WCB, piny ma juyubu ku cuma ma julwongo ni carbon steel ma lubu ASTM A216 Grade WCB, ukadhu kud i yore mi lyethu ma juyiko maber pi nwangu piny ma mitere, bedo maber, man bedo maber pa lyethu. Piny eni utiye gonyo lembe matuc pa tic mi lyethu pi WCBYD7A1X-16 Butterfly Valvecastings:
1. Lyethu con
- Pi bero: Mi jwigo thermal gradients man mi juku cracking i saa mi tic ma tek.
- Yore: Castings juyike moth moth i furnace ma jugwoko maber nitundo i lyethu ma romo 300–400°C (572–752°F).
- Lembe ma pire tek: Wel mi lyethu jugwoko i 50–100°C/sawa (90–180°F/sawa) mi neno nia lyethu opokere marom.
2. Austenitizing (Normalizing)
- Pi bero: Mi ketho microstructure obed marom, yiko dit pa kodhi, man jwigo carbides.
- Yore:
- Castings juyike nitundu ikum lyethu pa 890–940°C (1634–1724°F).
- Jugwoko i lyethu eni pi 1-2 sawa pi 25 mm (1 inch) pa dul ma lac mi neno nia aloka loka pa dul eca utimere.
- Juyike i yamu ma oling (ma rwinyo) ni rwom pa lyethu mi ot.
3. Tempering
- Pi bero: Mi jwigo peko madong, medu tegu, man dwoko piny ma nok.
- Yore:
- I ngei dwoko piny, judwoko piny ma jucwalo ni piny ma lyeth pa 590–720°C (1094–1328°F).
- Juyike i lyethu eni pi 1-2 sawa pi 25 mm (1 inch) mi lac.
- Juyike i yamu nyoke juyike i furnace i kadhiri ma jugwoko maber pi jwigo peko manyen.
4. Neno ingey yath
- Pi bero: Ni ketho lembe ikum cik pa ASTM A216.
- Yore:
- Temo mi cuma (e.g., tego mi mako piny, tego mi yiko piny, tek pa piny).
- Lapor pa piny ma nok nok mi neno ni piny marom rom man bedo mbe pa peko.
- Nen pa dit pa piny pi ketho cing ikum bedo maber ingey lyethu.
Lembe ma jutimo (Case-Specific)
- Weko lworo: Pi geometries ma nya wange nya wange tek, jucopo timo lembe mukende ma nyayu peko i 600–650°C (1112–1202°F) ni kwanyu peko madong ikum tic ku cuma nyo welding.
- Kwero ma jugwoko: Pi thick-section castings, cooling rates ma nok (e.g. furnace cooling) jucopo tiyu kudu i saa mi tempering pi medo ductility.
Lembe ma pire tek
- Furnace Atmosphere: Yamu ma nyai nyo ma nyayu yamo manok pi juku decarburization.
- Kit lyethu marom: ±10°C bedo moth pi neno adwogi maber.
- Karatasi: Nwangu lembe ceke ma mako lyethu (saa, lyethu, kadhiri mi ngico) pi bedo ku genogen.
