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 is the best color of refractory brick
Date red is better.
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: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:What are the advantages and disadvantages of clay refractory bricks?
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.In the temperature range of 0~1000 DEG C, the clay brick volume increases with temperature uniform expansion, linear expansion curve approximates a straight line, the line expansion rate is 0.6%~0.7%, about half of the brick. When the temperature reaches 1200 degrees Celsius and then continues to heat up, the volume will begin to shrink from the maximum expansion. The residual shrinkage of clay brick results in the cracking of masonry joints, which is a major drawback of clay bricks. When the temperature is above 1200 degrees, the low melting point of the clay brick gradually melts because the particles are very close to each other due to surface tension, resulting in volume shrinkage.
Q:How to wipe off the white paint on the refractory brick (red).
Cover the wall gap with tape. . Then paint the bricks. Finally, tear the tape off. .
Q:Where the refractory bricks rider bricks that are used for building arch and vault should be put?
Arch and vault shall be built simultaneously from both sides of the arch of the foot to the center of symmetry, when masonry, inverting concentric reducer of arch brick is prohibited; the lock should be driven into the brick arch from the side, if the last rider brick can't be driven from the side, you can process the first 1-2 brick to make the size of the lock and the lock buckle equal, and then drive suitable rider brick from top, and use steel plate to jam-pack the side; dismantling arch tire must be performed after all rider bricks are driven and lock brick arch foot ditch masonry is completed and the final tightening nut for skeleton retractor rear.
Q:does all the refractory refer to refractory bricks when making steel?
refractory materials not only refers to the refractory brick, but also includes like castable refractory and a number of bulk cargo and ramming mass The desulfurization agent belongs to metallurgical auxiliary material
Q:Why is the house made of refractory bricks not warm in winter
Refractory bricks are not used in the house, but used in a large boiler inner
Q:What is the color of the refractory brick to repair the same color as the 1400
Smash the same brick into fine powder
