S355 Stainless Hlau Yeeb thiab Tube

S355N yog qib steel uas yog los ntawm kub-kuav los tiag uas tsis yog-alloy structural steel hauv European tus qauv EN 10025-2. Tus "S" sawv cev rau "cov qauv hlau", thiab tus lej "355" qhia tias nws qhov kev tawm dag zog tsawg kawg yog 355 MPa. Hom hlau no feem ntau siv rau hauv cov khoom siv thiab cov khoom siv hauv tsev, txuas hniav, nkoj thiab tshuab tsim khoom. S355N steel muaj qhov zoo weldability, plasticity thiab toughness, nrog rau siab tensile zog thiab durability. Nyob rau tib lub sijhawm, nws cov ntsiab lus qis carbon muab nws cov khoom txias txias zoo. Txhawm rau kom ntseeg tau tias cov khoom siv kho tshuab thiab tshuaj lom neeg muaj pes tsawg leeg ntawm cov khoom ua tau raws li qhov yuav tsum tau ua, thaum siv S355N steel, yuav tsum tau them nyiaj rau cov khoom xaiv, ua thiab siv raws li cov qauv tsim.S355 steel yeeb nkab muaj ntau qhov ntau thiab tsawg. , nrog rau puag ncig, square, thiab duab plaub. Nws tseem tuaj yeem ua rau ntau qhov sib txawv, xws li dub lossis galvanized, kom haum rau cov kev xav tau tshwj xeeb. Raws li ntau yam khoom siv, nws tuaj yeem siv rau ntau yam kev siv, xws li kev tsim vaj tsev, txuas hniav, thiab cov kav dej.

Kev tsim tshuab thiab txheej txheem ntawm S355N steel phaj feem ntau suav nrog cov kauj ruam hauv qab no:

1. Kev npaj cov khoom siv raw: Xaiv cov ntawv hlau uas ua tau raws li cov qauv tsim raws li cov khoom siv raw, suav nrog cov tshuaj muaj pes tsawg leeg, cov khoom siv kho tshuab thiab lwm yam ntsuas.

2. Smelting: Muab cov khoom nyoos xaiv rau hauv qhov cub kub kub rau smelting. Los ntawm cua sov thiab tswj qhov kub thiab txias hauv qhov cub, cov ntaub ntawv raw yog yaj tag thiab sib tov sib npaug.

3. Nruam casting: Ncuav cov hlau molten rau hauv lub tshuab nruam nruam, txias nws los ntawm cov crystallizer thiab tsim ib daim ntawv txuas ntxiv. Thaum lub sij hawm nruam casting txheej txheem, refining thiab deoxidation ntawm molten hlau tuaj yeem nqa tawm.

4. Kub dov: Lub nruam casting billet yog rhuab mus rau ib tug haum kub thiab dov los ntawm lub kub dov chav tsev kom maj mam txo cov thickness thiab kho qhov dav thiab ntev ntawm cov hlau phaj. Tom qab ntau dhau ntawm dov thiab txias, S355N steel daim hlau uas ua tau raws li qhov yuav tsum tau maj mam tau.

5. Hlau phaj txiav: Raws li cov neeg siv khoom xav tau, cov ntawv hlau tsim tau raug txiav rau qhov loj me.

6. Kev kho deg: Ntxuav thiab tshem tawm cov xeb ntawm qhov chaw ntawm cov hlau phaj kom ntseeg tau tias qhov chaw du thiab huv.

7. Kev soj ntsuam zoo: Tshawb xyuas cov tshuaj muaj pes tsawg leeg, cov khoom siv kho tshuab, qhov loj thiab cov tsos ntawm S355N steel phaj tiav kom paub tseeb tias cov khoom ua tau raws li tus qauv yuav tsum tau ua.

8. Ntim thiab xa khoom: Tom qab ntim, ntim thiab lwm cov txheej txheem, cov ntawv tsim nyog S355N steel yuav raug ntim thiab xa tawm los ntawm lub Hoobkas rau kev thauj mus los thiab siv.

Nws yuav tsum raug sau tseg tias cov txheej txheem tsim khoom tshwj xeeb thiab cov txheej txheem yuav txawv nyob ntawm cov tuam txhab sib txawv thiab cov txheej txheem khoom siv. Cov saum toj no tsuas yog qhia luv luv rau cov txheej txheem dav dav. Hauv kev tsim khoom tiag tiag, kev tswj hwm thiab kev hloov kho yuav tsum tau ua raws li cov qauv tsim nyog thiab cov kev cai.

Cov hauv qab no yog cov chaw lag luam tseem ceeb ntawm S355 steel phaj:

1. Kev tsim kho engineering: S355 steel phaj feem ntau yog siv rau hauv kev tsim vaj tsev, xws li txuas hniav, cov khoom thauj khoom ntawm cov tsev thiab cov qauv kev txhawb nqa. Nws lub zog siab thiab corrosion kuj ua rau nws zoo tagnrho rau nqa cov khoom loj.

2. Kev tsim khoom: S355 steel phaj yog tsim rau kev tsim cov khoom siv, tsheb qhov chaw, nkoj qhov chaw thiab lwm qhov chaw. Nws cov txheej txheem zoo heev thiab cov khoom siv kho tshuab tuaj yeem ua tau raws li qhov xav tau ntawm ntau yam haujlwm nyuaj.

3. Kev lag luam roj thiab kev lag luam roj: Hauv cov txheej txheem ntawm kev tshawb nrhiav roj thiab roj, kev rho tawm thiab kev thauj mus los, S355 steel daim hlau tau siv dav hauv cov chaw xws li roj av platforms, cov kav dej thiab cov tank cia. Nws zoo heev corrosion kuj thiab siab zog ua kom muaj kev nyab xeeb thiab txhim khu kev qha kev ua haujlwm ntawm cov chaw.

4. Aerospace kev lag luam: Kev siv S355 steel daim hlau hauv kev lag luam aerospace yog maj mam nce. Vim nws lub teeb yuag, siab zog thiab corrosion kuj, nws yog tsim rau kev tsim ntawm aircraft lug, cav qhov chaw thiab navigation systems.

5. Cua tsim hluav taws xob: Nrog txoj kev loj hlob sai ntawm kev lag luam cua zog, S355 steel daim hlau tau nce siv hauv cov khoom siv hluav taws xob cua. Nws lub zog muaj zog tuaj yeem tiv taus huab cua hnyav thiab cua tshuab siab, ua kom lub zog ua haujlwm ntev ntawm cov khoom siv cua.

Zuag qhia tag nrho, S355 steel phaj muaj dav daim ntawv thov kev cia siab nyob rau hauv ntau yam kev lag luam teb. Nrog rau kev nthuav dav ntawm kev lag luam hauv tsev thiab txawv teb chaws thiab kev loj hlob ntawm kev thov, S355 steel daim hlau muaj kev cia siab rau txoj kev loj hlob thiab yuav txuas ntxiv siv dav.
