Refractory brick is dense shaped refractory material. With high refractoriness and mechanical behavior under high temperature, refractory brick is the necessary material of high-temperature services, mainly used for industrial furnaces and kilns and thermal equipment.

Refractory brick has wide applications, mainly used in metallurgy, construction(cement and glass), petroleum, chemical industry, electric power and machine building.

Q: Which is more useful, aerated concrete block or clay brick?: How to evaluate the porous brick right (aerated concrete block), the practicability of the clay brick, brick which is first aerated concrete block, aerated concrete block and clay brick is the coexistence of wall materials, only the current use rate than the aerated concrete block of clay solid brick.

Q: What are 85 bricks, 95 bricks and standard bricks? What are the specifications?: 95 bricks are standard bricks.Specifications：95 bricks: 240*115*53mm85 bricks: 216*105*43mmArtificial brick, small bulk building, divided into brick (clay brick) and non sintered brick (sand lime brick, fly ash brick etc.), commonly known as brick.

Q: Do refractory bricks need to be sent to the lab to test after arriving the site?: Other is nothing, generally it does not need, whether single weight meets the requirements, whether the appearance is regular, usually only to see whether the size is standard, it is set in the procurement

Q: 90 porous brick and ordinary shale brick, clay brick difference: Porous brick is the original clay brick (now don't let in) and shale increased by a certain gap, but it is also the porosity, thickness is 90, not 53 of the original, there are also some differences in the use of solid brick and. Not for underground use.

Q: How about clay bricks?: Fired ordinary brick is one of the indispensable building materials in production and life, but its quality is not good or bad in the absence of professional equipment. Now to introduce a little trick:According to the main raw materials for clay brick, shale, coal gangue and fly ash brick. Mainly in our local clay brick. According to the compressive strength of weathering resistance of radioactive material and qualified brick, according to the size deviation, appearance quality, efflorescence and lime burst into superior products, first-class products, qualified three quality grades.

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: T38 size of high alumina refractory brick: 230*114*65/55

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: How to use the winding packaging machine to pack refractory bricks: Over 150KG the most common winding machine can pack, if it is light or the goods scatter, then add capping or pre-drawn device is all right.

Q: Are clay bricks radioactive?: Basically, any substance has radiation, because natural conditions contain a lot of radioactive particles, and even the body itself has reflective particles, such as carbon 14, but the dose is safe.
