NK Gr.A Shipbuilding Steel Phaj

Mechanical Property Testing
Kev Ntsuas Tensile: Cov qauv hlau phaj tau ncab ntawm lub tshuab ntsuas tensile kom txog thaum lawv tawg kom tau txais cov ntaub ntawv xws li lub zog tawm los, lub zog tensile, thiab elongation. Rau NK Gr.B Shipbuilding Steel Phaj, qhov tsawg kawg nkaus lub zog yuav tsum yog 235MPa, lub zog tensile yuav tsum nyob nruab nrab ntawm 400 - 520MPa, thiab qhov tsawg kawg nkaus elongation yuav tsum yog 22%. Cov ntaub ntawv no qhia txog kev ua tau zoo ntawm cov phaj steel thaum raug lub zog tensile. Yog tias lub zog tawm los tsis txaus, cov phaj hlau tuaj yeem deform ntxov thaum muaj zog; Qhov qis elongation qhia tias tsis zoo toughness ntawm steel phaj.

Impact Testing: Charpy V - notch impact test feem ntau siv. Cov qauv nrog V - notch yog muab tso rau ntawm kev txhawb nqa ntawm lub tshuab kuaj qhov cuam tshuam, thiab cov qauv raug cuam tshuam nrog lub pendulum. Lub zog siv los rhuav tshem cov qauv raug kaw los ntsuas qhov toughness thiab cuam tshuam tsis kam ntawm steel phaj. Nyob rau hauv ib puag ncig marine, ships thiab offshore structures raug rau ntau yam kev cuam tshuam xws li nthwv dej slaps thiab nkoj sib tsoo. Kev cuam tshuam zoo tuaj yeem tiv thaiv cov phaj hlau los ntawm kev tawg tawg hauv cov xwm txheej no.

Kev kuaj tsis muaj kev puas tsuaj
Ultrasonic Testing (UT): High - zaus ultrasonic tsis emitted los ntawm ultrasonic flaw detector propagate nyob rau hauv lub steel phaj. Thaum ntsib qhov tsis xws luag xws li pores, slag inclusions, thiab cov kab nrib pleb, ultrasonic tsis yuav tsim kev xav, refraction thiab lwm yam tshwm sim. Los ntawm kev txheeb xyuas cov yam ntxwv ntawm lub teeb liab ntawm qhov cuam tshuam tsis zoo, qhov chaw, qhov loj, thiab cov duab ntawm qhov tsis xws luag tuaj yeem txiav txim siab. Qhov no yog qhov zoo heev rau kev kuaj pom qhov sib sib zog nqus-sab hauv qhov tsis xws luag ntawm steel phaj. Piv txwv li, ua ntej steel phaj siv los tsim cov qauv tseem ceeb ntawm cov nkoj (xws li lub nkoj hauv qab), UT kev sim tuaj yeem ua kom nws cov khoom zoo.

Sib Nqus Particle Testing (MT): Rau ferromagnetic NK Gr.B Shipbuilding Steel Phaj, yog tias muaj cov kab nrib pleb thiab lwm yam tsis xws luag ntawm qhov chaw los yog nyob ze - nto, tom qab ib qho chaw sib nqus yog siv rau saum npoo ntawm cov hlau phaj thiab cov hlau nplaum sib nqus. sprinkled, cov kab hlau nplaum ntawm lub zog ntawm qhov tsis xws luag yuav distorted thiab cov hlau nplaum yuav sib sau ua ke ntawm qhov tsis xws luag, yog li qhia qhov chaw thiab cov duab ntawm qhov tsis xws luag. Txoj kev no feem ntau yog siv los txheeb xyuas qhov chaw thiab nyob ze ntawm qhov chaw ntawm cov hlau phaj, xws li cov kab nrib pleb me me nyob ib ncig ntawm qhov chaw welded.

 

 

 

Thickness - Directional Performance Test (Z - directional Performance Test)
Thaum lub phaj steel raug rau lub zog tensile loj nyob rau hauv thickness kev taw qhia, xws li nyob rau hauv lub tuab - phaj qauv ntawm loj - scale ships, Z - directional kev xeem yuav tsum tau. Qhov kev tiv thaiv rau lamellar tearing kev ua tau zoo ntawm cov phaj hlau nyob rau hauv thickness kev taw qhia (Z - kev taw qhia) yog soj ntsuam los ntawm tensile xeem. Feem ntau cov kev ua tau zoo sib txawv xws li Z15, Z25, thiab Z35. Qhov no yog vim hais tias nyob rau hauv offshore engineering qauv, qee qhov kev sib txuas yuav raug rau tensile rog perpendicular rau saum npoo ntawm steel phaj. Yog tias Z - kev taw qhia kev ua haujlwm tsis txaus, cov phaj hlau yog qhov ua rau lamellar tearing.
