Izingxenye Zephampu Yokusakaza Ngokwezifiso / Ukunemba Kokusakaza

I-castin yokutshala imaliinqubo ye-g isho ukwenza imodeli ngengcina, ukugoqa ungqimba lwento ephikisayo njengobumba ngaphandle, ukushisa ingcina ukuze incibilike futhi iphume, ukuze uthole igobolondo elingenalutho elakhiwe ngezinto eziphikisayo, bese uthela insimbi.egobolondweni elingenalutho ngemva kokuncibilika.Ngemva kokuba insimbi ipholile, i-refractory material iyachotshozwa ukuze kutholakale isikhunta sensimbi.Le nqubo yokucubungula insimbi ibizwa ngokuthi i-investment casting, eyaziwa nangokuthi i-investment casting noma ukulahlekelwa kwe-wax cast.

Imininingwane Yomkhiqizo

Omaka bomkhiqizo

inqubo yezobuchwepheshe

Inqubo yezobuchwepheshe yomzimba wephampu yensimbi engagqwali ukunemba imi kanje:

1. Ngenxa yokungamanzi kahle kwensimbi encibilikisiwe, ukuze kuvinjwe ukuvala okubandayo kanye nokuthululwa okwanele kwezinsimbi zensimbi engagqwali, ubukhulu bodonga lwensimbi engagqwali akufanele bube ngaphansi kuka-8mm;ukwakheka kwesistimu yokuthulula kufanele kube lula, futhi ubukhulu be-cross-sectional kufanele bube bukhulu kunokwensimbi;ukusakaza okomile noma ukuphonsa okushisayo kufanele kusetshenziswe.Isikhunta sokuphonsa: Khulisa kahle izinga lokushisa elithululwayo, ngokuvamile elingu-1520°~1600°C, ngoba izinga lokushisa elithelayo liphezulu, ukushisa okuphezulu kwensimbi encibilikisiwe kukhulu, futhi isikhathi sokugcina isimo soketshezi side.Kodwa-ke, uma izinga lokushisa liphezulu kakhulu, lizodala izinhlamvu ezimahhadla, imifantu eshisayo, izimbotshana nezimbotshana ezinamathelayo.Ngakho-ke ekubunjweni okuncane okujwayelekile, okunodonga oluncane futhi okunokwakheka okuyinkimbinkimbi, izinga lokushisa layo lokuthulula lilingana nephoyinti lokuncibilika lensimbi + 150 ℃;ekubunjweni okukhulu, okunodonga oluqinile, izinga lokushisa layo lokuthulula kufanele libe ngaphezulu kuka-100 ℃ ngaphezu kwendawo yalo yokuncibilika.

2. Njengoba ukuncipha kwensimbi engagqwali kuphakeme kakhulu kunaleyo yensimbi ekhonjiwe, ukuze kuvinjwe imigodi enciphayo ekubunjweni, izinyathelo ezinjengama- risers, insimbi ebandayo kanye nezibonelelo zisetshenziswa kakhulu enqubweni yokuphonsa ukuze kuzuzwe ukuqina okulandelanayo.

Izinzuzo Zomkhiqizo

Ukukhishwa kwe-investimenti kubuye kubizwe ngokunemba kokusakaza/ukukhipha iwaxing.Uma kuqhathaniswa nezinye izindlela zokulingisa kanye nezindlela zokwakha izingxenye, ukutshala imali kunezinzuzo ezilandelayo:

1. Ukunemba kwe-dimensional kokusakazwa kuphezulu, inani lokuma okungaphezulu lilungile, ukunemba kobukhulu bokulingisa kungafinyelela amamaki angu-4-6, futhi ukugoqa okuphezulu kungafinyelela ku-0.4-3.2μm, okunganciphisa kakhulu imvume yokucubungula ukukhiqiza futhi angakwazi ukubona ukukhiqizwa okungasala.ukunciphisa izindleko zokukhiqiza.

2. Ingakwazi ukulingisa ngezimo eziyinkimbinkimbi futhi okunzima ukuyicubungula ngezinye izindlela.Usayizi wohlaka wokulingisa unobubanzi obusuka kumamilimitha ambalwa ukuya ezinkulungwaneni zamamilimitha, ubuncane bokujiya bodonga bungu-0.5mm, kanti ubukhulu bembobo obuncane bungaphansi kuka-1.0mm.

3. Izinto ze-alloy azikhawulelwe: izinto ezifana ne-carbon steel, insimbi engagqwali, insimbi ye-alloy, i-alloy yethusi, i-aluminium alloy, i-high-temperature alloy, i-titanium alloy kanye nensimbi eyigugu ingakhiqizwa ngokunemba kokusakazwa.Okwezinto ze-alloy okunzima ukuzibumba, ukushisela nokusika, ngaphezulu Ifaneleka ngokukhethekile ukukhiqizwa kokusakazwa okunembayo.

4. Ukuguquguquka okuphezulu kokukhiqiza nokuvumelana nezimo okuqinile.Ingasetshenziselwa ukukhiqiza ngobuningi kanye neqoqo elincane noma ngisho nokukhiqizwa kwesiqephu esisodwa.

Ukufingqa, ukusakaza okunembayo kunezinzuzo zesikali esincane sokutshala imali, umthamo omkhulu wokukhiqiza, izindleko eziphansi zokukhiqiza, ukwenziwa lula kwenqubo yomkhiqizo eyinkimbinkimbi, kanye nembuyiselo esheshayo ekutshalweni kwezimali.Ngakho-ke, isesimweni esihle emqhudelwaneni nezinye izinqubo nezindlela zokukhiqiza.
