Taw qhia
ERW steel yeeb nkab, luv luv rau Electric Resistance Welded steel yeeb nkab, yog ib qho ntawm cov kav dej siv dav tshaj plaws hauv cov roj thiab roj tsheb thauj mus los, cov khoom siv dej, kev siv cov qauv, thiab kev siv tshuab engineering. Piv nrog rau cov kav dej seamless thiab lwm yam welded yeeb nkab hom, ERW cov kav dej tau paub txog lawv qhov siab qhov tseeb, ruaj khov zoo, thiab cov nqi siv tau.
Kom nkag siab txog qhov zoo ntawm kev ua haujlwmERW cev, nws yog ib qho tseem ceeb los xyuas cov txheej txheem tsim khoom kom ntxaws. Txhua kauj ruam, los ntawm kev xaiv cov khoom siv raw mus rau qhov kev tshuaj ntsuam xyuas zaum kawg, ua lub luag haujlwm tseem ceeb hauv kev ua kom muaj kev ncaj ncees ntawm cov khoom siv, lub zog siv tshuab, thiab lub sijhawm ntev - kev cia siab rau kev pabcuam.
Raw Khoom Xaiv thiab Coil Npaj
Kev tsim cov ERW steel kav pib nrog kub -rolled steel coils. Cov coils no feem ntau yog tsim los ua raws li cov qauv xws li API 5L, ASTM A53, ASTM A106, EN 10219, lossis GB / T qauv, nyob ntawm daim ntawv thov zaum kawg.
Kev tswj cov tshuaj muaj pes tsawg leeg yog thawj qhov rooj zoo. Carbon, manganese, sulfur, phosphorus, thiab microalloying ntsiab yog nruj me ntsis tswj xyuas kom zoo weldability thiab mechanical kev ua tau zoo. Cov hlau coil nto yuav tsum huv si, tsis muaj xeb ntau dhau, laminations, lossis qhov tsis xws luag, vim tias cov kev tsis zoo no tuaj yeem cuam tshuam ncaj qha rau cov vuam zoo.
Ua ntej tsim, cov hlau kauj yog uncoiled, leveled, thiab trimmed. Ntug milling tuaj yeem siv los xyuas kom meej cov kab dav dav thiab cov npoo du, uas yog qhov tseem ceeb rau kev ruaj khov vuam thaum lub sij hawm siab - zaus vuam.
Txoj kev tsim: Los ntawm txoj kab ncaj nraim mus rau Tubular puab
Tom qab kev npaj, cov hlau sawb nkag mus rau hauv seem tsim. Los ntawm ib tug series ntawm txoj kev yob, lub tiaj tus strip yog maj khoov mus rau hauv ib tug puag ncig zoo. Tsis zoo li cov kav dej seamless, ERW cov kav dej cia siab rau cov yob txoj kev ua kom tiav qhov tseeb sab nraud thiab qhov sib npaug.
Cov txheej txheem tsim yog nce ntau dua li sai sai. Qhov no maj mam deformation txo qhov seem kev ntxhov siab thiab txo cov duab distortion. Kev sib raug zoo ntawm kev sib sau yob ua kom ntseeg tau tias cov npoo npoo sib ntsib raug ntawm qhov chaw vuam, nteg lub hauv paus rau qhov siab - zoo longitudinal weld seam.
Siab -Cov txheej txheem vuam zaus
Lub hauv paus ntawm ERW yeeb nkab raug tsim yog qhov siab -frequency resistance welding process. High- zaus hluav taws xob tam sim no yog siv rau cov npoo npoo, ua kom sov vim hluav taws xob tsis kam. Thaum cov npoo ncav cuag ib lub xeev yas los yog molten, lawv yog forged ua ke nyob rau hauv siab, ua ib tug khoom- xeev weld.
Tsis zoo li submerged arc vuam, ERW vuam tsis xav tau cov hlau muab tub lim. Lub vuam yog tsim los ntawm cov khoom siv hauv paus nws tus kheej, uas ua rau muaj cov qauv hlau ua homogeneous thaum tswj tau zoo.
Cov tsis tseem ceeb hauv cov txheej txheem no suav nrog vuam zaus, kev siv tam sim no, vuam ceev, thiab nyem lub zog. Kev tswj xyuas meej ntawm cov kev txwv no ua kom muaj kev nkag mus rau tag nrho thiab txo qhov tsis xws luag xws li tsis muaj fusion lossis vuam txias.
Weld Bead Tshem Tawm thiab Kev Kho Mob Hauv Online
Tom qab vuam, sab hauv thiab sab nraud weld hlaws raug tshem tawm siv cov cuab yeej scarfing. Cov kauj ruam no txhim kho cov yam ntxwv ntws sab hauv thiab sab nrauv, uas yog qhov tseem ceeb tshwj xeeb rau cov kav dej xa mus.
Ntau ERW cov kav dej ntau lawm suav nrog hauv online lossis offline intermediate -frequency annealing. Cov txheej txheem kev kho cua sov no txo cov kev ntxhov siab nyob hauv thaj chaw weld, ua kom cov qauv nplej, thiab txhim kho toughness thiab ductility. Kev kho kom zoo ua kom ntseeg tau tias thaj chaw weld nthuav tawm cov khoom siv sib piv los yog zoo dua li cov hlau hauv paus.
Sizing, Straightening, thiab txiav
Tom qab vuam thiab kev kho cua sov, cov yeeb nkab nkag mus rau hauv seem sizing. Ntau qhov sizing rolls yog siv los ua kom tiav cov kab npoo sab nraud kom haum rau thiab roundness. Straightening machines kho tej yam dabtsi yog khoov los yog ovality tshwm sim thaum lub sij hawm tsim thiab vuam.
Cov yeeb nkab yog txiav mus rau qhov ntev, feem ntau 6 meters lossis 12 meters, nyob ntawm seb cov neeg siv khoom xav tau. Txiav raug yog qhov tseem ceeb kom ua tau raws li qhov project installation cov qauv.
Kev tshuaj xyuas thiab kev tswj xyuas zoo
Kev tshuaj xyuas zoo yog ib feem tseem ceeb ntawmERW steel yeeb nkabntau lawm. Tsis yog-kev ntsuas kev puas tsuaj xws li kev kuaj ultrasonic thiab kev ntsuas tam sim no feem ntau siv los kuaj xyuas qhov tsis xws luag. Kev ntsuam xyuas hydrostatic siab kuj tseem tuaj yeem ua los xyuas qhov siab- muaj peev xwm ua tau.
Dimensional soj ntsuam, mechanical testing, thiab deg soj ntsuam xyuas kom ua raws li cov qauv siv. Tsuas yog cov kav dej uas dhau tag nrho cov theem tshuaj ntsuam xyuas tau pom zoo rau kev xa khoom.
Xaus
CovERW steel yeeb nkabmanufacturing txheej txheem yog ib tug heev automated thiab precisely tswj system. Los ntawm kev xaiv cov khoom siv raw mus rau kev soj ntsuam zaum kawg, txhua theem ua rau tag nrho qhov zoo thiab kev ntseeg siab ntawm cov yeeb nkab tiav. Kev nkag siab txog cov txheej txheem no pab cov neeg siv kawg txiav txim siab thaum xaiv ERW kav dej rau ntau yam kev siv engineering.
