Product Description:

Clay bricks are the oldest, the most widely used refractory materials, to produce the raw material is clay mineral clay brick,

natural refractory clay generally can be divided into hard clay and soft clay, the refractory material in the manufacturing process,

the former is the most used after calcining clinker;The latter after adding water, plasticity is good, easy to sintering, used as a binder.

Refractory clay, clay clinker for orthopaedic binder made of Al2O3 content is 30-48% of refractory products.Clay bricks are the oldest, the most widely used refractory.In the 70 s China clay brick production accounts

for about 65% of the total output of refractory, countries such as America, Britain, Japan accounted for about 40 ~ 50%.

Raw material is clay mineral to make clay brick.Natural fire clay in general can be divided into hard clay and soft clay.

In refractory material in the manufacturing process, the former most used after calcining clinker;The latter after adding water,

plasticity is good, easy to sintering, used as a binder.China's shandong province and other places the chamotte (hard) and

suzhou clay (soft) is a famous high quality refractory clay.Clay minerals are mainly kaolinite (2 sio2, Al2O3 · 2 h2o),

dickite (composition and kaolinite and same, but different lattice constant), montmorillonite (4 sio2, Al2O3 · 6 h2o) and mica mineral.

Q:can the red brick be used as refractory brick?
Can not replace! The high temperature will make it burst. Coefficient of thermal expansion is not enough
Q:What is the name of the white clay refractory brick
The name of white clay is kaolin clay
Q:Small size black brick can replace refractory bricks for wood burning fireplace?
No. Because black brick has no fireproof function. The result of using the black brick can only be counterproductive, and which is also a waste of time and fuel.
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:Is the quality of refractory brick influenced if it is soaked by water
No refractory brick is not afraid of water
Q:what kind of refractory brick is suitable for 1300 degrees converter?
magnesia-carbon brick, you can also use MgO-Al2O3 castable, it is good too.
Q:Is fireclay brick acidproof? Does clay brick anti corrosion when it's used to build chimney lining?
Refractory bricks anti acid and alkali after high-temperature calcination, and anti-corrosion won't be a problem
Q:application of phosphate refractory bricks
The 4 properties of phosphate refractory bricks: (1) high strength wear resistance (2) and chemical erosion (its alkali resistant ability is better than that of clay brick and high alumina brick) (3) and good thermal shock resistance (4) high load softening temperature in rotary kiln, kilneye, kiln Zone door cover, cooling machine and lining refractory brick falling parts easy to loose
Q:does the electric kiln burner need to be sealed?
seal when open the kiln, and observe the temperature, when the temperature reaches a point, you can move the firebrick away, and continue observing the temperature to decide whether to seal it or not, but do not seal it completely, repeat the procudure until reach the sinter point or skill requirement.
Q:how much is the content of the high alumina of refractory brick?
linear change on reheating is small and Slag resistance is good, matte smelting, good thermal shock resistance used refractory materials should be resistant to high temperature: In front of the furnace, the temperature can reach 1800, copper blowing. The maximum temperature in the smelting furnace area is on the top, pyro-refining and electrorefining, magnesia chrome brick, magnesia chrome castable, magnesia alumina brick. The commonly used refractory materials is direct-bonded magnesia-chrome bricks, which has large volume density. manufacturing technique of copper smelting consists of five parts, Clay brick
