Price of brick of kiln furnace heat preservation how many?

Energy-saving environmental protection is the development trend of furnace of high temperature kiln, heat preservation is energy-saving cannot leave the product such as brick of light qualitative heat-insulating material, heat preservation, price of brick of kiln furnace heat preservation how many?


What field does kiln furnace heat preservation basically include? Kiln wall heat preservation, kiln carries heat preservation and conduit heat preservation on the head. Reach kiln body heat preservation with kiln wall especially among them two compare a key. If kiln carries heat preservation effect on the head not beautiful, quantity of heat passes heat-insulation layer a large number of be lost arrive outside kiln, cannot be made full use of by kiln furnace and conduit of more than heat, can affect product quality directly.
What does brick of kiln furnace heat preservation have? Porosity of firebrick of light qualitative clay is bigger, the organization is loose, cannot use at direct contact slaggy the place with liquid state metal; Mechanical intensity is inferior, cannot use at bearinging structure; Wear-resisting performance is very poor, unfavorable use at be being contacted with charging, wear away serious place. What brick of light qualitative clay allows in it only is tall bear in temperature, ability produces strong adiabatic result. In kiln furnace, regular meeting of general liner place classics gets the direct contact of blaze and slag, apply to heavy qualitative brick only. Brick of light qualitative clay basically applies in the thermal insulation of hot project facilities and industrial kiln furnace, can use at having stock of melt of intense high temperature to erode to reach erode the place of action, a fireproof coating, reduce be eroded by slag and soot of heat vital energy erodes, decrease mar. Of course, in be not fusion furnace, do not contact with blaze. Temperature upper limit in the kiln furnace under brick of light qualitative clay, can come with brick of light qualitative clay entirely build by laying bricks or stones is built.
Brick of light qualitative tall aluminous heat preservation calls tall aluminium adiabatic brick again, alumina content is in 48% above, main the light qualitative fireproof material that constitutes jointly by Molaishi and vitreous photograph or corundum. Bulk density 0.4 ～ 1.35g/cm3. Porosity 66% ～ 73% , compression intensity 1 ～ 8MPa. Heatproof shake performance is better.
Brick of Mo Laishi heat preservation with Molaishi (the expensive aluminous simple fireproof stuff that 3Al2O3 · 2SiO2) gives priority to brilliant photograph. General alumina content is in 65% ～ 75% between. Mineral composition divides Molaishi outside, contain alumina among them inferior person still contain a few glass photographs and Fang Shiying; to contain alumina taller person still contain a few corundum. Brick of Mo Laishi heat preservation can be used at liner of furnace of high temperature kiln directly, use extensively already at the liner of shuttle type kiln, roller path kiln, glass and petro-chemical kiln furnace at present.
Silicon pledges adiabatic firebrick pledges gently silica brick, finely silica basically is used to make raw material when making, its are critical granuality does not exceed 1mm normally, and the grain that is less than 0.5mm among them not less than 90% . Of light qualitative silica brick fireproof spend as identical as composition common silica brick to differ not quite, why because air hole is very much, the reason compression intensity, sex that fight broken bits, sex that fight corrupt be inferior to common silica brick.
Alumina is hollow ball brick with alumina hollow ball is main raw material, add industrial oxidation aluminium powder and bond in proportion, shape via mixing agitate, suppress, dry hind the fire inside the furnace of kiln of type of high temperature shuttle in 1600 ℃ and into. Diameter of hollow ball bead is alumina commonly 5 ～ 0. 5mm, dosage is in 70 ％ of 65 ％ ～ , dosage of alumina fine pink 35 ％ of 30 ％ ～ ; Bond dosage 5 ％ .
Price of brick of kiln furnace heat preservation how many? According to above a few sort, 1000 yuan control a ton, still have thousands of, get on 10 thousand yuan even a ton, detailed price invites report to seek advice.
Major of flourish Cheng Naicai produces brick of kiln furnace heat preservation, what ensured kiln furnace effectively is normal move, reduced prediction of a person's luck in a given year of quantity of heat, reduce prediction of a person's luck in a given year of quantity of heat to be able to be achieved compared to the same period 25% , raised utilization rate effectively, promote a product quality at the same time. Welcome everybody the incoming telegram seeks advice and choose and buy, flourish Cheng Naicai is dedicated be able to bear or endure material territory is old,
