Peb feem ntau ntseeg hais tias ib tus cwj pwm txiav txim siab cov khoom 'zoo heev, cov ntsiab lus txiav txim siab cov khoom' zoo zoo, nrog rau tag nrho cov REALISTIC, EFFICIENT AND INNOVATIVE pab pawg ntsuj plig rauTuam Tshoj Tube thiab Galvanized yeeb nkab, Insisting tshaj lub high-zoo tiam kab kev tswj thiab kev cia siab rau cov neeg muab kev pab, peb tau ua peb cov kev daws teeb meem los muab peb cov neeg siv khoom siv cov khoom pib pib thiab tsis ntev tom qab muab kev pabcuam ua haujlwm.Tiv thaiv kom muaj kev sib raug zoo nrog peb lub zeem muag, peb txawm tias tam sim no innovate peb cov khoom lag luam teev ntau lub sij hawm kom tau raws li cov kev xav tau tshiab thiab ua raws li cov qauv tshiab ntawm kev lag luam hauv Ahmedabad.Peb npaj txhij mus rau lub ntsej muag thaj tsam qhov teeb meem thiab ua qhov kev hloov pauv kom nkag siab ntau qhov muaj peev xwm hauv kev lag luam thoob ntiaj teb.
Metallurgical zog ntawm cov khoom
Longitudinal submerged arc welded kav yog tsim los ntawm steel daim hlau, thaum kauv welded kav yog tsim los ntawm kub dov coils.Cov txheej txheem kub-dov strip unit dov txheej txheem muaj ntau qhov zoo thiab muaj cov txheej txheem metallurgical muaj peev xwm kom tau txais cov khoom zoo ntawm cov yeeb nkab kab hlau.Piv txwv li, qhov tso zis tso zis yog nruab nrog lub tshuab dej txias kom ceev cov cua txias, uas tso cai rau kev siv cov khoom siv qis qis kom ua tiav cov qib tshwj xeeb lub zog thiab qhov kub thiab txias toughness, yog li txhim kho cov weldability ntawm cov hlau.Txawm li cas los xij, qhov system no tsis tshua muaj nyob rau hauv steel sheet ntau lawm cov nroj tsuag.Cov ntsiab lus ntawm cov hlau (carbon sib npaug) ntawm cov coils feem ntau qis dua li cov qib zoo sib xws ntawm cov hlau phaj, uas kuj tseem txhim kho cov weldability ntawm kauv welded kav.
Nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias, vim hais tias cov kauv welded yeeb nkab coil dov kev taw qhia tsis yog perpendicular mus rau cov kev taw qhia ntawm cov yeeb nkab steel axis (nws pinch tov nyob ntawm lub kauv lub kaum sab xis ntawm cov yeeb nkab steel), thaum ncaj seam steel yeeb nkab steel phaj dov. kev taw qhia perpendicular mus rau cov kev taw qhia ntawm cov yeeb nkab steel axis, thiab yog li, cov khoom siv kauv welded yeeb nkab yog zoo dua li ncaj seam steel yeeb nkab tawg tsis kam.
Vuam txheej txheem
Los ntawm cov txheej txheem welding, kauv welded yeeb nkab thiab ncaj seam steel yeeb nkab vuam txoj kev yog tib yam, tab sis ncaj seam welded yeeb nkab yuav inevitably muaj ntau ding weld, yog li txoj kev pheej hmoo ntawm vuam tsis xws luag yog loj heev, thiab cov residual kev nyuaj siab ntawm vuam. nyob rau hauv lub ding weld yog loj, lub weld hlau feem ntau nyob rau hauv ib tug peb-txoj kev kev nyuaj siab lub xeev, ua rau muaj peev xwm ntawm cracking.
Ntxiv mus, raws li cov txheej txheem submerged arc vuam, txhua qhov vuam yuav tsum nyob ntawm qhov pib arc thiab arc extinguishing, tab sis txhua qhov ncaj seam welded yeeb nkab nyob rau hauv welded annular seam, tsis tuaj yeem ua tiav qhov xwm txheej, yog li tej zaum yuav muaj ntau qhov vuam tsis xws ntawm lub arc. tua hluav taws.
