I-ASTM A572 vs ASTM A992 Wide Flange Beams: Umehluko Oyinhloko, Ukuqhathaniswa Kwamandla kanye Nokukhetha Okuhle Kakhulu

Ezakhiweni zezakhiwo zensimbi zesimanje,Imisebe engu-Windima njengelungu eliyinhloko elimelana nomthwalo wohlaka, okuyinto ukukhethwa kwezinto ezisetshenziswayo okunomthelela omkhulu ekuphepheni kanye nasezindleleni zesakhiwo. Yimiphi umehluko omkhulu phakathi kwezindinganiso ezimbili ezidumile kakhulu emakethe njengamanje -Ibanga lama-50 le-ASTM A572futhiI-ASTM A992Abasebenzi bezobuchwepheshe beRoyal Steel bangabahumushi abaqondile.

I-A992: Indinganiso yemboni eyenzelwe ngqo izinjini "ezibanzi"

Ibanga lama-50 le-A572, yize lidumile embonini yensimbi, i-ASTM A992 'iyindinganiso yegolide' ye-imisebe engu-Wnamuhla.

Umehluko we-Press kanye nohlobo lomkhiqizo: I-A572 iyincazelo ejwayelekile yamapuleti, imigoqo kanye namanye amaphrofayili kodwa i-A992 ingeye-hot-rolled wide-flange bearings.

Ukuthuthukiswa Kwamakhemikhali: I-A992 iqinile kakhulu maqondana nokwakheka kwamakhemikhali, okuholela ekhwalithini yensimbi ephezulu ngokungeza izakhi zokuxuba (i-vanadium, i-niobium, ithusi kanye ne-nickel).

Ukuqhathanisa ukusebenza okuyinhloko: Kungani i-A992 ithatha indawo ye-A572 kancane kancane?

Ekwakhiweni kwesakhiwo, i-A992 ikhombisa izinzuzo ezibalulekile:

Ukulawula Isilinganiso Sokuvumela Ukuthambekela: I-A992 icacisa isilinganiso esiphezulu sokuvunwa-kokudonswa esingekho ngaphezu kuka-0.85. Lokhu kugobeka okuhle kakhulu kuyenza ibe ngcono ezakhiweni ezivame ukuzamazama komhlaba, okwenza kube lula ukumuncwa kwamandla okungcono.

Ukushibilika: Ngenxa yomkhawulo ophezulu oqinile we-A992 ku-carbon equivalent, ukushibilika kwayo ensimini kuzinzile kakhulu kune-A572, okunciphisa ngempumelelo ingozi yokuqhekeka kokushibilika.

Amandla Angaguquguquki: I-A992 icacisa amandla okukhiqiza okungenani angu-50 ksi (cishe i-345 MPa) futhi ibeka umkhawulo wamandla okukhiqiza aphezulu, iqinisekisa ukubikezela okunembile kokucindezeleka ngesikhathi sokuklama kwesakhiwo.

Ukunikezwa kwemakethe kanye nesitifiketi esikabili

Njengomhlinzeki wensimbi ohamba phambili emhlabeni wonke, iRoyal Steel ibone okulandelayo emisebenzini yayo yokuthumela ngaphandle:

Izinga ElizenzakalelayoEzimakethe zezinto zokwakha ezisezingeni eliphezulu eNyakatho Melika naseLatin America,Insimbi ye-Flange ebanzingokuvamile kubhekwa njenge-A992.

Isitifiketi Esiphindwe Kabili: Insimbi ye-A992 esezingeni eliphezulu emakethe ihlangabezana nezidingo ze-A572 Grade 50. Lokhu kusho ukuthi amakhasimende athenga i-A992 avame ukuthola izakhiwo zomzimba ezinhle kakhulu uma kuqhathaniswa ne-A572.

Isincomo seRoyal Steel

"Uma ukhethaimisebe ye-flange ebanzi, uma iphrojekthi yakho ihilela ukushisela okuyinkimbinkimbi noma isendaweni evame ukuzamazama komhlaba, i-A992 iyisinqumo sokuqala esingaphikiswa,” kuphawula inhloko yoMnyango Wezohwebo Wamazwe Ngamazwe weRoyal Steel.

Okwamanje,Insimbi Yasebukhosini YaseShayinaigcina amashumi ezinkulungwane zamathani emininingwane ye-A992 kanye ne-A572 esitokweni emachwebeni afana neTianjin, Qingdao, kanye neShanghai. Njengoba sineminyaka eyi-12 yesipiliyoni ekuthunyelweni kwensimbi kwamanye amazwe, asigcini nje ngokuhlinzeka ngemikhiqizo esezingeni eliphezulu ehlangabezana nezindinganiso ze-ASTM zase-US, kodwa futhi sihlinzeka ngosekelo lobuchwepheshe olwenziwe ngokwezifiso olusekelwe ezidingweni zephrojekthi yamakhasimende ethu.
