Raws li cov khoom siv tseem ceeb hauv kev lag luam niaj hnub thiab kev tsim kho, kev tshawb fawb thiab kev tsim cov txheej txheem rau carbon steel profiles ncaj qha cuam tshuam rau cov khoom siv kho tshuab, qhov tseeb ntawm qhov tseeb, thiab kev pabcuam lub neej.Cov kab lus no piav qhia txog cov txheej txheem ua tiav carbon steel profile, los ntawm raw cov ntaub ntawv mus rau cov khoom tiav, npog cov txheej txheem tseem ceeb thiab kev tswj xyuas zoo.
Kev npaj raw khoom
Kev tsim cov pa roj carbon steel profiles pib nrog kev xaiv cov qib siab - zoo carbon structural steel los yog qis - alloy steel. Cov ntaub ntawv nyoos feem ntau yog muab rau hauv daim ntawv ntawm cov pob zeb nruam nruam, cov khoom siv, lossis kub - dov billets. Lawv cov tshuaj muaj pes tsawg leeg (piv txwv li, carbon cov ntsiab lus, manganese, silicon, thiab lwm yam alloying ntsiab) yuav tsum nruj me ntsis raws li lub teb chaws cov qauv (xws li GB/T 700{13}}2006) kom ruaj ntseg thaum lub sij hawm tom ntej ua. Thaum tuaj txog, cov khoom siv raw tau raug kuaj xyuas qhov tsis xws luag (piv txwv li, cov kab nrib pleb, suav nrog), ntsuas qhov ntev, thiab kev tshuaj ntsuam xyuas muaj pes tsawg leeg. Unqualified batches raug tso tseg.
Cua sov thiab Pretreatment
Txhawm rau txhim kho cov hlau plasticity thiab txo nws qhov tsis kam mus rau deformation, cov billets tau rhuab rau hauv lub qhov cub hluav taws xob tas li los yog lub qhov dej ntub rau qhov kub ntawm 1100-1250℃(qhov kub tshwj xeeb txawv nyob ntawm qib steel). Thaum lub sij hawm cua sov txheej txheem, lub cub tawg cua yuav tsum tau tswj (kom tsis txhob oxidation thiab decarburization), thiab kub uniformity yuav tsum tau saib xyuas nyob rau hauv lub sij hawm ntawm siv thermocouples. Tom qab preheating, lub billet undergoes deg tu (xws li, high-pressure dej descaling) kom tshem tawm nplai thiab tiv thaiv tsis xws luag los ntawm nias rau hauv lub profile nto thaum dov.
Rolling thiab tsim
Rolling yog cov txheej txheem tseem ceeb rau kev tsim cov carbon steel profiles thiab muaj ob theem: roughing thiab xov. Roughing siv lub siab-txo zeb (xws li ob- lossis plaub- yob rov qab zeb) kom maj mam txo cov billet tus ntoo khaub lig-section los ua ib qho kev kwv yees ntawm qhov profile. Kev ua tiav dov siv lub universal zeb los yog nruam dov zeb los kho tus ntoo khaub lig-sectional geometry (piv txwv li, flange thickness ntawm I- kab teeb thiab duav qhov siab ntawm cov channel) nyob rau hauv siab -precision tswj. Thaum lub sij hawm dov, qhov sib txawv ntawm dov thiab dov ceev yuav tsum tau hloov kho kom zoo los xyuas kom meej qhov sib txawv ntawm txhua ntu, thiab qhov sib txawv ntawm qhov sib txawv tau saib xyuas hauv lub sijhawm tiag tiag uas siv cov kab kab hauv online.
Kev kho cua sov thiab cua sov
Txoj kev txias rau dov profiles yog xaiv raws li lawv qhov kev npaj siv:
1.Natural Cooling: Cov txheej txheem zoo ib yam (xws li Q235 steel) feem ntau yog huab cua- txias rau chav sov kom khaws lawv cov tawv tawv qub.
2.Controlled Cooling: Siab -lub zog profiles (xws li Q345 steel) siv laminar txias los yog tshuaj tsuag txias. Los ntawm kev tswj tus nqi cua txias, siab -lub zog profiles ua kom cov nplej loj thiab ua kom muaj zog.
3.Kev kho cua sov: Qee qhov profile rau kev siv tshwj xeeb xav tau normalizing, annealing, los yog tempering (quenching thiab tempering) kom optimize lawv tag nrho cov neeg kho tshuab zog.
Tiav thiab Kev Tshuaj Xyuas
Tom qab txias, cov profiles nkag mus rau theem tiav, uas suav nrog:
•Straightening: Cov menyuam straighteners los yog nias straighteners yog siv los tshem tawm dabtsi yog khoov los yog distortion los ntawm dov residual kev nyuaj siab.
• Txiav: Saws lossis nplaim taws txiav yog siv los txiav cov profiles kom ntev (xws li 6 meters lossis 12 meters). Cov txiav yuav tsum du thiab burr -dawb.
• Kev Kho Nto: Kev txhaj tshuaj, roj, lossis galvanizing tuaj yeem ua raws li qhov xav tau rau kev tshem tawm xeb thiab tiv thaiv corrosion. Cov khoom kawg yuav tsum tau txais kev soj ntsuam tag nrho, suav nrog qhov ntev ntev (raws li GB / T 706-2016), cov khoom siv kho tshuab (tensile thiab cuam tshuam kev ntsuam xyuas), qhov zoo ntawm qhov chaw (kev ywj pheej los ntawm qhov tsis xws luag xws li tawg thiab folds), thiab tshuaj ntsuam xyuas muaj pes tsawg leeg.
Ntim thiab xa khoom
Cov ntaub ntawv tsim nyog tau muab tso ua ke los ntawm kev qhia tshwj xeeb thiab ntim nrog cov hlua khi lossis cov ntoo pallets, qhia meej meej rau kev tiv thaiv los nag thiab ya raws. Ua ntej ua zaub mov xa tuaj, daim ntawv pov thawj zoo uas qhia txog lub tshuab hluav taws xob, tus lej batch, cov khoom siv kho tshuab, thiab cov qauv siv yuav tsum suav nrog txhawm rau txhawm rau txheeb xyuas qhov tseeb.
Xaus
Cov txheej txheem ntau lawm rau carbon steel profiles yog ib qho kev fusion ntawm cov ntaub ntawv science, mechanical engineering, thiab kev tswj kom zoo. Los ntawm kev tswj xyuas qhov tsis zoo ntawm txhua theem, peb tuaj yeem ua tau zoo ua tau zoo -cov ntaub ntawv zoo uas ua tau raws li cov kev xav tau ntawm ntau hom kev lag luam, muab cov khoom siv txhim khu kev qha rau kev tsim kho vaj tse, kev tsim tshuab, thiab lwm yam. Nyob rau hauv lub neej yav tom ntej, nrog rau kev txhawb nqa ntawm ntsuab manufacturing technologies (xws li pov tseg thaum tshav kub kub rov qab thiab tsawg- carbon metallurgy), cov txheej txheem ntau lawm rau carbon steel profiles yuav txhim kho mus rau ntau dua efficiency thiab sustainability.
