Raws li cov kws tshaj lij kev lag luam, peb muab cov- zoo H- ntu kab teeb (xws li I beams) tailored rau kev tsim daim ntawv thov, featuring premium qib Ss400 thiab ASTM A36. Cov khoom kub no - dov cov pa roj carbon me me dub steel cov khoom sib xyaw ua ke cov khoom siv zoo tshaj plaws, kev siv tshuab kub dov, thiab kev ua kom zoo H- ntu qauv tsim, xa cov khoom txhim khu kev qha- cov kabmob muaj peev xwm, kev ua haujlwm zoo, thiab zoo ib yam. Ua haujlwm raws li cov txheej txheem tseem ceeb, lawv tau lees paub los ntawm cov kws tshaj lij kev tsim kho thoob ntiaj teb kom ua tau raws li cov kev xav tau nruj ntawm ntau hom kev tsim vaj tsev.
Hais txog cov khoom tseem ceeb, ob qho tib si Ss400 thiab ASTM A36 yog qhov zoo - suav nrog cov qib carbon me me steel, ua raws li cov qauv thoob ntiaj teb nruj. ASTM A36, uas tau lees paub thoob ntiaj teb qib carbon steel, boasts qhov tsawg kawg nkaus lub zog ntawm 36 ksi (250 MPa) thiab lub zog tensile ntau ntawm 58-79 ksi (400{11}}545 MPa). Nws nthuav tawm tshwj xeeb ductility, weldability, thiab formability, ua rau seamless fabrication txheej txheem xws li txiav, dabtsi yog khoov, drilling, thiab nyob rau hauv - qhov chaw vuam-zoo tagnrho rau kev tsim kho scenarios nrog rau cov kab teeb nyob hauv tsev, cov kab hauv tsev lag luam, thiab lub teeb muaj thav duab. Ss400, Japanese tus qauv carbon me me steel, muaj kev txhim khu kev qha kev ua haujlwm nrog qhov tsawg kawg nkaus lub zog ntawm 235 MPa (rau thickness Tsawg dua lossis sib npaug li 16 hli) thiab zoo toughness. Nws qhov sib npaug ntawm lub zog thiab kev ua tau zoo ua rau nws muaj ntau yam kev xaiv rau ntau yam kev tsim kho, los ntawm cov tsev prefabricated mus rau cov khoom siv cog kev lag luam.
Cov txheej txheem kub-rolled manufacturing txheej txheem yog qhov zoo ntawm cov H-section beams. Thaum lub sij hawm tsim khoom, carbon me me steel billets yog rhuab mus rau qhov kub siab (feem ntau saum toj 1000 degree) thiab txuas ntxiv dov rau hauv H / I hla -sectional profiles. Cov txheej txheem no ua kom zoo dua cov hlau cov qauv nplej, txhim kho cov khoom sib xws, kev ruaj ntseg, thiab cov qauv kev ncaj ncees thaum txo qis hauv kev ntxhov siab thiab qhov tsis xws luag. Qhov tshwm sim kub -rolled carbon me me dub steel nto khaws cov txheej txheem oxide, uas tsis yog tsuas yog muab kev tiv thaiv yooj yim thaum thauj thiab khaws cia tab sis kuj pab txhawb kev kho mob tom ntej yog tias xav tau. H-section (thiab kuv-beam) qauv tsim-tus yam ntxwv los ntawm ob qhov sib npaug flanges txuas los ntawm lub vev xaib nruab nrab- ua kom zoo tshaj qhov kev faib tawm ntawm lub sijhawm khoov, lub zog compressive, thiab shear loads. Cov flanges zoo tiv thaiv kev khoov thiab sab buckling, thaum lub vev xaib xa tawm cov kev ntxhov siab, ua kom lub zog zoo{14}} rau - qhov hnyav piv uas txo cov khoom siv thiab tag nrho cov nqi tsim kho.
Raws li kev tsim kho cov qauv tsim tshwj xeeb, cov Ss400 thiab ASTM A36 H-section beams tau siv dav hauv ntau qhov haujlwm. Lawv ua cov kab teeb ci tseem ceeb, cov kab nruab nrab nruab nrab, kab ke, cov hlua khi, thiab cov hlua khi hauv cov tsev nyob siab- nce siab, cov tsev ua haujlwm, cov chaw lag luam, cov tsev khaws khoom lag luam, cov txuas hniav, thiab cov vaj tse pej xeem. Lawv zoo sib xws nrog ntau yam kev tiv thaiv saum npoo (xws li tiv thaiv - pleev xim rau corrosion, galvanization) txhim khu kev tiv thaiv rau cov av noo, oxidation, thiab muaj corrosion, ncua kev pab cuam lub neej nyob rau hauv ntau yam huab cua thiab kev ua hauj lwm tej yam kev mob. Raws li cov kws tshaj lij kev lag luam, peb ua kom muaj peev xwm ruaj khov, kev tswj xyuas zoo, thiab kev ua tiav tom qab- kev muag khoom, muab cov neeg siv khoom zoo ib yam, siab - cov khoom zoo uas ua tau raws li lub sijhawm teem sijhawm thiab kev ua haujlwm.
Txhawm rau kom ua tiav, peb cov Ss400 thiab ASTM A36 kub- dov cov pa roj carbon me me dub steel H- ntu kab teeb yog tus nqi- cov kev daws teeb meem zoo thiab txhim khu kev qha rau kev tsim kho. Ua ke cov khoom zoo tshaj plaws ntawm cov qib siab carbon me me steel, qib siab kub dov thev naus laus zis, thiab ua kom zoo H-section tsim, lawv xa cov kev ua tau zoo ib yam thiab siv dav. Raws li cov neeg muab kev ntseeg siab, peb tau cog lus tias yuav muab cov khoom zoo siab - cov khoom zoo thiab cov kev pabcuam kev tshaj lij, ua rau cov H- kab teeb no yog ib qho kev xaiv tsis tseem ceeb rau cov haujlwm tsim kho uas xav tau kev ruaj ntseg, kav ntev, thiab tus nqi{10}} ua haujlwm tau zoo.
