Q: Which thermal stability of clay bricks and high alumina bricks is good?: High alumina brick is made of superfine alumina, fused corundum and fused mullite as main refractory materials. The product has the advantages of high temperature, little creep, strong corrosion resistance and good thermal shock resistance, and is suitable for large and medium-sized hot blast stoves.

Q: What kind of refractory brick is suitable for 1400 degrees shuttle kiln?: Corundum mullite is also the principle about.2 can be. use high aluminum brick, which heat storage capacity is big, but the price is more expensive, and the chilling and heating performance is not good, the .

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 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: which kind of refractory bricks do coke oven and oxtongue brick belong to ( ) A, silica?brick B, clay brick C, high alumina brick: Beef tongue is to regulate the flow of gas, gas flow is not the same, so is the temperature, so choose the temperature resistance brick which is clay brick only.

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: 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: What are the sizes and sizes of clay bricks?: At present, with the minimum size of the maximum size of the market, for the maximum size of the clay brick, there are 600*250*200mm, 180*115*90mm, 300*300*55mm, and the minimum sizes 150*150*150mm, 235*115*55mm and so on, the construction industry the most basic materials for clay brick, must use in daily life is very broad.
