Q:What are the ingredients of brick?
Is the most traditional brick masonry material, its composition is clay as the main raw material gradually to the development of industrial waste utilization of coal gangue and fly ash, and by solid and hollow porous to development, development by sintering to non sintering.
Q:What kind of material is good to be laid on the kiln car, refractory brick?
Use blankets to suspend ceiling, and modules for wall
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:can Methanol burn refractory brick?
Generally speaking, all the fuel can burn, mainly to see the calorific value and consumption ratio
Q:How many degrees of refractory brick if its surface turns red, how to test the temperature of refractory brick after it is burnt to red.
If the raw materials are different, then the redness is different under different temperatures.
Q:What material does tile tunnel kiln use to replace the refractory brick to have better insulation effect and save the maintenance and prolong the service life?
The price is high, but the the service life is not longer than the clay brick, some use high aluminia brick. Currently, there are no refractory products that can replace refractory bricks. The effect is good of choosing fireclay brick with high strength dense, low porosity clay brick. We have maken several lines of refractory bricks. Actually, if you choose good refractory brick, the service life will be very long. The kiln temperature is not high.
Q:What is the role of refractory brick, whether is there any books to introduce refractory bricks
Refractory bricks are generally used to build a hearth. Such as, boiler, furnace (molten metal), air heating furnace etc, the furnace need refractory bricks to bulid.
Q:Whether the cement kiln refractory bricks belong to hazardous waste or not?
Refractory brick produce dust hazards if it is broken, It is also should be paid attention to that if is refractory brick containing chromium, which will easily produce Cr VI when met with water, Cr^6+ material produced by magnesia chrome bricks is difficult to be damaged in the environment, which in many cases will exist in nature for a long time, continue to endanger human health. Chromite, as the raw materials to make magnesia-chrome brick, often exists in the form of trivalence (Cr203), is not toxic, nor carcinogenic, but in the cement rotary kiln high temperature oxidation atmosphere, it reacts with alkali metal oxide in cement materials, will produce chromic acid and alkali acid which is harmful to people's health. There are MgOIn contained in broken magnesia-chrome bricks, whose water solution is weakly alkalinity and generally will not easily produce K2cr207. K2Cr04 is a kind of weak oxidaiblity chemical compound, which has high chemical stability. It is very difficult to be reverted to non-toxic trivalent chromium when it blends into the environment. In many cases, these chemical compounds containing Cr VIcompounds will exist in nature stably, causing long-term pollution to the environment. This kind of harm is sustainable. The second reason that is very serious is that the high grade chrome ore is less and less in the world, forcing refractory manufacturers to find and develop
Q:Are buildings allowed to use red bricks?
Clay brick is forbidden to be used by the state, whether red or green. Red and cyan are just the difference between making techniques. Now also produces appearance and clay sintering, red brick like silicate sintered brick can be used.
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;
