100 * 90 * 5000mm 125 * 75 * 3000mm S235 S275 S355 Bright Kub Rolled Steel H Beam

Peb ci ntsa iab kub dov steel H beams yog engineered kom xa tau tshwj xeeb kev kawm thiab precision, muaj nyob rau hauv standardized specifications ntawm 100 * 90 * 5000mm thiab 125 * 75 * 3000mm, nrog hwm cov khoom qib nrog rau S235, S275, thiab S355. Raws li qib siab - cov khoom siv zoo, cov H beams ua ke qhov zoo ntawm lub teeb kub dov thev naus laus zis nrog cov khoom siv txhim khu kev qha ntawm European tus qauv qauv steels, ua rau lawv zoo tagnrho rau ntau hom kev lag luam, kev tsim kho, thiab kev siv engineering precision uas xav tau qhov tseeb qhov tseeb thiab qhov zoo tshaj plaws.

Qhov ntev ntawm peb H beams -100 * 90 * 5000mm thiab 125 * 75 * 3000mm (sawv cev flange dav * web qhov siab * ntev)- tau ua tib zoo calibrated kom tau raws li cov qauv tsim qauv. Qhov zoo tshaj plaws H-zoo li tus ntoo khaub lig- ntu, tus yam ntxwv los ntawm flanges ruaj khov thiab lub vev xaib nruj, ua kom cov khoom zoo heev-cov kabmob ua haujlwm zoo: cov flanges muab kev tiv thaiv zoo rau dabtsi yog khoov thiab axial compression, thaum lub vev xaib zoo hloov lub zog shear, lav cov qauv kev ruaj ntseg nyob rau hauv ntau yam load. Cov kev ruaj khov no - ntev specifications (3000mm thiab 5000mm) tshem tawm qhov xav tau kev txiav ntxiv hauv feem ntau cov xwm txheej, txhim kho kev tsim kho thiab kev sib dhos ua haujlwm, thiab txo cov khoom pov tseg. Lub ci ntsa iab tiav, lub ntsiab lus ntawm cov txheej txheem ci ntsa iab kub dov, ua kom lub ntsej muag du, tsis muaj qhov tsis xws luag thiab nruj qhov ntev ntev, ua kom zoo dua qhov kev ua tau zoo thiab ua tau zoo nrog lwm yam khoom siv.

S235, S275, thiab S355 European qauv qauv steel qib tsim cov tub ntxhais ntawm peb H beams 'kev ua tau zoo. S235, siv dav siv cov qauv hlau, muaj qhov tsawg kawg nkaus tawm lub zog ntawm 235 MPa thiab zoo heev ductility thiab weldability, haum rau kev siv cov qauv siv. S275 muab kev txhim kho lub zog nrog qhov tsawg kawg nkaus lub zog ntawm 275 MPa, catering rau tej yaam num nrog nruab nrab load- bearing yuav tsum. S355, qib siab -lub zog steel qib, boasts qhov tsawg kawg nkaus lub zog ntawm 355 MPa thiab superior toughness, ua rau nws zoo tagnrho rau hnyav-lub luag haujlwm, siab{15}} kev ntxhov siab ib puag ncig. Tag nrho peb qib feature nruj tswj cov tshuaj muaj pes tsawg leeg, xyuas kom zoo machinability thiab qaug zog kuj. Lawv kev sib raug zoo nrog cov txheej txheem vuam (arc vuam, roj vuam, thiab lwm yam) tso cai rau kev hloov pauv tau yooj yim thiab ntawm - qhov chaw sib dhos, hloov mus rau ntau qhov kev xav tau.

Lub ci kub dov raug txheej txheem yog qhov tseem ceeb hauv kev ua tiav qhov zoo tshaj ntawm peb cov H beams. Tsis zoo li cov pa hluav taws kub dov, ci kub dov muaj kev tswj qhov kub thiab txias thiab cov thev naus laus zis kho saum npoo thaum tsim khoom. Steel billets yog rhuab mus rau qhov zoo tshaj plaws kub (1100-1250 degree) thiab raug mus tas li dov, ua raws li los ntawm nto brightening kev kho mob uas tshem tawm oxide nplai thiab impurities. Cov txheej txheem no tsis yog tsuas yog ua kom zoo dua cov hlau cov qauv, tshem tawm cov teeb meem sab hauv xws li porosity thiab kev sib cais, tab sis kuj tsim kom muaj qhov sib luag, ci ntsa iab nrog qhov tseeb qhov tseeb (siab ntev hauv ± 0.5mm rau qhov loj me). Lub microstructure refined txhim khu H beams ' tensile lub zog, toughness, thiab hnav tsis kam, thaum lub ci ntsa iab txo qhov xav tau ntawm qhov chaw ntxiv, txo cov nqi ntawm qhov project thiab shortening siv cycles.

Peb S235 / S275 / S355 ci kub dov steel H beams (100 * 90 * 5000mm, 125 * 75 * 3000mm) yog dav siv nyob rau hauv precision engineering, industrial rhiav, coj mus muag vaj tse, mechanical khoom ntas, choj auxiliary lug, thiab nyob rau hauv kev tsim kho. Lawv ua haujlwm ua haujlwm tseem ceeb-cov kabmob xws li cov kab hauv pem teb, girders, brackets, thiab framing cov tswv cuab, xa cov kev ua tau zoo thiab kev ntseeg siab. Peb siv cov kev tswj xyuas kom zoo thoob plaws hauv cov txheej txheem tsim khoom- los ntawm kev tshuaj xyuas cov khoom siv raw thiab tshuaj lom neeg muaj pes tsawg leeg rau kev ntsuas cov cuab yeej siv tshuab (tensile, yield, impact), kev txheeb xyuas qhov ntev, thiab kev ntsuas qhov zoo. Txhua batch ntawm H beams tau ntawv pov thawj kom ua tau raws li European EN cov qauv, kom ntseeg tau tias ua raws li kev cai thoob ntiaj teb thiab kev nyab xeeb. Los ntawm kev muab cov siab -precision, siab{16}}zoo ci kub dov H beams, peb muab cov neeg siv khoom nrog cov kev daws teeb meem txhim khu kev qha uas sib npaug ntawm kev ua tau zoo, kev ua haujlwm, thiab tus nqi- ua tau zoo.
