Puas yog carbon steel yeeb nkab yog welded steel yeeb nkab?

Carbon steel yeeb nkab tsis yog welded steel yeeb nkab.Carbon steel yeeb nkab yog hais txog cov khoom tshwj xeeb ntawm cov yeeb nkab steel yog carbon steel, uas yog hais txog hlau-carbon alloy nrog cov ntsiab lus carbon Wc tsawg dua 2.11%.Ntxiv nrog rau cov pa roj carbon, nws feem ntau muaj me me ntawm silicon, manganese, phosphorus, sulfur thiab lwm yam impurities.thiab lwm cov kab seem seem.Tsis tas li ntawd, cov yeeb nkab carbon steel no muaj ntau yam kev siv, feem ntau yog siv hauv kev tsim kho, txuas hniav, railways, tsheb, nkoj thiab ntau yam kev lag luam kev lag luam.

Carbon steel kav yuav muab faib ua carbon steel welded kav thiab carbon steel seamless kav raws li cov txheej txheem tsim.

Cov pa roj carbon steel welded kav yuav muab faib ua peb hom: ncaj seam submerged arc welded steel kav, kauv welded steel kav, thiab high-frequency ncaj seam welded steel kav raws li txoj kev tsim ntawm weld seam.
Longitudinal welded yeeb nkab: Lub vuam yog nyob rau hauv txoj kab ncaj nraim, yog li nws yog hu ua ncaj seam welded yeeb nkab.
Kauv welded yeeb nkab: Lub vuam seam yog nyob rau hauv ib tug kauv zoo, uas yog hu ua kauv vuam.

Peb txoj kev vuam muaj lawv tus kheej qhov zoo thiab qhov tsis zoo, thiab qhov twg yuav tsum siv yog nyob ntawm tus qauv tsim.Cov pa roj carbon steel welded steel yeeb nkab tuaj yeem siv tau rau ntau qhov chaw, xws li cov khoom siv dej thiab cov dej ntws, cov haujlwm piling, cov kav dej phwj tuaj, cov roj thiab cov roj xa mus, cov ncej thiab lwm yam haujlwm.Txoj kev vuam tam sim no ntawm carbon steel welded steel yeeb nkab feem ntau yog ob sab submerged arc vuam.Txoj kev vuam no muaj kev ua haujlwm siab, siab vuam zoo thiab du nto.

Carbon steel seamless yeeb nkab ntau lawm txoj kev:

Cov pa roj carbon steel seamless kav tau muab faib ua ob hom: kub dov (extruded) seamless steel kav thiab txias-draw (dov) seamless steel kav vim lawv cov txheej txheem tsim khoom sib txawv.Cold drawn (dov) raj tau muab faib ua ob hom: cov raj puag ncig thiab cov raj tshwj xeeb.

1. Kub dov (extruded) carbon steel seamless steel yeeb nkab: round tube billet → cua sov → tho → peb-yob ntoo khaub lig dov, nruam dov los yog extrusion → raj tshem tawm → sizing (los yog txo) → txias → straightening → dej ntsuas ( los yog tsis pom kev) → cim → cia

Cov khoom siv raw rau dov seamless carbon steel yeeb nkab yog round tube billet, thiab round tube embryo yuav tsum tau txiav los ntawm lub tshuab txiav kom loj hlob billets nrog ntev li ntawm 1 meter, thiab thauj mus rau lub cub tawg los ntawm conveyor siv.Billet yog noj rau hauv lub qhov cub kom sov, qhov kub thiab txias yog li 1200 degrees Celsius.Cov roj yog hydrogen lossis acetylene.Kev tswj qhov kub thiab txias hauv qhov cub yog qhov teeb meem tseem ceeb.Tom qab lub raj puag ncig tawm ntawm lub qhov cub, nws yuav tsum tau tho los ntawm lub siab piercer.Feem ntau, qhov ntau dua piercer yog lub khob hliav qab yob piercer.Hom piercer no muaj kev ua haujlwm siab, cov khoom lag luam zoo, loj perforation txoj kab uas hla nthuav dav, thiab tuaj yeem hnav ntau hom hlau.Tom qab piercing, lub round tube billet yog successively hla-dov, nruam dov los yog extruded los ntawm peb yob.Tom qab extrusion, lub raj yuav tsum tau muab tshem tawm rau sizing.Sizing los ntawm high-speed rotary cone laum qhov rau hauv lub billet los tsim ib lub raj.Sab hauv txoj kab uas hla ntawm cov yeeb nkab steel yog txiav txim siab los ntawm qhov ntev ntawm lub taub sab nraud ntawm lub laum me ntsis ntawm lub tshuab sizing.Tom qab cov yeeb nkab steel yog qhov loj, nws nkag mus rau hauv cov cua txias ntauwd thiab txias los ntawm txau dej.Tom qab cov yeeb nkab steel yog txias, nws yuav ncaj.Tom qab straightening, cov yeeb nkab steel raug xa mus rau cov hlau tsis haum (lossis kuaj hydraulic) los ntawm txoj siv conveyor rau kev kuaj pom qhov tsis zoo.Yog tias muaj cov kab nrib pleb, npuas thiab lwm yam teeb meem hauv cov yeeb nkab steel, lawv yuav raug kuaj pom.Tom qab kev soj ntsuam zoo ntawm cov kav dej steel, yuav tsum tau xaiv phau ntawv nruj.Tom qab kev soj ntsuam zoo ntawm cov yeeb nkab steel, pleev xim rau cov naj npawb, specification, ntau lawm batch tooj, thiab lwm yam nrog cov xim.Thiab hoisted mus rau hauv lub warehouse los ntawm crane.

2. Cold drawn (dov) carbon steel seamless steel yeeb nkab: round tube dawb paug → cua sov → perforation → taub hau → annealing → pickling → oiling (tooj liab plating) → multi-pass txias kos duab (txias dov) → khoob raj → tshav kub kho → Straightening → Hydrostatic test (qhov tsis pom kev) → cim → warehousing
