Firebrick is one kind has certain measure and appearance to be able to bear 1580 ℃ come the fireproof data products of 3000 ℃ , its suitable scope is wide, the industry such as rotary kiln of kiln of the bag of steel of canister of blast furnace of iron of usable Yu Lian, Jiao Lu, hot-blast stove, molten iron, torpedo canister, steel-making, bag intermediate, converter, glass, cement kiln furnace, firebrick regards kiln furnace as liner, good, service life grows use effect, it is the first selection that furnace of kiln of a lot of industry uses fireproof data refractory products.
Existing firebrick shapes the mould is when the firebrick that make, often use static pressure undertake squeezing ramming, in the process of squeezing ramming, especially poorer to fluidity fireproof material cannot flow to be in to position of the horn side the mould, place of the horn side the firebrick that brings about suppress to shape is disloyal, affect the quality of firebrick. Additional, shape in suppress when need arises a brick, if use a machine to undertake automation is produced, often can install firebrick to carry a device on the head in mould lower part (product line of if ZL2016102584317 is full automatic fireproof material) perhaps give a brick in setting of mould lower part implement; If use handiwork to undertake the build by laying bricks or stones of special shaped brick is built, use what ZL201320536438.2 place makes public to adjust a structure more. Use manual build by laying bricks or stones to build, the advantage is to be able to reduce damage second rate, defect is efficiency low, use automation machinery to although can improve efficiency,have production, but motivation is used up bigger.
Firebrick mould is the tool that firebrick uses when production, put the fireproof raw material that when producing firebrick, uses into the mould, through compressor pressurization, make firebrick shapes, firebrick mould but the demand according to the client is custom-built treatment, especially abnormity dimension. The mould can make firebrick adobe better shape, size is exacter, ensure firebrick is in the dimension after fire, ensure firebrick builds the integrality when using in build by laying bricks or stones.
The importance of the mould is self-evident, the mould is having main effect to the quality of firebrick adobe, if firebrick produces a mould to have a problem, bring about quality of despotic firebrick adobe possibly to be not stabilized, affect the use of firebrick.
When producing firebrick, in suppress craft, get on firebrick mould installation to compressor above all, be sure to retain accent of pressure head, model, give a brick implement 3 person central line coincide. If not coincide, quality of influence firebrick adobe, cause crackle, damage even equipment. When hardness not when divide evenly, mould surface can appear ” of “ fatigue hole and ” of “ undee chamfer, send craze of the adobe in exert brick process. The mould puts foot (reduced scale) rate, taper and on size error affect base substrate over all dimension directly whether satisfy booked tolerancepublic errand requirement. Of the mould bright and clean attenuation of degree of the pressure when the influence pressurization shapes and the size that bricky force carries on the head when giving a brick. Because the adobe when pressurization has existed up and down,great pressure is differred, create bulk density difference easily. Because give brim of the base substrate when the brick to get,chafe force, underside is postponed force action, when attrition force and thrust are too big, cause firebrick adobe craze easily. When clearance existing between mould and modular casing, pressurization and remove the metropolis when pressing to had produced big flexibility to be out of shape, cause adobe to produce fore-and-aft crackle or twist. Motherboard is stuck makings the blemish such as face of meeting generation hemp. Lid of motherboard, model and modular wall gap are too big, can make adobe produces flash.
Firebrick shapes mould occurrence attaint, what affect firebrick adobe quality is not stable, right firing the firebrick quality after is influential also, the production that because this is fireproof,requires a brick should ensure firebrick shapes above all mould.
The general application of firebrick, the manufacturer home of firebrick is very much also, so firebrick how many money a ton? This is the problem that consumer cares most.
Firebrick price influencing factor:
The manufacturer home of the firebrick on market is numerous, manufacturing firebrick also has each different, in understanding firebrick how many money a ton before, we are necessary to its the price undertakes simple analysis.
1, quality actor bad
Quality actors or actress bad decides firebrick value directly, the firebrick with good quality, service life is long, use effect is good, the industrial kiln furnace that can be an user prolongs service life, reduce the expense of fireproof material.
2, brand actual strength
Manufacturer of the firebrick on market is more, service client is numerous, seasoned, understand the performance characteristics of kiln furnace, the firebrick that recommends for the user is reasonable, assured firebrick quality.
3, market competition ability
Market competition is big, the manufacturer that explains production sells firebrick is much, a lot of distributors give firebrick to sell, lower firebrick price, can cause so with material qualitative firebrick, the price has difference each, as a result cannot buy wanted firebrick truly at the client.
4, raw material cost
The fireproof raw material that the firebrick that make uses, area of size of composition content, granuality, crude place of production different, firebrick cost price is different also, then firebrick price also can be affected. Of the development as economy and situation of fireproof data trade austere, a lot of manufacturer cannot assure the quality of fireproof raw material, strong supplier, the treatment that is firebrick is made become backup force.
5, firebrick material is qualitative
Firebrick regards industrial kiln as the liner of furnace, the firebrick that different kiln furnace chooses is different, the firebrick that the different position of kiln furnace uses also differs, because this follows the principle of reasonable, economy, different area should choose reasonable firebrick, firebrick price also differs to choose different capable person to pledge and change somewhat because of what area reachs kiln furnace.
