Hlau sib xyaw panels tau siv dav hauv ntau yam lag luam xws li tshuaj lom neeg, roj av, petrochemical, kev lag luam teeb pom kev zoo, khoom noj khoom haus thiab tshuaj rau kev tiv thaiv corrosion thiab khoom siv tu khoom. Hauv kev xyaum, nws tau raug pov thawj tias cov hlau sib xyaw ua ke yog cov khoom siv zoo tshaj plaws los tiv thaiv corrosion. Muaj peb txoj kev tsim khoom rau cov hlau sib xyaw phaj - txoj kev tawg, txoj kev dov, thiab txoj kev tawg tawg. Los ntawm kev pom ntawm lub zog shear, cov phaj sib xyaw ua los ntawm txoj kev tawg muaj qhov siab tshaj plaws shear zog, ncav cuag 290MPa (tus qauv yog 210MPa).
Tam sim no, cov hlau tsis muaj steel, titanium, tooj liab, txhuas, npib tsib xee, E, hlau (tshwj xeeb tshaj yog tiv taus ntsev brine corrosion) thiab carbon steel, low-alloy steel tuaj yeem tsim hauv tsev. Lub rooj tsavxwm dav tuaj yeem ncav cuag 1.7m, thiab lub rooj tsavxwm ntev tuaj yeem ncav cuag 8m (qee lub rooj sib xyaw tuaj yeem ncav cuag 1.9m hauv qhov dav). Kev tsim cov vaj huam sib luag sib xyaw tuaj yeem txuag tau zoo heev ntawm kev siv cov hlau muaj txiaj ntsig thiab txo cov khoom siv peev hauv engineering, ua lub luag haujlwm zoo hauv kev txuag cov peev txheej thiab txo cov nqi tsim kho engineering rau lub teb chaws thiab cov tog neeg tsim kho. 2. Ntau qhov teeb meem yuav tsum tau muab sau tseg hauv daim ntawv thov ntawm cov hlau sib xyaw phaj.
Muaj ntau yam teeb meem yuav tsum tau muab sau tseg nyob rau hauv daim ntawv thov ntawm hlau composite daim hlau
(1) Kev tsim thiab txiav
Kev tsim cov hlau sib xyaw phaj yuav tsum tau nqa tawm los ntawm kev siv cov txheej txheem txias kom ntau li ntau tau, uas tuaj yeem zam qhov txo qis ntawm cov khoom siv sib xyaw, tshwj xeeb tshaj yog cov hlau tsis muaj hlau sib xyaw. Tsis muaj teeb meem nrog cov hlau sib xyaw phaj thaum txias ua haujlwm los yob cov duab yooj yim, tab sis thaum tig thiab nias lub taub hau, yuav tsum tau them nyiaj rau qhov txias ua hauj lwm hardening ntawm ferritic stainless hlau puas phaj thaum lub sij hawm nias txheej txheem. Piv txwv li, 0Cr13A1+16MnR cov phaj sib xyaw. Thaum lub sij hawm nias, thaum lub hauv qab ntawm lub taub hau yog nias, nws yuav raug cua txias annealing kev kho mob ntawm 830+10 degree rau 15 feeb (lub cub tawg kub tsawg dua los yog sib npaug zos rau 400 degree, kub nce ntawm 150 degree / h ), thiab tom qab ntawd cov npoo ntawm lub taub hau yog spun. Txwv tsis pub, lub taub hau yog qhov ua rau tawg tawg lossis tawg thaum lub sij hawm ntug spinning. Nws yog qhov zoo tshaj plaws los siv lub tshuab shearing rau kev txiav. Yog hais tias lub phaj thickness yog tuab, plasma txiav yuav siv tau, los yog cov roj txiav los yog oxygen pab txiav yuav siv tau. Thaum txiav, yuav tsum tau them nyiaj rau kev txiav los ntawm lub hauv paus nto. Pib txiav. Kev txiav ntug ntawm cov ntawv txiav kub sib xyaw yuav tsum tau ua tib zoo ntxuav ua ntej vuam.
(2) Cua sov
When the thickness of the composite board base layer is large (8>2.5% D;, D yog lub puab txoj kab uas hla ntawm lub voj voog) los yog thaum kub nias los yog kev kho cua sov yuav tsum tau rau lub taub hau, cov cua nyob rau hauv lub cub tawg yuav tsum nruj me ntsis tswj. Nws yog qhov zoo tshaj plaws los siv txoj kev siv hluav taws xob cua sov, xws li siv cov thee, cov pa roj carbon monoxide lossis cov roj cua kub cua sov. Qhov qis dua cov sulfur cov ntsiab lus hauv qhov cub, qhov zoo dua. Rau qee cov ntaub ntawv uas yuav tsum tau tshwj xeeb rau cov ntsiab lus sulfur, nws yuav tsum tau qhia rau ntawm daim duab. Ntawm qhov chaw ntawm kev ua haujlwm ntawm cov khoom siv sib xyaw ua ke, lub sijhawm rwb thaiv tsev ntawm cov khoom siv hauv qhov cub yuav tsum tsis txhob ntev dhau. Raws li kev paub dhau los ntawm lub Hoobkas tsim khoom, lub sijhawm rwb thaiv tsev yuav tsum tsis pub tshaj 25 feeb thiab cua sov zaus yuav tsum tsis pub tshaj 3 zaug. (3) Cov txheej txheem vuam rau vuam hlau sib xyaw phaj yog: thawj zaug vuam txheej txheej, tom qab ntawd vuam txheej txheej hloov, thiab thaum kawg vuam txheej txheej. Cov txheej txheem hloov pauv yog txheej txheem tseem ceeb thaum vuam, txwv tsis pub cov kab nrib pleb tuaj yeem tshwm sim tom qab vuam. Tsis tas li ntawd, thaum welding hloov txheej txheej thiab cladding, yuav tsum tau them nyiaj mloog mus rau kev siv me me-inch welding rods, me me specifications, ncaj welds, thiab multi pass welding. Lwm cov txheej txheem vuam tuaj yeem ua tiav raws li cov chaw tsim khoom kev paub lossis cov txheej txheem vuam muab pub dawb los ntawm cov chaw tsim khoom phaj sib xyaw. Thaum lub sij hawm vuam txheej txheem, yuav tsum tau them nyiaj rau tu txhua txheej ntawm vuam seam thiab sai tshem tawm impurities xws li oxide daim tawv nqaij kom ntseeg tau tias vuam zoo. Hlau sib xyaw panels tau siv dav thiab yog cov khoom siv zoo tshaj plaws engineering uas txuag cov peev txheej thiab kev nqis peev. Ntev npaum li cov txheej txheem ua tau them nyiaj rau hauv daim ntawv thov, thiab cov txheej txheem kev ua haujlwm thiab cov ntaub ntawv muab los ntawm cov chaw tsim khoom vaj huam sib luag tau hais txog, cov txiaj ntsig zoo tuaj yeem tau txais.
