- Q:What is the specific heat of a refractory bricks (clay)?
- Approximately it's about 2000; M3 specific heat is wrong with this argument, two degree clay is 1730 degrees, three degree clay is 1690 degrees, clay bricks are mixture, bulk density, 1900KG/, only elementary substance has specific heat refractoriness.
- Q:What is the role of refractory brick, whether is there any books to introduce refractory bricks
- Just as its name implies it is a fire burning, making stove is very good
- Q:How good is the hardness of corundum refractory brick?
- The basic materials of corundum refractories are fused corundum or sintered corundum. the refractory brick containing more than 90% of Al2O3 is called corundum refractory brick. so, corundum refractory brick. Corundum has a high hardness (9 level of Mohs hardness) such as zirconium corundum refractory brick. Corundum refractory brick is resistant to acid well and melting point is also high, also known as pure alumina refractory brick products, , it has a good effect. These are closely related with the structure of the Al - 0 key, titanium corundum refractory brick, and other basic slag. It is used in high temperature oxidizing atmosphere or in reducing atmosphere. the metal and glass solution have good stability. a-Al2O3 is the main material of high temperature refractory brick and high temperature electrical insulating material .
- Q:Shale brick and clay brick? Answer before you know it
- Is the shale as raw material for high temperature baked bricks using shale and coal gangue, shale sintered porous brick, hollow shale brick, shale brick, high insulation, water wall and other types of modular brick.
- Q:What is the upper limit of high temperature resistance of refractory bricks and refractory soil?
- In a variety of colors; if it has small amounts of Ti4 and Fe2, then it is blue, vanadium and other trace elements, brown red color, which include red, yellow and other colors, the Ural mountains of Russia; corundum is aluminum oxide (Al2O3)mine. Some crystals contain six symmetrical distribution and other needle like rutile inclusions, they are called star ruby or sapphire stars, but because they often exist fracture, black and other colors on the bottom surface of the colorless or rhombohedral decent form polysynthetic twin, a drum shaped six square column, iron, yellow, blue and green, the color of sapphire is decided by the chemical composition contained in titanium, no cleavage, gray, yellow sapphire etc.. Sapphire often is known for its color name, such as white sapphire, sky blue, including South Africa as the main origin of the Transvaal, more than 1500 sapphire calls corundum, brown. Corundum has glass luster, and is common seen in alluvial placer, purple, named ruby. Produced igneous and metamorphic rocks, which are relatively barren. Sapphire is all colors corundum gems except red series of corundum gems. Does ruby refer to corundum with all red hues? No, violet sapphire is mainly used as high-grade abrasive, its red is mainly caused by the chemical composition of trace elements chromium, blue sapphire is the most popular in the world, pink. The crystal belongs to the three party system, green. Usually it is white, gold sapphire, are precious gems, they can produce six star awn, some are needle or clintheriform, green sapphire. Aggregation is block or columnar.
- Q:Can refractory bricks be used to pave roads or build a wall?
- Refractory bricks are used to build a house, no problem
- Q:Is refractory brick afraid of rain?
- High alumina clay is not afraid of rain, but covering is better, magnesium carbon refractory brick had better not be rained.
- Q:Lining of refractory bricks in rotary furnace
- The lining of the converter is probably a furnace, but if it is changed at least to see the material and the use of it. There are a lot of damage to the lining, such as: The total impurity content reduces to 2%, lining life will increase 20%-40%; CAO in brick is of 60%-80% content , lining life are the highest; also some other proper index can not be ignored such as bulk density,heat/thermal shock resistant performance,porosity,thermal expansion,fracture resistace,volume stability,Slag resistance,and so on. In addition, lining erosion rate is the largest when the basicity of slag is 1, with the increase of basicity, erosion rate decrease rapidly, the temperature can cause cracks spalling of lining. At the same time, the building process is also very important.
- Q:What matters should be noticed when using clay refractory bricks in a glass kiln?
- There are a variety of products for the production of shaped and unshaped refractory clay, such as blast furnace insulation and high alumina bricks. Brick products include refractory clay bricks, plastic materials for overload, refractory clay and high alumina casting materials, etc.. In the amorphous part, if to support the horizontal induction furnace and the straight induction furnace lining, such as refractory clay and high alumina plastic
- Q:What is the life of an old fashioned refractory brick kiln transformed into a flat topped tunnel kiln? what material should be used to transform the old fashioned refractory bricks vault kiln to flat tunnel kiln, and how long is the service life?
- Hanger plate
