Does shuttle type kiln not come with corundum stone brick how many money a ton?

Shuttle type kiln is comprised by top of kiln wall, kiln and brick of kiln car line, shuttle type kiln not comes with corundum the price of stone brick compares clay, tall aluminous brick expensive, the price is in thousands of yuan roughly consummate 10 thousand yuan a ton, particular value need is mixed according to index use requirement.


Shuttle type kiln not comes with corundum stone brick is namely by corundum and Molaishi advocate the tall aluminous firebrick that brilliant photograph comprises, corundum not comes the firebrick that stone brick department points to to high pure or purer raw material is made. Among them the existence of impurity of oxide of low melting point, can reduce its high temperature capability. Mo Laishi brick should compare corundum common price of tall aluminous brick is a lot of higher. Function: The high temperature strength with be had better, fight high temperature creep gender, heatproof shake sex and fight aggressivity. The manage of Mo Laishi brick changes a kind of typical corundum function is: Al2O3 ≥ 85% , fe2O3 0.45% , apparent pore is led 19% , intensity of normal temperature compression is more than temperature of 55MPa loading bate to be more than 1700 ℃ , add a hot line to change (1600 ℃ , 3h) ﹣ 0.1% , heatproof shake sex (1100 ℃ water-cooling) be more than 30 times
The main measure of body of kiln of kiln of type of shuttle of design of dimension of shuttle type kiln is main the basis is asked by the crop of to calcine goods, the each respect element such as distributinging uniformity of ability of eject of product function, burner, temperature decides integratedly. (The supports high to kiln for kiln car mesa space height inside kiln of 1) shuttle type. The stow height that can allow according to material will decide kiln inside tall. As a result of its like magnesia brick loading bate temperature is mixed his firing temperature is adjacent, height of bricky stamp one's foot shoulds not be too tall, neigaotong often is in kiln 1 meter or so; And silica brick because temperature of its loading bate is high, neigaotong often is in its kiln 1.9-2.1 rice; Inside existing clay brick and tall aluminous brickkiln it is 1.5-1.9 rice and 1.1-1.5 rice high respectively. Next allows difference in temperature on bricky stamp one's foot also are a consideration inside kiln tall when one of influencing factor that should note. Kiln is tall increase, fluctuation difference in temperature is increased, cause easily firing quality is uneven. Of shuttle type kiln inside high design is 1508mm. (Of kiln of 2) shuttle type inside wide for the distance between wall of kiln of the two side inside kiln. Of kiln inside wide concern with the crop of kiln and permission difference in temperature. Crop increases along with the addition with wide kiln, too wide a central temperature on the low side. Kiln of contemporary shuttle type is used more flat wide model section design, is the aspect ratio of kiln H B commonly? 2, among them B is kiln inside wide, h is kiln inside tall. So of this shuttle type kiln inside wide design is 3016mm. (The choice of part of 3) arch center. The kiln of shuttle type kiln has vault and condole tip very two sort. Kiln of type of fireproof material shuttle, firing temperature is high, it is vault kiln more. Vault uses wedge brick build by laying bricks or stones to build, the option of arch center part is very important, arch center part is too small, arch brick gets power too big, still can produce next heavy phenomena in use process; Be like arch center part conversely big, arch radius is small, when be heated, arch brick expands, arch can be squeezed to rise and produce craze phenomenon, arch is exorbitant at the same time, hole is increased between vault goods, raise fluctuation difference in temperature. In part of arch center part is between ° of 60 ° ~180, among them the arch center part of 60 ° is used more. The arch center part of this shuttle type kiln uses 60 ° , its radius is 3016mm, arrow is 403mm high. (The cross section of kiln of 4) shuttle type accumulates F=4.154m2, the overall length of shuttle type kiln spends L= F V=7.222m. The operation circuit that through furnace of kiln of above shuttle type main measure designs, understanding needs to be treated seriously to every flow detail, not allow to ignore. Make us safe operate furnace of high temperature kiln, ensure person safety. The job with such better ability.
The kiln body space that shuttle type kiln uses pit of type of fireproof material shuttle (firing chamber) it is the space that comprises by top of kiln wall, kiln and place of brick of kiln car line. The inside kiln wall of shuttle type kiln is to use be able to bear or endure to build by laying bricks or stones of Mo Laishi brick builds the light qualitative firebrick with fast cold fast hot better performance, corundum and be become, its are exterior use the adiabatic insulation material such as cotton of siliceous aluminous fiber, siliceous calcareous plate, cliff to have thermal insulation. Of heat-insulation layer inside face but stickup 50mm is thick high temperature resistant fireproof fiber, in order to prolong the service life of adiabatic insulation material. To raise the intensity of kiln furnace and air-tightness, of kiln wall outside still often lap the board with large 5mm of a 3 ～ . And kiln of type of modern completely fireproof fiber shuttle is the inside in metallic crust secure fireproof fiber block directly with fireproof bolt. The orifice that burner brick and brick of cool spray head are used and observation hole still are opened on the kiln wall of shuttle type kiln, measure Wen Konghe press aperture to wait. Of course, when installing hole, the step that should notice not to let them affect kiln wall builds intensity and sealing. With other kiln furnace, kiln of compose of shuttle type kiln also is to have vault and condole tip very this two sort. Vault is to use wedge brick build by laying bricks or stones to become, arch horn is commonly between 180 ° of 60 ° ～ , among them the vault of 60 ° is used morer. Commonly used vault is fireproof material is light qualitative tall aluminous brick or corundum Mo Laishi brick, enclothe again above firebrick have the light qualitative insulation material such as cotton of siliceous aluminous fiber, cliff. Of course some shuttle type kiln still are stuck in the inside of vault brick those who have 50mm ply is high temperature resistant fireproof fiber, in order to reduce the accumulation of heat that kiln carries on the head, service life that comes loose to heat up and lengthen vault brick. The shuttle type kiln with contemporary broader section often uses the kiln of the top that make the same score condole to carry a structure on the head. The kiln of shuttle type kiln of structure of the top that make the same score condole is very fold a place to form by different light qualitative brick or fireproof fiber, with boom general its are alone the ground or it is into group ground hoisting on the girder of kiln body. Because want to undergo constant temperature change inside shuttle type kiln, should endure especially frequent, the heat that quickness heats and cools quickly bilges cold shrink action, and still play endure kiln inside of low frit volatile erode action, accordingly, the build by laying bricks or stones that how chooses form of kiln of shuttle type kiln correctly builds material is a notable problem. What the wall of kiln of traditional shuttle type uses is heavy qualitative saggar brick or fireproof tall aluminous brick, the temperature inside kiln can use corundum higher Mo Laishi brick, its harbour quantity of heat is very big, and kiln of contemporary shuttle type uses heat proof quality in great quantities good, accumulation of heat measures thickness of small, body brick of low light qualitative saggar or pledge gently fireproof tall aluminous brick and fireproof fiber, contemporary completely fireproof fibrous is energy-saving model the kiln body of shuttle type kiln is folded by fireproof fiber entirely piece reach its to secure machine plum place to form.
Kiln of large shuttle type divides composition by a few roughly, include system of kiln furnace steel structure, kiln fireproof material, wicket is opened close base of furnace of system of car of system, kiln car, pass in and out, kiln (contain basis of orbit of inside and outside) wait with system of system of flue, combustion, smoke evacuation system, control. The fireproof material composition of body of kiln of shuttle type kiln forms by the following parts normally: Body of car mesa above and body of build by laying bricks or stones of wall of the following kiln, build by laying bricks or stones of top of wicket, kiln and body of build by laying bricks or stones of kiln car mesa. Car mesa is normally the following kiln wall by heavy qualitative firebrick build by laying bricks or stones is built, the others 3 parts all the step of light simple fireproof stuff with good by heatproof shake sex, heat conduction and small coefficient of expansion is built. What the basis uses temperature is different, those who use different high strenth to light qualitative brick adds adiabatic fiber material or use the module of compound and fireproof fiber such as much brilliant Mo Laishi to make pit is firing space. Commonly used and fireproof material sees a table. Kiln wall, kiln carries fireproof material on the head is to pass special configuration to secure what go up in kiln system steel structure. Accordingly, kiln system steel structure has enough strength and stiffness to regard as prop up. Normally, height of furnace of kiln of steel structure basis is different, by the profiled bar of different specifications (multi-purpose I-steel or square steel tube) as pillar, the steel of different ply is pulled (δ=4~6mm) serves as wallboard, according to make choice of of kiln furnace width the profiled bar of different specifications serves as crossbeam. At the same time shuttle type kiln sets operation platform mostly. It is with kiln of type of shuttle of electric porcelain industry exemple, its kiln wall is fireproof material is commonly not come by light qualitative corundum stone brick (300~348mm)+ silicon acid is aluminous fireproof fiber (80~100mm) or Mo Laishi of light qualitative corundum brick (230mm)+ pledges gently tall aluminous brick (114mm)+ silicon acid is aluminous fireproof fiber (80~100mm) so two. At present fireproof fibrous product heats repeatedly in the course refrigeration and after sufferring high speed air current to erode, existing contractive big, easy ageing and produce fiber pulverization extremely easily to flake phenomenon. And firing to product of electric porcelain, pottery and porcelain arris type kiln, appeared the defect that this kind of circumstance can cause product exterior and function to go up, this heats completely unlike the metal or of heat treatment furnace heat object. The circumstance that once appear,fiber pulverization flakes, eradicate very hard, accordingly, asking to product exterior body of kiln of kiln of type of shuttle of porcelain of stricter pottery and porcelain, report is fireproof when the choice of material, very careful. Light qualitative brick adds fireproof fibrous kiln wall is the form with structure of ” of “ floating anchor, link will have between firebrick and kiln wall armor plate, regard kiln as the firm measure of the wall. Top of the kiln wall of arris type kiln, kiln and wicket, when with light qualitative corundum bricky build by laying bricks or stones builds Molaishi, often use gas rigid fireproof slop comes build by laying bricks or stones is built. This kind of slop asks to good step builds property, when can assuring appropriate construction already, ask (general requirement is in 90~120s) , ask to be in again construction can begin sclerosis after period of time, the normal temperature with good generation (or microtherm) stick receive strength (the requirement can achieve 0.5MPa above) a variety of norms that; can satisfy inside limits of 1000~1600 ℃ temperature to use from time to tome together.
Does shuttle type kiln not come with corundum stone brick how many money one ton? Price of Mo Laishi brick basically sees corundum index, still having is appearance, the welcome seeks advice from particular value, if do not know index can offer the use of shuttle type kiln, if use temperature, fire what goods, heatproof shake asks to wait a moment, the information that flourish Cheng Naicai can provide according to broad client recommends right product, greeting incoming telegram seeks advice.
