Lub kaum sab xis steeltuaj yeem tsim los ntawm ntau yam kev ntxhov siab raws li kev xav tau sib txawv ntawm cov qauv, thiab tuaj yeem siv los ua ib qho txuas ntawm cov khoom sib txuas. Dav siv nyob rau hauv ntau lub tsev thiab engineering cov qauv, xws li kab teeb, txuas hniav, kis tau tus yees, nqa thiab tsheb thauj mus los machinery, ships, industrial furnaces, tshuaj tiv thaiv yees, thawv racks, cable trench txhawb, hwj chim piping, busbar txhawb installation, thiab warehouses txee thiab lwm yam.
Hom lub kaum sab xis steel: feem ntau muab faib ua ob hom: lub kaum sab xis ntawm lub kaum sab xis steel thiab lub kaum sab xis tsis sib npaug, ntawm qhov tsis sib xws ntawm lub kaum sab xis steel tuaj yeem muab faib ua ob hom: sab tsis sib npaug thiab sib npaug thickness thiab tsis sib npaug sab thiab tuab tuab.

Standard carbon angle steel, muaj nyob rau hauv ob qho tib si sib npaug thiab tsis sib npaug configurations, yog lub hauv paus kub-rolled structural profile yam ntxwv los ntawm nws txoj cai-angle L-zoo li tus ntoo khaub lig-section. Nws ua haujlwm tseem ceeb hauv kev tsim kho thoob ntiaj teb, kev tsim khoom siv tshuab, kev tsim vaj tsev engineering, thiab cov ntawv thov kev lag luam, muaj npe nrov rau nws cov khoom siv zoo heev -cov kabmob muaj peev xwm, kev ua haujlwm ruaj khov, kev ua haujlwm yooj yim, thiab tus nqi- ua haujlwm tau zoo. Peb cov khoom lag luam suav nrog ntau yam kev lees paub thoob ntiaj teb cov qib carbon steel, suav nrog S235jr, S275jr, A572 Gr50, A572 Gr60, A36, thiab SS400, ua ke nrog ob qho tib si sib npaug thiab tsis sib npaug ntawm lub kaum sab xis tsim, ua kom tiav cov kev xav tau ntawm ntau yam khoom siv thiab cov qauv tsim.

Lub kaum sab xis steel peb muab tau muab faib ua ob hom qauv tseem ceeb: lub kaum ntse ntse sib npaug thiab lub kaum sab xis tsis sib xws, txhua tus tsim kho kom haum rau kev thauj khoom tshwj xeeb -cov xwm txheej. Lub kaum sab xis steel nta ob txhais ceg ntawm qhov ntev zoo ib yam, ua kom muaj kev sib npaug sib npaug thiab sib dhos yooj yim. Nws yog dav siv nyob rau hauv symmetric structural Cheebtsam xws li lub ru tsev trusses, lub tsev thav duab, ntoo khaub lig braces, thiab lub teeb -lub luag hauj lwm machinery kev txhawb nqa, nyob rau hauv ib qho tseem ceeb load kis tau tus mob. Lub kaum sab xis steel tsis sib xws, muaj ob txhais ceg ntawm qhov ntev sib txawv, muab kev hloov kho kom yooj yim hauv cov qauv tsim asymmetric. Nws cov duab tshwj xeeb tso cai rau nws ua tau zoo dais tsis sib luag, ua rau nws zoo tagnrho rau cov khoom siv choj, crane brackets, shipbuilding structures, thiab cov cuab yeej siv hauv tsev, qhov kev ruaj ntseg hauv cov txheej txheem nyuaj yog qhov tseem ceeb.

Tag nrho peb cov khoom lag luam steel yog tsim los ntawm cov qib siab - cov qauv zoo carbon steel qib, txhua qhov ua tau raws li cov qauv thoob ntiaj teb nruj thiab muaj cov khoom siv sib txawv kom haum rau ntau yam kev thov. S235jr, European EN tus qauv carbon structural steel, yog tus nqi - kev xaiv zoo nrog cov ductility zoo thiab weldability. Featuring lub zog tsawg kawg nkaus ntawm 235 MPa thiab lub zog tensile ntawm 360-510 MPa, nws yog qhov tsim nyog rau cov khoom siv hluav taws xob qis xws li scaffolding, phab ntsa txhawb nqa, thiab cov qauv tsim yooj yim.

S275jr, kuj ua raws li European EN cov qauv, muab kev ua haujlwm zoo dua qub piv rau S235jr. Nrog rau qhov tsawg kawg nkaus tawm lub zog ntawm 275 MPa thiab lub zog tensile ntawm 370-510 MPa, nws nthuav tawm cov kev cuam tshuam zoo (tsim nyog nyob rau hauv chav tsev kub) thiab thauj khoom-cov kabmob muaj peev xwm, ua rau nws tsim nyog rau cov haujlwm nruab nrab hnyav xws li kev cob qhia thav duab, choj girders, thiab cov cuab yeej siv hnyav.

ASTM A36, Asmeskas tus qauv qis- carbon structural steel, tau lees paub thoob ntiaj teb rau nws qhov kev ua tau zoo tshwj xeeb. Boasting qhov tsawg kawg nkaus lub zog ntawm 250 MPa, lub zog tensile ntawm 400-550 MPa, thiab qhov tsawg kawg nkaus elongation ntawm 20%, nws ua ke zoo weldability, formability, thiab toughness. ASTM A36 lub kaum sab xis steel yog dav siv hauv loj-tej kev tsim kho thiab kev tsim kho vaj tse, suav nrog- nce lub tsev thav duab, offshore platforms, thiab cov khoom siv hnyav.

A572 Gr50 thiab A572 Gr60 yog siab -lub zog qis- alloy (HSLA) qib steel ua raws li American ASTM cov qauv, tsim los rau siab - load structural applications. A572 Gr50 nta lub zog qis kawg nkaus ntawm 345 MPa thiab lub zog tensile ntawm 450-580 MPa, thaum A572 Gr60 muaj qhov tsawg kawg nkaus lub zog ntawm 414 MPa thiab lub zog tensile ntawm 517-655 MPa. Ob qib qhia tau zoo heev corrosion kuj thiab toughness, ua rau lawv zoo tagnrho rau xav tau tej yaam num xws li loj-span txuas hniav, high-sawv tsev kab, thiab crane ntsia.

SS400, Japanese standard carbon structural steel, yog ib tug ntau yam thiab dav siv qib nrog tsawg carbon cov ntsiab lus, zoo toughness, thiab zoo heev weldability thiab formability. Nrog lub zog tensile ntau ntawm 400-510 MPa thiab qhov tsawg kawg nkaus lub zog ntawm 245 MPa, nws sib npaug kev ua tau zoo thiab tus nqi -effectiveness, haum rau kev siv cov qauv xws li lub tsev thav duab, lub teeb lub luag hauj lwm machinery bases, thiab brackets.

Tag nrho peb cov khoom sib npaug thiab tsis sib npaug ntawm cov khoom siv steel hlau yog tsim los ntawm kev siv tshuab kub siab heev - dov. Thaum lub sij hawm tsim khoom, siab - zoo steel billets yog rhuab mus rau qhov kub siab (feem ntau saum toj no 1050 degree) thiab txuas ntxiv dov mus rau hauv meej L-zoo li tus ntoo khaub lig- ntu, kom ntseeg tau tias cov qauv sab hauv, ntom ntom, thiab qhov tseeb qhov ntev ntev. Cov txheej txheem no tshem tawm cov teeb meem sab hauv xws li pores thiab inclusions, txhim kho tag nrho cov kav ntev thiab kev ntseeg siab ntawm cov khoom.

Ua ntej tawm hauv lub Hoobkas, txhua pawg ntawm lub kaum sab xis steel tau ua tib zoo tshuaj xyuas raws li cov txheej txheem thoob ntiaj teb, suav nrog kev ntsuas qhov ntev, ntsuas cov cuab yeej cuab tam, tshuaj lom neeg muaj pes tsawg leeg, thiab kuaj xyuas qhov zoo. Qhov no ua kom ntseeg tau tias txhua yam khoom ua tau raws li qhov kev xav tau ntawm kev ua tau zoo thiab tsim nyog rau lawv cov kev xav tau. Nrog rau ntau yam ntawm cov ntaub ntawv qib, ob hom qauv, txhim khu kev qha zoo, thiab kev ua tau zoo dua, peb cov qauv carbon steel tau dhau los ua qhov kev xaiv zoo tshaj plaws rau engineers, neeg cog lus, thiab manufacturers thoob ntiaj teb, muab cov qauv kev daws teeb meem zoo rau ntau yam engineering.
