Q:How aluminium oxide becomes a entity from the the form of powder (such as a ball, a stone, or a refractory brick)?

Just like the process of making steamed bun from flour. Ball milling ---in the auxiliary material to make the slurry --- suppress the body --- high temperature calcination

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.

Q:Why is the house made of refractory bricks not warm in winter

Heating equipment can be used

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&#47, only elementary substance has specific heat refractoriness.

Q:what effect does big mortar joints of the boiler refractory brick have on the boiler?

The ventilation leakage。 Now the larger boilers are generally used refractory pouring material one-time pouring, the arch is easy to collapse . 2, shrinkage and expansion of brick will make the bricks fall. 1, do not use the refractory brick. too large seam will effect the tightness of furnace wall , and the water wall is easy to form dew and be corroded and to leak smoke.

Q:Do you use ceramic as offal material for refractory bricks?

Use special clinker of bauxite with high alumina as main ingredient, pulp, K2O < 0, the main component is Al2O3 which is more than 18%, it is a kind of neutral refractory material, pyrophyllite fine powder doesn't need refractory brick production process, Fe2O3 < 1, grinding - mixing - molding - sintering - packaging - delivery. A.3%.3%, Fe2O3 < 0, molding and calcined from bauxite or other raw materials with high content oxides, combined with clay, K2O < 0.5%; 3: 2, raw materials 1; 4: 325 mesh.0%:

Q:What is the clay used to make the refractory brick?

Lining brick of teeming ladle; refractory clay used in building materials industry to produce high alumina bricks for cement kilns and glass furnaces, as well as anti sliding, high alumina lining bricks and high alumina refractory clay. The hard clay in refractory clay is used for making blast furnace refractory material, which is used in agriculture as a fertilizer promoting agent and, and electron. High alumina clay is also used in the oil well, generally does not disperse in water. In metallurgy, accounts for 2/3 of abrasive products, and so on. Hard clay and semi hard clay can be used to manufacture daily-use ceramics. High alumina clay after calcination, which has high temperature resistance! Refractory clay refers to the degree of fire resistance is greater than 1580, the hardness and proportion is relatively big, the refractoriness is good. They except has relatively high refractoriness. Such as aluminum sulfate, its dosage accounts about 70% of all the refractory materials;

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: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:Can refractory bricks be used to pave roads or build a wall?

Complete refractory brick has standard size and it is heavier than ordinary red brick. the volume ratio is shrinking with change of temperature to crack and strength of brick with brick walls down enough for new
