Hlau cevkev tsim cov thev naus laus zis tau pib nrog kev nce ntawm kev tsim tsheb kauj vab, roj kev loj hlob nyob rau hauv thaum ntxov xyoo pua 19th, ob lub ntiaj teb ua tsov ua rog ships, boilers, aircraft tsim, tom qab lub thib ob ua tsov ua rog thermal fais boiler manufacturing, kev lag luam thiab yog li ntawd txoj kev loj hlob ntawm roj thiab roj drilling thiab kev thauj mus los, ua tau zoo tsav cov yeeb nkab steel kev lag luam nyob rau hauv txoj kev loj hlob ntawm hom, tawm los thiab zoo. Feem ntau steel yeeb nkab nyob rau hauv txoj kab nrog txoj kev sib dhos, muab faib ua seamless steel yeeb nkab thiab welded steel yeeb nkab ob hom, tam sim no tsuas yog los qhia welded steel yeeb nkab.
Welded steel yeeb nkab yog cov welded steel yeeb nkab, nws cov ntau lawm yog tias lub raj dawb paug (steel phaj thiab steel siv) nrog kev sib kis ntawm txoj kev tsim khoov thiab yob rau hauv qhov xav tau kev sib tshuam thiab qhov loj ntawm lub raj raj, thiab lwm yam. siv cov txheej txheem vuam sib txawv los vuam cov vuam thiab tau txais cov txheej txheem steel yeeb nkab. Piv nrog seamless steel yeeb nkab, welded yeeb nkab muaj cov yam ntxwv ntawm high precision, tshwj xeeb tshaj yog cov precision ntawm phab ntsa thickness, yooj yim lub ntsiab cov cuab yeej, me me txoj hauj lwm, nruam lag luam nyob rau hauv ntau lawm, saj zawg zog ntau lawm, ntau yam khoom ntawm chav tsev ces nyob rau.
Cov txheej txheem tsim khoom rau cov kav dej yuav muab faib ua: SSAW (Spirally Submerged Arc Vuam); LSAW (Longitudinous Arc Vuam); hluav taws xob tsis kam vuam (ERW) peb.
I. txheej txheem sib dhos ntawm kauv steel yeeb nkab yog kwv yees li hauv qab no
● Cov khoom siv raw ntawm kauv steel yeeb nkab yog sawb coil, vuam hlau thiab flux.
● Ua ntej tsim cov sawb tom qab leveling, txiav, npaj, ntxuav, kev thauj mus los thiab dabtsi yog khoov.
● Weld gap control device yog ua hauj lwm los xyuas kom meej tias qhov sib txawv weld raws li qhov yuav tsum tau vuam, thiab cov yeeb nkab txoj kab uas hla, staggered ntug thiab weld gap yog nruj me ntsis tswj.
● Tom qab txiav rau hauv ib lub yeeb nkab steel, txhua batch ntawm cov yeeb nkab steel taub hau peb los tuav cov kev soj ntsuam nruj ua ntej, xyuas cov khoom siv ntawm cov vuam, tshuaj lom neeg muaj pes tsawg leeg, melting mob, steel yeeb nkab nto zoo thiab tom qab kev tshuaj xyuas tsis zoo, xyuas kom meej tias cov yeeb nkab. ua cov txheej txheem tsim nyog, raug muab tso rau hauv ntau lawm.
Ob, ncaj seam submerged arc vuam yeeb nkab
Ncaj seam submerged arc welded yeeb nkab (LSAW) feem ntau siv phaj raws li cov khoom siv, los ntawm cov txheej txheem sib txawv, siv ob sab submerged arc vuam thiab tom qab vuam o thiab lwm yam txheej txheem los ua cov yeeb nkab welded.
Cov khoom tseem ceeb yog shaping tshuab, pre-bending tshuab, sib sau tshuab, pre-welding tshuab, expanding tshuab ces nyob rau. Lub caij no, muaj UO (UOE), RB (RBE), JCO (JCOE) thiab tom qab ntawd. Lub phaj nyob rau hauv cov pwm pwm yog thawj zaug nias rau hauv U duab, yog li nias rau hauv O zoo, thiab yog li sab hauv thiab sab nraud submerged arc vuam, vuam feem ntau yog nyob rau sab saum toj lossis tag nrho ntev ntawm qhov nthuav dav (Expanding) hu ua UOE welded yeeb nkab, tsis Expanding hu ua UO welded yeeb nkab. Lub phaj yog dov dabtsi yog khoov zoo li tus, ces sab hauv thiab sab nraud submerged arc vuam yog ua. Tom qab vuam, txoj kab uas hla yog RBE welded raj lossis RB welded raj yam tsis tau nthuav dav. Lub phaj yog tsim nyob rau hauv qhov kev txiav txim ntawm JcO-hom, thiab tom qab vuam, txoj kab uas hla yog nthuav mus rau JCOE welded yeeb nkab lossis JCO welded yeeb nkab yam tsis tau nthuav dav.
Peb, ncaj seam siab zaus welded yeeb nkab (ERW) yog qhov kub dov coil tom qab molding tshuab, siv cov hluav taws xob tshwm sim thiab cov nyhuv sib thooj ntawm cov zaus tam sim no, yog li lub sting ntawm lub raj yog rhuab thiab melted, nyob rau hauv qhov kev txiav txim ntawm extrusion. roller siab welding kom ncav cuag ntau lawm.
