GNEE ASTM A517 Siab-Lub zog steel phaj paub txog kev xa khoom txawv teb chaws

Tsis ntev los no, lub ASTM A517 / A517M siab - lub zog siab lub nkoj steel phajsuas tsim los ntawm GNEE STEEL tau raug xa los ntawm Shanghai Chaw nres nkoj mus rau Australia, qhov chaw lawv yuav raug siv los tsim lub plhaub sab nrauv ntawm cov khoom loj - nplai crushing ntawm lub tuam txhab mining.

Thaum lub sijhawm nug thawj zaug, Australian cov neeg siv khoom tau hais meej meej txog lawv qhov kev thov: "Cov khoom siv yuav tsum tau tiv taus siab -ntau zaus cuam tshuam, yog li cov ntawv hlau yuav tsum muaj lub zog siab thiab hnav tsis kam." Nyob rau hauv teb rau tus qauv tus yam ntxwv ntawm ASTM A517 / A517M (yield tsawg kawg nkaus lub zog ntawm ntau tshaj los yog sib npaug zos rau 690MPa, tensile zog ntawm 795-930MPa, xa nyob rau hauv quenched + tempered mob, thiab haum rau siab -lub zog siab customized hlab ntsha thiab txais yuav ib tug structural kev daws teeb meem ntawm GNEE cov khoom), Kev tsim qauv tsim los txhim kho lub zog, siv kev tswj cov dov thiab tswj cov tshuab cua txias kom ntseeg tau tias kev ua tau zoo ntawm cov hlau phaj nyob rau hauv cov kev taw qhia tuab, thiab ib txhij muab kev txhawb nqa cov txheej txheem vuam txheej txheem.

Thaum lub sijhawm sib txuas lus, tus neeg siv khoom tau hais tias "cov ntawv hlau yuav tsum ua raws li cov kev cai ntawm Australian AS 1548 tus qauv". GNEE tau koom tes tam sim ntawd nrog rau thib peb - lub koom haum kuaj xyuas tog (Bureau Veritas, BV) los ua kev tshuaj xyuas raws li ob tus qauv. Daim ntawv tshaj tawm kev sim zaum kawg tau pom tias qhov cuam tshuam lub zog (Ntau dua lossis sib npaug ntawm 40J ntawm -40 degree) thiab hardness (HB220-260) ntawm cov hlau phaj tag nrho ua tau raws li qhov yuav tsum tau ua. Tom qab tsim cov thawj batch ntawm 120 tons ntawm steel daim hlau ( specifications: 16-30mm × 2000-3200mm × 9000mm) tiav, cov neeg muas zaub xa engineers mus rau lub Hoobkas rau kev txais. Tom qab ntawm qhov chaw random sampling thiab kuaj, cov engineers tau hais tias: "Qhov zoo ntawm GNEE cov hlau phaj siab tau mus txog qib siab thoob ntiaj teb, thiab peb yuav muab qhov tseem ceeb rau kev koom tes hauv cov haujlwm tom ntej."

Qhov kev xa khoom no yog qhov kev nkag tau zoo ntawm GNEE lub siab - lub zog siab lub nkoj steel daim hlau rau hauv siab -kawg lag luam ntawm cov teb chaws tsim.

ASTM A517 sib npaug li cas?

ASTM A517 yog sib npaug rauUS T-1 cov ntaub ntawv steel. A517 steel feem ntau yog siv rau hauv fusion welded boilers thiab lwm cov hlab ntsha siab, thaum A514 steel feem ntau siv hauv cov txuas txuas txuas thiab lwm cov qauv. A514 steel kuj sib npaug rau US A709 HPS 100W steel.

Cov khoom siv ASTM A 517 yog dab tsi?

ASTM A517 specification yog Standard Specification rauSiab Vessel Phaj, Alloy Steel, Siab -Lub zog, quenched thiab Tempered khoomsiv nyob rau hauv daim ntawv thov ntawm fusion welded boilers thiab siab hlab ntsha.

Lub zog ntawm ASTM A517 yog dab tsi?

A517 Qib E muaj nyob rau hauv thicknesses mus txog 6.0 nti thiab muaj qhov tsawg kawg nkaus yield zog ntawm100 ksi mus txog 2.5 nti hauv thickness thiab 90 ksi rau daim hlau ntau dua 2.5 nti mus rau 6 nti hauv thickness.

Dab tsi yog qhov txawv ntawm ASTM A514 thiab A517?

Qhov sib txawv tseem ceeb yog lawv qhov kev npaj siv: ASTM A514 yog rau cov ntawv thov xws li txuas hniav thiab cov tsev, thaum ASTM A517 yog rau siab - cov ntawv siv siab xws li boilers thiab cov hlab ntsha. Thaum ob qho tib si yog quenched thiab tempered alloy steels nrog zoo tib yam tshuaj muaj pes tsawg leeg thiab cov khoom zoo sib xws rau cov qib sib xws, A514 ua raws li cov qauv qauv (ASTM A6), qhov A517 yog rau cov hlab ntsha siab (ASTM A20).
