RAJ MILL TSHUAB Cheebtsam
Lub ntsiab tseem ceeb
Lub raj zeb tshuab siv ntau daim ntawm cov cuab yeej tig mus ua hlau ua kom muaj zog kav. Txhua feem muaj txoj haujlwm tshwj xeeb hauv cov txheej txheem ntau lawm. Cov ntsiab lus tseem ceeb ntawm cov mill mills ua haujlwm ua ke kom paub tseeb tias cov khoom kawg tau raws cov qauv siab.
UNCOILER: Cov khoom no txau steel coils rau hauv lub raj zeb tshuab. Nws khaws cov kab ntau lawm txav tsis tau nres.
LEEM TSHUAB: Cov TSHUAB no flattens lub steel sawb. Nws tshem tawm khoov thiab ua rau cov hlau du ua ntej tsim.
Shearing thiab pob tw-Welder: Cov cuab yeej no txiav cov hlau sawb thiab weld xaus ua ke. Cov kauj ruam no pab ua kom tau cov khoom lag luam tas mus li.
Accumulator: Cov khoom siv no khaws cov hlau ib daim thiab ua kom nruj nro. Nws pab lub raj zeb tshuab khiav zoo.
Txoj kev sib sau thiab Sizing Mill: chais hauv tshooj no duab rau hauv ib puag ncig lossis square yeeb nkab. Lawv kuj tswj hwm phab ntsa tuab thiab lub taub.
Vuam chav tsev : No feem koom nrog cov npoo ntawm cov hlau sawb siv high-zaus induction induction induction induction induction induction induction induction induction induction induction induction induction induction induction. Nws tsim muaj zog, cov yeeb nkab.
Flying cut-off: Qhov no pom txiav cov yeeb nkab tiav rau qhov ntev ntev thaum cov kab ntau lawm ua kom txav mus.
Cov Txheej Txheem Ua Si : Cov khoom siv no ncaj, smooths, thiab kho cov yeeb nkab nto. Nws npaj cov yeeb nkab rau siv.
Cov tshuab ntim: Cov tshuab no pob thiab tiv thaiv cov kav dej tiav rau kev cia khoom thiab xa khoom.
Nco tseg: Kev saib xyuas ib txwm ntawm txhua cov cuab yeej siv, xws li tshuaj xyuas cov yob thiab cov chav vuam, pab tiv thaiv kom tsis txhob raug thiab ua kom cov steel raj khiav zoo.
Rolling Mill Role
Lub pob zeb dov rau yog ib qho tseem ceeb tshaj plaws ntawm lub raj zeb tshuab. Nws siv cov yob muaj zog los khoov thiab cov xim hlau txaij ua lub raj. Tus qauv tsim thiab qhov zoo ntawm cov txiv ntoo no cuam tshuam qhov loj, cov duab, thiab saum npoo ntawm cov yeeb nkab. Cov txheej txheem zoo thiab du thaj chaw ntawm cov chais pab tiv thaiv khawb thiab ua kom cov yeeb nkab puag ncig.
Lub rolling zeb tswj lub phab ntsa thickness thiab txoj kab uas hla ntawm cov yeeb nkab.
High zoo rollers tiv thaiv tshav kub thiab hnav, uas ua kom cov khoom siv ua haujlwm ntev dua.
Kev tu xyuas kom zoo thiab ua kom raws li cov xuab zeb uas tsis muaj kev pab tsis txhob muaj teeb meem tsis xwm yeem lossis cov kav dej tsis sib xws.
Lub Rolling Mill txoj kev ua tau zoo cuam tshuam rau qhov ceev thiab zoo ntawm tag nrho cov txheej txheem ntau lawm.
Ib lub zeb kom huv-khaws cia kom sawv daws kom ua kom cov hlau ua kom cov kav hlau ua kom cov kav dej ua kom tau cov kav dej nrog qhov ntev thiab muaj zog Welds. Cov khoom siv no txhawb kev tsim khoom tau txais txiaj ntsig zoo thiab muaj txiaj ntsig zoo.
Cov txheej txheem tseem ceeb hauv Raj Zeb Ntau Lawm
Uncoiling thiab Ncaj Ncees
Raj zeb ntau lawm pib nrog uncoiling thiab ncaj. Cov neeg ua haujlwm muab cov hlau chev ntawm lub uncoiler. Lub uncoiler txav tus hlau txaij rau hauv kab ntawm lub nrawm. Cov cav tov nrog cov tshuab hluav taws xob muaj zog thiab ua txoj haujlwm no. Piv txwv li, ib qho tsis muaj feem xyuam yuav tuav cov coils mus txog 6 tons. Nws tuaj yeem txav cov sawb sai li 50 meters ib feeb. Lub kauj yog feem ntau 1000 rau 1250 millimeters dav.
Tom qab uncoiling, tus leveling tshuab flattens cov hlau txaij. Cov tshuab no yuav siv tshem tawm khoov thiab Warps. Nws siv chais ua kom cov sawb tiaj thiab du. Pinch rollers pab coj sawb rau theem. Cov txheej txheem kuj txiav tawm ntawm lub taub hau thiab tus tw ntawm txoj hlua khi. Qhov no tshem tawm tej ntu kev puas tsuaj. Taub qab vuam koom nrog cov xaus ntawm cov coils sib txawv. Qhov no ua rau ib kab txaij ntev ntev rau ntau lawm.
Nco tseg: Cov kauj ruam no xav tau los ntawm cov cai tswj kev lag luam. Lawv ua kom cov steel sawb yog tiaj, ncaj, thiab muaj cov npoo du. Qhov no yog qhov tseem ceeb rau kev ua cov kav dej zoo nrog cov kev txwv nruj.

Txoj kev sib txuas thiab vuam
Cov kauj ruam tom ntej yog tsim thiab vuam. Rollers khoov lub tiaj tus hlau txaij rau hauv lub raj. Txhua cov menyuam khoov cov sawb me ntsis ntxiv. Tsis ntev, cov sawb ua ib puag ncig lossis square raj. Cov kauj ruam no tswj lub raj ntawm cov duab thiab phab ntsa tuab. Nws yog ib qho tseem ceeb rau lub raj lub zog muaj zog thiab ua tau zoo.
Tus Vuam cov txheej txheem koom nrog cov npoo ntawm lub raj. Feem ntau cov raj mills siv cov vuam zoo. Cov qauv no ua kom cov npoo ceev ceev thiab nias lawv ua ke. Qhov no ua rau lub ntsej muag sib luag. Weld leeg yog txawv ntawm cov raj. Yog li, Vuam Vuam yuav tsum yog txoj cai. Zoo vuam pab lub raj kom muaj kev ntxhov siab thiab siab.
High zaus vuam (HFW) yog txoj hauv kev los koom nrog cov raj.
Raj tsim ua rau lub raj muaj zog dua tab sis tsis muaj zog dua.
Weld seam yuav tsum tau kuaj xyuas kom muaj zog thiab ua tau zoo.
Tswjhwm zoo siv cov sensors thiab cov koob yees duab los saib Weld. Cov neeg ua haujlwm siv lasers thiab cov cuab yeej kho qhov muag los kuaj cov raj ntawm cov raj. Lawv kuj siv ultrasonic thiab eddy kev ntsuam xyuas kom pom cov teeb meem zais. Cov tshev no pab kom tus weld muaj zog thiab lub raj dawb los ntawm cov tsis sib haum.
Tswv yim: cov zaub thiab cov vuam chav yuav tsum yog txoj kab kom zoo. Zoo raws li lowers tsis txaus siab thiab ua kom lub raj ntawm txoj cai.
Sizing thiab xov
Tom qab vuam, lub raj mus rau sizing thiab xov. Sizing rollers txhim kho lub raj ntawm lub cheeb thiab kev sib tw. Kauj ruam no kho cov kev hloov pauv ntawm vuam thiab sib sau ua ke. Lub raj yuav tsum ua kom tiav txoj cai nruj rau qhov loj me, phab ntsa tuab, thiab ncaj. Machine Ntawm no tuaj yeem tuav Taus Taus kom nruj li 0.02 millimeters.
Tiav suav nrog ncaj, txiav, thiab kho qhov saum npoo. Lub tshuab ncaj yuav siv tawm txhua qhov khoov rau sab laug hauv lub raj. Cov ya tawm txiav-tawm pom txiav cov raj rau qhov ntev thaum cov kab tsiv. Cov neeg ua haujlwm lossis tshuab kuaj cov raj rau cov khawb av rau khawb lossis dents. Qee cov hlab tau txais kev kho ntxiv xws li txheej lossis polishing los ua kom lub ntsej muag zoo dua.
Sizing chais paub tseeb tias lub raj yog qhov loj me thiab cov duab.
Ncaj machine cia lub raj ncaj rau kev siv yooj yim.
Txiav machine ua kom huv, txawm tias xaus rau txhua lub raj.
NCO TSEG: Kev tswj cov txiaj ntsig zoo thiab kev saib xyuas tsis tu ncua thiab khaws cov khoom khiav zoo. Thaum lub zeb loj siv ua kom zoo nkauj thiab tswj, muaj tsawg dua qhov tsis xws luag, thiab cov khoom siv ntev dua.
Cov kauj ruam tseem ceeb hauv Raj zeb ntau hlob, ua kom ncaj, kev sib tw, thiab ua tiav-ua haujlwm ua ke ua cov cai ua haujlwm nyuaj. Txhua kauj ruam yuav tsum ua kom zoo zoo kom paub tseeb tias lub raj kawg yog muaj zog, muaj tseeb, thiab npaj rau cov haujlwm nyuaj.

Seamless Tube Mill
Seamless cov mills ua kav dej uas tsis muaj weld seam. Cov txheej txheem pib nrog cov khoom siv sib hloov hlau billet. Lub zeb weats thiab tho lub billet, ces qaws nws rau hauv lub raj hollow. Txoj kev no, cov kav dej seamless yog qhov muaj zog thiab tuaj yeem ua kom muaj zog ntau ntxiv-txog 20% ntau tshaj li welded kav dej. Seamless tubes tseem sib ntaus xeb zoo dua vim tias lawv tsis muaj lub weld cheeb tsam.
Seamless cov raj mills siv hauv cov roj, roj, thiab lub zog teb. Cov haujlwm no xav tau cov kav dej uas tuaj yeem siv siab thiab kub. Cov txheej txheem yuav siv sijhawm ntev dua thiab siv ntau lub zog, yog li zaum ua tus nqi ntau dua li welded kav.
Vuam Txoj Kev
Cov Mills Raj siv txoj kev sib tw sib txawv, tab sis zaus ua hluav taws xob zoo tshaj plaws yog qhov ntau tshaj plaws rau welded kav dej. Txoj kev no suav nrog ob qho kev sib cuag thiab kev sib tw vuam. Kev siv hluav taws xob ntau zaus ua haujlwm nrog ntau cov hlau, khiav nrawm, thiab siv tsawg dua lub zog. Nws tseem ua rau muaj qhov kub me me-cuam tshuam, yog li tsis muaj dabtsi yog khoov.
Lwm txoj kev vuam, xws li tiv thaiv vuam, kuj yog siv hauv kev ua raj. Cov Hluav Taws Xob Hluav Taws Xob (ERW) yog nrov rau kev ua cov yeeb nkab welded ntau zaus. Nws ua haujlwm zoo rau cov hlau hlau, hlau hlau, hlau hlau, thiab almoy. Tab sis ERW yog qhov zoo tshaj plaws rau cov kav dej nrog thinner phab ntsa. Cov kav dej ua rau txoj kev no yog pheej yig thiab ua haujlwm zoo rau feem ntau siv.
Tswv yim: Xaiv txoj kev vuam vuam pab txuag nyiaj thiab ua kom cov kav dej khov,.
