X70 kab yeeb

X70 kab yeeb nkab ua rau nrog thoob ntiaj teb thiab cov qauv hauv tebchaws xws li API spec 5L thiab GB / T9711. Nws yog qhov qis-}}}}} tech, siab}}} {8} {8} {8} {8} {8} {8} {8} {8} {8} {8} {8} {8} {8} {8} {8} {8} {8} {8} {8} {8} {8} {8} {8} {8} {8} {8} {8} {8} {8} {8} {8} {8} {8} {8} {8} {8} {8} {8} {8} {8} {8} {8} {8} {8} {8} {8} {8} {8} {8} {8}. Cov yeeb nkab steel feem ntau yog siv nyob rau hauv cov roj thiab roj kev lag luam rau ntev} kev thauj mus los deb ntawm xov xwm xws li oxygen, dej, thiab roj. Peb X70 Kab Yeeb muaj cov txiaj ntsig zoo xws li muaj zog muaj zog, thiab oxidation zoo heev.

Shaanxi Dongyujia Hlau thiab Steel Co., Ltd. tshwj xeeb hauv kev tsim cov kav hlau ntau thiab cov qib kev cai hlau thiab ntau thiab tsawg. Yog tias koj xav tau cov khoom no, thov koj xav tiv tauj peb cov kev pabcuam kev tshaj lij!

 

 

1.qhemical muaj pes tsawg

Tsawg - Tus Qauv Carbon Tsim:C Tsawg dua los yog sib npaug rau 0.12% -0.16%, cov nqi roj carbon ntau dua (CEV) tsawg dua lossis sib npaug rau 0.43

Microalloying ntsiab:Nb (0.03-0.08%), v (0.01-0.04%), thiab ti (0.00-0.024%) rau cov khoom siv qoob loo lis

Kev Kho Kom huv:S Tsawg dua los yog sib npaug rau 0.005%, p tsawg dua lossis sib npaug rau 0.010%, zoo heev tiv taus rau hydrogen- qhov ua rau tawg (HIC)

 

2.Mechanical Khoom

Paib lub zog:Ntau dua los yog sib npaug rau 485 mpa

Lub zog tensile:Ntau dua los yog sib npaug rau 570 MPa, tawm suab tsawg dua lossis sib npaug rau 0.93

Tsawg - kub ceev:-20℃cuam tshuam lub zog loj dua los yog sib npaug rau 120 J (av siv) lossis ntau dua lossis sib npaug nrog 190 J (Nce Hiav Txwv Qaum Teb)

Elongation:Ntau dua los yog sib npaug rau 18% -28%

 

 

1.Forming thev naus laus zis

Longitudinal seam welded yeeb nkab (lsaw):Siv lub jcoe / uoe cov txheej txheem, siab - zaus vuam lossis submerged arc vuam ntawm lub longitudinal seam.

Muab kauv welded yeeb nkab (HFW):Chev Taub Qab Ua Ncauj Vuam raws li los ntawm high- zaus induction induction induction inductional kav.

Seamless Yeeb:Kub -} rolled lossis txias - Kos, haum rau high- qhov kev siv siab.

 

2.key cov txheej txheem

Kev tswj dov thiab txias (TMCP):FINISHING kub yog qis dua ntawm AR3 hloov pauv, nrog tus nqi txias ntawm 8-15℃/ s.

Kev Kho Cua Sov:X70Q cov qib yuav tsum tau quenching thiab tempering kom txhim kho qis qis- kub nruj.

Kev nthuav dav / Kev Kuaj Hydraulic:Tshem tawm cov kev ntxhov siab tseem ceeb, ua kom muaj kev ntxhov siab ntau dua lossis sib npaug nrog 0.6% ntawm txoj yeeb nkab taub.

 

3.Qhov kev soj ntsuam

Nondestructive Testing:Phased array ultrasonic kuaj (Paut) Ntsuas Weld tsis xws luag, nrog 30% siab dua rhiab dua li cov pa.

Tag nrho - nplai kuaj:Suav nrog tensile, khoov, thiab cuam tshuam kev cuam tshuam.

 

4.applications

 Loj strain tiv taus tsim yog siv rau ntev {}} deb} deb ntawm cov xov tooj cua / av qeeg / av qeeg thiab lwm thaj chaw tshwj xeeb
