Tall aluminous firebrick is it is alumina content the products of siliceous aluminous fireproof data in 48% above, it is main raw material with aluminous alumina commonly, join other white makings, additive and bond classics burden, mix the refine, fire after shaping and into. Scope of application of tall aluminous firebrick is wide, the industrial kiln such as rotary kiln of kiln of blast furnace of iron of usable Yu Lian, Jiao Lu, hot-blast stove, converter, glass, cement furnace, tall aluminous firebrick regards kiln furnace as liner, good, service life grows use effect, it is the first selection firebrick that furnace of kiln of a lot of industry uses fireproof data.
The manufacturer home of tall aluminous firebrick has a lot of, that tall aluminous firebrick how many money a ton? Most propbably this is the problem that a lot of users care relatively, before knowing value of tall aluminous firebrick, we are necessary to say to affect the factor of price of tall aluminous firebrick, because understood these aspects only, the brick of tall aluminium of choose and buy with nicer gift.
Common the price of tall aluminous brick: One class tall aluminium: More than 10 yuan together, 2 class tall aluminium: 10 yuan control. Tall aluminous brick is the neuter and fireproof data that content of a kind of alumina obtains 48% above, by alumina or other alumina content taller raw material classics shapes to be become with to calcine. Thermal stability is tall, fireproof degree in 1770 ℃ above. The sex that fight broken bits is better, the liner that is used at build by laying bricks or stones to build furnace of circumgyrate of forge of steel-making electric stove, glass, cement to wait.
From the point of market level, the price of tall aluminous firebrick is much more unequal. According to the quality index requirement of GB2988-2012, value of market of tall aluminous brick is 3000 yuan about / ton, value of market of brick of one class tall aluminium is more than 2000 yuan about / ton, value of market of brick of 2 class tall aluminium is more than 1000 yuan about / ton, value of market of brick of 3 class tall aluminium is more than 1000 yuan about / ton. The price of different when the choose and buy area is additionally different also.
1, dimension of tall aluminous firebrick
Dimension of tall aluminous firebrick has measure of standard firebrick dimension and different firebrick, different firebrick needs to use a pattern when make, raise the cost of a mould with respect to need at this moment, if different firebrick crop is bigger, general firebrick produces manufacturer to receive a mould to expend no longer, if output is less, can add collect mould fee.
2, manage of tall aluminous brick changes target
Tall aluminous qualitative firebrick is the main fireproof product in firebrick, tall aluminous brick differs because of aluminous content its function also has certain difference. Tall aluminous brick is used in different kiln furnace, its manage changes target the requirement is different also. Accordingly, when brick of tall aluminium of choose and buy, must inform firebrick to produce manufacturer, the utility of tall aluminous brick reachs the function of a need, the tall aluminous brick with facilitating appropriate choose and buy.
3, tall aluminous brick makes cost
Make the fireproof raw material that tall aluminous brick uses wait because of size of composition content, granuality, raw material produces area and firebrick production area to differ, firebrick makes cost more or less also have difference. Luck fertile the Gong Yi that teems with at aluminous mine, can make all sorts of tall aluminous bricks.
4, firebrick produces manufacturer
The manufacturer that tall aluminous brick produces on market is very much also, resemble luck at present fertile fireproof, service client is numerous, seasoned, manufacturer actual strength is abundant, often produce the firebrick with a variety of qualitative material for the user, understand a variety of kiln furnace performance characteristics, can offer reasonable kiln furnace to use tall aluminous brick for the user solution, assure quality of tall aluminous brick.
These affect above namely the element of price of tall aluminous brick, so, tall aluminous brick how many money a ton? We are with respect to brick of one class tall aluminium accurate, consult the price is controlled in thousands of yuan, price of brick of one class tall aluminium offers this level only referenced.
Differ according to resource condition and product demand, can use the following kinds of raw material: With hydrous aluminium oxygen is mineral (one water aluminous stone, 3 water aluminous stone) the tall aluminium that is main composition is aluminous; Silicon line stone a group of things with common features mineral (include stone of line of cyanite, andalusite, silicon to wait) ; Synthesize raw material artificially, wait like corundum of frit of Mo Laishi of industrial alumina, synthesis, report. Earth of vanadium of Chinese tall aluminium is resourceful, quality of a material is good, producing area basically distributings in and other places of Shanxi, Henan, Heibei, Guizhou, Shandong. Earth of produces tall aluminous vanadium, basically be one water aluminous stone (α-Al2O3·H2O) with kaolinite two kinds of mineral mixture.
