Electric Resistance Welded steel kav yog tsim los ntawm ib tug tas mus li txoj kev thiab welding txheej txheem nyob rau hauv uas steel sawb maj mam shaped mus rau hauv ib tug cylindrical daim ntawv thiab welded raws ib tug longitudinal seam. Ntawm tag nrho cov ntaub ntawv koom nrog hauv cov txheej txheem no, kub -rolled carbon steel coils yog cov khoom siv raw. Cov coils no muab lub hauv paus hlau uas txiav txim siab cov yeeb nkab lub zog, qhov ruaj khov, thiab weldability. Vim tias ERW cov kav dej tau tsim ncaj qha los ntawm cov hlau tsis muaj hlau ntxiv, qhov zoo thiab qhov tshwj xeeb ntawm cov kub -rolled carbon steel coil muaj kev cuam tshuam ncaj qha rau kev tsim khoom thiab kev ua haujlwm kawg ntawm cov yeeb nkab.
Kub-rolled carbon steel coils yog tsim nyob rau hauv steel mills los ntawm dov rhuab steel slabs ntawm kub. Cov txheej txheem tso cai rau cov khoom loj ntawm cov hlau yuav tsum tau tsim nrog tswj thickness, dav, thiab txhua yam khoom. Thaum tsim tawm, cov coils no raug thauj mus rau cov chaw tsim khoom siv yeeb nkab uas lawv tsis muaj coiled, leveled, thiab pub rau hauv cov mills los tsim ERW kav. Kev ntseeg siab ntawm cov khoom siv raw no ua rau nws yog cov khoom siv dav siv hauv nruab nrab thiab me me welded yeeb nkab ntau lawm.
Specification Range ntawm Kub-Rolled Carbon Steel Coils
Hom Dimensional Range rau ERW Pipe Manufacturing
| Parameter | Hom kab mob | Qhov tseem ceeb hauv ERW Production |
|---|---|---|
| Coil thickness | 1.5-20 hli | Txiav cov yeeb nkab phab ntsa thickness |
| Coil dav | 600-1600 hli | Txiav txim siab txoj kab uas hla |
| Coil hnyav | 10-30 tons | Influences ntau lawm efficiency |
| Inner coil txoj kab uas hla | Nyob ib ncig ntawm 610 mm | Standard rau coil tuav khoom |
Qhov tshwj xeeb ntawm qhov kub ntawm -kho cov pa roj carbon steel coils yog tsim los ua kom haum raws li cov kev cai tsim ntawm ERW yeeb nkab ntau lawm kab. Coil thickness yog ncaj qha ntsig txog phab ntsa thickness ntawm cov yeeb nkab tiav. Piv txwv li, coils nrog thickness ntawm kwv yees li 1.5 hli thiab 6 hli feem ntau yog siv rau lub teeb structural kav los yog cov kua dej thauj mus los, thaum thicker coils mus txog 20 hli yuav siv tau rau hnyav structural daim ntaub ntawv los yog nruab nrab - siab pipelines.
Qhov dav ntawm cov hlau coil txiav txim siab qhov ncig ntawm cov yeeb nkab uas tuaj yeem tsim tau. Los ntawm kev xaiv ib lub kauj nrog qhov dav uas tsim nyog, cov tuam txhab tsim khoom tuaj yeem tsim cov kav dej nrog cov txheej txheem tshwj xeeb. Vim tias ERW cov kav dej yog tsim los ntawm lub tiaj tiaj tiaj, kev tswj xyuas qhov dav dav dav yog qhov tseem ceeb los xyuas kom meej qhov kev sib raug zoo ntawm ntug thaum vuam.
Coil hnyav kuj cuam tshuam rau kev ua haujlwm ntawm cov yeeb nkab ntau lawm. Heavier coils tso cai rau kev ua haujlwm txuas ntxiv mus ntev dua yam tsis muaj kev hloov pauv ntau zaus, uas txhim kho kev tsim khoom. Cov txheej txheem coil puab diameters yog tsim los kom phim cov cuab yeej siv hauv steel mills thiab cov yeeb nkab tsim cov nroj tsuag, kom ntseeg tau tias cov ntaub ntawv du mus thoob plaws hauv cov txheej txheem ntau lawm.
Qhov Yuav Tsum Tau Zoo ntawm Kub-Rolled Carbon Steel Coils
Yam khoom thiab qhov yuav tsum tau ua
| Yam Khoom Zoo | Kev xav tau | Kev cuam tshuam rau Pipe Quality |
|---|---|---|
| Deg mob | Dawb los ntawm cov kab nrib pleb thiab hnyav | Xyuas kom ruaj khov welding |
| Thickness kam rau ua | Tswj nyob rau hauv qhov txwv nqaim | Khaws qhov tseeb qhov tseeb |
| Ntug mob | Smooth thiab precisely trimmed | Txhawb txhim khu kev qha weld seam tsim |
| Mechanical sib xws | Uniform lub zog thiab ductility | Enables ruaj khov txheej txheem |
Qhov zoo ntawm cov kub- dov carbon steel coils ua lub luag haujlwm tseem ceeb hauv kev txiav txim siab kev ntseeg siab ntawm ERW kav. Surface condition yog ib qho ntawm thawj yam uas tau soj ntsuam thaum lub sij hawm tshuaj xyuas cov khoom raw. Txawm hais tias ib txheej nyias ntawm oxide nplai muaj ntau nyob rau hauv cov kub - dov steel, ntau dhau, tawg, lossis khawb tuaj yeem tsim teeb meem thaum vuam. Nto irregularities nyob ze ntawm lub strip npoo yuav cuam tshuam nrog hluav taws xob tiv thaiv cua sov los yog txo lub zog ntawm weld seam.
Thickness kam rau ua kuj yuav tsum nruj tswj. Thaum steel sawb nkag mus rau hauv txoj kev tsim ntawm ERW cov kab ntau lawm, nws dhau los ntawm ntau lub yob sawv ntsug uas maj mam ua cov khoom siv rau hauv ntu ntu ntu. Yog hais tias lub coil thickness sib txawv heev raws nws qhov ntev los yog dav, txoj kev siab thov los ntawm cov yob yuav ua tsis ncaj. Qhov no tuaj yeem ua rau ovality lossis hloov pauv hauv cov yeeb nkab phab ntsa tuab, txo qhov raug qhov tseeb.
Ntug mob yog ib qho tseem ceeb tshwj xeeb vim hais tias cov npoo ntawm cov hlau sawb yog cov cheeb tsam uas yuav tsum tau koom ua ke thaum vuam. Cov npoo no yuav tsum huv, ncaj, thiab tsis muaj burrs. Precise trimming ntawm cov npoo npoo tso cai rau cov yob sib sau ua ke cov npoo kom raug ua ntej vuam theem, uas yuav pab tsim ib qho kev sib txuam weld seam nrog cov khoom ruaj khov.
Mechanical sib xws ntawm tag nrho cov kauj yog qhov tseem ceeb. Kev hloov pauv ntawm cov khoom siv zog los yog cov ductility tuaj yeem ua rau tsis sib xws thaum lub sijhawm tsim. Yog tias qee qhov ntawm cov sawb muaj zog dua los yog tsis muaj zog dua li lwm tus, cov yeeb nkab tuaj yeem tsim kev sib txawv los yog cov duab tsis zoo thaum tsim khoom.
Kev cuam tshuam ntawm ERW Kev Tsim Txheej Txheem
Kub-rolled carbon steel coils cuam tshuam rau theem tsim ntawm ERW yeeb nkab tsim nyob rau hauv ntau txoj kev. Cov txheej txheem tsim pib thaum cov hlau sawb maj mam khoov mus rau hauv cov duab cylindrical los ntawm kev sib sau ua ke. Txhua yob sawv ntsug siv lub zog tswj kom rov ua dua lub sawb thaum tuav qhov tseeb qhov tseeb.
Hlau nrog zoo ductility thiab sib npaug txhua yam khoom tso cai rau du deformation yam tsis muaj cracking los yog ntau tshaj springback. Yog tias cov hlau hnyav dhau los yog nkig, nws tuaj yeem tiv thaiv kev tsim thiab tsim cov pob txha tawg. Hloov pauv, cov hlau uas muag muag heev tuaj yeem deform ntau dhau, ua rau cov yeeb nkab tsis ruaj khov.
Lub uniformity ntawm lub kauj kuj cuam tshuam rau kev ruaj ntseg ntawm txoj kev tsim. Cov tuab tuab thiab cov khoom siv kho tshuab ua kom ntseeg tau tias txhua ntu ntawm cov sawb coj zoo sib xws thaum dhau los ntawm kev sib sau yob. Qhov kev ruaj ntseg no yog qhov tseem ceeb rau kev tswj cov kav dej tsis tu ncua thiab cov phab ntsa thickness raws tag nrho qhov ntev ntawm cov yeeb nkab.
Thaum lub sij hawm siab - vuam zaus, cov npoo ntawm cov yeeb nkab tsim tau rhuab los ntawm hluav taws xob tsis kam thiab nias ua ke los tsim cov khoom sib txuas. Kev huv huv thiab kev ua haujlwm ntawm cov hlau saum npoo muaj feem cuam tshuam li cas hluav taws xob tam sim no ntws los ntawm cov khoom siv. Kub-rolled carbon steel coils nrog huv qhov chaw thiab tswj muaj pes tsawg leeg tso cai rau cua sov kom ruaj khov thiab pab tsim muaj zog weld seams.
Qhov tseem ceeb ntawm Kub-Rolled Coils hauv ERW Pipe Applications
Kub- dov carbon steel coils tseem yog cov khoom siv tseem ceeb rau ERW yeeb nkab ntau lawm vim tias lawv muaj qhov zoo sib npaug ntawm kev tsim khoom thiab kev ua haujlwm ntawm cov khoom siv. Lawv muaj nyob rau hauv ib tug ntau yam ntawm thicknesses thiab widths tso cai rau cov yeeb nkab manufacturers tsim cov kav dej haum rau ntau daim ntawv thov, nrog rau kev tsim kho, kav dej hauv nroog, tshuab tshuab, thiab lub zog infrastructure.
Kev sib xyaw ua ke ntawm kev tswj cov tshuaj muaj pes tsawg leeg, cov khoom siv kho tshuab ruaj khov, thiab cov lus qhia meej meej kom ntseeg tau tias kub -rolled coils tuaj yeem tsim kev ntseeg siab thiab welded rau hauv siab - cov kav dej zoo. Nrog rau niaj hnub steelmaking technologies xws li nruam casting, tswj dov, thiab advanced coil soj ntsuam systems, qhov zoo ntawm kub -rolled carbon steel coils tseem txhim kho.
Raws li kev xav tau thoob ntiaj teb rau kev tsim kho vaj tse thiab cov kav dej txuas ntxiv mus ntxiv, lub luag haujlwm ntawm kub -rolled carbon steel coils hauv ERW yeeb nkab tsim khoom tseem ceeb. Lawv cov kev ua tau zoo thiab kev hloov pauv tau muab lub hauv paus rau kev tsim cov kav dej uas ua tau raws li cov kev xav tau ntawm ntau yam haujlwm engineering.
