Txoj haujlwm tu thiab txhawb nqa ntawm San Francisco-Oakland Bay Choj hauv Tebchaws Meskas tsis ntev los no tau mus txog qhov tseem ceeb ntawm . 1,000 tons ntawm A709 Qib 50 kub- dov cov qauv hlau customized thiab tsim los ntawm GNEE Steel tau ua tiav tiav. Cov hlau no yuav raug siv los hloov thiab txhim kho tus choj lub thawv steel girders, ua kom muaj kev nyab xeeb ntawm kev tsheb khiav ntawm lub xyoo pua no - qub choj.
Raws li cov hlau tshwj xeeb rau Asmeskas choj engineering, A709 Qib 50 tau dhau los ua cov khoom siv zoo tshaj plaws rau kev saib xyuas choj thiab kev txhawb nqa vim nws qhov zoo heev qis - kub cuam tshuam toughness thiab load- bearing kev ua tau zoo.
Lub caij ntuj no kub nyob rau hauv San Francisco cheeb tsam yog qhov qis, thiab tus choj hlau yuav tsum tiv taus qhov qis - qhov kub thiab txias ib puag ncig ntawm -15℃, uas yuav tsum tau A709 Qib 50 cov qauv hlau kom muaj qhov zoo qis -kub qhov cuam tshuam toughness. Thaum lub sij hawm tsim cov txheej txheem, qhov kev sib tw tseem ceeb rau pab pawg yog yuav ua li cas kom ruaj khov yield zog ntawm cov hlau thaum txhim kho nws qhov qis{10}} kub toughness. Tus kws saib xyuas kev tshaj lij, piav qhia tias: "Peb tau hloov kho qhov sib dhos thiab txo qhov cua txias ntawm cov hlau phaj ntawm 15℃/ s mus rau 10℃/ s, ua rau cov txheej txheem sab hauv ntawm cov hlau tsis sib xws, yog li txhim kho qhov qis -kub toughness." Lub caij no, pab pawg soj ntsuam zoo tau siv cov tshuab ntsuas qhov ntsuas kub qis los ua -15℃kev cuam tshuam rau txhua pawg ntawm cov hlau, kom ntseeg tau tias lub zog cuam tshuam ntau dua 47J. Ntawm lawv, tus yuam sijA709 Qib 50 kub dov structural steel rau choj engineeringtau dhau daim ntawv pov thawj ntawm American Institute of Steel Construction (AISC), thiab tag nrho cov kev ntsuas kev ua tau zoo ua raws li tus qauv choj project.
"Lub San Francisco-Oakland Bay Choj yog lub chaw thauj mus los ntawm San Francisco, thiab nws cov kev saib xyuas thiab kev txhawb nqa lees paub tsis muaj chaw rau kev saib xyuas. Peb tau muab ntau lub tshuab steel thoob ntiaj teb, thiab GNEE's A709 Qib 50 cov qauv hlau sawv tawm feem ntau nyob rau hauv cov nqe lus ntawm qis-kub toughness thiab dimensional, tus thawj coj ntawm US engineer David. Yav dhau los, nws tau ua qhov kev sim nruj ntawm cov qauv tsim los ntawm GNEE thiab pom tias lawv qhov qis - qhov kub thiab txias qhov kev ua tau zoo yog 20% siab dua li cov hlau hauv zos hauv Teb Chaws Asmeskas, ua tau raws li cov kev cai nruj ntawm kev saib xyuas choj. Ntawm qhov chaw xa khoom, David tau coj nws pab neeg los ua cov qauv kuaj xyuas ntawm cov hlau phaj. Thaum pom tias tag nrho cov ntaub ntawv soj ntsuam ua tau raws li cov qauv, nws tau muab tus ntiv tes xoo - nce thiab hais tias: "Qhov zoo ntawm Suav hlau yog kev ntseeg siab."
Txhawm rau ua kom tau raws li qhov kev txhim kho kev ua tiav, GNEE tau txais txoj hauv kev xa tawm, xa cov hlau mus rau San Francisco, Tebchaws Asmeskas hauv 3 pawg. Txhua batch yog nrog los ntawm cov ncauj lus kom ntxaws soj ntsuam thiab cov phau ntawv qhia vuam. Nyob rau tib lub sijhawm, GNEE tau npaj cov neeg ua haujlwm tshaj lij los piav qhia txog kev ceev faj ntawm cov hlau rau US pab neeg tsim kho los ntawm kev sib tham video thiab daws cov teeb meem kev sib ntsib thaum lub sijhawm tsim kho. Qhov kev xa khoom tiav no tsis tsuas yog ua rau GNEE Steel kom tau txais lub hauv paus hauv Teb Chaws Asmeskas siab -kawg choj hlau ua lag luam tab sis kuj tau txhim kho lub npe thoob ntiaj teb kev cuam tshuam ntawm Suav hlau.
Nyob rau hauv lub neej yav tom ntej, GNEE Steel yuav txuas ntxiv mus tob rau nws muaj nyob rau hauv tus choj steel sector. Raws li cov yam ntxwv ntawm huab cua thiab qhov project xav tau ntawm cov cheeb tsam sib txawv, nws yuav hloov kho cov khoom ntawm ntau yam siab -kev ua haujlwm steels, pab txhawb Suav lub zog rau kev nyab xeeb thiab kev ruaj ntseg ntawm lub ntiaj teb choj tej yaam num.
Yog tias koj xav paub ntxiv txog GNEE cov khoom, koj tuaj yeem xa email raualloy@gneesteelgroup.com. Peb zoo siab tshaj los pab koj.
