I-WCB, i-carbon steel casting material ehambelana ne-ASTM A216 yeBanga le-WCB, iqhuba inkqubo yonyango yokushisa esemgangathweni ukufezekisa iipropati ezifunekayo zomatshini, ukuzinza kwe-dimensional, kunye nokuchasana noxinzelelo lwe-thermal. Apha ngezantsi kukho inkcazo eneenkcukacha zomqukuqelo oqhelekileyo wonyango lwe-WCBYD7A1X-16 Ivalve yebhabhathaneiicastings:
...1. Ukufudumala...
- ...Injongo: Ukunciphisa i-gradients ezishushu kunye nokuthintela ukuqhekeka ngexesha lonyango olulandelayo lobushushu obuphezulu.
- ...Inkqubo: Iicastings zifudunyezwa kancinane kwiziko elilawulwayo ukuya kuluhlu lweqondo lobushushu300–400°C (572–752°F).
- ...Iiparamitha eziphambili: Izinga lokufudumeza ligcinwa50–100°C/yure (90–180°F/yure)ukuqinisekisa ukuhanjiswa kobushushu obufanayo.
...2. Ukuqinisa (UkuQinisa)...
- ...Injongo: Ukwenza i-homogenize i-microstructure, ukucokisa ubungakanani beenkozo, kunye nokunyibilikisa i-carbides.
- ...Inkqubo:
- Iicastings zifudunyezwa kwiqondo lobushushu obuyi-austenitizing890–940°C (1634–1724°F).
- Ibanjelwe kobu bushushu ukwenzelaIiyure ezi-1-2 nge-25 mm (i-intshi eyi-1) yobukhulu becandeloukuqinisekisa inguqu epheleleyo yesigaba.
- Ipholiswe kumoya ongashukumiyo (i-normalizing) kwiqondo lobushushu begumbi.
...3. Ukufudumeza...
- ...Injongo: Ukuthomalalisa uxinzelelo olushiyekileyo, ukuphucula ukomelela, kunye nokuzinzisa i-microstructure.
- ...Inkqubo:
- Emva kokwenziwa kwesiqhelo, iicastings ziphinda zifudunyezwe kwiqondo lobushushu elipholileyo590–720°C (1094–1328°F).
- Ifakwe kobu bushushu ukwenzelaIiyure ezi-1 ukuya kwezi-2 kwi-25 mm (i-intshi enye) yobunzima.
- Ipholile emoyeni okanye kwisithando somlilo-ipholile ngesantya esilawulwayo ukuthintela ukubunjwa koxinzelelo olutsha.
...4. Ukuhlolwa kwasemva koNyango...
- ...Injongo: Ukuqinisekisa ukuthotyelwa kwemigangatho ye-ASTM A216.
- ...Inkqubo:
- Uvavanyo lomatshini (umzekelo, ukomelela, ukomelela kwemveliso, ubulukhuni).
- Uhlalutyo lweMicrostructural ukuqinisekisa ukufana kunye nokungabikho kweziphene.
- Iitshekhi zeDimensional zokuqinisekisa uzinzo emva kobushushu bonyango.
...Amanyathelo Angakhethwa (Ngokwemeko-Angqale)...
- ...Ukunciphisa Uxinzelelo: Kwiijometri ezintsonkothileyo, umjikelo owongezelelweyo wokuphelisa uxinzelelo unokwenziwa600–650°C (1112–1202°F)Ukuphelisa uxinzelelo olushiyekileyo kumatshini okanye kwi-welding.
- ...Ukupholisa okuLawulweyo: Kusakhelo secandelo elishinyeneyo, ukupholisa okucothayo (umzekelo, ukupholisa eziko) kunokusetyenziswa ngexesha lobushushu ukuqinisa ukudumba.
...Iingqwalasela ezingundoqo...
- ...Umoya weSithando somlilo: Indawo engathathi hlangothi okanye ene-oxidizing kancinci ukunqanda i-decarburization.
- ...Ubushushu obufanayo: ± 10°C ukunyamezela ukuqinisekisa iziphumo ezingaguqukiyo.
- ...Amaxwebhu: Ukulandelelwa ngokupheleleyo kweeparamitha zonyango lobushushu (ixesha, ubushushu, amazinga okupholisa) ukuqinisekisa umgangatho.
Le nkqubo iqinisekisaTWS ivalve yebhabhathane egxileumzimbaD341B1X-16kwi-WCB castings ihlangabezana neemfuno ze-ASTM A216 zamandla e-tensile (≥485 MPa), amandla esivuno (≥250 MPa), kunye nobude (≥22%), okwenza ukuba bafanelekele ubushushu obuphezulu kunye noxinzelelo lwezicelo kwiivalvu, iimpompo, kunye neenkqubo zombhobho.
UkusukaIvalve yeTWS, onamava ekuveliseniirabha ehleli ivelufa yebhabhathane YD37A1X, ivalve yesango, i-Y-strainer yokwenziwa.
