Sirocco conduit basically includes sirocco to be in charge of (contain flow backwards cease wind is in charge of) , sirocco raises canal and sirocco to surround a canal. Liner structure is body of cirque build by laying bricks or stones commonly, each trident opening position (show sirocco raises a canal, flow backwards rest to wind is in charge of and surround canal and sirocco director to join a department) use assorted brick (the orthogonal photograph that appearance is body of two cirque build by laying bricks or stones as string of 1000 cash body) ; In the technology of pipeline of sirocco of suddenly dagger article that introduces in last few years, the semicircle on trident opening position uses condole to hang smooth arch, like issueing semicircle to use firebrick and conduit brick.
Liner construction uses fireproof spray layer more + thermal insulation + firebrick job layer, also have need not of spray layer. The capable person that thermal insulation employs is qualitative a variety of, like felt of fiber of fireproof pottery and porcelain + brick of light qualitative clay (or bleach bead brick light qualitative tall aluminous brick, gently character) or siliceous calcareous plate + brick of light qualitative clay (or bleach bead brick light qualitative tall aluminous brick, gently character) etc. Working layer firebrick uses argillaceous brick or tall aluminous firebrick.
When sirocco conduit liner has spray layer, the coating that use spray looks for a circle, to guide with spray layer face build by laying bricks or stones is built; When the coating that do not have gush, to guide with envelope face build by laying bricks or stones is built. Sirocco surrounds tubal cross section common step becomes polygon,
Sirocco conduit spray first the semicircle below gush, hind the semicircle on gush, if coping has the in season after spray of fiber of fireproof pottery and porcelain. Spray looks for round method to basically have two kinds: One kind is to use radian board to look for a circle; One kind is installation center bracket, use radius annulus lever to look for a circle. Former and simple convenient, but spray center and spray layer ovality are controlled hard, also affect the control of the ovality when build by laying bricks or stones of layer of thermal insulation, job is built; Although latter gives or take a lot of trouble, raise construction cost, but spray center (also be bricklaying center is fiducial) can exact location, spray layer ovality is controlled easily, build firebrick to create good condition for build by laying bricks or stones.
Zhengzhou flourish fills what fireproof material serves as major to be able to bear or endure the product of fireproof heat preservation that material produces manufacturer to be able to produce more than 40 kinds of different types, product type basically is from sort and recipe scale undertakes distinguishing, line of the products is various, basically can satisfy show level boiler, what steel-making chamfer place needs is high temperature resistant requirement, product quality is worth your reliance.
