Dhizaini neKuvakwa kweContinuous Hot-dip Galvanizing Annealing Furnace Lining yeStrip Steel
Pfupiso:
Maitiro ekugadzira galvanizing anokamurwa muzvikamu zviviri: galvanizing iri mumutsara uye out-of-line zvichibva pane nzira dzakasiyana dzekurapa dzisati dzagadzirwa. Chitofu chinogara chichipisa chinopisa chesimbi inotsvedza chinoshandiswa pakupisa chinodziisa maplate ekutanga egalvanizing ari mumutsara panguva yekugadzirwa kwegalvanizing iri mumutsara. Zvichienderana nemaitiro akasiyana ekugadzira, maovheni anotsvedza esimbi anotsvedza anogona kukamurwa kuita mhando mbiri: yakatwasuka uye yakatwasuka. Chitofu chinotsvedza chakafanana nechoto chinotsvedza chinotsvedza, chine zvikamu zvitatu zvikuru: chitofu chinodziyisa, chitofu chinodzikisa, uye chikamu chinotonhorera. Chitofu chinotsvedza chinonziwo shongwe, iyo inoumbwa nechikamu chinodziyisa, chikamu chinonyikisa, uye chikamu chinotonhorera.
Chimiro chesimbi inoputirwa nesimbi inoenderera mberi
Zvitofu zvechimiro cheshongwe
(1) Chikamu chekudziisa (choto chekupisa) chinoshandisa gasi repetroleum rakanyungudutswa semafuta. Zvitofu zvegasi zvakarongwa pakakwirira pemadziro echoto. Simbi inodziiswa nenzira inopesana nemhepo yechoto iyo inoratidza mhepo isina kusimba. Chikamu chekudziisa (choto chekupisa) chine chimiro chakaita sehorseshoe, uye pamusoro payo nenzvimbo yekupisa kwepamusoro apo maburi ekupisa akarongwa ane tembiricha yakakwira uye kumhanya kwakanyanya kwekukwesha kwemhepo, saka madziro echoto anoshandisa zvinhu zvisingaremi zvinodzivirira, zvakaita sezvidhinha zveCCEFIRE high aluminium light, zvidhinha zvethermal insulation, uye calcium silicate boards. Nzvimbo yekupisa (choto chekupisa) ine tembiricha yakaderera uye kumhanya kwemhepo kwakaderera, saka CCEWOOL ceramic fiber modules dzinowanzo shandiswa sezvinhu zvemadziro.
Zviyero zvemadziro echikamu chimwe nechimwe ndeizvi:
A. Pamusoro pechikamu chekudziisa (choto chekupisa chisati chatanga).
Zvidhinha zveCCEFIRE zvine aruminiyamu yakareruka zvinoramba kusimba zvinosarudzwa sejira repamusoro pechoto.
B. Nzvimbo yekupisa (choto chekupisa) nzvimbo yekupisa kwakanyanya (nzvimbo yekukweva strip)
Rutivi rwenzvimbo inodziya zvakanyanya runogara ruine zvinhu zvinotevera:
Zvidhinha zveCCEFIRE High Aluminum Zvishoma (nzvimbo inopisa yemadziro)
Zvidhinha zveCCEFIRE zvinodzivirira kupisa
Mabhodhi eCCEWOOL calcium silicate (pamusoro pemadziro anotonhora)
Nzvimbo inodziya zvishoma inoshandisa CCEWOOL ceramic fiber modules (huwandu hwe200Kg/m3) ine zirconium yekuisa mukati.
(2) Muchikamu chekunyikira (choto chekuderedza), chubhu yegesi inoshandiswa senzvimbo yekupisa yechoto chekuderedza strip. Machubhu egesi anopenya akarongwa pamwe chete nekukwirira kwechoto. Chidimbu chinomhanya uye chinopiswa pakati pemitsara miviri yemachubhu egesi anopenya. Choto chine gasi rekuderedza. Panguva imwe chete, kushanda kwesimba rakanaka kunogara kuchichengetwa. Nekuti kudzivirira kupisa uye kuputira kweCCEWOOL ceramic fiber zvinoderedzwa zvakanyanya kana paine kumanikidzwa kwakanaka uye mamiriro ekunze anoderedza, zvakakosha kuve nechokwadi chekuti kudzivirira kupisa kwakanaka uye kuputira kupisa kwechoto uye kuderedza huremu hwechoto. Zvakare, chidimbu chechoto chinofanira kudzorwa zvakasimba kudzivirira kudonha kweslag kuti ive nechokwadi chekuti pamusoro peplate yekutanga yegalvanized yakatsetseka uye yakachena. Tichifunga nezvekupisa kwakanyanya kwechikamu chekuderedza hakupfuuri 950 ℃, madziro echoto chechikamu chekunyikira (choto chekuderedza) anoshandisa chimiro chekupisa chakakwira cheCCEWOOL ceramic fiber blankets kana donje rakaiswa pakati pezvikamu zviviri zvesimbi inodzivirira kupisa, zvinoreva kuti jira reCCEWOOL ceramic fiber kana donje rakaiswa pakati pemaplate maviri esimbi. Iyo ceramic fiber interlayer inoumbwa nezvigadzirwa zve ceramic fiber zvinotevera.
Rutivi rwesimbi runodzivirira kupisa pamusoro pekupisa runoshandisa magumbeze eCCEWOOL zirconium fiber.
Chikamu chepakati chinoshandisa magumbeze eCCEWOOL ane fiber yeceramic yakachena kwazvo.
Rutivi rwuri pedyo nesimbi inotonhora pamusoro pechitofu runoshandisa donje reCCEWOOL rakajairika receramic fiber.
Pamusoro nemadziro echikamu chekunyikira (choto chekuderedza) zvinotevedzera chimiro chakafanana nechataurwa pamusoro apa. Choto chinochengetedza gasi rechoto rekuderedza rine 75% H2 uye 25% N2 kuti simbi yestrip irambe ichishandiswa zvakare uye iron oxide inoderedza pamusoro pesimbi yestrip.
(3) Chikamu chekutonhodza: Machubhu anopenya anotonhodza chidimbu kubva patembiricha yechoto (700-800°C) yechikamu chekunyorovesa (choto chekuderedza) kusvika patembiricha yekudzikisa simbi (460-520°C), uye chikamu chekutonhodza chinochengetedza gasi rechoto rinodzikisa.
Mupendero wechikamu chekutonhodza unoenderana nechimiro chakafukidzwa nemataira emagumbeze eCCEWOOL ane fiber yeceramic yakachena kwazvo.
(4) Kubatanidza zvikamu zvechikamu chekudziisa (choto chekupisa), chikamu chekunyorovesa (choto chekuderedza), uye chikamu chekutonhodza, nezvimwewo.
Zviri pamusoro apa zvinoratidza kuti maitiro ekuisa simbi inotonhorera inotonhora isati yaiswa galvanizing inopisa anofanira kupfuura nemaitiro, akadai sekuisa-kunyudza-kutonhodza, uye maitiro ese anoitwa mumakamuri akasiyana echoto uye akazvimirira, ayo anonzi chitofu chekupisa, chitofu chekuderedza, uye kamuri yekutonhodza zvakateerana, uye anoumba unit yekuisa strip inoenderera mberi (kana chitofu chekuisa). Munguva yekuisa strip, simbi inopinza inoramba ichipfuura nepakati pemakamuri echoto akazvimirira ataurwa pamusoro apa nekumhanya kwakanyanya kwe240m/min. Kuti dzidzivirire kuoxidation kwesimbi inopinza, zvikamu zvinobatanidza zvinoona kubatana pakati pemakamuri akazvimirira, izvo zvisingangodziviriri simbi inopinza strip kuti isaoxidized panzvimbo dzinobatana nemakamuri echoto akazvimirira, asiwo zvinovimbisa kuvharwa uye kuchengetedzwa kwekupisa.
Zvikamu zvinobatanidza pakati pekamuri rega rega rinozvimiririra zvinoshandisa zvinhu zveceramic fiber sezvinhu zvemukati. Zvinhu chaizvo uye maumbirwo acho ndeaya anotevera:
Mucheka uyu unoshandisa zvigadzirwa zveCCEWOOL ceramic fiber uye chimiro chakazara chefiber che tiled ceramic fiber modules. Kureva kuti, pamusoro pemucheka unopisa iCCEWOOL zirconium-containing ceramic fiber modules + magumbeze eCCEWOOL ceramic fiber akajairwa (pamusoro pechando).
Chitofu chechimiro chakachinjika
Zvichienderana nezvinodiwa zvetekinoroji zvakasiyana zvechikamu chimwe nechimwe chechoto chakatambanudzwa, choto chinogona kukamurwa kuita zvikamu zvishanu: chikamu chekupisa (PH section), chikamu chekupisa chisina oxidizing (NOF section), chikamu chekunyorovesa (chikamu chekuderedza kupisa che radiant tube; RTF section), chikamu chekutonhodza nekukurumidza (JFC section), uye chikamu chekutungamira (TDS section). Maumbirwo chaiwo e lining ndeaya anotevera:
(1) Chikamu chekupisa:
Pamusoro pechoto nemadziro echoto zvinoshandisa jira rechoto rakagadzirwa neCCEWOOL ceramic fiber modules nemagumbeze eceramic fiber. Jira iri pakupisa kushoma rinoshandisa jira reCCEWOOL 1260 fiber blankets rakamanikidzwa kusvika 25mm, nepo pamusoro pekupisa uchishandisa mabhuroko akapetwa eCCEWOOL zirconium. Jira riri pazvikamu zvinopisa zvakanyanya rinoshandisa jira reCCEWOOL 1260 fiber blanket, uye pamusoro pekupisa rinoshandisa ceramic fiber modules.
Pasi pechoto panoshandisa jira rakasanganiswa rezvidhinha zvevhu rakareruka uye mamodule e ceramic fiber; zvikamu zvinodziya zvishoma zvinoshandisa chimiro chakasanganiswa chezvidhinha zvevhu rakareruka uye mamodule e ceramic fiber ane zirconium, nepo zvikamu zvinodziya zvakanyanya zvichishandisa chimiro chakasanganiswa chezvidhinha zvevhu rakareruka uye mamodule e ceramic fiber.
(2) Chikamu chekupisa chisina oxidation:
Pamusoro pechoto panoshandisa chimiro chakafanana che ceramic fiber modules nemagumbeze e ceramic fiber, uye kumashure kwechoto kunoshandisa magumbeze e ceramic fiber anosvika 1260.
Zvikamu zvakajairika zvemadziro echoto: chimiro chechoto chakagadzirwa neCCEFIRE zvidhinha zvealumina zvakapfava + zvidhinha zveCCEFIRE zvakapfava zvinodzivirira kupisa (huwandu hwe 0.8kg/m3) + magumbeze eCCEWOOL 1260 e ceramic fiber + mabhodhi eCCEWOOL calcium silicate.
Matope emadziro echoto anoshandisa chimiro chemuchina wechoto chakagadzirwa nematombo eCCEFIRE akareruka ane alumina yakawanda + zvidhinha zveCCEFIRE zvakareruka zvine insulation yekupisa (huwandu hwe 0.8kg/m3) + magumbeze e ceramic fiber e1260 eCCEWOOL + mabhodhi eCCEWOOL ane calcium silicate.
(3) Chikamu chekunyikisa:
Pamusoro pechoto panoshandisa chimiro chepurasitiki chakagadzirwa nemagumbeze eCCEWOOL ceramic fiberboard.
