Yuav tsum-Nyeem rauShipbuilding Steel PhajKev Yuav: Yuav Ua Li Cas Nyeem MTC (Mill Test Certificate)
Ntsiab lus: MTC txhais, cov ntaub ntawv pov thawj pov thawj, shipyard zoo tswj, faib pawg neeg pom zoo, steel phaj txais
Rau shipyard QC cov neeg ua haujlwm,Kev txheeb xyuas tias txhua pawg ntawm marine steel daim hlau sib phim nws MTC (Mill Test Certificate) yog thawj zaug thiab tseem ceeb tshaj plaws hauv kev ua kom lub phiaj xwm hla kev soj ntsuam hauv chav kawm.. Kev ua raws li MTC tsis yog pov thawj ntawm cov hlau zoo xwb; nws yog cov ntaub ntawv tseem ceeb uas tau tshuaj xyuas los ntawm cov neeg soj ntsuam kev faib tawm hauv zej zog.
Phau ntawv qhia no rhuav tshem cov ntsiab lus tseem ceeb ntawm MTC thiab muab ib qhoteb-npaj daim ntawv tshuaj xyuaslos pab koj txheeb xyuas cov ntawv pov thawj muaj teeb meem sai thiab zam qhov kev ncua sij hawm los ntawm cov ntaub ntawv teeb meem.
MTC yog dab tsi thiab vim li cas nws tseem ceeb?
MTC yog tusdaim ntawv pov thawj zoomuab los ntawm steel zeb, kaw:
Kev ruaj ntseg thiab kev lees paub yog qhov tseem ceeb
Tshuaj muaj pes tsawg leeg(txhais tau tias ua raws li cov cai hauv zej zog hauv chav kawm)
Toughness ntawm qhov kub thiab txias
Mechanical zog(tus nqi tiag tiag rau yield, tensile, elongation, cuam tshuam, thiab lwm yam)
Qhov sib txawv ntawm corrosion kuj
Cov ntaub ntawv traceability(cov xov tooj cua sov, batch tooj, phaj tooj)
Kev pom zoo(kev faib pawg neeg soj ntsuam daim ntawv pov thawj lossis tus lej pom zoo)

Ntawm -Kev Tshawb Xyuas Qhov Chaw: Peb-Cov Txheej Txheem QC
Kauj Ruam 1: Plaub-Point Document-rau-Plate Match
Thaum daim hlau tuaj txog, QC yuav tsum ua cov noplaub kuaj thaum lub sij hawm unloading:
| Tshawb xyuas | Kev ua | Pass Criteria |
|---|---|---|
| Kub naj npawb | Sib piv qhov Kub Tsis Tau ntawm MTC nrog rauhlau stampntawm txhua lub phaj (sab los yog kawg). | Muaj kev sib tw; tsis muaj omission los yog hloov. |
| Class Society Marking | Tshawb xyuas txhua lub phaj kom meejclass social stamp(eg, CCS, ABS, LR, DNV). | Stamp yog qhov tseeb thiab phim rau cov zej zog hauv chav kawm uas tau pom hauv MTC. |
| Qhov ntev | Random ntsuas thickness thiab dav (tsawg kawg 10% ntawm daim hlau, tsawg kawg 3 daim hlau). | Ntsuas qhov ntsuas nyob rau hauv MTC kam rau ua (ib txwm thickness kam rau ua: -0.3/+0.5mm). |
| Quantity & ID | Suav daim phiaj; txheeb xyuas qhov tshwj xeebphaj tooj(yog muaj) tawm tsam MTC. | Ntau qhov sib tw; phaj tooj sib haum nrog MTC daim ntawv teev npe. |
Kauj ruam 2: Cov ntaub ntawv muaj tseeb pov thawj
Puas yog cov khoom siv tshuaj thiab cov khoom muaj nqis nyob rau hauv specification?
Muab piv rau covcov kev cai hauv zej zoghauv koj qhov kev yuav khoom spec (piv txwv li, CCS Qib A: C Tsawg dua lossis sib npaug rau 0.21%, yield Ntau dua lossis sib npaug rau 235 MPa). Paub meej tias tag nrho cov nqi tiag tiag yogtsis yog qhov tsawg kawg nkaus lossis siab tshaj qhov siab tshaj plaws(qee lub ntsiab lus saum toj kawg nkaus yuav tsis cuam tshuam lub zog tab sis tuaj yeem cuam tshuam rau weldability).
Puas yog qhov kev ntsuam xyuas cuam tshuam tau raws li qhov xav tau?
Yog tias qhov project xav tau qis- qhov kub thiab txias (piv txwv li, CCS A xav tau 0℃longitudinal cuam tshuam loj dua lossis sib npaug rau 27J), xyuas kom meej tias MTC qhiacuam tshuam kev xeemthiab hais tias qhov nruab nrab ntawm peb tus qauv Ntau dua lossis sib npaug rau 27J, tsis muaj ib qho nqi qis dua 20J.
Kauj Ruam 3: Daim Ntawv Pov Thawj Ua tiav
Puas yog MTC yog thawj lossis daim ntawv pov thawj?
Feem ntau cov koom txoos xav tauoriginal hard copynrog cov khoom xa tuaj (lossis daim ntawv pov thawj hluav taws xob). Cov ntawv theej lossis tsis yog - ntawv pov thawj scan feem ntau tsis lees txais los ntawm cov kws tshawb fawb.
MTC puas muaj lub zeb zoo?
MTC siv tau yuav tsum muajmill's official QA stampthiab tus neeg kos npe lub npe.
| Hom teeb meem | Piv txwv | Risk Level | Pom zoo ua |
|---|---|---|---|
| Thaum tshav kub kub tsis sib haum | Thaum tshav kub kub tsis yog nyob rau hauv MTC txawv ntawm lub phaj stamp. | Tseem ceeb | Tsis lees paub. Tam sim ntawd hu rau tus neeg muag khoom; thov kom raug MTC txuam daim hlau. |
| Daim Ntawv Pov Thawj Tsis Muaj | MTC muaj mill stamp nkaus xwb, tsis muaj pawg neeg soj ntsuam xyuas kos npe / hluav taws xob stamp. | Tseem ceeb | Tsis lees paub. Cov ntawv pov thawj zoo li no yuav tsis raug kuaj xyuas hauv chav kawm. Thov kom pom zoo daim ntawv pov thawj. |
| Mechanical Properties Tawm ntawm Spec | Tawm los yog elongation hauv qab yam tsawg kawg nkaus yuav tsum tau. | Tseem ceeb | Tsis lees paub. Thov qhov thib peb- rov sim dua. Yog tias tseem tsis -ua raws, rov qab cov khoom. |
| Chemical Composition Tawm ntawm Spec | P lossis S cov ntsiab lus siab dua cov kev txwv hauv zej zog. | Nruab nrab | Nyob ntawm qhov hnyav: yog tias tsis zoo, sab laj nrog tus kws tshawb fawb txog qhov ua tau txais; yog hais meej tawm ntawm spec, tsis lees paub. |

FAQ
01.Lub npe ntawm daim phiaj nkoj txiav txim li cas? Piv txwv li, CCS A txhais li cas?
A: Qhia tau hais tias lub zog theem yog lub zog dav dav. Lub zog dav dav hlau daim hlau tau muab faib ua plaub qib: A, B, D, thiab E. Qhov sib txawv tseem ceeb nyob rau hauv qhov ntsuas kub rau qhov cuam tshuam rau qhov hnyav (qib A ntawm 0 degree, qib B ntawm 20 degree, qib D ntawm -20 degree, thiab qib E ntawm -40 degree).
02.Thaum yuav daim phiaj nkoj, koj tuaj yeem muab cov ntaub ntawv dab tsi?
Traceability: Lub cub tawg tooj thiab batch naj npawb ntawm daim ntawv pov thawj yuav tsum ua raws li cov cim lub cev ntawm cov hlau phaj.
Cov ntaub ntawv: Nws yuav tsum suav nrog cov ntaub ntawv ntsuas tseeb xws li tshuaj lom neeg muaj pes tsawg leeg, cov khoom siv kho tshuab (yield, tensile zog, cuam tshuam tus nqi), thiab lwm yam.
03.Qhov kev txiav txim yam tsawg kawg nkaus yog dab tsi?
04.Koj puas tuaj yeem muab kev pabcuam txiav thiab ua haujlwm?
