Say WCB, sakey a carbon steel casting material ya ontutumbok ed ASTM A216 Grade WCB, et ondalan ed sakey ya standardized heat treatment process pian nadampot so nakaukolan iran mekanikal a kablian, dimensional stability, tan resistensya ed thermal stress. Diad leksab et walay detalyadon deskripsion na kaslakan ya heat treatment workflow parad WCBYD7A1X-16 Butterfly Valvecastings:
1. Panpainit
- Gagala: Pian nabawasan so thermal gradients tan naprebentaan so pan-crack legan na ontumbok ya high-temperature treatment.
- Proseso: Saray casting et kalkalnan papainitan ed sakey a kontroladon hurnoan ya anggad temperaturan 300-400°C (572-752°F).
- Saray Manunan Parametro: Say heating rate et mansiasiansia ed 50-100°C/oras (90-180°F/oras) pian naseguro so parehon temperatura.
2. Austenitizing (Normalizing)
- Gagala: Pian magmaliw ya parepareho so microstructure, napino so kabaleg na bukel, tan natunaw iray carbide.
- Proseso:
- Saray casting et papainit ed temperaturan 890–940°C (1634–1724°F).
- Iyan ed sayan temperatura parad 1-2 oras kada 25 mm (1 pulgada) na kapal na seksion pian naseguro so kompleton pananguman na yugtan.
- Inpabetel ed ag-onkikiwas ya dagem (manpaparaan) ed temperatura na kuarto.
3. Panpaabeba
- Gagala: Pian naekal so nakekeraan ya stress, napaaligwas so inka-tough, tan napabiskeg so microstructure.
- Proseso:
- Kayari na i-normalize, saray castings et painit-init lamet ed temperature ya 590–720°C (1094–1328°F).
- Inbasa ed sayan temperatura parad 1-2 oras kada 25 mm (1 pulgada) na kapal.
- Palemewen ed dagem odino palemewen ed hurnoan ed kontroladon peles pian ag-onlesa so balon stress.
4. Inspeksyon Kayari na Panagtambal
- Gagala: Pian naseguro so panumbok ed saray estandarte na ASTM A216.
- Proseso:
- Mekanikal a panagsukimat (alimbawa, biskeg na panag-awit, biskeg na panag-ani, inka-malet).
- Microstructural analysis pian naseguro so inkapara tan anggapoy depekto.
- Saray dimensional checks pian nakumpirma so inkapekder kayari na heat treatment.
Saray Opsyonal ya Kundang (Espesipikon Kaso)
- Makaekal na Stress: Parad saray komplikadon geometriya, nayarin gawaen so kaaruman ya stress-relief cycle ed 600–650°C (1112–1202°F) pian naekal so nakekeraan ya stress manlapud panag-machine o panag-welding.
- Kontroladon Panagpabetel: Parad saray makapal ya seksion na casting, nayarin usaren so mas matantan ya panagpabetel (alimbawa, panagpabetel na hurno) legan na panag-temper pian napaaligwas so ductility.
Saray Manunan Ikonsidera
- Atmospera na Hurnoan: Neutral odino medyo man-oxidize ya atmospera pian ag-onkupas so carbon.
- Pankakasakey na Temperatura: ±10°C ya tolerance pian naseguro so pareparehon resulta.
- Dokumentasyon: Sigpot a pakasubaybayan na saray parametro na heat treatment (panaon, temperatura, cooling rates) parad kalidad na kaseguroan.
