- Thickness Control & Thinning: Thaum lub sij hawm tsim, cov khoom ntawm lub crown yog stretched. Thickness thinning yog qhov nyuaj tshaj plaws. Kev suav meej ntawm cov tuab tuab thiab cov txheej txheem tsim yog yuav tsum tau ua kom ntseeg tau tias qhov thinnest point tseem ua tau raws li qhov yuav tsum tau muaj zog. Multi-point thickness ntsuas yog yuav tsum tau.
- Cov Cuab Yeej Cuab Yeej Cuab Yeej & Kev Tswj Kub Kub: Tsis yog- cov cua kub tsis sib xws thaum lub sij hawm kub kub ua rau kev sib sau tsis sib xws, muaj kev ntxhov siab ntau, los yog tawg. Qhov kub thiab txias -tswj cua sov rauv yog qhov tseem ceeb.
- Tooling & Khoom: Hemispherical tuag yog sib sib zog nqus nrog loj curvature, yuav tsum tau high manufacturing precision. Siab heev -tonnage hydraulic presses nrog cov rooj loj yog xav tau.
- Tswj Kev Sib Tw Thaum Tshav Kub Kho Mob: Lub taub hau loj hemispherical muaj qhov cuam tshuam los ntawm lawv tus kheej qhov hnyav lossis kev txhawb nqa tsis raug thaum kho cua sov, yuav tsum tau tsim tshwj xeeb rau cov menyuam txaj lossis cov khoom siv.
- Khoom Khoom: Yuav tsum tau zoo heev kub plasticity thiab cuam tshuam toughness. Cov ntaub ntawv muaj xws li SA516 Gr.70 (siab hlab ntsha carbon steel), SA387 Gr.11/22 (chrome-molybdenum steel), thiab ntau yam stainless hlau (xws li, SA240 304/316).
Core Sib piv Table
Stainless hlau thiab carbon steel hemispherical phaj xaus muaj qhov sib txawv tseem ceeb hauv kev tsim khoom, kev ua haujlwm, thiab kev siv. Cov lus hauv qab no qhia meej txog lawv cov kev sib txawv tseem ceeb
| Sib piv Dimension | Stainless hlau Hemispherical phaj kawg | Carbon Steel Hemispherical phaj kawg |
|---|---|---|
| 1. Core Performance | Zoo corrosion kuj tiv thaiv oxidizing ib puag ncig, ntau cov kua qaub, alkalis, thiab ntsev daws. Qib siab huv, yooj yim los ntxuav. | Mechanical zog zoo, siab zog thiab toughness. Tsis zoo corrosion kuj, nquag xeb, yuav tsum tau tiv thaiv txheej. |
| 2. Cov nqi khoom siv | Siab heev. Alloying ntsiab (Ni, Cr, Mo) ua tus nqi feem ntau 3-8 zaug siab dua los yog ntau tshaj li carbon steel. | Tsawg. Qhov tseem ceeb raw khoom tus nqi kom zoo dua, kev lag luam dav dav - lub hom phiaj xaiv. |
3. Cov txheej txheem ntau lawm txawv
| Sib piv Dimension | Stainless hlau Hemispherical phaj kawg | Carbon Steel Hemispherical phaj kawg |
|---|---|---|
| • Kev tsim | Nyiam Txias Txias Forming (tshwj xeeb tshaj yog rau cov qib austenitic zoo li 304/316). Tsis txhob siab -kub oxidation thiab "sensitization" (carbide nag lossis daus). Yog kub- nias, yuav tsum tau tiv thaiv huab cua los yog tom qab pickling. | Feem ntau yog siv Kub Press Forming. Cov cua kub siab tshaj 900℃txo qhov deformation tsis kam, txuag xovxwm tonnage, thiab yog tus nqi nyiam- txoj kev zoo. |
| • Kev kho cua sov | Cov kev cai nruj dua thiab nyuaj. - Austenitic Stainless Steel (304/316): Feem ntau Cov Tshuaj Annealing (cua sov rau 1050-1150℃tom qab txias txias) los kho corrosion kuj, txo kev ntxhov siab, thiab txhim kho ductility. - Duplex Stainless Steel (2205): Yuav tsum tau tshuaj Annealing & quenching kom ua tiav ob qhov zoo tshaj plaws - theem piv thiab cov khoom. |
Cov txheej txheem cuam tshuam yooj yim dua. - Lub Hom Phiaj Tseem Ceeb: Kev Nyuaj Siab Kev Nyuaj Siab los yog normalizing & Tempering kom tshem tawm cov kev ntxhov siab uas seem, txhim kho microstructure, thiab rov ua kom tawv. - Kub: Feem ntau nyob rau hauv 600-900℃ntau yam. |
| • Kev kho saum npoo | Tseem ceeb. Pickling & Passivation yog yuav tsum tau tshem tawm nplai (tom qab kub sib sau) los yog fabrication contaminants (tom qab txias forming) thiab tsim ib tug ntom chromium oxide txheej rau saum npoo, uas yog qhov tseem ceeb rau nws corrosion kuj. | xaiv tau. Feem ntau cuam tshuam nrog sandblasting lossis txhaj tshuaj blasting, feem ntau los muab qhov chaw tsim nyog rau kev pleev xim tom ntej lossis los tiv thaiv- txheej txheej. |
| • Vuam | Xav tau. Yuav tsum tau tswj cov cua sov input, txuam cov hlau muab tub lim, thiab ntsuas zoo li backside purging los tiv thaiv degradation ntawm corrosion kuj nyob rau hauv weld cheeb tsam. | Mature thiab kuj yooj yim txheej txheem. Siv qhov sib piv qis - hydrogen electrodes los yog muab tub lim. |
Kev piav qhia ntxaws txog cov txheej txheem tseem ceeb sib txawv
Kev xaiv ntawm kev tsim kub yog qhov tseem ceeb
- Carbon Steel: Kub nias yog qhov kev xaiv thawj zaug. Qhov kub thiab txias txo nws cov yield zog, ua kom yooj yim deformation, thiab siv cov theem transformation los ua kom zoo dua cov qauv nplej.
- Stainless Hlau: Txias nias yog nyiam kom tsis txhob "sensitization" (Rau austenitic stainless hlau, nyob rau hauv 450-850℃ntau yam ua rau carbon los ua ke nrog chromium, tsim chromium carbides thiab ua rau chromium depletion ntawm grain ciam teb, uas yuav ua rau intergranular corrosion). Yog tias qhov kub nias yog qhov tsim nyog (rau cov phaj tuab), kev ua kom txias sai sai los ntawm kev nkag siab ntau yam lossis siv cov cua tiv thaiv yuav tsum tau ua.
Lub hom phiaj ntawm kev kho cua sov yog txawv kiag li
- Kev kho cua sov Carbon Steel: Lub hom phiaj tseem ceeb yog "Kev Txhim Kho Cov Khoom Siv Hluav Taws Xob".
- Stainless Steel Thaum tshav kub kub kho (Kev daws teeb meem Annealing): Lub hom phiaj tseem ceeb yog "Restoring Corrosion Resistance". Nws redissolves carbides rau hauv austenitic matrix thiab "locks" lawv nyob rau hauv cov khoom tov los ntawm ceev ceev txias.
Qhov tsim nyog ntawm Kev Kho Hniav yog Ntiaj Teb Sib nrug
- Rau stainless hlau, pickling thiab passivation tsis yog ib kauj ruam kom zoo nkauj; nws yog cov txheej txheem tseem ceeb uas muab nws cov corrosion{0}}resistant lub neej. Yog tias tsis muaj txheej txheej passive, stainless hlau qhov kev tiv thaiv corrosion yog qhov cuam tshuam loj heev.
Kev Xaiv Cov Khoom Siv Kev Txiav Txim Siab
Thaum xaiv, ua raws li cov logic no:
- Kev txiav txim siab tseem ceeb: Nruab nrab thiab ib puag ncig: Yog tias qhov nruab nrab yog dej, chav dej, huab cua, lossis tsis yog - roj corrosive, carbon steel (+ tiv thaiv txheej) yog qhov kev xaiv pheej yig.
- Yog tias Corrosion lossis Hygiene Requirements muaj: Stainless hlau yuav tsum tau xaiv. Cov qib tshwj xeeb (304, 316L, Duplex, thiab lwm yam) xav tau kev txiav txim siab ntxiv raws li qhov nruab nrab (tshwj xeeb tshaj yog cov ntsiab lus chloride), qhov kub thiab txias, thiab qib kev ntxhov siab.
- Tus nqi vs. Kev Lag Luam Hauv Lub Neej-tawm: Txawm hais tias stainless hlau muaj kev nqis peev ntau dua, nws cov kev saib xyuas - pub dawb, ntev - cov yam ntxwv ntawm lub neej yuav muab tag nrho cov nqi ntawm cov tswv cuab zoo dua. Cov pa roj carbon steel xav tau kev saib xyuas tsis tu ncua thiab txheej txheej rov ua dua tshiab.
