Endlelo ro Hlawula hi ku Hisisa ra WCB Castings

WCB, xitirhisiwa xo hoxa nsimbi ya khaboni lexi fambelanaka na ASTM A216 Grade WCB, xi hundza eka endlelo ro basisa hi ku hisa leri ringaniseriweke ku fikelela swivumbeko swa michini leswi lavekaka, ku tshamiseka ka dimensional, na ku lwisana na ntshikelelo wa mahiselo. Laha hansi ku na nhlamuselo ya vuxokoxoko bya maendlelo ya ntirho ya ntolovelo ya vutshunguri bya ku hisa ya WCBYD7A1X-16 Valve ya Phaphataniswilo leswi hoxiweke: .

Ku1. Ku hisa ka ha ri emahlweniKu

• KuXikongomelo: Ku hunguta ti thermal gradients naku sivela ku pandzeka hinkarhi wa vutshunguri bya mahiselo yale henhla lebyi landzelaka.
• KuEndlelo: Ti castings ti hisiwa hakatsongotsongo eka furniture leyi lawuriwaka kuya eka mahiselo ya300–400°C (572–752°F) ..
• KuTipharamitha ta Nkoka: Mpimo wa ku hisa wu hlayisiwa eka50–100°C/wara (90–180°F/wara) .ku tiyisisa ku hangalasiwa ka mahiselo loku fanaka.

Ku2. Ku titimela (Ku tolovela) .Ku

• KuXikongomelo: Ku endla leswaku microstructure yi va homogenize, ku antswisiwa vukulu bya mavele, na ku n’okisa ti carbides.
• KuEndlelo: 1 .
• Ti castings ti hisiwa kuya eka mahiselo ya austenitizing ya890–940°C (1634–1724°F) hi xitalo..
• Yi khomiwile eka mahiselo lawa ku ringana1–2 wa tiawara hi 25 mm (1 inch) ya ku enta ka xiphemuku tiyisisa ku cinca ka xiyenge loku heleleke.
• Yi kufumetiwa eka moya wo rhula (normalizing) kuya eka mahiselo ya kamara.

Ku3. Ku hlundzukaKu

• KuXikongomelo: Ku hunguta ntshikelelo lowu saleke, ku antswisa ku tiya, na ku tiyisisa microstructure.
• KuEndlelo: 1 .
• Endzhaku ko normalise, ti castings titlhela ti hisiwa kuya eka tempering temperature ya590–720°C (1094–1328°F) ..
• Yi tsakamile eka mahiselo lawa ku ringana1–2 wa tiawara hi 25 mm (1 inch) ya vukulu.
• Yi kufumetiwa emoyeni kumbe yi kufumetiwa hi furnace hi mpimo lowu lawuriwaka ku sivela ku tumbuluxiwa ka ntshikelelo wuntshwa.

Ku4. Ku Kamberiwa ka le Ndzhaku ka VutshunguriKu

• KuXikongomelo: Ku tiyisisa ku landzeleriwa ka swipimelo swa ASTM A216.
• KuEndlelo: 1 .
• Ku kamberiwa hi michini (xikombiso, matimba ya tensile, matimba ya mbuyelo, ku tiya).
• Nxopaxopo wa microstructural ku tiyisisa ku fana na ku pfumaleka ka swihoxo.
• Ku kamberiwa ka ti dimensions ku tiyisisa ku tshamiseka endzhaku ka vutshunguri bya ku hisa.

KuMagoza yo Hlawuleka (Yi kongomisiweke eka Mhaka) .Ku

• KuKu Pfuxeta Ntshikelelo: Eka tijiometri leti rharhanganeke, xirhendzevutani xo engetela xo hunguta ntshikilelo xi nga endliwa eka600–650°C (1112–1202°F) .ku herisa ntshikelelo lowu saleke kusuka eka machining kumbe welding.
• KuKu Pfuxeta loku Lawulaka: Eka ti thick-section castings, ti rates to kufumela letinga nonoka (xikombiso, furnace cooling) tinga tirhisiwa hinkarhi wa tempering kuva ku engetelela ductility.

KuSwilo swa nkoka leswi faneleke ku tekeriwa enhlokweniKu

• KuXibakabaka xa Furnace: Neutral kumbe oxidizing nyana atmosphere ku sivela decarburization.
• KuKu Fana ka Mahiselo: ±10°C ku tiyisela ku tiyisisa mbuyelo lowu nga cincekiki.
• KuMatsalwa ya matsalwa: Ku landzelerisiwa loku heleleke ka ti parameters ta vutshunguri bya kuhisa (nkarhi, mahiselo, tihakelo ta ku kufumela) kuva ku tiyisisiwa khwalithi.

Endlelo leri ri tiyisisaTWS valve ya phaphatani leyi nga exikarhimiriD341B1X-16eka ti castings ta WCB ti fikelela swilaveko swa ASTM A216 swa matimba ya tensile (≥485 MPa), matimba ya mbuyelo (≥250 MPa), na elongation (≥22%), leswi endlaka leswaku ti lulamela eka switirhisiwa swa mahiselo yale henhla na ntshikelelo eka ti valve, tipompo, na tisisiteme ta tiphayiphi.

Ku sukaVALVE YA TWS, loyi a nga ni ntokoto eku humesenirhaba leyi tshameke concentric phaphatani valve YD37A1X, valve ya gede, ku endliwa ka Y-strainer.
