S235JR kauv welded yeeb nkab txheej txheem tso cai dab tsi?
Piv rauncaj seam kav, cov txheej txheem kauv vuam tso cai rau kev siv cov kav dej loj dua thiab ua kom cov yeeb nkab muaj zog. CovS235JR kauv welded yeeb nkabtxheej txheem siv ib qho txuas ntxiv, tus nqi - ua tau zoo, thiab muaj txiaj ntsig zoo los tsim cov kav loj - txoj kab uas hla, xav tau cov khoom siv tsawg dua piv rau lwm cov txheej txheem.
Cov txheej txheem ua tau zoo no yog qhov zoo tshaj plaws rau kev tsim cov loj- txoj kab uas hla, tuab- cov kav dej uas muaj ntau qhov ntev, tsim cov kav dej uas muaj zog thiab ruaj khov uas haum rau cov dej, roj, kev thauj mus los ntawm cov roj av, thiab kev tsim kho.
Qhov txawv ntawm S235JR ERW yeeb nkab thiab S235JR kauv yeeb nkab yog dab tsi?
ERW welded yeeb nkabmuaj cov txheej txheem tsim khoom yooj yim, kev ua haujlwm siab ntau lawm, tus nqi qis, thiab kev loj hlob sai.Kauv welded yeeb nkabyog ib tug coiled steel yeeb nkab ua los ntawm steel sawb coils. Nws feem ntau yog tsim los ntawm sov extrusion thiab welded los ntawm tsis siv neeg ob -hlau ob -sided submerged arc vuam txheej txheem. Lub zog ntawm kauv welded yeeb nkab feem ntau siab dua li ntawm ERW welded yeeb nkab.
Dab tsi yog qhov zoo ntawm S235JR kauv welded kav?
Kauv welded yeeb nkabyog ib cov yeeb nkab uas tsim los ntawm spirally forming steel coils rau hauv ib qho tshwj xeeb zoo. Piv nrog rau cov kav hlau ncaj ncaj, nws muaj ntau yam zoo, nrog rau kev tiv thaiv corrosion ntau dua, siab dua - qhov kub thiab txias zog, thinner phab ntsa thickness (piv rau lwm hom yeeb nkab), thiab txo cov nqi tsim khoom vim muaj cov txheej txheem tsim tau zoo.
S235JR kauv welded yeeb nkab ua li cas?
Kauv welded yeeb nkab yog tsim los ntawm unrolled thiab flattened steel coils. Lub flattened steel sawb yog nias rau hauv lub tog raj kheej ntawm txoj kab uas xav tau siv lub kaum sab xis. Sab hauv thiab sab nraud submerged arc vuam seals cov kauv weld seam. Submerged arc welding (SAW) thev naus laus zis yog siv los tsim cov kav dej welded. Ib qho txheej txheem raug raws li hauv qab no: Ua ntej, cov hlau kauj yog unrolled thiab txiav kom tshem tawm cov npoo tsis sib xws. Tom qab ntawd, steel sawb yog dov mus rau hauv ib tug kauv zoo. Tom ntej no, sab hauv thiab sab nraud kauv vuam yog ua. Thaum kawg, weld seam undergoes kev tswj kom zoo thiab kev ntsuam xyuas kev ncaj ncees.
Txoj kev no ua rau kev tsim cov yeeb nkab ntu ntawm cov kab sib txawv thiab qhov ntev, yog li txhim kho nws cov practicality nyob rau hauv cov ntawv thov kev lag luam.
S235JR kauv yeeb nkab yog dab tsi?
Kauv cov kav dejtuaj yeem ua los ntawm ntau yam khoom siv raw, xws li carbon steel, galvanized steel, stainless hlau, aluminium, thiab coated hlau. S235JR yog ib qho qis- cov pa roj carbon steel uas muaj cov pa roj carbon tsawg (feem ntau Tsawg dua lossis sib npaug li 0.22%) thiab nruj tswj hwm cov khoom tsis zoo xws li phosphorus thiab sulfur. Cov yam ntxwv ntawm qhov sib xyaw ua ke tso cai rau nws tswj tau qee theem ntawm lub zog thaum tseem muaj qhov zoo weldability thiab toughness.
