Kev siv tau zoo ntawm SA 283 Qib C steel hauv kev tsim kho.
Kev siv tau zoo ntawm SA-283 Qib C steel hauv kev tsim kho yog nyob ntawm kev siv nws cov txiaj ntsig tshwj xeeb - zoo heev formability, weldability, thiab zoo sab hauv soundness-thaum ua tib zoo saib xyuas nws lub zog qis dua piv rau cov qauv hlau zoo li A36. Nws siv tau zoo tshaj plaws hauv cov ntawv thov uas tseem ceeb tshaj plaws kev tsim khoom thiab kev ntseeg siab tshaj qhov muaj peev xwm ua tau zoo.
SA 283 Qib C yog dab tsi?
SA 283 Qib C yog cov pa roj carbon steel phaj tshwj xeeb los ntawm ASME (American Society of Mechanical Engineers) Boiler thiab Pressure Vessel Code, Tshooj II, Ntu A. Nws yog ib qho dav - lub hom phiaj, qis rau nruab nrab tensile lub zog steel feem ntau siv rau kev siv cov qauv thiab nruab nrab siab.
Nws qhov zoo tshaj plaws thiab feem ntau lees txais sib npaug yog nyob rau hauv ASTM A283 specification thiab thoob ntiaj teb cov qauv.
Nov yog qhov kev faib tawm ntawm SA 283 Qib C siv tau zoo thiab cov kev xav tseem ceeb:
Kev siv tau zoo hauv kev tsim kho
1.Non-Tsev Txheej Txheem & Architectural Cheebtsam:
Lub Tsev Cladding & Vaj Huam Sib Luag: Nws cov ductility zoo tshaj plaws tso cai rau qhov txias txias - ua rau cov duab kos duab (xws li, cov ntawv corrugated, fascia) tsis tawg.
Stair Treads, Plate Plate, & Walkways: Rau cov tsis yog -thawj thauj khoom- cov kabmob uas muaj zog nruab nrab thiab yooj yim weldability txaus.
Purlins, Girts, & Light Framing: Hauv qis- nce cov tsev lag luam lossis cov tsev khaws khoom uas cov khoom thauj me me.
2.Storage & Containment Structures (Nws Lub Ntsiab Tseem Ceeb):
Dej Cia Tank & Silos: Nws ib nrab-tua / tua deoxidation ua kom lub suab zoo sab hauv, txo qhov kev pheej hmoo ntawm laminations lossis porosity hauv welded seams, uas yog qhov tseem ceeb rau cov kua / huab cua nruj.
Hopper Bins, Chutes, & Ductwork: Qhov twg puas yog tsis hnyav, thiab cov khoom tsim tawm yog qhov tseem ceeb rau kev tsim khoom.
3.Base Phaj, Shims, & Non-Load-Bearing Fabrications:
Qhov twg nws 30 ksi yield zog txaus, thiab nws zoo ib yam los ntawm guaranteed chemistry (xws li, min. 0.90% Mn) kom ntseeg tau tias vuam thiab kev ua tau zoo.
Cov txiaj ntsig tseem ceeb rau kev siv tau zoo
Predictable Fabrication: Cov ntsiab lus ntawm manganese yam tsawg kawg nkaus tau lees paub thiab raug tua / ib nrab -tua kev xyaum ua rau:
Superior Weldability: Tsis tshua muaj kev pheej hmoo ntawm vuam tawg; tsim suab, ductile welds.
Kev Ua Txias Zoo Tshaj Plaws: tuaj yeem khoov, dov, lossis xuas nrig ntaus ntau dua li siab dua - lub zog steels yam tsis ua haujlwm.
Uniform Properties: Ntau tus cwj pwm zoo sib xws thaum tsim khoom dua li cov hlau rimmed zoo li qee qhov A36.
Tus nqi-Kev ua tau zoo rau cov haujlwm tshwj xeeb: Feem ntau siv nyiaj ntau dua - lub zog steels thaum nws lub zog qis dua tsis yog qhov txwv, thiab nws cov ntaub ntawv txo cov nqi zog.
Cov kev txwv tseem ceeb & kev txiav txim siab rau kev siv tau zoo
1.Strength Limitation (30 ksi Yield):
Kev siv tsis zoo: Rau thawj qhov kev thauj khoom-cov tswv cuab (kab kab, kab, kab, trusses) hauv cov qauv tseem ceeb. Nws yuav xav tau qhov loj dua, hnyav dua piv rau A36 (36 ksi) lossis A572 Gr. 50 (50 ksi), tsis lees paub cov khoom siv nyiaj txuag.
Txoj cai: Tsis txhob hloov SA-283 Gr. C rau A36 hauv kev tsim qauv yam tsis muaj kev suav rov ua tiav thiab rov ua cov tswv cuab los ntawm tus kws ua haujlwm.
2.Tsis yog rau Dynamic/Fatigue-Cov ntawv thov tseem ceeb:
Nws tsis muaj qhov yuav tsum tau muaj kev cuam tshuam toughness. Nws tsis tsim nyog rau cov qauv uas raug cuam tshuam, kev thauj khoom poob siab, lossis qis - qhov kev pabcuam kub tshwj tsis yog tias muaj kev ntsuas ntxiv.
3. Kev Ua Raws Cai:
Nws tsis yog thawj cov qauv hlau hauv cov lej loj hauv tsev xws li AISC. Kev qhia nws rau cov qauv thav duab yuav xav tau kev pom zoo tshwj xeeb thiab kev ncaj ncees.
Nws thawj tus lej hauv tsev yog ASME Boiler & Pressure Vessel Code rau siab - khaws cov khoom.
Summary : Siv Yis Ntuj Neeb
SA-283 Qib C yog siv tau zoo tshaj plaws hauv kev tsim kho raws li "fabricator's steel" rau cov khoom tsis tseem ceeb, tsim, thiab welded cov khoom uas nws cov ductility, uniformity, thiab weldability muab cov txiaj ntsig zoo, thiab nws lub zog qis tsis yog qhov tsis zoo.
Xav tias nws yog cov khoom siv zoo tshaj plaws rau "daim tawv nqaij thiab ntim" ntawm cov qauv es tsis yog nws "skeleton." Nws siv tau zoo nyob rau hauv daim ntawv thov xws li tso tsheb hlau luam, architectural metalwork, thiab lub teeb theem nrab, qhov twg nws cov kev ua tau zoo nyob rau hauv lub khw txhais ncaj qha mus rau ib tug txhim khu kev qha, tus nqi - zoo kawg nkaus khoom.
SA 283 Qib C sib npaug li cas?
ASME SA 283 Gr C cov khoom sib npaug hauv EN tus qauv yog S235JR steel. S235JR steel muaj zoo plasticity, toughness thiab weldability, tej yam zog thiab zoo txias dabtsi yog khoov zog.
ASTM A283 Qib C yog dab tsi?
ASTM A283 Qib C yog qhov tshwj xeeb rau qis thiab nruab nrab tensile lub zog carbon steel daim hlau ntawm cov qauv zoo rau kev siv dav dav. ASTM A283 Qib C muaj qhov ntsuas qhov ua tau zoo ntawm 30 ksi.
Qhov txawv ntawm A283 C thiab A36 C yog dab tsi?
A36 muaj cov ntsiab lus qis dua piv rau A283 Qib C, ua rau nws yooj yim rau vuam thiab ductile ntau dua. Mechanical Properties: A283 Qib C: siab zog thiab siab yield point piv rau A36, ua rau nws haum rau siab - siv zog.
Dab tsi yog qhov tso cai kev ntxhov siab rau A283 Qib C?
Cov qib carbon feem ntau, suav nrog Sa 283 Gr C, muaj qhov siab tshaj plaws tso cai ntawm 13,750psi.
Qhov txawv ntawm SA 283 C thiab SA 36 yog dab tsi?
Alloy Composition
Cov kev sib txawv no qhia tias A36 yuav nyiam rau cov ntawv thov uas xav tau lub zog ntau dua thiab ua rau qaug zog zoo dua, thaum SA283 Qib C tuaj yeem tsim nyog rau cov ntawv thov uas cov khoom siv zog me ntsis tau txais thiab muaj peev xwm raug nqi ntau dua - zoo.
Tag nrho cov specification thiab cov ntsiab lus muaj nyob rau ntawm kev thov. Cov ntaub ntawv saum toj no yog muab rau kev taw qhia nkaus xwb. Rau kev tsim tshwj xeeb thov hu rau peb cov neeg ua haujlwm muag khoom.
