Ka tlase ke tlhaloso e qaqileng ea mokhoa o tloaelehileng oa kalafo ea mocheso bakeng sa WCB.YD7A1X-16 Valve ea Serurubeleho lahla:
1. Ho futhumatsa
- Morero: Ho fokotsa maemo a mocheso le ho thibela ho petsoha nakong ea kalafo e latelang ea mocheso o phahameng.
- TshebetsoLi-castings li futhumatsoa butle-butle ka ontong e laoloang ho fihlela mochesong o phahameng oa300–400°C (572–752°F).
- Liparamente tsa BohlokoaSekhahla sa ho futhumatsa se bolokoa ho50–100°C/hora (90–180°F/hora)ho netefatsa kabo e ts'oanang ea mocheso.
2. Ho matlafatsa (Ho etsa hore lintho li be boemong bo tloaelehileng)
- Morero: Ho kopanya sebopeho sa micro, ho ntlafatsa boholo ba lijo-thollo, le ho qhala lik'habohaedreite.
- Tshebetso:
- Li-castings li futhumatsoa ho fihlela mochesong o matlafatsang oa890–940°C (1634–1724°F).
- E bolokiloe mochesong ona bakeng saLihora tse 1-2 ka 25 mm (inch e le 'ngoe) ea botenya ba karoloho netefatsa phetoho e felletseng ea mohato.
- E phodisitsoe moeeng o sa sisinyeheng (o etsang hore e be boemong bo tloaelehileng) ho fihlela mochesong oa kamore.
3. Ho leka-lekanya
- Morero: Ho imolla likhatello tse setseng, ho ntlafatsa ho tiea, le ho tsitsisa sebopeho sa microstructure.
- Tshebetso:
- Kamora ho normalize, di-castings di futhumatswa hape ho fihlela mochesong o batang wa590–720°C (1094–1328°F).
- E kolobisitsoe mochesong ona bakeng saLihora tse 1-2 ka botenya ba 25 mm (inch e le 'ngoe).
- E phodiswa moeeng kapa ka ontong ka lebelo le laolwang ho thibela ho thehwa ha kgatello e ntjha.
4. Tlhahlobo ea Kamora Kalafo
- Morero: Ho netefatsa ho latela maemo a ASTM A216.
- Tshebetso:
- Teko ea mechine (mohlala, matla a ho thapolla, matla a ho ikatisa, ho thatafala).
- Tlhahlobo ea sebopeho sa microstructure ho netefatsa hore ho na le ho tšoana le ho se be le likoli.
- Liteko tsa litekanyo ho netefatsa botsitso ba kalafo ea kamora mocheso.
Mehato ea Boikhethelo (E Ikhethang ka Nyeoe)
- Ho Imolla Khatello ea KelelloBakeng sa li-geometri tse rarahaneng, potoloho e eketsehileng ea ho imolla khatello ea maikutlo e ka etsoa ho600–650°C (1112–1202°F)ho felisa likhatello tse setseng tse bakoang ke ho sebetsa ka machining kapa ho tjheseletsa.
- Pholiso e Laoloang: Bakeng sa ho lahla likarolo tse teteaneng, sekgahla sa ho phodisa se liehang (mohlala, ho phodisa ka ontong) se ka sebediswa nakong ya ho futhumatsa ho ntlafatsa ho ductility.
Lintlha tsa Bohlokoa
- Sepakapaka sa Sebōpi: Sepakapaka se sa nke lehlakore kapa se oksidang hanyane ho thibela ho tlosoa ha khase.
- Ho Tšoana ha Thempereichara: Mamello ea ±10°C ho netefatsa liphetho tse tsitsitseng.
- Litokomane: Ho latela ka botlalo diparamente tsa kalafo ya mocheso (nako, mocheso, sekgahla sa ho phodisa) bakeng sa netefatso ya boleng.
