1. Kev Kho Cua Sov Kev Siv Tau
Lr yuav tsumCov ntaub ntawv ntxaws ntxaws thiab kev simRau Q & T cov hlau ua kom muaj cov khoom muaj xwm txheej.
Q & T:
Cov Ntaub Ntawv Kho Mob Thaum Tshav Kub Kub Tshwj Xeeb.
Hardness Uniformity Checks.
TMCP Yooj Yim:
TMCP cia siab rauTSHUAJ RollING + CUA TXIAS, nrog tsawg dua post-rolling state.
Lr lees txaiszeb-tsim tshuaj TMCPYog tsis muaj kev siv tau.
Kev Kawm Txog:
Ib qho Kauslim Mill's Q & T FH40 tau tso tseg los ntawm LR vimtsis sib haum npau taws kub(Ib Lr Cov Cai Pt.3, Ch.2).
HloovQ & T Daim Ntawv Pov Thawj Ntxiv2-3 lub lis piammus rau cov sij hawm thiab TMCP.
2. Cov Cuab Yeej Cuab Yeej Cuab Yeej Cuab Yeej
Q & T cov hlau txuas ntxivNtau tshaj xeem xeemkom soj ntsuam lub zog thiab tawv.
Tensile & Kev Ntsuas Kev Cuam Tshuam:
Q&T: Triple qhov kev sim zaus zaus(ib txog 50 tons vs. Tmcp's 100 tons).
Sub-Nto Kuaj mandatory for thick Q&T plates (>50 hli).
TMCP Simplua Lawm:
TMCP cov qib (piv txwv li, lr Eh36) yuav tsum tauKev kuaj qib degtshwj tsis yog teev.
Cov Qauv Tseem Ceeb:
Lr yuam kev-60℃charpy kev simRau Q & T FH40 hauv kev siv hauv polar (vs . -40℃rau TMCP EH36).
Cov ntaub ntawv taw tes: Q & T FH550 xav tauNtau dua los yog sib npaug rau 100j ntawm -40 degree, thaum Tmcp Fh550 yuav txaisNtau dua los yog sib npaug rau 80j.
3. Cov Txheej Txheem Vuam Cov Khoom Siv
Q & T Steels thovstricter vuam tswjTxhawm rau zam kom tsis txhob muaj taub hau me me lossis tawg.
Preheat & Interpass Kub:
Q&T: Siab dua preheat (150-200 degree)kom tiv thaiv kev sib tsoo martensite.
TMCP: Feem ntau100-150 degreeVim tias finer grade qauv.
Cov kev txwv tsis muaj txiaj ntsig:
Q & T Welds xav tauNi-based electrodesrau cov tawv sib xyaw.
TMCP tso caiTxheem qes-h Electrodes.
Lr txoj cai siv:
WPS rau Q & Tyuav tsum muajPWHT (POST-Weld Kev Kho Cua Sov)Cov phiaj xwm.
Tus yam ntxwv: European Rearyard's Q & T FH40 Welds ua tsis tiav LR tshuaj vim yogtsis txaus preheat.
4. Tsis Yog-kev sim ua txhaum (NDT) Rigor
Lr tswj hwmTxhim Kho NDTRau Q & T Steels vim muaj kev pheej hmoo txaus ntshai.
Ut / mt cov kev xav tau:
Q&T: 100% ut + mt for all thicknesses >15 hli.
TMCP:UT for >20mm, cov chaw MT tshwj tsis yog qhov tseem ceeb.
Phased-array ut (Paut):
Yuav tsum ua Q & TTaub Qab Weldnyob rau hauv Hull girders.
Kev Tiv Thaiv Kev Mob:
Q&T: Xoom nrib pleb tso cai; TMCP tso cai tsawg dua los yog sib npaug rau 4 hli suav nrog.
Nqi Them Nqi: Q & T NDT ntxiv20–30%mus rau Fabrication nqi thiab TMCP.
**5. Cov nqi pov thawj thiab cov sij hawm coj ua
Q&T's complex ntau lawmtxhais cov nqi siab dua thiab ntev dua LR kev pom zoo mus los mus.
Mill Ntawv pov thawj:
Q & T Mills xav tauLR kev kuaj xyuas txhua xyoontawm cov tshuab hluav taws xob thiab quenching cov tshuab.
TMCP mills yauv musbiennial auditsntawm dov / txias kab.
Kev Ntsuas Cov Nqis:
Q & T cov ntawv yuav tsum tauntxiv charpy, khoov, thiab kev ntsuam xyuas hardness.
Kev Ua Lag Luam Tiag:
80% ntawm lr-ntawv pov thawj FH40Siv TMCP vim muaj tus nqi qis dua thiab kev pom zoo sai.
Tsuas yog: Q & T Dominatesthick plates (>80mm)qhov twg tmcp struggles nrog kev sib dhos.
