Dab tsi yog siv ntawm kub-rolled steel?
Xaiv cov hlau txoj cai yog cov kauj ruam tseem ceeb hauv ib qho phiaj xwm hlau, tab sis muaj ntau hom ntau yam los khaws. Hlau ib leeg muaj ntau qib sib txawv.
Txhawm rau nrhiav cov khoom siv zoo tshaj plaws rau koj qhov project, koj yuav tsum nkag siab tias tus qauv hlau ua tau ntau npaum li cas. Yog tias koj tau saib rau hauv cov hlau xaiv, koj twb tau hnov ntawm kub-rolled steel. Tab sis dab tsi raws nraim yog nws, thiab nws yog dab tsi siv rau?
Dab tsi yog kub-rolled steel?
Kub-Rolled steelyog hom hlau uas tau tsim los ntawm kev dov cov txheej txheem ntawm qhov kub siab heev (feem ntau ib txwm muaj 1,700 degree), uas ua rau cov hlau yooj yim dua thiab ua haujlwm nrog.
Hlau yog rhuab saum toj nws recrystallization kub thiab dhau los ntawm cov menyuam kom ua tiav cov yam xav tau thiab cov duab zoo. Nws txias lawm, ua rau muaj ntxhib, scaled nto.
Tsawg dua qhov ntev ntev (piv rau cov hlau txias-dov steel) vim tias yuav shrinkage thaum cua txias.
Ntxhib, tsis-du nto nrog lub bluish-grey tiav.
Ntau ductile thiab malleable, ua rau nws yooj yim rau daim ntawv mus rau hauv cov qauv loj qauv.
Tus nqi qis dua li txias-rolled steel vim yooj yim ua.
Txheej txheem sib xyaw (I-nqaj, ntsia, raws).
Cov khoom siv tsim kho (daim hlau, cov ntawv txheeb).
Automotive ntas.
Khoom siv ua liaj ua teb.
Kev tsheb ciav hlau kev tsheb ciav hlau.
Npaum li cas yog kub-rolled steel sib txawv los ntawm cov hlau txias-rolled?
Kub-Rolled steel yog dov saum toj no lub recrystallization kub (feem ntau tshaj li 1000 degree), nrog cov hlau hauv lub xeev liab-kub thiab zoo heev. Cov yam ntxwv txheej txheem: tus hlau billet yog ncaj qha dov yam tsis muaj nrab annealing.Txias-Rolled SteelYog dov nyob rau hauv chav nyob hauv qab cov recrystallization kub, nrog lub hardness siab thiab muaj kev deformation siab tiv. Cov yam ntxwv txheej txheem: Feem ntau, kub-rolled hlau coil yog siv los ua cov ntaub ntawv raw, thiab annealing yog qhov yuav tsum tau tom qab dov tom qab ua kom huv.
Nyob rau hauv cov nqe lus ntawm cov neeg kho tshuab, kub-rolled hlau cov khoom pov thawj qis dua lub zog, kev nruj zoo dua, thiab coarser sab hauv nplej. Nws muaj qis dua kev ntxhov siab tab sis qhov chaw txom nyem. Txias-cov hlau, ntawm qhov tod tes, muaj lub zog siab dua thiab hardness (vim ua haujlwm-hardening nyhuv), tab sis qis dua yas. Nws cov nplej tau zoo nkauj thiab nws muaj qhov muaj qhov tseeb siab, ua kom haum rau qhov machision machining.
Cov saum npoo ntawm kub-rolled steel muaj oxide nplai (tsaus xim av) thiab yog ntxhib lossis me ntsis tsis sib xws. Nws yuav tsum tau kua qaub los yog sandblasting los txhim kho nws cov tsos. Lub deg ntawm txias-rolled steel yog du thiab ci, ntawm cov nplai oxide, thiab tuaj yeem siv cov electroplating lossis txau. Cov npoo muaj ntau dua zoo dua thiab dawb ntawm "burrs" feem ntau pom nyob rau hauv kub-rolled steel.
Kub-polled steel feem ntau muaj qhov tuab ntawm ntau dua los yog sib npaug rau cov paib thiab tuaj yeem siv los ua cov phiaj tuab (xws li H-Beams thiab Steel Rails). Nws los nyob rau hauv ntau yam duab tab sis nrog kev ua siab loj loj. Txias-dov hlau tuaj yeem ua tau li nyias tsawg li 0. 1 hli (xws li daim nyias nyias thiab cov ntawv sau ua ke. Nws yog ib feem ntau tiaj tus lossis muaj cov kab hla sib ntxiv (xws li txias-rolled strip hlau).
Dab tsi yog cov khoom ntawm kub-rolled steel?
Kub Rolled SteelYog ib hom hlau tsim los ntawm cov hlau hluav taws xob ua haujlwm rau ntau dua 1 {17}}}} rolling lawv ntawm qhov kub. Cov khoom siv tshuab ntawm kub-rolled steel yog tus cwj pwm los ntawm kev muaj zog nruab nrab thiab muaj zog zoo. Nws lub zog tensile feem ntau yog nruab nrab ntawm {2}} mpa mpa}} mpa mpa}} -30%. Cov xeeb ceem ntawm "tsawg rau nruab nrab lub zog, siab ductility" ua rau nws tsim tshwj xeeb rau kev ua cov xwm txheej yas, xws li kev puas yog khoov. Vim muaj ntuj txias txias tom qab cov nplej kub loj, ua rau muaj kev nyuaj siab (zoo nkauj Qhov feem ntau muaj koob hmoov ntawm kub-rolled steel yog grey dub oxide nplai npog saum npoo av, uas yog cov tshuaj tiv thaiv ntawm cov hlau thiab huab cua thaum muaj cua kub rolling. Qhov saum npoo roughness (RA) feem ntau nyob nruab nrab ntawm 12. {}} Μ m, siab dua li ntawm cov hlau txias-rolled. Qhov seem ntev ntev yog dav (thickness kam rau ± 0. {}}. 5 hli), nrog me me tsis sib xws nyob rau hauv tus ntoo khaub lig-seem. Vim tias tsis muaj mob khaub thuas ua haujlwm tawv, cov kev ntxhov siab nyob sab hauv cov khoom siv me me, ua rau nws tsis tshua muaj kev cuam tshuam thaum ua tiav.
Dab tsi yog siv ntawm kub-rolled steel?
Kub Rolled steel yog dav siv nyob rau hauv ntau daim teb xws li kev tsim kho, tshuab, kev thauj khoom, thiab lub zog vim nws tus nqi qis, thiab ua haujlwm zoo.
Ua tsaug rau nws txoj kev txhim kho thiab tawv tawv, kub-rolled steel cov khoom tuaj yeem hloov kho tau yooj yim rau hauv ib daim ntawv twg koj tuaj yeem xav. Kub-Rolled steel yog nrad feem ntau ntau haiv neeg cov khoom lag luam hauv kev lag luam.
Txawm li cas los xij, kub-rolled steel yog qhov zoo tshaj plaws hauv cov ntawv thov uas yog precometries thiab nruj tolometries tsis xav tau, xws li:
Kev Ua Haujlwm
Lub cev loj ntawm cov qauv hlau: H-puab hlau, I-puab hlau, lub kaum ntse ntse qauv rau cov tuam txhab (xws li Q235B, Q355B kub-rolled hlau). Reinforced pob zeb: HRB400 kub-rolled threaded steel tuav, siv rau ntxiv dag zog pem teb slabs, kab teeb, thiab kab. Tsev Slabs: Kub Rolled steel daim hlau nrog ib tuab ntawm 4-20 hli, siv rau stair treads thiab platform pw.
Kub-Rolled steel lub zog thiab muaj peev xwm yuav tau tsim nyob rau hauv cov ntawv loj ua rau nws txoj kev xaiv zoo rau cov txheej txheem kev tsim kho vaj tse, xws li txuas hniav. Kub-Rolled steel yog nquag siv los ua cov qauv txheem, nrog rau cov khoom sib xyaw thiab cov pob qij txha sib npaug.
Cov Khoom Siv Tuav
Cov neeg tsim khoom xav siv cov hlau kub kub rau qee cov ntaub ntawv tuav cov ntawv thov, xws li cov khoom siv rau diav rawg tsheb, tsheb huv, thiab elevators. Hom hlau no feem ntau siv los ua kom cov thav ntawv, ntsia, pob txha pob, thiab lwm yam.
Dej kis
Kub-Rolled steel kuj zoo tagnrho rau dej cov ntawv thov sib kis, xws li ua kav dej thiab hlab. Kub-Rolled steel kuj tseem siv tau rau kev tsim khoom lag luam ntxiv, xws li cov yeeb nkab sib txuas thiab cov ntu hluav taws xob.
Machinery raug
Kev Siv Machinery: Excavator Dai Daim Hlau (Q690D Kub-Rolled High-zog Hlau), Crane Boom. Cov Machinery tshuab ua liaj ua teb: Tsheb laij teb Chassis, Harvesterter tuaj (65mn kub-rolled caij nplooj ntoos hlav steel). Cheebtsam dav dav: iav cov iav, cov kabmob cov kabmob, thiab lwm yam forging substrates uas xav tau ua tom ntej.
Hom hlau no tseem siv tau dav hauv kev ua liaj ua teb thiab cov khoom siv mining, vim nws lub zog txhim kho thiab muaj peev xwm. Qhov no tso cai rau cov tuam ntxhab ua txhua yam los ntawm kev khoov yooj yim rau cov nyom siv kub-rolled steel.
Feem ntau, koj tuaj yeem pom cov hlau kub siv kub siv nyob rau hauv kev tsim khoom ntawm cov khoom siv xws li sau qoob sau thiab tsheb laij teb. Lawv kuj feem ntau siv los ua cov khoom sib xyaw ua ke thiab cov nyom.
Kev mus
Rail Transit: Stair Rails (U71MN Kub-Rolled Stairs), Tsheb nqaj hlau tsheb (CL60 Hlau). Tsheb tsim: Tsheb nqaj (510l kub-dov automotive nqaj hlau), cov log rims. Lub Nkoj Nkoj: Kub Rolled Steel Daim Phiaj (AH36 \/ DH36) yog siv rau cov qauv nkoj.
Kub Rolled steel tseem muaj cov khoom siv uas nyiam tshaj plaws rau kev lag luam yooj yim vim nws cov txiaj ntsig ntau xyoo dhau los ntawm ntau dua 600 lab tons hauv Suav teb) thiab paub tab prodression technologies. Rau cov khoom sib xyaw uas yuav tsum muaj zog dua lossis qhov tseeb, xws li cov hlua hluav taws xob, ib qho "Rolling + Cleam txias yuav siv tau.
