WCB, kabhoni simbi yekukanda zvinhu inoenderana neASTM A216 Giredhi WCB, inopinda yakamisikidzwa yekurapa kupisa maitiro kuti iwane inodiwa michina zvivakwa, dimensional kugadzikana, uye kuramba kushushikana kwekupisa. Pazasi pane tsananguro yakadzama yeyakajairwa kupisa kupisa kuyerera kweWCBYD7A1X-16 Butterfly Valvecastings:
,1. Preheating,
- ,Chinangwa: Kudzikisa kupisa kwemagetsi uye kudzivirira kutsemuka panguva inotevera yekupisa-yepamusoro kurapwa.
- ,Process: Kukandwa kunodziiswa zvishoma nezvishoma muchoto chinodzorwa kusvika kune tembiricha yemhando300–400°C (572–752°F).
- ,Key Parameters: Mwero wekupisa unochengetwa pa50–100°C/awa (90–180°F/awa)kuve nechokwadi chekugovera tembiricha yakafanana.
,2. Austenitizing (Normalizing),
- ,Chinangwa: Kuita homogenize iyo microstructure, kunatsa saizi yezviyo, uye kunyungudutsa carbides.
- ,Process:
- Castings inopisa kusvika kune austenitizing tembiricha ye890–940°C (1634–1724°F).
- Yakabatwa pane tembiricha iyiMaawa 1–2 pa25 mm (1 inch) yechikamu chakakorakuve nechokwadi chekushandura chikamu chakazara.
- Yakatonhodzwa mumhepo yakanyarara (normalizing) kusvika kukamuri yekushisa.
,3. Kupisa,
- ,Chinangwa: Kubvisa kushushikana kwasara, kuvandudza kuomarara, uye kudzikamisa iyo microstructure.
- ,Process:
- Mushure me normalizing, ma castings anodzoserwa kune inodziya tembiricha ye590–720°C (1094–1328°F).
- Yakanyikwa patembiricha iyiMaawa 1–2 pa25 mm (1 inch) yekukora.
- Yakatonhodzwa mumhepo kana muchoto-yakatonhodzwa pachiyero chinodzorwa kudzivirira kutsva kwekushushikana kutsva.
,4. Kuongorora Kwepashure-Kurapwa,
- ,Chinangwa: Kuona kutevedzera ASTM A216 zviyero.
- ,Process:
- Mechanical kuyedzwa (semuenzaniso, kusimba kwesimba, goho simba, kuoma).
- Microstructural analysis kuti ive nechokwadi chekufanana uye kusavapo kwekuremara.
- Dimensional cheki yekusimbisa kugadzikana mushure mekupisa kurapwa.
,Sarudzo Matanho (Nyaya-Yakananga),
- ,Kuderedza Stress: Kune ma geometries akaoma, imwe yekuwedzera-yekuzorodza kutenderera inogona kuitwa pa600–650°C (1112–1202°F)Kubvisa kushushikana kwasara kubva kumachining kana welding.
- ,Controlled Cooling: Pakukandwa kwechikamu chakakora, mitengo inononoka kutonhora (semuenzaniso, kutonhora kwechoto) inogona kuiswa panguva yekudziya kuwedzera kusimba.
,Pfungwa Huru,
- ,Furnace Atmosphere: Kwakarerekera kana zvishoma oxidizing mamiriro ekunze kudzivirira decarburization.
- ,Tembiricha Uniformity: ± 10°C kushivirira kuti uve nechokwadi chekuenderana.
- ,Zvinyorwa: Kutevedzwa kwakazara kwematanho ekurapa kupisa (nguva, tembiricha, mitengo yekutonhodza) yekusimbisa mhando.
Iyi nzira inovimbisaTWS concentric butterfly valvemuviriD341B1X-16muWCB castings inosangana neASTM A216 zvinodiwa zvekusimba simba (≥485 MPa), goho simba (≥250 MPa), uye elongation (≥22%), zvichiita kuti zvive zvakakodzera kune yakakwirira-tembiricha uye kumanikidza kushandiswa mumavharuvhu, pombi, uye pombi masisitimu.
