Brick of heat preservation of heat insolation of line of rotary kiln kiln

Line of fireproof material kiln designs as energy-saving as heat preservation rotary kiln to be by wide application in the process such as the dry, agglomeration of raw material and to calcine inside rotary kiln reach the application in mineral treatment industry. Adopt the concept that heat preservation of build by laying bricks or stones of double deck line designs especially, discuss the sources of energy that how raises kiln furnace to use efficiency, those who lengthen fireproof material liner enlist in army life, and corresponding auxiliary and mechanical equipment. Pass rotary kiln liner optimize construction and efficient heat preservation the application of fireproof material, OK and managing many energy cost. Until go up century the fifties, monolayer lining design is the commendation that construction of rotary kiln liner designs all the time. Be in normally inside kiln firing belt use magnesium is qualitative fireproof material or magnesian chromic brick, and the other part application in kiln furnace is pouring makings and argillaceous brick. This kind of method is in on century 50 made a change to 60 time. Choice diatom mud pledges installation of heat preservation brick is in rotary kiln furnace, this is one kind can enlist in army below 900 ℃ temperature, and intensity of normal temperature compression can achieve the heat preservation brick of 5.5MPa, the promotion that is this kind of function makes double deck can be used actually of line build by laying bricks or stones to be on the rotary kiln that the diameter is 2 meters. Current, more high quality insulation material is in on century 80 time are inchoate be come out by development, this kind of material is had can enlist in army below 1000 ℃ and intensity of normal temperature compression can achieve 18MPa. The success of research and development of this kind of material makes the design of line of double deck build by laying bricks or stones can be used to be on the rotary kiln that the diameter is 4 meters.
The rotary kiln of structure of rotary kiln liner and active to the requirement to calcine of fireproof material lime presses crop cent to produce a few kinds of kiln such as 300t, 400t, 600t, 800t, 1000t, 1200t for day commonly model, the temperature that to calcine takes is controlled in 1350 ℃ . Rotary kiln removes ordinal cent to be discharge from kiln head end end, cooling zone, firing belt, warm-up belt, into makings end, each paragraphs of temperature inside kiln differs to 1350 ℃ from 1000 ℃ , not identical also to the requirement of fireproof material. Fireproof data supports not only inside kiln high temperature concussion, and need to bear of stock erode wear away, the stress that kiln body roll produces, accordingly not only to be able to bear or endure the manage of material changes index to have firm demand, still ask when to construction build by laying bricks or stones is built, need to guard a pass strictly. The rotary kiln of lime of active of domestic to calcine is at present fireproof the configuration plan of material is as follows: Discharge end: Low cement tall aluminium is pouring makings add fiber of 3 ％ steel; Cooling zone and firing belt: The brick of magnalium pointed spar of dry build by laying bricks or stones adds light qualitative tall aluminous brick; Warm-up height is lukewarm paragraph: Tall aluminous brick; Warm-up takes low temperature paragraph: Clay brick adds brick of light qualitative clay; Enter makings end: Low cement tall aluminium is pouring makings add fiber of 3 ％ steel. Besides, the over all dimension of firebrick also have corresponding demand: Dimension public errand: The requirement of dimension public errand that uses in different position is different, ordinary control is in ± 2mm; Edge horn damages: Allow edge damage commonly in long 40mm and deep 5mm, horny caustic is in cold hot side be patient of is in, the length of 3 arris and do not exceed 50mm; Interstitial: Not parallel of be patient of exists at using the break of the face, the subtle break on bricky face allows to exist.
The adiabatic layer structure of rotary kiln of brick of heat preservation of heat insolation of line of rotary kiln kiln spreads felt of a fireproof fiber to rely on furnace casing first, pledge with diatomite brick, clay next brick of adiabatic heat preservation or bleach the adiabatic brick build by laying bricks or stones such as bead brick to build, density of usable also bulk pledges gently for 0.8g/cm3 fireproof and pouring makings whole irrigates.
The fireproof material that Rong Cheng fact regards major as produces manufacturer to be able to produce the brick of fireproof, heat preservation of a variety of different types, product type basically undertakes classified from material character with construction means, the line of the products that my factory produces is all ready, OK and contented show level what the place of hot project facilities such as furnace of kiln of all sorts of power plant boiler, industry needs is high temperature resistant requirement, product quality is worth your reliance.
