1. Kuzindikiritsa katundu
Dzina lazogulitsa: SAE / AISI 1020 Carbon Steel - Round / Square / Flat Bars
Khodi yamalonda ya Womic Steel: (ikani code yanu yamkati)
Fomu yobweretsera: Yotentha, yokhazikika, yotsekedwa, yokoka (yozizira) monga momwe tafotokozera
Zomwe zimagwiritsidwa ntchito nthawi zonse: ma shafts, mapini, zipilala, ma axles (zolimba), zida zomangira, tchire, zomangira, zida zamakina aulimi, zida zamphamvu zotsika.
2. Chidule / Chidule cha Ntchito
SAE 1020 ndi kalasi yotsika kwambiri ya kaboni, yopangidwa ndi chitsulo yomwe imagwiritsidwa ntchito kwambiri pomwe mphamvu zolimbitsa, kuwotcherera kwabwino komanso makina abwino amafunikira. Nthawi zambiri amaperekedwa m'malo otentha kapena ozizira ndipo amagwiritsidwa ntchito nthawi zambiri m'malo omwe aperekedwa kapena pambuyo pokonza zina (mwachitsanzo, kubisala, kutentha, kukonza makina). Womic Steel imapereka mipiringidzo 1020 yokhala ndi zowongolera zokhazikika ndipo imatha kupereka zina zowonjezera monga kukonza makina, kuwongola, kuumitsa zingwe komanso kugaya mwatsatanetsatane.
3.Mapangidwe Amtundu Wake (wt.%)
| Chinthu | Mulingo Wofananira / Wokwera (%) |
| Mpweya (C) | 0.18 - 0.23 |
| Manganese (Mn) | 0.30 - 0.60 |
| Silicon (Si) | ≤ 0.40 |
| Phosphorous (P) | ≤ 0.040 |
| Sulfure (S) | ≤ 0.050 |
| Mkuwa (Cu) | ≤ 0.20 (ngati yatchulidwa) |
4.Zofananira Zamakina
Makina amasiyanasiyana malinga ndi momwe amapangira (yotentha, yokhazikika, yokhazikika, yokokedwa). Miyezo yomwe ili m'munsiyi ndi yofanana ndi makampani; gwiritsani ntchito MTC pazinthu zotsimikizika zamakontrakitala.
Zotenthedwa / Zokhazikika:
- Kulimba kwamphamvu (UTS): ≈ 350 - 450 MPa
- Mphamvu zokolola: ≈ 250 - 350 MPa
- Kutalika: ≥ 20 - 30%
- Kulimba: 120 - 170 HB
Zozizira:
- Kulimba kwamphamvu (UTS): ≈ 420 - 620 MPa
- Mphamvu zokolola: ≈ 330 - 450 MPa
- Kutalika: ≈ 10 - 20%
- Kuuma: kwapamwamba kuposa kugudubuzika kotentha
5. Katundu Wakuthupi
Kachulukidwe: ≈ 7.85 g/cm³
Modulus of Elasticity (E): ≈ 210 GPA
Chiŵerengero cha Poisson: ≈ 0,27 - 0.30
Kutentha kwamafuta ndi kukulitsa: zofananira ndi zitsulo zotsika kaboni (onani matebulo a uinjiniya kuti muwerengere kamangidwe)
6.Chithandizo cha Kutentha & Kugwira Ntchito
Annealing: kutentha pamwamba pa masinthidwe osiyanasiyana, pang'onopang'ono ozizira.
Normalizing: yeretsani kamangidwe kambewu, onjezerani kulimba.
Kuzimitsa & Kutentha: kuchepetsedwa kupyolera-kuumitsa; vuto kuumitsa analimbikitsa.
Carburizing: wamba ku SAE 1020 pazida zolimba / zolimba pachimake.
Cold Working: kumawonjezera mphamvu, kumachepetsa ductility.
7. Weldability & Fabrication
Weldability:Zabwino. Njira zofananira: SMAW, GMAW (MIG), GTAW (TIG), FCAW. Preheat kawirikawiri sikufunika kwa makulidwe wamba; tsatirani ndondomeko zowotcherera (WPS) zazinthu zofunika kwambiri.
Brazing / Soldering:machitidwe okhazikika amagwira ntchito.
Kuthekera:Zabwino - 1020 makina mosavuta; makina ozizira okokedwa ndi mipiringidzo mosiyana ndi mipiringidzo annealed (zida ndi magawo kusinthidwa).
Kupanga / Kupinda:Ductility yabwino mu annealed state; malire opindika amadalira makulidwe ndi chikhalidwe.
8. Standard Mafomu, Makulidwe & Tolerances
Womic Steel imapereka mipiringidzo yamitundu yofananira. Miyeso yokhazikika yomwe ilipo mukafuna.
Mafomu operekera:
Mipiringidzo yozungulira: Ø6 mm mpaka Ø200 mm (magawo a mainchesi amadalira mphamvu ya mphero)
Mipiringidzo yayikulu: 6 × 6 mm mpaka 150 × 150 mm
Mipiringidzo yosalala / yamakona anayi: makulidwe ndi m'lifupi kuti ayitanitsa
Kudula mpaka kutalika, kuchekedwa, kapena kumapeto kwamoto; malo opanda pakati komanso mipiringidzo yomalizidwa yomwe ilipo.
Kulekerera & kumaliza pamwamba:
Kulekerera kumatsata kasitomala kapena miyezo yoyenera (ASTM A29/A108 kapena yofanana ndi ma shaft omaliza ozizira). Womic Steel imatha kupereka malo olondola (h9/h8) kapena kutembenuzira pakufunika.
9. Kuyendera & Kuyesa
Womic Steel imachita kapena ikhoza kupereka zowunikira ndi kuyesa zotsatirazi:
Mayeso okhazikika (ophatikizidwa pokhapokha atanenedwa):
Kusanthula kwa Chemical (spectrometric / wet chemistry) ndi MTC yowonetsa mawonekedwe enieni.
Kuyesa kwamphamvu (monga mwa dongosolo lachitsanzo logwirizana) - lipoti la UTS, YS, Elongation.
Kuyang'ana kowoneka ndi kutsimikizira kowoneka bwino (m'mimba mwake, kuwongoka, kutalika).
Mayeso olimba (zitsanzo zosankhidwa).
Zosankha :
Akupanga Kuyesa (UT) kwa zolakwika zamkati (100% kapena sampuli).
Kuyeza kwa Magnetic Particle (MT) kwa ming'alu yapamtunda.
Mayeso a Eddy-pano a zolakwika zapamtunda/pafupi ndi pamwamba.
Kuwunika kosawerengeka kosawerengeka komanso kuwunika kwa gulu lachitatu (ndi Lloyd's, ABS, DNV, SGS, Bureau Veritas, ndi zina).
MTC yathunthu ndi mitundu ya satifiketi ikafunsidwa (mwachitsanzo, masatifiketi amtundu wa ISO 10474 / EN 10204 ngati kuli koyenera).
10.Chitetezo Pamwamba, Packing & Logistics
Chitetezo cha pamwamba:Kupaka mafuta oletsa dzimbiri (muyezo), zipewa za pulasitiki zozungulira (ngati mukufuna), kulongedza zoletsa dzimbiri paulendo wautali wapanyanja.
Kulongedza:omanga m'mitolo ndi zingwe zitsulo, matabwa dunnage kunja; mabokosi amatabwa opangira mipiringidzo yolondola ngati pakufunika.
Chizindikiro / chizindikiro:mtolo uliwonse / kapamwamba kokhala ndi nambala ya kutentha, giredi, kukula, dzina la Womic Steel, ndi nambala ya PO monga momwe akufunira.
11.Quality Systems & Certification
Womic Steel imagwira ntchito pansi pa kasamalidwe kabwino kolembedwa (ISO 9001).
MTC ikupezeka pakutentha / gulu lililonse.
Kuwunika kwa chipani chachitatu ndi zivomerezo za gulu-magulu zitha kukonzedwa pa mgwirizano.
12.Magwiritsidwe / Ntchito Zofananira
General engineering: shafts, pins, studs and bolts (asanathe kutentha kapena kuumitsa pamwamba)
Zida zamagalimoto pazogwiritsa ntchito zosafunikira kapena ngati zida zoyambira pamagawo a carburized
Zigawo zamakina aulimi, zolumikizira, zida zamakina ndi zida
Kupanga kumafuna weldability wabwino ndi mphamvu zolimbitsa
13.Zopindulitsa za Womic Steel & Services
Kuthekera kwa chigayo cha mipiringidzo yotentha komanso yomaliza ozizira yokhala ndi zowongolera zolimba.
Labu yabwino m'nyumba yoyezetsa mankhwala ndi makina; MTC yoperekedwa pa kutentha kulikonse.
Ntchito zowonjezera: kugaya mwatsatanetsatane, kugaya mopanda pakati, kukonza makina, kuthira ma carburizing (kudzera mu ng'anjo za anzawo), ndi kulongedza akatswiri kuti atumize kunja.
Nthawi zotsogola zampikisano komanso chithandizo chapadziko lonse lapansi.
Timanyadira zathumakonda misonkhano, kufulumira kupanga mkombero,ndiglobal delivery network, kuwonetsetsa kuti zosowa zanu zenizeni zikukwaniritsidwa molondola komanso mwaluso.
