Seamless ntawmERW steel yeeb nkabmuab faib ua geometric seamless thiab lub cev seamless.Geometric seamless ntawm ERW steel yeeb nkab yog tshem tawm sab hauv thiab sab nraud burrs.
Txij li cov qauv ntawm lub puab burr tshem tawm system thiab cov cuab yeej ntawm kev txhim kho tas mus li thiab zoo tag nrho, nruab nrab thiab loj txoj kab uas hla steel yeeb nkab hauv burr tshem tawm tau zoo deal.Tsis pub dhau lub burr tuaj yeem tswj tau hauv -0.2mm ~ + O.5mm li.Hais txog lub cev seamless weld microstructure sab hauv, muaj qhov sib txawv ntawm cov khoom siv hauv paus thiab qhov chaw vuam uas ua rau cov khoom siv tsis zoo, qhov yuav tsum tau ntsuas kom ua kom zoo ib yam thiab siv technology zoo ib yam.ERW steel yeeb nkab yog rau high-frequency vuam thermal txheej txheem thiab ua rau ib tug kub gradient, uas yog nyob ze ntawm lub ntug ntawm lub raj thiab tsim ib tug molten cheeb tsam, lub semi-molten cheeb tsam, overheating cov ntaub so ntswg, normalized cheeb tsam, cheeb tsam tsis tag nrho normalizing, tempering zones. ntawm lub cheeb tsam feature.Uas overheated cheeb tsam cov ntaub so ntswg vim soldering kub tshaj 1000℃, austenite grain loj hlob heev nyob rau hauv lub txias tej yam kev mob yuav tsim ib tug nyuaj thiab nkig ntxhib crystalline theem, nyob rau hauv tas li ntawd mus rau lub xub ntiag ntawm ib tug kub gradient yuav tsim welding kev nyuaj siab.Yog li, qhov tsim ntawm thaj chaw weld qis dua lub hauv paus hlau cov cuab yeej cuab tam ntawm qhov teeb meem yog los ntawm lub cev seamless weld kev kho cua sov txheej txheem uas siv cov khoom siv hluav taws xob hauv zos cov khoom siv hluav taws xob yuav ua rau thaj tsam weld yog rhuab rau AC3 (927.℃), ces 60m ntev, qhov ceev 20m / min thaum lub sij hawm cua txias, dej txias thaum tsim nyog.Txoj kev no yog siv los ua kom tiav qhov kev tshem tawm ntawm kev ntxhov siab, soften thiab refine lub koom haum los txhim kho HAZ mechanical zog lub hom phiaj.Tam sim no, lub ntiaj teb qib siab ERW chav tsev tau siv dav rau kev ua cov vuam tau txais txiaj ntsig zoo.Kev ua tau zoo tsis tuaj yeem sib cav tias tsis yog ERW yeeb nkab welds thiab weld coefficient ntawm 1, lub realization ntawm cov koom haum hauv cheeb tsam ntawm cov vuam thiab lub hauv paus hlau ntawm qhov sib tw.
