CovERW (hluav taws xob kuj welded) yeeb nkabyog ua los ntawm txias ua ib tug steel sawb mus rau hauv ib tug cylindrical zoo. Cov npoo yog ces fused ua ke siv lub siab - zaus hluav taws xob tam sim no, ua tau zoo heev, tus nqi- cov yeeb nkab zoo uas tsis muaj cov khoom siv ntxiv.
Nws yog siv los thauj cov roj, nkev thiab lwm yam vapor-kua khoom. Nws tuaj yeem ua tau raws li ntau yam kev xav tau ntawm kev kub siab thiab qis, thiab ua lub luag haujlwm tseem ceeb hauv kev xa cov kav dej hauv ntiaj teb.
Dab tsi yog cov txheej txheem tsim khoom ntawm ERW Pipe?
Cov khoom siv raw yog steel kauj, yog unrolled thiab flattened. Qhov kawg ntawm lub kauj tshiab yog pob tw -welded rau tus Tsov tus tw ntawm lub kauj dhau los kom paub meej tias kev ua haujlwm tas mus li.
2. Ntug Kev Npaj thiab tsim
Ua ntej tsim, cov npoo ntawm cov sawb yog trimmed los yog milled kom paub meej cov dav dav. Lub sawb ces dhau los ntawm kev sib tsoo thiab yob, uas khoov cov hlau mus rau hauv ib lub voj voog maj mam.
3. Vuam
Raws li cov yeeb nkab qhib npoo raug nias ua ke, siab - zaus hluav taws xob tam sim no dhau los ntawm cov khoom. Qhov tsis kam mus rau qhov tam sim no sai heats cov npoo rau lawv cov ntsiab lus melting, thiab nyem cov hlua khi lawv ua ke, fusing lawv mus rau hauv ib qho chaw ruaj khov, longitudinal seam.
4. Deburring thiab kho cua sov
Lub casing los yog milling cov cuab yeej yog siv los tshem tawm cov welds tshaj nyob rau hauv thiab sab nraud ntawm cov yeeb nkab, tsim ib tug du nto. Tom qab ntawd, qhov chaw welded tau dhau los ntawm lub tshuab cua sov induction kom normalize qhov vuam- txo qhov kev ntxhov siab sab hauv thiab tsim kom muaj qhov sib xws, muaj zog microstructure.
5. Qhov loj me thiab txiav
Cov yeeb nkab mus los ntawm cov txheej txheem kawg ntawm sizing rolls kom paub meej meej roundness, straightness, thiab meej txheej kab. Ib tug ya pom ces txiav cov yeeb nkab txuas mus rau hauv tus neeg qhov ntev.
6. Kev tshuaj xyuas thiab kev sim
Cov kav dej tau raug kuaj xyuas nruj, suav nrog kev ntsuas ultrasonic thiab electromagnetic los xyuas qhov kev ncaj ncees ntawm cov vuam, ua raws li kev ntsuas hydrostatic siab kom ntseeg tau tias lawv tsis xau hauv siab.
4. Tsis tas li ntawd, qhov teeb meem geometric xws li ellipticity thiab qhov tsis sib xws ntawm cov yeeb nkab phab ntsa tuab feem ntau yog tshwm sim los ntawm qhov tsis ruaj khov dov txoj kev siab, hnav ntawm cov txheej txheem, thiab qhov tsis tsim nyog loj. Cov yam ntxwv no ua rau tsis tsim nyog cov yeeb nkab roundness thiab me me kam rau ua, uas nyob rau hauv lem cuam tshuam rau kev sib txuas thiab kev teeb tsa ntawm cov yeeb nkab fittings.
5. Kev khawb ntawm qhov chaw feem ntau yog tshwm sim los ntawm kev sib txhuam ntawm txoj siv hlau thiab cov khoom siv thaum lub sij hawm pub mis thiab tsim cov txheej txheem, thiab lawv tuaj yeem ua rau lub ntsej muag ncaj ncees thiab tiv thaiv kev ua haujlwm ntawm cov yeeb nkab lub cev.
Txheej Txheem Tswj Cov Ntsiab Lus
Yuav luag txhua qhov tsis xws luag ntawm ERW steel kav yog tsim los ntawm peb yam tseem ceeb: cov khoom siv raw khoom tsis zoo, tsis tsim nyog sib piv ntawm cov txheej txheem tsis raug, thiab tsis yog - cov txheej txheem ua haujlwm. Txhawm rau tiv thaiv kev tsim cov khoom tsis zoo thiab ua kom cov khoom ruaj khov zoo, cov txheej txheem tag nrho - kev tswj cov txheej txheem yuav tsum tau ua nyob rau hauv tag nrho cov txheej txheem tsim khoom.
1. Ua ntej ntawm tag nrho cov, nruj kev soj ntsuam cov khoom nyob rau hauv lub Hoobkas yog lub hauv paus barrier rau kev tswj kom zoo. Cov neeg tsim khoom yuav tsum tau kuaj xyuas cov tshuaj muaj pes tsawg leeg, cov khoom siv kho tshuab, thiab qhov chaw ntawm cov hlau coils, tshem tawm cov ntaub ntawv raw nrog ntau dhau impurities, rusty nto, tawg, los yog tsis sib xws, yog li tshem tawm cov kev pheej hmoo zoo ntawm qhov chaw.
2. Qhov thib ob, tus qauv ua ntej- kev kho cov hlau strips yog qhov tseem ceeb tshaj plaws. Cov npoo ntawm cov hlau strips yuav tsum raug txiav kom meej thiab ntxuav kom huv si kom tshem tawm cov burrs, oxides, roj stains thiab nplai, kom ntseeg tau tias cov npoo vuam yog du, tiaj tus thiab tsis sib xws, kom ua tau raws li qhov siab - zaus cua sov thiab ua kom tiav metallurgical fusion.
3. Thib peb, qhov tseeb dynamic txuam ntawm cov tub ntxhais vuam tsis yog qhov tseem ceeb tshaj plaws. Cov kws tshaj lij yuav tsum tau kho cov vuam tam sim no, khiav ceev thiab extrusion siab nyob rau hauv lub sij hawm raws li cov yeeb nkab cov khoom specifications thiab steel qib, los tiv thaiv weld spalling vim overheating los yog tsis tiav fusion tshwm sim los ntawm tsis txaus tshav kub input, li no kom ntseeg tau lub ntom thiab uniform microstructure ntawm weld seam.
4. Plaub, kev tswj xyuas cov txheej txheem txias yog tsim nyog. Tom qab vuam, qhov ruaj khov thiab qeeb txias yuav tsum tau khaws cia kom tsis txhob muaj qhov cuam tshuam ntawm qhov seem ntawm kev ntxhov siab thiab cov kab mob khaub thuas uas tshwm sim los ntawm qhov kub thiab txias.
Tsis tas li ntawd, nws yog ib qho tsim nyog los tsim kom muaj ib lub sijhawm tiag tiag - kev saib xyuas cov cuab yeej siv sijhawm thiab kev saib xyuas tsis tu ncua. Tsis tu ncua calibrations ntawm txoj kev rolls, sizing rolls thiab siab - zaus vuam cov cuab yeej yuav tsum tau ua kom tshem tawm qhov zoo fluctuations los ntawm cov khoom aging thiab parameter deviations.
Los ntawm kev ua haujlwm ntawm tus txheej txheem thoob plaws tag nrho cov txheej txheem, tiag tiag - lub sijhawm ntsuas ntsuas, thiab kev saib xyuas nruj, qhov tsis xws luag ntawm ERW steel kav tuaj yeem txo tau zoo, tag nrho cov txiaj ntsig ntawm cov khoom tiav tuaj yeem txhim kho tau zoo, thiab qhov ruaj khov thiab txhim khu kev qha zoo ntawm cov kav hlau hlau tsim nyog rau siab - cov qauv kev lag luam tuaj yeem lav tag nrho.
