.

Q:What are the weak points of clay bricks?: SiO2 and Al2O3 in clay bricks form eutectic, low melting point silicates with impurities during sintering, and are surrounded by mullite crystals. Clay brick belongs to weak acid refractory products, it can resist acid slag and acid gas corrosion, and its resistance to alkaline material is a little worse. The thermal performance of clay brick is good, it is fast and cold. The clay brick refractory brick and be roughly the same, up to 1690~1730 DEG C, but the load softening temperature is 200 degrees Celsius above the low brick. Because clay bricks contain crystalline Mullite with high refractoriness, they contain nearly half of the amorphous glass phase of low melting point.

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.
