Chitsulo cha Womic – Mayankho a Chitoliro Chosapanga Dzimbiri cha 347H Chogwira Ntchito Kwambiri

1. Chidule cha Nkhaniyi

Chitoliro cha chitsulo chosapanga dzimbiri cha 347H ndi chitsulo chosapanga dzimbiri cha austenitic chokhazikika ndi niobium chomwe chimadziwika ndi mphamvu zake zotentha kwambiri, kuthekera kowongoleredwa bwino, komanso kukana dzimbiri pakati pa granular. Kuwonjezera kwa niobium (Nb) kumawonjezera mphamvu yokwera ndikuletsa chromium carbide kugwa m'malire a tirigu, zomwe zimapangitsa kuti chisamve bwino.

2.Kapangidwe ka Mankhwala (Kawirikawiri)

3. Katundu wa Makina ndi Kutupa

Katundu wa Makina (ASTM A213):

- Mphamvu Yokoka ≥ 515 MPa

- Mphamvu Yotulutsa ≥ 205 MPa

- Kutalikitsa ≥ 35%

5. Njira Yopangira

1. Zipangizo Zopangira: Ma billets achitsulo ovomerezeka ochokera ku mafakitale am'nyumba ndi apadziko lonse lapansi

2. Kuzungulira Kotentha: Ma billets amatenthedwa kufika pa 1150–1200°C, amabowoledwa ndikuzunguliridwa kuti machubu akuluakulu kapena okhuthala akhale ndi khoma.

3. Chojambula Chozizira: Chojambula chozizira chodutsa maulendo angapo kuti chikhale cholondola komanso chomaliza pamwamba

4. Kutentha: Kuthira madzi mu 980–1150°C, kuzimitsa madzi mwachangu kuti achepetse kutsika kwa mpweya wa carbide

5. Kuwotcherera: Njira za GTAW (TIG), PAW, ndi SAW, pogwiritsa ntchito waya wodzaza wa ER347 kuti ukhazikike; njira zotsukira kumbuyo zilipo

6. Kumaliza Pamwamba: Kusakaniza, kusuntha (HNO₃/HF), ndi kupukuta kwamakina (Ra ≤ 0.2µm mukapempha)

7. Kuyang'anira: 100% RT (kuyesa kwa radiography) kwa ma welds; ultrasound, hydrostatic, PMI, kuyeza dzimbiri pakati pa granular ngati pakufunika.

6. Chitsimikizo ndi Kuwongolera Ubwino

Mapaipi achitsulo chosapanga dzimbiri a Womic Steel a 347H ali ndi ziphaso zotsatirazi:

- ISO 9001:2015

- PED 2014/68/EU

- AD2000 W0

- Khodi ya Boiler ndi Pressure ya ASME

Gulu lililonse limayesedwa mwamphamvu, kuphatikizapo:

- Mayeso a makina (kukakamiza, kukhudza, kuphwanyika, kuphulika)

- Mayeso a dzimbiri (IGC pa ASTM A262)

- Kuyesa kosawononga (UT, RT, Eddy current)

- Kuyang'anira miyeso ndi kutsata kwathunthu

7. Minda Yofunsira

Chitoliro cha chitsulo chosapanga dzimbiri cha 347H chimagwiritsidwa ntchito kwambiri mu:

- Kupanga Mphamvu: Zotenthetsera, zotenthetsera, mapaipi akuluakulu a nthunzi m'malo opangira mphamvu zotentha zosafunikira komanso zosafunikira kwambiri

- Mphamvu Yotentha ya Dzuwa: Matanki osungiramo kutentha a mchere wosungunuka (450–565°C), omwe agwiritsidwa ntchito bwino m'mapulojekiti ku China konse (Yumen, Haixi)

- Petrochemical: Machubu a ng'anjo, ma reactor ogwiritsira ntchito madzi (osagonjetsedwa ndi malo a H₂-H₂S-H₂O)

- Ndege: Mapayipi otulutsa utsi wa injini ndi mapaipi operekera mpweya wa turbine (ogwira ntchito mpaka 850°C)

- Zosinthira kutentha: Zoziziritsa kutentha kwambiri ndi mapaipi m'mafakitale oyeretsera ndi m'madzi

8. Nthawi Yotsogolera Kupanga

- Machubu Opanda Msoko (Makulidwe Okhazikika): Masiku 15–25

- Miyeso Yapadera/Mapaipi Okhuthala a Khoma: Masiku 30–45

- Maoda Akuluakulu: Kulemera kopitilira matani 3,000 pamwezi kumatsimikizira kutumiza mwachangu ngakhale pakafunika nthawi yofunikira

9. Kulongedza ndi Kukonza Zinthu

Womic Steel imapereka ma phukusi otetezeka komanso osinthika:

- Mabokosi a Matabwa Oyenera Kuyenda M'nyanja kapena Mabatani a Chitsulo

- Kudula Molondola

- Kukonza Ulusi ndi Kutsiriza Kumaliza

- Kusonkhanitsira zowotcherera (zipiko ndi zigongono)

- Kupanga mwamakonda pa zojambula

 

11. N’chifukwa Chiyani Muyenera Kusankha Chitsulo cha Womic?

- Labu Yofufuza ndi Kupititsa Patsogolo Yamkati

- Kupereka zinthu zopangira mokhazikika kumatsimikizira kuti nthawi yoperekera zinthuzo ndi yochepa.

- Zaka makumi ambiri zokumana nazo pakupanga zitsulo, makamaka mu zitsulo zotentha kwambiri

- Kulondola kwathunthu ndi zikalata zosonyeza kuti zipangizo zopanikizika zikutsatira malamulo

- Wopereka njira imodzi yopezera, kukonza, ndi kutumiza kunja makina a mapaipi achitsulo chosapanga dzimbiri

Kuti mudziwe zambiri zaukadaulo, mitengo, ndi mitengo ya mapulojekiti apadera, funsani Womic Steel lero. Tili okonzeka kuthandizira zosowa zanu za mapaipi ogwira ntchito bwino kwambiri molondola, mwachangu, komanso mwachilungamo.

Sankhani Womic Steel Group ngati mnzanu wodalirika waMachubu achitsulo chosapanga dzimbirindi ntchito yabwino kwambiri yotumizira. Takulandirani Funso!
