Q:how much fireclay is needed for 10000 refractory bricks?
The amount of mud used for T-3 refractory brick is 0.3KG. if the tiler is skillful, the furnace should have joint of 2mm.
Q:How to increase the service life of high temperature refractory bricks?
The wedge brick should contain the brick surface distortion, decrease scrap rate high temperature refractory brick is refractory with a certain shape and size, the error of symmetry and concentric reducer's size differences. The correctness of shape of the straight refractory brick should include the straight of the intersection and the distortion of brick's face. Under the premise of ensuring the service life, the key to improve the efficiency of manufacturers, and have the correct shape and precise size. This is to ensure that the product is qualified, refractory brick in addition to planning a reasonable scale, that is, the scale of the allowable error.
Q:does the furnace wall use refractory bricks to keep the heat? Or use the insulation material to keep heat ?
Both needed! In fact, the insulation material contains refractory brick.
Q:How to make refractory bricks? ? ?
Solution of the production of refractory brick raw materials
Q:What is the name of the white clay refractory brick
There are several kinds of white clay, Guangxi clay, Suzhou clay, kaolin
Q:How can refractory bricks be punched?
Use percussion drilling to hit
Q:What material are used to burn firebrick?
Alkaline series of refractory bricks /, can be classified into five types. Refractory bricks are generally made from refractory clay (white clay) or other refractory materials. Refractory brick according to the composition of refractory material, that is, silicon aluminum refractory brick / carbon containing refractory brick / thermal insulation refractory brick/ zirconium containing refractory brick /
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:What should be paid attention when the refractory brick kiln furnace reaches a certain service life and will be removed?
Q:The service life of the refractory brick of the intermediate frequency electric furnace, how long is the replacement period.
There is no standard. As long as the induction coil can be fixed and furnace lining can be built, the service life will be different. Replace it if it's broken, and there is no problem to take it apart. Buy a backup. And the textures of refractory brick are not the same in different places.
