WCB, i-carbon steel casting material lehambisana ne-ASTM A216 Grade WCB, ihamba ngendlela lejwayelekile yekuphatfwa ngekushisa kute kuzuzwe timphahla letidzingekako temshini, kusimamisa kwebukhulu, kanye nekumelana nekucindzeteleka lokushisako. Ngezansi kunencazelo lephelele yekusebenta lokujwayelekile kwekwelapha kushisa kwe-WCB .YD7A1X-16 Ivalvu yeluvivanelokulahliwe:
.1. Kushisa.
- .Injongo: Kunciphisa ema gradients lashisako kanye nekuvikela kudzabuka ngesikhatsi sekwelashwa lokulandzelako lokushisa kakhulu.
- .Inchubo: Tintfo letilahliwe tishiswa kancane kancane esitofini lesilawulwako kuya esigabeni sekushisa se .300-400°C (572-752°F).
- .Emapharamitha Labalulekile: Lizinga lekushisa ligcinwa ku .50-100 ° C / lihora (90-180 ° F / lihora)kucinisekisa kusabalalisa lokufanako kwekushisa.
.2. Kufaka ekhatsi (Kujwayeleka).
- .Injongo: Kute kwentiwe lokufanako kwesakhiwo lesincane, kucwengisisa bukhulu betinhlavu, bese kuncibilikisa ema carbides.
- .Inchubo:
- Tintfo letilahliwe tishiswa tibe sezingeni lelishisako le-austenitizing le-890-940°C (1634-1724°F).
- Kugcinwe kulelizinga lekushisaEmahora langu-1-2 nga-25 mm (1 intshi) yesigaba sebukhulukucinisekisa kuguculwa kwesigaba ngalokuphelele.
- Kupholiswe emoyeni lomile (kujwayelekile) kuya ekushiselweni kweligumbi.
.3. Kufutfumala.
- .Injongo: Kucedza kucindzeteleka lokusele, kwenta ncono kucina, kanye nekusimamisa i-microstructure.
- .Inchubo:
- Ngemuva kwekujwayeleka, ema-castings aphindze ashiswe abe sezingeni lelishisako le-100.590-720°C (1094-1328°F).
- Icwiliswe kulelizinga lekushisaEmahora langu-1-2 nga-25 mm (1 intshi) yebukhulu.
- Ipholiswe emoyeni noma ipholiswe ngesithando ngesilinganiso lesilawulwako kwentela kuvikela kwakheka kwekucindzeteleka lokusha.
.4. Kuhlolwa Ngemuva Kwekwelashwa.
- .Injongo: Kucinisekisa kuhambisana nemazinga e-ASTM A216.
- .Inchubo:
- Kuhlolwa kwemishini (sib., emandla ekucindzeteleka, emandla ekukhicita, kucina).
- Kuhlatiya kwesakhiwo lesincane kucinisekisa kufana kanye nekungabi khona kwetici.
- Kuhlolwa kwetilinganiso kucinisekisa kusimamisa ngemuva kwekwelashwa ngekushisa.
.Tinyatselo Letingakhetfwa (Letikhetsekile Ecaleni).
- .Kucedza kucindzeteleka: Kuma geometries layinkimbinkimbi, umjikeleto lowengetiwe wekucedza kucindzeteleka ungentiwa ku .600-650°C (1112-1202°F)kucedza kucindzeteleka lokusele kusuka ekusebentiseni ngemishini noma ngekushisela.
- .Kupholisa Lokulawulwako: Ku castings yesigaba lesikhulu, emazinga ekupholisa kancane (sib., kupholisa kwesithando) kungasetjentiswa ngesikhatsi sekushisa kwentela kukhulisa ductility.
.Tintfo Letimcoka Lekucatshangelwako.
- .Umkhatsi Wesithando: Umoya longatsatsi luhlangotsi noma lone oxidizing kancane kwentela kuvikela kukhishwa kwe carbon.
- .Kufana kwekushisa: ±10°C kubeketela kwentela kucinisekisa imiphumela lehambisanako.
- .Imibhalo: Kulandzelela lokugcwele kwemapharamitha ekwelashwa kwekushisa (sikhatsi, lizinga lekushisa, emazinga ekupholisa) kwentela kucinisekisa lizinga.
Lenchubo icinisekisa kutsiTWS Ivalvu levivane lesemkhatsiniumtimbaD341B1X-16ku WCB castings kuhlangabetana netidzingo te ASTM A216 temandla ekucindzeteleka (≥485 MPa), emandla ekukhicita (≥250 MPa), kanye nekukhula (≥22%), kwenta kutsi tilungele kusetjentiswa lokusetulu kwekushisa kanye nekucindzeteleka kumavalvu, emaphampu, kanye netinhlelo temapayipi.
KusukelaIVALUVU ye-TWS, lonelwati ekukhiciteni .irabha lehleti ivalvu levivane YD37A1X, ivalve yesango, kukhicita kwe-Y-strainer.
