Dhizaini uye Kuvaka Kwekuenderera Kupisa-dip Galvanizing Annealing Furnace Lining yeStrip Steel
Muchidimbu
Iyo inopisa-dip galvanizing process yakakamurwa kuita zvikamu zviviri: in-line galvanizing uye kunze-kwe-line galvanizing zvichibva pane dzakasiyana nzira dzekutanga kurapwa. Inoramba ichipisa-dip galvanizing annealing furnace ye strip steel mudziyo unobatidza unopisa kupisa-dip galvanized mahwendefa epakutanga panguva ye-in-line galvanizing process. Zvinoenderana neakasiyana maitiro ekugadzira, strip simbi inoenderera ichipisa-dip galvanizing annealing mavira anogona kupatsanurwa mumhando mbiri: yakatwasuka uye yakachinjika. Choto chehorizontal chakanyatsofanana nechoto chakatwasuka-kuburikidza chinoramba chichikwirisa, icho chine zvikamu zvitatu zvakakosha: choto chekupisa, choto chekudzikisa, uye chikamu chekutonhodza. The vertical furnace inonziwo tower furnace, iyo inoumbwa nechikamu chekudziya, chikamu chekunyorova, uye chikamu chekutonhora.
Lining chimiro che strip simbi inopfuurira annealing furnaces
Tower-structure furnaces
(1) Chikamu chekudziya (preheating furnace) inoshandisa liquefied petroleum gas sehuni. Zvinopisa gasi zvakarongwa pamwe nekukwirira kwemadziro echoto. Simbi yemutsetse inodziiswa munzira inopesana negasi revira iyo inopa isina kusimba oxidizing mamiriro. Chikamu chekudziya (preheating furnace) chine chimiro chakaita sebhiza, uye kumusoro kwayo uye tembiricha yakakwira iyo nzvimbo yekupisa inorongedzerwa ine tembiricha yakakwira uye nekumhanya kwakanyanya kwekuyerera kwemhepo, saka dhizaini remadziro evira rinotora zvinhu zvinoreruka zvisingaremi, seCCEFIRE yakakwira aluminium zvidhinha zvidhinha, tembiricha yesimbi yekalsiyamu, zvidhinha zvinopisa. Iyo yekudziya chikamu's (preheating furnace) yakaderera tembiricha zone (strip simbi inopinda munzvimbo) ine yakaderera tembiricha uye yakaderera mhepo inoyerera scouring kumhanya, saka CCEWOOL ceramic fiber modules inowanzoshandiswa semadziro emadziro zvinhu.
Zviyero zvemadziro emadziro echikamu chimwe nechimwe ndeaya anotevera:
A. Pamusoro pechikamu chekupisa (preheating furnace).
CCEFIRE yakakwirira-aluminium lightweight refractory zvidhinha inosarudzwa sechigadziro chepamusoro pechoto.
B. Chikamu chekudziya (preheating furnace) tembiricha yakakwira (strip tapping zone)
Iyo yakakwirira tembiricha yenzvimbo lining inogara ichiumbwa neanotevera akaturikidzana ezvigadzirwa:
CCEFIRE Yakakwira Aluminium Yakareruka Zvidhinha (iyo inopisa pamusoro pemadziro emadziro)
CCEFIRE insulation zvidhinha
CCEWOOL calcium silicate boards (iyo inotonhora pamusoro pemadziro emadziro)
Iyo yakaderera tembiricha zone inoshandisa CCEWOOL ceramic fiber modules (vhoriyamu density ye200Kg/m3) ine zirconium yekuisa.
(2) Muchikamu chekunyura (choto chekudzikisa), iyo gasi inopenya chubhu inoshandiswa senzvimbo yekupisa yechoto chekudzikisa mitsetse. Iwo gasi anopenya machubhu akarongwa pamwe nekukwirira kwechoto. Mutsetse unomhanya uye unopisa pakati pemitsara miviri yemachubhu anopenya gasi. Iyo choto inopa kudzikisira gasi rechoto. Panguva imwecheteyo, kushanda kwakanaka kwekumanikidza kunogara kuchichengetwa. Nekuda kwekuti kupisa kwekudzivirira uye kupisa kwekushisa kweCCEWOOL ceramic fiber zvakadzikiswa zvakanyanya pasi pekumanikidzwa kwakanaka uye kudzikisa mamiriro ekunze, zvinodikanwa kuve nechokwadi chekudzivirira kwakanaka kwemoto uye kupisa kwekudzivirira mhedzisiro yevira rechoto uye kuderedza huremu hwechoto. Zvakare, iyo vhezheni yevira inofanirwa kudzorwa zvakanyanya kudzivirira kudonha kwe slag kuti ive nechokwadi chekuti pamusoro peiyo galvanized yepakutanga ndiro yakatsetseka uye yakachena. Tichifunga nezve tembiricha yepamusoro yechikamu chekudzikisa hachipfuure 950 ℃, iyo inonyura chikamu (cheto yekudzikisa) madziro echoto anotora yakakwira-temp insulation layer yeCCEWOOL ceramic fiber magumbeze kana donje rakaputirwa pakati pezvikamu zviviri zvesimbi isingadziviriri, izvo zvinoreva kuti CCEWOOL ceramic fiber gumbeze kana maviri simbi simbi yakamiswa. Iyo ceramic fiber interlayer inoumbwa neinotevera ceramic fiber zvigadzirwa.
Iyo simbi isingadziviriri simbi shizha pane inopisa pamusoro inoshandisa CCEWOOL zirconium fiber magumbeze.
Iro repakati rinoshandisa CCEWOOL yakakwirira-kuchena ceramic fiber magumbeze.
Iyo yakatsetseka padyo neinotonhora pamusoro pesimbi ndiro inoshandisa CCEWOOL yakajairwa ceramic fiber donje.
Iyo yepamusoro uye madziro echikamu chekunyura (kudzikisa vira) tora chimiro chakafanana nepamusoro. Icho choto chinochengetedza gasi rechoto rinodzikisira rine 75% H2 uye 25% N2 kuti ione kudzokororwa kwesimbi ye strip uye kudzikiswa kweiron oxide pamusoro pesimbi ye strip.
(3) Kutonhodza chikamu: Iyo mhepo-yakatonhorera inopenya machubhu inotonhorera mutsara kubva muchoto tembiricha (700-800 ° C) yechikamu chekunyorova (reduction furnace) kune zinc pot galvanizing tembiricha (460-520 ° C), uye chikamu chekutonhora chinochengetedza kudzikisira gasi revira.
Iyo lining yechikamu chekutonhora inotora iyo tiled chimiro cheCCEWOOL yakakwirira-kuchena ceramic fiber magumbeze.
(4) Kubatanidza zvikamu zvechikamu chekupisa (preheating furnace), chikamu chekunyura (kuderedza moto), uye chikamu chekutonhora, nezvimwe.
Izvo zviri pamusoro zvinoratidza kuti nzira yekumisikidza yesimbi inotonhora-yakakungurutswa simbi isati yapisa-dip galvanizing inoda kufamba nenzira, sekudziya-kunyura-kutonhodza, uye maitiro ega ega anoitwa mune akasiyana dhizaini uye akazvimirira makamuri echoto, anodaidzwa kunzi vira rekupisa, choto chekudzikisa, uye kamuri yekutonhodza zvichiteerana, uye ivo vanoumba chidimbu chinoramba chiripo. choto). Munguva yekugadzira annealing, iyo strip simbi inoramba ichipfuura nepamusoro-yakataurwa yakazvimirira makamuri echoto pahupamhi hwekumhanya mutsara we240m/min. Kuti udzivise oxidation ye-strip simbi, zvikamu zvinobatanidza zvinoona kubatana pakati pemakamuri akazvimiririra, izvo zvisingangodziviriri simbi ye strip kubva pakuiswa oxidized pamajoini emakamuri akazvimirira echoto, asi zvakare inovimbisa kuvhara nekuchengetedza kupisa.
Zvikamu zvinosungirirana pakati pekamuri yega yega yakazvimirira shandisa ceramic fiber zvinhu semidziyo yekuisa. Iwo chaiwo zvinhu uye zvimiro ndeaya anotevera:
Iyo lining inotora CCEWOOL ceramic fiber zvigadzirwa uye yakazara-fiber chimiro chetaera ceramic fiber modules. Kureva, iyo inopisa pamusoro peiyo lining ndeye CCEWOOL zirconium-ine ceramic fiber modules + tiled CCEWOOL yakajairika ceramic fiber magumbeze (inotonhora pamusoro).
Horizontal chimiro choto
Maererano nezvinodiwa zvakasiyana-siyana zvetekinoroji zvechikamu chimwe nechimwe chechoto chakakomberedzwa, choto chinogona kukamurwa kuita zvikamu zvishanu: preheating chikamu (PH chikamu), isiri-oxidizing kupisa chikamu (NOF chikamu), chikamu chekunyorovesa (radiant tube kudziyisa kudzikisa chikamu; RTF chikamu), chikamu chinotonhora nekukurumidza (chikamu cheJFC), uye chikamu chinotungamira (TDS chikamu). Iwo chaiwo lining structures ndeaya anotevera:
(1) The preheating chikamu:
Iyo pamusoro pechoto uye madziro echoto anotora iyo inoumbwa yevira mbiru yakarongedzerwa neCCEWOOL ceramic fiber modules uye ceramic fiber magumbeze. Iyo yakaderera-yemhepo lining inoshandisa layer yeCCEWOOL 1260 fiber magumbeze akamanikidzwa kusvika 25mm, nepo inopisa nzvimbo inoshandisa CCEWOOL zirconium-ine fiber yakapetwa mabhuroko. Iyo lining pazvikamu zvepamusoro-soro inotora jira reCCEWOOL 1260 fiber gumbeze, uye nzvimbo inopisa inoshandisa ceramic fiber modules.
Iyo pazasi pechoto inotora iyo yakaturikidzana inoumbwa lining yechiedza ivhu zvidhinha uye ceramic fiber modules; zvikamu zvakaderera-kupisa zvinotora maumbirwo akaumbwa ezvidhinha zvevhu rakareruka uye zirconium-ine ceramic fiber modules, nepo zvikamu zvepamusoro-soro zvinotora chimiro chakaumbwa chezvidhinha zvevhu uye ceramic fiber modules.
(2) Hapana oxidation yekudziya chikamu:
Pamusoro pechoto chinotora chimiro chakaumbwa checeramic fiber modules uye ceramic fiber magumbeze, uye iyo yekumashure lining inotora 1260 ceramic fiber magumbeze.
Izvo zvikamu zvakajairika zvemadziro echoto: a composite choto lining chimiro cheCCEFIRE lightweight high-alumina zvidhinha + CCEFIRE lightweight thermal insulation bricks (volume density 0.8kg/m3) + CCEWOOL 1260 ceramic fiber blankets + CCEWOOL calcium silicate boards.
Iwo anopisa emadziro echoto anotora chimiro chechoto chinosanganiswa cheCCEFIRE lightweight high alumina zvidhinha + CCEFIRE lightweight thermal insulation bricks (volume density 0.8kg/m3) + 1260 CCEWOOL ceramic fiber magumbeze + CCEWOOL calcium silicate board.
(3) Chikamu chekunyura:
Kumusoro kwechoto kunotora chimiro chakaumbwa chevira cheCCEWOOL ceramic fiberboard magumbeze.
