High temperature resistant brick calls firebrick. It is to use saggar mix into to enter clinker (to calcine and classics the clay after smashing) junior travel agitate, suppress shapes, dry hind gets via to calcine finished product. Additionally still silicon is mixed character tall aluminous brick. Can divide according to the brand for firebrick of SK32, SK34, SK36, SK38, SK40. The position that firebrick basically uses at lining, flue, chimney to wait, by its appearance and norms can be divided for standard type and abnormity two kinds big. The norms of standard firebrick is millimeter of ×65 of millimeter of 230 millimeter ×114, abnormity firebrick undertakes by demand the spot is machined or requirement manufacturer is supplied.
Firebrick presses his fireproof degree can be divided for common model (fireproof degree is 1770 ℃ of 1580 ～ and advanced firebrick (fireproof degree is 2000 ℃ of 1770 ～ ) two kinds. By its chemical function can be divided again for acidity, alkalescent with neuter 3 kinds.
My company is the manufacturer of firebrick major production that builds a plant nearly 30 years, basically have SK series firebrick, fancy firebrick, one class firebrick, 2 class firebrick, we raise different firebrick; ceaselessly new technology, the pottery and porcelain of demand; country that new technology; makes product quality satisfied different client and regular surveillance of center of fireproof material product quality supervision and inspection examine, assured the stability of product quality.
Firebrick has wear-resisting damage, anti-corrosive, fight flake, low creep, thermal shock stability is good, service life is the 1.5 times; of common product basically is used at blast furnace, hot-blast stove, furnace of charcoal element roast, furnace of charcoal element to calcine, jiao Lu, contain steel barrel, mould system, boiler, cement kiln, vitreous kiln and facilities of all sorts of kiln furnace liner and hot project, apply to metallurgy, mechanical, building materials, cast, pottery and porcelain, electric power, oil, the industry such as chemical industry.
The manage of firebrick of SK32, SK34, SK36, SK38, SK40 changes target.

Firebrick price?
Firebrick how many money a ton? 1000 multivariate - 10000 multivariate have. The price of firebrick reachs norms requirement, firebrick to need to use the respect such as place to differ according to making body of raw material, brick, the price also has very big difference.
Firebrick application:
The structural data that firebrick uses in all sorts of hot project facilities and high temperature container to serve as counteractive high temperature and liner, main application limits has the liner of the furnace such as the puddling in metallurgy industry, steel-making, furnace of kiln of the cement kiln of building materials industry, pottery and porcelain, glass kiln reachs liner, the sintering furnace in branch of exercise of the high temperature in mechanical industry, heating furnace and covering layer.
The flow of manufacturing technology detail of firebrick:
Firebrick is to use fireproof raw material (aggregate) , complementary makings adds bond to deserve to compare according to certain proportion via mixing refine, make big shape, dry wait for craft again classics agglomeration or the bricky system that agglomeration is made and do not become.
Preparation of makings of pink of —— of raw material choice (broken, smash, screening) —— of —— scale burden mixes refine —— to make big shape —— of agglomeration of —— dry —— examines —— is packed
1, because the firebrick raw material that make is more, because choice of this raw material is affirmatory,make why to plant the firebrick of norms index is hand-in-hand of travel raw material choose. What notice here is the grain content of the content of raw material and burden and size.
2, process of powdery makings preparation is raw material farther broken reach choose, with achieving made demand.
3, scale burden is make up raw material, bond and water accurately by certain proportion, in order to ensure the function of firebrick in use.
4, mixing refine is have raw material and bond and water mixture equably, make pug more even change.
5, the pug after mixing refine needs quiet place period of time, after making pug sufficient and even, be in shape, increased the strength of the plasticity of pug and refractory products.
6, shaping is in setting pug the pattern in the regulation, the appearance with deciding product, dimension, cause density and strength.
7, the adobe water content after shaping is higher, in firing before undertake beforehand dry, can avoid to be in firing when because had warmed up,fast water divides acuteness eduction and cause crackle.
8, after adobe classics is dry, water divides content to need to fall to 2% enter kiln furnace to undertake agglomeration, agglomeration process can make adobe becomes compact, intensity increases, volume is steady, become the firebrick that has certain standards demand.
9, the firebrick with good fire is in after giving pit, the examination of the member that pass qualitative check square but put in storage.
What does firebrick raw material have?
The raw material of the firebrick that make has a variety of, from chemical angle for, always the simple substance of high melting point, compound can be told as raw material; from mineralogical angle, always tall fireproof those who spend is mineral the raw material that also can serve as firebrick, what does the raw material of common firebrick have, general component is: Earthy, stone is qualitative, arenaceous qualitative, opaque and other.
(1) is earthy have: Kaolin, clay and diatomite
(2) stone has character: Stone of spar of needle of stone of line of aluminous alumina, fluorite, cyanite, andalusite, silicon, magnesian olivine, vermiculite, Molaishi, chlorite, dolomite, magnalium and silica, cordierite, corundum, Jiao Baoshi, zirconium
(3) is arenaceous qualitative: Quartz is arenaceous, magnesia, chromic mine is arenaceous wait
(4) opaque: Pink of aluminium powder, silicon, silicon small pink
(5) is other: Colophony of bitumen, black lead, phenolic aldehyde, pearlite, float bead, cement of collosol of water glass, silicon, aluminous acerbity calcium, shaly ceramists, aluminous collosol, carborundum, hollow ball
Firebrick ties kind:
In fireproof material introduction, the combinative means cent that we had mentioned fireproof data is united in wedlock for pottery and porcelain and be united in wedlock directly, and means of these two kinds of union and manufacturing firebrick craft are having close relationship. Now nowadays, to make be able to bear or endure material uses a target (kiln furnace) the respect such as the advantage of the addition of service life and the maintenance in use process, the production of firebrick also gradually change, if present compound tall aluminous brick, compound silica brick is waited a moment.
