The principle that insulation material chooses vitreous frit kiln because frit kiln the environment with located insulation material is harsher, choose insulation material to should follow the following principle so: (1) has good heat preservation performance, namely coefficient of thermal conductivity is entered λ≤0.14W/(m·K)(350K);(2) is had certain fireproof degree, fall in compound heat preservation especially, each heat-insulation layer should satisfy the requirement of interfacial temperature, meet otherwise function of great influence heat preservation, even invalidation;(3) has high temperature stability, can assure to be below use temperature condition not pulverization, do not fall off;(4) has better chemical stability, must not corrode in use process or corrode noumenon structure, and can secure fireproof material;(5) has joint to fight impact strength and lighter self-prossessed;(6) material to configure plan to should have economy certainly. Bottom of the big Xuan top of frit kiln, pool, Chi Bi is medicinal powder the place with much heat, add up to occupies body of kiln of whole frit kiln to come loose hot 85% the left and right sides, and kiln substance appearance conducts heat means conducts heat for convection heat exchange and radiate, this is concerned with the exterior temperature of kiln body and environmental temperature, the difference in temperature of the exterior temperature of kiln body and outside ambient is smaller, heat loss due to radiation is lower. Accordingly, to achieve the goal with energy-saving heat preservation, drop the temperature of kiln substance appearance. And of the temperature of kiln substance appearance after heat preservation reduce have very big concern with sex of insulation material content, especially the coefficient of thermal conductivity of insulation material, both the concern that shows positive to close. Vitreous frit kiln the heat preservation of each place should notice the heat preservation of each place and kiln of introductory glass frit the following item. 1. The principle that heat preservation place defends namely with can be being protected, enlarge heat preservation face as far as possible. 2. The interfacial temperature that notes heat preservation brick does not want those who exceed material to bear temperature. 3. Wall of big Xuan, parapet, port, regenerator Xuan is the heat preservation after the kiln that bake. 4. Kiln furnace expands seam place not heat preservation. It is vitreous frit kiln below the heat preservation structure with each commonly used place. (Heat preservation of 1) big Xuan 1. 300mm silica brick + 35mm quartz is arenaceous + 65mm pledges gently silica brick + 20mm asbestine mud. 2. 300mm silica brick + 50mm quartz is arenaceous + 65mm pledges gently silica brick + 65mm pledges gently argillaceous brick + 20mm asbestine mud. 3. 300mm silica brick 10 40mm quartz is arenaceous + 115mm pledges gently silica brick + 65mm pledges gently silica brick + 20mm asbestine mud. 4. 300mm silica brick + 30mm silicon is qualitative sealed makings + 115mm pledges gently silica brick + 50mm silicon pledges heat-insulation layer expects. (2) parapet heat preservation 1. 350mm silica brick + 65mm pledges gently silica brick + 50mm silicon calcareous plate. 2. 300mm silica brick + 6mm silicon is qualitative sealed makings + 65mm pledges gently silica brick + 115mm pledges gently tall aluminous brick + 50mm silicon calcareous plate. (Brick of corundum of zirconium of frit of report of heat preservation of 3) pool wall + 35mm zirconium pounds dozen of makings character + 115mm pledges gently argillaceous brick + armor plate of 50mm silicon calcareous plate. (Heat preservation of 4) pool bottom 1. Brick of corundum of zirconium of 70mm report frit + 35mm zirconium pounds dozen of makings character + 300mm is pouring big brick + 280mm pledges gently argillaceous brick + 10mm asbestine board + 8mm armor plate. 2. Brick of corundum of zirconium of 70mm report frit + 35mm zirconium pounds dozen of makings character + brick of 40mm zirconium stone + 35mm zirconium pounds dozen of makings character pouring big brick + 280mm pledges gently argillaceous brick + 10mm asbestine board + 8mm armor plate. (Silica brick of 250mm of Xuan of port of 5) port, ① of regenerator heat preservation + 30mm quartz is arenaceous + 115mm pledges gently silica brick + 20mm asbestine mud. Silica brick of 350mm of ② port wall + 6mm silicon is qualitative sealed makings + 65mm pledges gently silica brick + 50mm silicon calcareous plate. Silica brick of 250mm of ③ regenerator Xuan 10 30mm quartz is arenaceous + 115mm pledges gently silica brick + 20mm asbestine mud. A of ④ regenerator wall 230mm clay brick + 115mm pledges gently argillaceous brick + 240mm builds a brick; Brick of regenerator wall clay + 230mm pledges gently argillaceous brick + coating of 20mm heat preservation. Fireproof material occurrence craze, fall off, easy how to wear away to do? Want to solve a problem thoroughly, need to be dug from germ, the analysis gives real reason, flourish Cheng Naicai is engaged in be able to bear or endure service of timber production, research and development is old, can solve all sorts of difficulty problems of liner of furnace of high temperature kiln, welcome broad new old friend to seek advice reach technical communication.
