Kub dov SS400-SS540 series 200X200 steel lub kaum sab xis, ib qho loj - loj sib npaug ntawm lub kaum sab xis steel nrog txoj cai- kaum sab xis L-zoo li tus ntoo khaub lig- ntu, tshwj xeeb yog tsim los rau hnyav- lub luag haujlwm daim ntawv thov kev ua haujlwm uas xav tau kev ua haujlwm siab bearing muaj peev xwm thiab kev ua haujlwm zoo heev{11}. Raws li cov khoom tseem ceeb hauv lub kaum sab xis steel, nws yog tsim los ntawm kev kub siab- dov technology thiab nruj me ntsis raws li cov qauv kev lag luam, kev sib koom ua ke ntawm cov khoom zoo tshaj plaws thiab kev tswj xyuas kom meej kom tau raws li cov kev xav tau ntawm cov haujlwm loj hauv engineering.
Nyob rau hauv cov nqe lus ntawm cov khoom qib, lub kaum sab xis steel no tsuas yog npog SS400 rau SS540 series, uas yog siab - zoo carbon structural steels nrog maj txhim kho txhua yam khoom. SS400, raws li qib theem pib hauv cov koob, nta zoo toughness, zoo heev weldability thiab formability, ua rau nws haum rau dav dav -cov dej num raws li cov qauv uas dais nruab nrab loads. SS540, raws li qib siab - lub zog, khav theeb lub zog tensile ntau dua thiab lub zog tawm los, ua kom nws tuaj yeem tiv taus ntau dua li qub thiab muaj zog, thiab tau siv dav hauv cov txheej txheem tseem ceeb uas yuav tsum muaj kev nyab xeeb thiab ua haujlwm ntev. Tag nrho SS400-SS540 series tswj cov tshuaj lom neeg muaj pes tsawg leeg tswj, ua kom cov khoom ruaj khov thiab cov qauv zoo sib xws, uas ua rau lub hauv paus ruaj khov rau lub neej ua haujlwm ntev ntawm lub kaum sab xis steel hauv qhov chaw ua haujlwm hnyav.
200X200 specification yog hais txog qhov sib npaug ntawm sab ntev ntawm lub kaum sab xis steel, nrog rau ob sab ntsuas 200mm, uas yog ib qho loj loj - loj specification nyob rau hauv vaj huam sib luag cov khoom steel. Qhov loj sab ntev tsim no ua rau kom tus ntoo khaub lig-sectional cheeb tsam thiab lub sij hawm ntawm inertia ntawm lub kaum sab xis steel, zoo heev txhim khu nws load- bearing peev, dabtsi yog khoov kuj thiab torsion kuj piv nrog me me thiab nruab nrab- lub kaum sab xis steels. Qhov tseeb qhov tseeb ntawm 200X200 specification yog nruj me ntsis tswj thaum lub sij hawm tsim khoom, nrog me me deviations nyob rau hauv sab ntev, thickness thiab txoj cai -lub kaum sab xis degree, kom nruj haum thiab ruaj khov sib dhos thaum lub sij hawm installation, thiab zoo txhim kho tag nrho cov qauv rigidity thiab kev ruaj ntseg ntawm qhov project.
Hais txog kev siv thev naus laus zis, lub kaum sab xis steel no siv cov txheej txheem kub kub- dov ntau lawm. Thaum lub sij hawm kub dov, steel billet yog rhuab mus rau qhov kub siab (feem ntau tshaj 1000 degree) thiab ces dov mus rau hauv qhov yuav tsum tau L-zoo li tus ntoo khaub lig-section los ntawm kev nruam dov mills. Cov txheej txheem no tsis tsuas yog ua rau cov qauv sab hauv ntawm lub kaum sab xis steel zoo li qub thiab ntom ntom, tshem tawm cov teeb meem sab hauv xws li lub qhov hws thiab suav nrog, tab sis kuj txhim kho cov ductility thiab toughness ntawm cov khoom, tsis txhob nkig tawg hauv kev siv tswv yim. Piv nrog rau txias -rolled lub kaum sab xis steel, qhov kub- dov SS400-SS540 series 200X200 steel lub kaum sab xis muaj qhov zoo ntawm cov nqi qis dua, kev hloov pauv tau zoo dua rau kev ua haujlwm hnyav (xws li txiav, drilling thiab vuam), thiab yog qhov tsim nyog rau cov ntawv loj loj {{15} loj.
Qhov no kub dov SS400-SS540 series 200X200 steel lub kaum sab xis yog dav siv nyob rau hauv ntau yam hnyav-duty engineering teb, nrog rau loj- nplai lub tsev thav duab, choj qauv, crane kab teeb, shipbuilding, mechanical equipment bases, steel structure rhiav thiab offshore platforms. Nws cov kev ua tau zoo tshaj plaws tso cai rau nws hloov mus rau kev ua haujlwm nyuaj xws li kev thauj khoom siab, cov av noo thiab nquag siv tshuab kev co. Ua ntej tawm hauv lub Hoobkas, tag nrho cov khoom tau raug soj ntsuam nruj nruj, nrog rau kev ntsuas qhov ntev, ntsuas cov cuab yeej cuab yeej thiab tshuaj xyuas qhov zoo, xyuas kom meej tias txhua pawg ntawm cov khoom ua tau raws li cov qauv tsim nyog. Nrog nws cov kev txhim khu kev qha zoo, kev ua haujlwm ruaj khov thiab tsim nyog cov qauv tsim, nws tau dhau los ua cov khoom siv zoo tshaj plaws rau cov haujlwm ua haujlwm hnyav.
