Kauj ruam 1: Visual & Format Inspection
| Tus chij liab | Yuav Nrhiav Dab Tsi |
|---|---|
| Cov fonts tsis sib haum lossis cov ntawv sib dhos | Cov ntawv sau tsis raug qhia txog kev kho lossis "txiav thiab muab tshuaj" kev tswj xyuas |
| Blurred mill logo lossis class society stamp | Cov ntawv pov thawj tseeb muaj qhov tseeb, siab - cov ntawv pov thawj daws teeb meem |
| Tsis muaj QA stamp lossis kos npe | Tsis muaj zeb zoo stamp=daim ntawv pov thawj tsis raug |
| Kev hloov pauv yam tsis muaj countersignature | Txhua qhov kev kho yuav tsum raug ntaus thiab pib; txwv tsis pub, tsis lees paub |
Kauj Ruam 2: Kub Tus lej Match (Txoj Cai Golden)
Yuav kuaj li cas:Tus naj npawb cua sov ntawm MTC yuav tsumraws nraim matchsteel stamp rau ntawm lub cev phaj.
Qhov chaw ntawm phaj stamp:Sab los yog kawg ntawm txhua lub phaj
Dab tsi los txheeb xyuas:Kub No. thiab Batch No. yuav tsum zoo ib yam -tsis muaj tus lej ploj, tsis muaj kev hloov pauv
| Scenario | Kev ua |
|---|---|
| Cov naj npawb cua sov sib phim | ✅ Ua ntej |
| Thaum tshav kub kub tsis muaj nyob rau ntawm phaj | ⚠️ Tsis lees txais tam sim |
| Thaum tshav kub kub tus naj npawb txawv ntawm MTC | ❌ Kev tsis lees paub tseem ceeb - hu rau tus muag khoom tam sim ntawd |
💡 Vim li cas qhov no tseem ceeb:Cov xov tooj cua sov yog qhov tshwj xeeb "DNA" ntawm pawg. Txhua qhov kev xeem tau ntawm MTC raug khi rau tus lej no. Yog hais tias lawv tsis phim, daim ntawv pov thawj belongs rau ib pawg sib txawv.
⚠️ Ceeb toom:Hlau stamps tuaj yeem raug faked. Qee cov neeg muag khoom siv cov ntawv hlau lossis cov tshuab cim npe siv cov lej cuav. Ib txwm hla- tshawb xyuas nrog MTC thiab txiav txim siab thib peb- pov thawj tog.
Kauj Ruam 3: Certificate Type & Class Society Pom Zoo
Yuav kuaj li cas:Tsis yog txhua tus MTCs sib npaug. Shipbuilding xav tau ib hom ntawv pov thawj tshwj xeeb.
EN 10204 Certificate Hom
| Hom | Kev piav qhia | Txaus siab rau Shipbuilding? |
|---|---|---|
| 2.2 | Factory test report, Basic info | ❌ Tsis muaj - tsis txaus |
| 3.1 | Mill{0}}tso tawm nrog cov txiaj ntsig kev xeem tiag tiag los ntawm pawg | ✅ Yog - tus qauv rau feem ntau marine daim hlau |
| 3.2 | Kev ywj pheej ua tim khawv los ntawm cov neeg soj ntsuam hauv chav kawm | ✅ ✅ Yuav tsum tau siv rau daim ntawv thov tseem ceeb (offshore, tub rog) |
Class Society Approval Checklist
| Lub ntsiab | Yuav Qhia Li Cas |
|---|---|
| Class Society logo | ABS, LR, BV, CCS, DNV - logo yuav tsum tau luam tawm kom meej |
| Pom zoo naj npawb | Works Approval No. los yog daim ntawv tso cai tus neeg soj ntsuam |
| Tus neeg soj ntsuam stamp | Sau ntawv los yog kos npe hauv hluav taws xob + stamp + hnub tim |
| Lub koom haum tsis ncaj ncees | ❌ Piv txwv li, LR stamp ntawm daim ntawv pov thawj CCS=tsis lees paub |
Kauj Ruam 4: Cov ntaub ntawv siv tau txheeb xyuas - Tshuaj & Mechanical Properties
Yuav kuaj li cas:Qhov ntsuas qhov tseeb yuav tsum poob rau hauv cov kev txwv tshwj xeeb - thiab yuav tsum tsis txhob saib "zoo meej heev."

Kauj Ruam 5: Kev Tshawb Fawb Digital (Txoj Kev Niaj Hnub No)
Cov txheej txheem pov thawj
| Txoj kev | Yuav siv li cas |
|---|---|
| QR code scan | Luam theej duab QR code ntawm MTC - yuav tsum txuas mus rau lub zeb qhov chaw pov thawj raug cai |
| Mill QA department | Hu rau lub zeb ncaj qha nrog daim ntawv pov thawj naj npawb, cov xov tooj cua sov, thiab cov ntaub ntawv batch |
| Blockchain platforms | Qee lub mills (piv txwv li, Baosteel, Shangang) teeb meem tamper - ntawv pov thawj cov ntawv pov thawj nrog cov lej QR cov lej thiab cov nyiaj siv hluav taws xob |
| CCS Customer Service System | Rau CCS- daim ntawv pov thawj, siv CCS online system los txheeb xyuas qhov xwm txheej ntawm daim ntawv pov thawj thiab rub tawm MTCs hluav taws xob |

leej twg xaiv peb?
Peb cog lus tias yuav muab cov ntaub ntawv pov thawj ntawm lub Hoobkas muaj tseeb thiab pov thawj los ntawm Tuam Tshoj Classification Society (CCS A steel) thiab cov ntawv pov thawj tshuaj xyuas cov khoom nrog rau cov khoom. Qhov no yog ib qho tseem ceeb heev uas yuav tsum tau rau lub shipyard warehouse txais txheej txheem.
Cov kev qhia tshwj xeeb (CCS A 6-40mm) muaj nyob rau hauv cov khoom txaus thiab tuaj yeem txiav rau txhua qhov ntev raws li cov neeg siv khoom xav tau. Qhov tshwj xeeb no pab cov chaw nres nkoj txo cov khoom pov tseg los ntawm cov khoom seem thiab txo cov nqi yuav khoom.
Raws li qhov loj ntawm qhov kev txiav txim thiab keeb kwm ntawm kev koom tes, peb tuaj yeem muab cov nqe lus them nqi sib tw los pab lub nkoj ua kom zoo dua nws cov nyiaj ntsuab.

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?
