Industrial kiln furnace belongs to high temperature equipment, separate facility is not to resist high temperature, erode and tatty, need refractory products to provide protection, select material undeserved or what construction issue can affect furnace of high temperature kiln is normal move.
The chamber of a stove or furnace uses armor plate to coil to make and be become, as temperature elevatory, intensity of the chamber of a stove or furnace is reduced. Undertake to the product roast when, wind is warm can achieve 1000-1700 ℃ normally, if do not increase protection, kiln furnace will burn out quickly. Liner protects the kiln body, service life that prolongs lining namely, normal production is needed. Additionally 10 thousand, fireproof data is set inside, still have heat preservation effect, reduce kiln furnace be lost, reduce specific fuel consumption, raise kiln heat heat to put rate, raise yield, reduce cost. Meanwhile, fireproof material also has accumulation of heat, remove heat to exchange action. 1. Concept: Industrial furnace kiln is make by fireproof material, use at the equipment of calcination stock or fire product. 2. The 3 element of kiln: Temperature. Atmosphere. Pressure. 3. The classification of kiln furnace: A. Can divide according to the sort of calcination material for: Kiln of pottery and porcelain. Cement kiln. Vitreous kiln. Enamel kiln; B. Can divide according to heat source for: Blaze kiln and electric heat kiln; C. The amount that presses a passageway can divide for: Only way kiln. Double talk kiln and much talk kiln; D. Can divide by disparate industry for: Kiln furnace and more fractionize types, for example cement rotary kiln. Vitreous pool kiln. Iron and steel uses blast furnace, converter to wait. 4. Kiln furnace structure: General by firing chamber. Combustion facilities. Drafting apparatus, carry 4 parts such as equipment to comprise. 5. Heat source: Blaze kiln: The fuel of furnace of general and large kiln attachs most importance to oily, light diesel fuel more or gas. Natural gas; Electric kiln: Use electric stove silk more. Silicon kryptol or 2 silicon change molybdenum to make calorific component. The charging of industrial furnace kiln basically has fireproof, heat preservation and other and auxiliary stuff. Or say to build charging, basically be products of of all kinds and fireproof data. Adiabatic brick and blame finalize the design be able to bear or endure material, be like fireproof and pouring makings. But model. Pound dozen of makings. Filler, fireproof fiber.
Why does industrial kiln furnace use fireproof data a lot of industries have operating below high temperature, if train iron and steel to prep above of 1600 ℃ centigrade. Below this kind of high temperature, burn with average data, used pit is provided, cannot crack with average data make. General material falls in such temperature, early melted. To make beacon fire kiln is mixed production tool, these industries must use a kind of special data, call fireproof material. This are fireproof material wants resist at least centigrade the temperature of 580 ℃ . Below this kind of high temperature, it does not fuse or bate, can satisfy the following requirement: Especially furnace of kiln of firebrick build by laying bricks or stones, after the course is used for a long time, do not answer to be changed apparently, especially its bulk should be not changed. If charging rises in price, or contractive, will written guarantee to kiln body construction becomes an influence, even attaint, cave in. After kiln furnace is built, adds raw material and the product that produce and by-product, no matter they are solid. Liquid or gas, after be being contacted with fireproof material, below high temperature condition, can drop its melt temperature. This kind is destroyed be called chemistry to erode. Why industrial furnace kiln should use fireproof data, what demand is there? Furnace of requirement industry kiln should have with fireproof material be able to bear or endure enoughly the mechanical intensity of Wen Xinghe high temperature, and when high temperature bulk wants stability. The better corrode that fight broken bits reachs the sex that fight broken bits. Flue gas erodes ability, if nonferrous metal is phyletic much, fusion method is different, consequently industrial kiln furnace is much and complex, want special attention to satisfy different product to the choice of lining material. The specific technology of different technology asks. To ensure the build by laying bricks or stones inside furnace builds mass, the function index of select material must accord with active country to the standard sets or design a requirement, have good construction performance.
Line of kiln of the glass inside furnace of kiln of industry of fireproof material sort destroys commonly used industrial furnace kiln all element: Chemical harm. Machine wash. Spend jolt and intertropical utility to wait, of skill of kiln furnace talent adopt basically have the following kinds: (1)Al2O3-SiO2 series; Basically use at maintaining argillaceous brick and silica brick. (2)Al2O3-ZrO2-SiO2 series; Bases is zirconium stone brick and aluminous corundum brick. 3)ZrO2-SiO2 series; (4)MgO-Al2O3.MgO-Cr2O3.MgO-Sioz series; (5) insulation material. 2. Use at the fireproof talent skill of cement kiln. The fireproof data that cement plant uses (1) is alkalescent and fireproof talent skill; Alkalescent and refractory products has: Magnesian chromic brick. Magnesia brick. Pointed spar brick. Dolomite brick. Magnesian chromic brick also divides common magnesium chromic brick. Look for magnesian chromic brick directly. Look for magnesian chromic brick directly. (2) aluminous silicon fastens fireproof talent skill; Cement kiln fastens fireproof material with silicon aluminium, divide general clay brick. Besides tall aluminous brick, have special requirement. (3) heat insulation is fireproof material; Contain siliceous lid and brick of light qualitative heat preservation above all. (4) is pouring makings. Cement kiln is used pouring expect those who contain high strenth, tall alkalinity is pouring makings. Be able to bear or endure knot skin is pouring makings. Low cement is fireproof and pouring makings. Kiln mouth alone casting is pouring makings. Gush coal canal is pouring makings. 3. Second wind canal is pouring makings.
The exterior temperature standard of industrial furnace kiln it is furnace of a kind of figuration, it is comprised by industrial boiler setting, it can make blaze stabilizes combustion, it is certain to finish conduct heat process. According to the function of burner wall cent is firewall and heat preservation wall, firewall should have enough use temperature (the use temperature) that the temperature that contractive quantity will burn not to exceed 2% again normally on international regards heat insolation as fireproof material, adiabatic wall has very good heat preservation property, can bear already high temperature has lesser hot loss again, temperature of the wall outside general requirement is 60? Under 80 ℃ , highest temperature does not exceed I00 ℃ . In GBGB3486-83 " assessment industry is reasonable guideline of the technology that use heat " in have specific provision, . So, when considering boiler setting, should consider wall not only lukewarm, decide its material is qualitative even, also should consider its to conduct heat at the same time function, in order to decide the structure of boiler setting and ply. Why should industrial furnace kiln use fireproof data? Kiln is the important equipment of the product that passes high temperature calcination or fire, below high temperature little not blaze is eroded. Erode, because this needs protection of fireproof material liner, fireproof liner through wearing away liner implementation provides protection to equipment.
