Loj txoj kab uas hla kauv steel yeeb nkab chaw tsim tshuaj paus
ib.Thaum lub sij hawm tsim cov txheej txheem, cov hlau phaj yog deformed tusyees, cov residual kev nyuaj siab yog me me, thiab nto tsis khawb. Cov txheej txheem kauv steel yeeb nkab muaj qhov yooj yim dua nyob rau hauv qhov loj thiab qhov tshwj xeeb ntawm txoj kab uas hla thiab phab ntsa tuab, tshwj xeeb tshaj yog nyob rau hauv kev tsim cov qib siab tuab phab ntsa yeeb nkab, tshwj xeeb tshaj yog me me thiab nruab nrab tuab tuab phab ntsa yeeb nkab, uas muaj qhov zoo sib xws ntawm lwm cov txheej txheem, thiab tuaj yeem ua tau raws li qhov xav tau ntau ntawm cov neeg siv hauv cov lus qhia ntawm kauv steel yeeb nkab.
b. Cov txheej txheem ob-sided submerged arc vuam txheej txheem tuaj yeem paub vuam ntawm txoj haujlwm zoo tshaj plaws, uas tsis yooj yim kom muaj qhov tsis xws luag xws li misalignment, vuam sib txawv thiab tsis tiav qhov nkag, thiab nws yooj yim los tswj cov vuam zoo.
c. 100% kev soj ntsuam zoo yog nqa tawm ntawm cov yeeb nkab steel, kom tag nrho cov txheej txheem ntawm cov yeeb nkab steel yog nyob rau hauv kev tshawb nrhiav thiab kev saib xyuas zoo, thiab cov khoom zoo tau lav zoo.
d. Tag nrho cov khoom siv ntawm tag nrho cov kab ntau lawm muaj kev ua haujlwm ntawm kev sib txuas nrog cov ntaub ntawv hauv computer kom paub txog cov ntaub ntawv xa mus rau lub sijhawm tiag tiag, thiab cov kev tsis sib xws hauv cov txheej txheem tsim khoom raug saib xyuas los ntawm lub hauv paus tswj chav.
Lub kauv steel yeeb nkab yuav tsum raug kuaj xyuas cov cuab yeej cuab tam, kev sim flattening thiab flaring xeem ua ntej tawm hauv lub Hoobkas, thiab yuav tsum ua raws li cov cai teev tseg hauv tus qauv. Txoj kev tshuaj xyuas zoo ntawm cov yeeb nkab ncaj seam steel yog raws li hauv qab no:
1.Judging los ntawm qhov chaw, uas yog, nyob rau hauv lub tsos tshuaj ntsuam. Kev soj ntsuam zoo ntawm cov pob qij txha welded yog ib qho yooj yim thiab dav siv tshuaj xyuas txoj kev. Nws yog cov ntsiab lus tseem ceeb ntawm kev tshuaj xyuas cov khoom tiav. Nws yog tsuas yog nrhiav qhov tsis xws luag ntawm qhov chaw weld thiab qhov sib txawv ntawm qhov sib txawv. Feem ntau, kev tshuaj xyuas yog ua los ntawm kev soj ntsuam kev pom nrog kev pab los ntawm cov qauv qauv, ntsuas ntsuas, lub iav tsom iav thiab lwm yam cuab yeej. Yog tias muaj qhov tsis xws luag ntawm qhov chaw weld, tej zaum yuav muaj qhov tsis xws hauv qhov vuam.
2.Kev ntsuas lub cev: txoj kev kuaj lub cev yog ib txoj hauv kev ntsuas lossis ntsuas los ntawm kev siv qee qhov tshwm sim ntawm lub cev. Kev ntsuam xyuas tsis muaj kev puas tsuaj feem ntau yog siv los tshuaj xyuas qhov tsis xws ntawm cov khoom lossis cov khoom ua haujlwm. NDT suav nrog ultrasonic qhov tsis pom kev, kuaj pom qhov tsis txaus ntseeg, kuaj pom qhov tsis txaus ntseeg, kuaj pom qhov tsis zoo, thiab lwm yam.
3.Kev ntsuas lub zog ntawm cov hlab ntsha siab: ntxiv rau qhov kev ntsuas nruj, kev ntsuas lub zog yuav tsum tau ua rau cov hlab ntsha siab. Muaj ob hom kev sim: hydrostatic test thiab pneumatic test. Lawv tuaj yeem kuaj qhov vuam nruj ntawm cov hlab ntsha thiab cov kav dej ua haujlwm hauv siab. Pneumatic xeem yog rhiab heev thiab sai dua li hydraulic test. Nyob rau tib lub sijhawm, cov khoom kuaj tsis tas yuav tsum tau kho cov kua dej, uas yog tshwj xeeb tshaj yog tsim rau cov khoom uas muaj cov dej tsis zoo. Tab sis qhov kev ntsuam xyuas yog qhov txaus ntshai tshaj qhov kev sim hydrostatic. Thaum lub sij hawm xeem, cov kev ntsuas kev ruaj ntseg yuav tsum tau soj ntsuam kom tsis txhob muaj xwm txheej thaum lub sij hawm xeem.
4.Compactness test: rau welded cov hlab ntsha khaws cov kua los yog roj, qhov tsis yog compactness ntawm welds, xws li nkag mus rau cov kab nrib pleb, pores, slag inclusion, incomplete penetration thiab xoob qauv, yuav nrhiav tau los ntawm compactness test. Cov txheej txheem kev ntsuas compactness muaj xws li kuaj kerosene, ntsuas dej nqa, ntsuas dej cuam tshuam, thiab lwm yam.
5.Rau kev ntsuam xyuas hydrostatic, txhua cov yeeb nkab steel yuav tsum raug kuaj hydrostatic yam tsis muaj qhov to. Kev ntsuas siab yuav tsum raug xam raws li P = 2st / D, qhov twg s - Test Stress MPa ntawm hydrostatic test, thiab qhov kev ntsuam xyuas kev nyuaj siab ntawm hydrostatic test yuav tsum raug xaiv raws li 60% ntawm qhov tsawg kawg nkaus tus nqi tau teev tseg hauv cov qauv siv steel siv (Q235). yog 235mpa). Lub sij hawm stabilization siab: D. cov kauv vuam ntawm cov yeeb nkab steel rau cov kua xa tawm yuav tsum raug kuaj xyuas X-ray lossis ultrasonic (20%).
Raws li kev soj ntsuam zoo ntawm kauv steel yeeb nkab, kauv steel yeeb nkab feem ntau muab faib ua peb pawg: cov khoom tsim nyog, cov khoom kho thiab cov khoom pov tseg. Cov khoom tsim nyog xa mus rau kauv steel kav uas nws zoo li zoo thiab sab hauv zoo ua tau raws li cov qauv tsim nyog lossis cov txheej txheem rau kev lees txais; Kev kho cov khoom xa mus rau cov kav hlau kav uas nws qhov zoo thiab qhov zoo ntawm lub cev tsis ua raws li cov qauv thiab kev lees paub, tab sis raug tso cai kho, thiab tuaj yeem ua tau raws li cov qauv thiab kev lees paub tom qab kho; Cov khib nyiab yog hais txog cov kav hlau kav uas muaj qhov zoo thiab qhov zoo ntawm sab hauv tsis tsim nyog, uas tsis raug tso cai los kho lossis tseem ua tsis tau raws li cov qauv thiab kev lees paub tom qab kho.
Cov khoom pov tseg tau muab faib ua cov khib nyiab sab hauv thiab cov khib nyiab sab nraud. Cov khib nyiab sab hauv yog hais txog cov khib nyiab kauv steel yeeb nkab uas pom nyob rau hauv qhov chaw tsim khoom lossis chaw tsim khoom; Cov khib nyiab sab nraud yog hais txog cov khoom pov tseg tom qab xa cov kav hlau kav, uas feem ntau raug rau hauv cov txheej txheem machining, kev kho cua sov lossis siv, thiab nws cov kev lag luam poob ntau dua li ntawm cov khib nyiab sab hauv. Txhawm rau txo cov khoom pov tseg sab nraud, cov kav hlau kav hlau uas tsim los rau hauv cov khoom siv yuav tsum tau ua piv txwv rau kev sim kev kho cua sov thiab kev ua haujlwm ntxhib ua ntej tawm hauv lub Hoobkas, thiab qhov muaj peev xwm muab kauv steel yeeb nkab tsis xws luag yuav tsum pom nyob rau hauv cov kauv steel yeeb nkab cog kom deb li deb tau, yog li raws li kev ntsuas tsim nyog kho kom sai li sai tau.
1) Cov me me thiab nruab nrab-qhov loj me steel, hlau pas nrig, qhov cuab lub zog, qhov nruab nrab txoj kab uas hla steel yeeb nkab, steel hlau thiab steel hlau hlua tuaj yeem khaws cia rau hauv lub qhov cua zoo, tab sis lawv yuav tsum tau them thiab padded.
2) Qee cov hlau me me, steel ntawv, steel sawb, silicon steel ntawv, me-inch lossis nyias-phab ntsa steel yeeb nkab, ntau yam txias-kuav los tiag thiab txias kos cov hlau thiab cov khoom hlau nrog tus nqi siab thiab yooj yim corrosion tuaj yeem khaws cia rau hauv lub warehouse.
3)Lub tsev kawm ntawv lossis lub tsev khaws khoom khaws cia cov khoom siv steel yeeb nkab yuav tsum nyob hauv qhov chaw huv si thiab tsis muaj kev cuam tshuam, nyob deb ntawm cov chaw tsim khoom thiab cov mines uas tsim cov pa phem lossis plua plav. Cov nroj tsuag thiab tag nrho cov sundries yuav tsum tau muab tshem tawm ntawm qhov chaw kom cov hlau huv si.
4) Loj seem steel, rail, steel phaj, loj-inch steel yeeb nkab, forging, thiab lwm yam tuaj yeem muab tso rau hauv qhov qhib cua.
5)Nws tsis raug tso cai rau pawg nrog cov kua qaub, alkali, ntsev, cement thiab lwm yam ntaub ntawv uas muaj corrosive rau hlau hauv lub tsev rau khoom. Ntau hom hlau yuav tsum tau muab sib cais los tiv thaiv kev tsis sib haum xeeb thiab tiv thaiv corrosion.
6)Lub tsev khaws khoom yuav tsum raug xaiv raws li thaj chaw. Feem ntau, nws siv lub tsev khaws khoom kaw zoo tib yam, uas yog, lub tsev khaws khoom nrog lub ru tsev, qhov rooj kaw, kaw qhov rooj thiab qhov rais thiab cov khoom siv cua.
7) Lub tsev khaws khoom yuav tsum tau tso cua nyob rau hnub ci hnub ci, kaw rau hnub los nag kom tsis txhob ya raws, thiab ib txwm tswj kom muaj qhov chaw cia khoom tsim nyog.
