Peb Q235 H Beam Steel Wide Flange Beams sawv ntsug raws li kev ntseeg siab thiab tus nqi -kev ua haujlwm zoo, tsim kom tau raws li qhov xav tau ntawm ntau hom kev tsim kho. Raws li Suav lub teb chaws tus qauv GB / T 700, Q235 carbon steel muaj npe nrov rau nws cov khoom siv sib luag, thaum lub dav flange tsim txhim kho cov qauv kev ua haujlwm zoo - ua cov kab teeb no zoo tagnrho rau cov vaj tsev nyob, kev lag luam, thiab lub teeb kev lag luam uas yuav tsum tau muaj kev ruaj khov -cov kabmob kev ua haujlwm thiab kev lag luam tsim.
Peb Q235, Q345, A36, S235JR, S355JR, thiab SS400 Structural H Steel sawv cev rau kev nthuav dav ntawm cov txheej txheem siab - kev ntseeg tau ntawm cov qauv kev daws teeb meem, tsim kho kom haum rau kev tsim kho thoob ntiaj teb kev xav tau thoob plaws hauv thaj chaw, kev lag luam, kev lag luam, thiab kev tsim vaj tsev. Npog cov qauv tseem ceeb thoob ntiaj teb thiab lub teb chaws -GB / T 700 (Q235), GB / T 1591 (Q345), ASTM A36 (A36), EN 10025 (S235JR, S355JR), thiab JIS G 3101 (SS400) {{20}cov khoom siv sib xyaw ua ke zoo tshaj plaws, kev ua haujlwm zoo tshaj plaws ntawm H. kev ua tau zoo. Tsim los ua cov khoom tseem ceeb-cov kabmob, lawv ua kom muaj kev nyab xeeb, ua haujlwm ntev, thiab tus nqi- ua haujlwm tau zoo rau ntau qhov kev xav tau.
Lub versatility ntawm peb Cov Qauv H Steel nyob rau hauv qhov ua tib zoo xaiv ntau yam ntawm cov qib steel, txhua tus haum rau kev thauj khoom tshwj xeeb -cov kabmob thiab ib puag ncig xav tau. Q235 (Suav tus qauv) yog ib tug dav - lub hom phiaj carbon steel nrog ib tug tsawg kawg nkaus yield zog ntawm 235 MPa, zoo tagnrho rau lub teeb rau nruab nrab- lub luag hauj lwm qauv. Q345 (Suav tus qauv), siab -lub zog qis- alloy steel, muaj qhov tsawg kawg nkaus yield zog ntawm 345 MPa, xa cov khoom muaj peev xwm ntxiv rau kev siv hnyav dua. A36 (Asmeskas tus qauv) tau txais kev ntseeg siab thoob ntiaj teb nrog qhov tsawg kawg nkaus lub zog ntawm 250 MPa thiab sib npaug tensile lub zog (400-545 MPa) rau kev siv ntau yam qauv. S235JR (European standard) muab kev ntseeg tau zoo nrog 235 MPa yield zog, thaum S355JR (Tebchaws Europe tus qauv) nce lub zog mus rau 355 MPa rau hnyav-cov dej num hauv vaj tse. SS400 (Japanese tus qauv) ua kom muaj kev ua haujlwm zoo ib yam nrog 245 MPa yield zog rau kev tsim kho. Txhua qib muaj cov tshuaj tswj cov tshuaj muaj pes tsawg leeg (cov ntsiab lus tsis tshua muaj carbon tsawg, cov impurities tsawg) uas lav zoo ductility, toughness, thiab weldability-tseem ceeb rau cov qauv resilience thiab hloov tau yooj yim fabrication.
Lub iconic H-zoo li tus ntoo khaub lig-sectional tsim ntawm peb cov qauv hlau yog lub hauv paus ntawm nws cov qauv kev ua tau zoo. Muaj ob lub flanges sib npaug sib txuas los ntawm lub vev xaib hauv nruab nrab, qhov geometry no ua kom pom kev ntxhov siab nyob rau hauv axial, dabtsi yog khoov, thiab shear loads, xa tshwj xeeb khoov nruj thiab torsional tsis kam. Piv nrog rau lwm cov qauv txheej txheem, H steel txo cov khoom pov tseg thaum ua kom muaj peev xwm ua haujlwm ntau tshaj -cov kabmob muaj peev xwm, ua rau kev tsim cov qauv sib dua, kev lag luam ntau dua. Cov flanges sib npaug kuj tseem muab thaj chaw sib txuas loj rau kev sib txuas nrog cov kab, hauv pem teb slabs, thiab brackets, txhim kho kev sib koom ua ke thiab ua kom yooj yim ntawm - qhov chaw tsim kho.
Tag nrho peb cov khoom siv Structural H Steel yog tsim los ntawm cov txheej txheem kub dov, ua rau kub tshaj 1000 ° C. Qhov siab - txheej txheem kub no tshem tawm cov kev ntxhov siab sab hauv hauv cov hlau, ua kom muaj kev ruaj ntseg ntawm qhov ntev thiab ntev - lub sij hawm kev ncaj ncees ntawm cov khoom- qhov tseem ceeb rau cov khoom siv thauj khoom tsis tu ncua. Kub dov kuj ua tiav cov khoom siv sib xws, tshem tawm cov txheej txheem microstructural inconsistencies uas tuaj yeem cuam tshuam kev ua haujlwm. Cov txheej txheem txhim kho formability, tso cai rau H-zoo li profile yuav tsum tau ua nrog meej qhov ntev thiab du nto thoob plaws txhua qib steel. Tsis tas li ntawd, qhov zoo tshaj plaws weldability ntawm cov qib no (tshaj nrog arc vuam, MIG / MAG vuam, TIG vuam) ua kom tsis muaj kev sib haum xeeb ntawm kev txiav, drilling, thiab khoov, hloov mus rau qhov tsim tshwj xeeb.
Txhawm rau kom ntseeg tau tias muaj txiaj ntsig zoo thiab ua raws li cov qauv thoob ntiaj teb, txhua pawg ntawm peb Q235, Q345, A36, S235JR, S355JR, thiab SS400 Structural H Steel tau dhau los ua cov txheej txheem tswj xyuas zoo. Kev tshuaj xyuas muaj xws li kev tshuaj ntsuam xyuas cov tshuaj muaj pes tsawg leeg (ntawm kev ntsuam xyuas spectrometric) txhawm rau txheeb xyuas cov khoom siv purity, kev ntsuam xyuas cov cuab yeej cuab tam (lub zog tensile, yield zog, elongation, cuam tshuam toughness) kom paub meej cov kev ntsuas kev ua tau zoo, thiab qhov ntsuas qhov tseeb (siv cov cuab yeej ntsuas ntsuas) kom ua raws li cov lus qhia tshwj xeeb. Kev tshuaj xyuas qhov zoo ntawm qhov chaw kuj tseem ua kom txo qis qhov tsis xws luag xws li tawg, nplai, thiab indentations. Tag nrho cov khoom yog nrog los ntawm cov ncauj lus kom ntxaws daim ntawv pov thawj zoo thiab cov ntaub ntawv ntsuam xyuas cov ntaub ntawv, xyuas kom meej tag nrho traceability thiab kev cia siab rau engineers thiab cov neeg cog lus.
