Ukuphosa Iziphene Eziqhelekileyo

Ii-castings ezintandathu eziqhelekileyo iziphene'indlela yokuthintela kunye nezizathu, hayi ukuqokelelaing iya kubailahleko yakho! ((Inxalenye 1)

Inkqubo yokuvelisa i-cast, izinto ezinefuthe kunye neziphene okanye ukungaphumeleli kwe-cast akunakuphepheka, ezibangela ilahleko enkulu kwishishini. Namhlanje, ndiza kwazisa i-cast iintlobo ezintandathu zeziphene eziqhelekileyo kunye nesisombululo, ndinethemba lokuba iluncedo kwishishini le-foundry.

1Iimbobo (amaqamza, umngxuma wokutshixa, iPokotho)

1)Iimbonakalo:Kukho imingxunya ngaphakathi komphezulu okanye kwimingxunya, ingqukuva, i-oval okanye imilo engacwangciswanga, ngamanye amaxesha imingxunya emininzi yenza umoya ophantsi kwesikhumba ngokuqhelekileyo imile okwepere. Umngxuma wokuminxana unemilo engacwangciswanga kwaye umphezulu orhabaxa. Ipokotho ngumphezulu ogobileyo kumphezulu othambileyo. Imingxunya ekhanyayo ibonakala ngokujonga, umngxuma wepin ungafunyanwa emva kokulungiswa ngoomatshini.
2)Izizathu:
l Ubushushu bokufudumeza kwangaphambili kwesikhunta buphantsi kakhulu, isinyithi esilulwelo sidlula kwinkqubo yokugalela siphola ngokukhawuleza kakhulu.
l Uyilo olubi lokukhupha umoya kwisikhunta, iigesi azinakukhutshwa ngaphandle kokuphazanyiswa.
Ipeyinti ayilunganga, i-exhaust ngokwayo ayisebenzi kakuhle, kuquka ne-volatilization okanye iigesi zokubola kwayo.
l Imingxuma kunye nemingxunya yomphezulu wemingxunya yesikhunta, emva kokuba isinyithi esilulwelo sigalelwe kwimingxuma, ukwanda ngokukhawuleza kwesinyithi esilulwelo esicinezelweyo segesi yomngxuma ukuze senze umngxuma wokutshixa.
Umphezulu womngxuma ubolile kwaye awukacocwa.
l Izinto ezikrwada (ii-cores) zigcinwe ngendlela engafanelekanga, ngaphandle kokuzifudumeza ngaphambi kokuba zisetyenziswe.
l Isixhobo sokunciphisa esingasebenzi kakuhle, okanye idosi engafanelekanga okanye ukusebenza ngendlela engafanelekanga.
3) Indlela yokuthintela:
I-mold ukuze ifudumale ngokupheleleyo, ubukhulu be-grafayithi (i-grafayithi) akufuneki bube buncinci kakhulu kwaye bube nokuphefumla okungcono.
Sebenzisa indlela yokuphosa ethambekileyo.
l Izinto ezikrwada mazigcinwe kwindawo eyomileyo nengenisa umoya, xa zisetyenziselwa ukufudumeza.
l Khetha i-arhente yokunciphisa i-deoxidation effect elungileyo (i-magnesium).
l Ubushushu bokugalela akufuneki bube phezulu kakhulu.

2 Ukuncipha

1) Iimpawu:Ukuncitshiswa ngumngxuma ongaphezulu okhoyo phezu komphezulu okanye ngaphakathi kwe-casting. Ukuncitshiswa kancinci kukuncitshiswa okuncinci okusasazekileyo kweenkozo ezirhabaxa, okuhlala kwenzeka kwi-casting kufutshane nomphezulu, iingcambu eziphakamayo, iindawo ezityebileyo, ubukhulu bodluliselo lodonga kunye nomgca omkhulu.

2) Izizathu:
l Ubushushu bokusebenza kwe-mold abuzange buhlangabezane neemfuno zokuqina kwecala.
l Ukukhetha okungafanelekanga kwengubo, ubukhulu bengubo abulawulwa kwiindawo ezahlukeneyo.
l Indawo yokuphosa kuyilo lwesikhunta ayifanelekanga.
Uyilo lwe-riser yokuthulula aluphumelelanga ukufezekisa ngokupheleleyo indima.
l Ubushushu bokugalela buphantsi kakhulu okanye buphezulu kakhulu.

3) Indlela yokuthintela:
l Ukunyusa ubushushu beenkuni.
l Ukulungisa ubukhulu bepeyinti kunye nepeyinti efafazwa ngokulinganayo. Xa ipeyinti iwela kwaye kufuneka ilungiswe, akufuneki yenze ipeyinti eqokelelweyo yasekuhlaleni.
l Ukufudumeza isikhunta sendawo okanye ukugquma kwendawo kusetyenziswa izixhobo zokugquma ubushushu.
l Beka ibhloko yekopolo eshushu kwindawo eshushu uze upholise indawo yasekuhlaleni.
l Ukuyila iradiator kwisikhunta, okanye ngesantya sokupholisa esikhawulezileyo kwiindawo zasekuhlaleni ezinje ngamanzi, okanye ukutshiza amanzi ngaphandle kwesikhunta.
l Ngeqhekeza elibandayo lokukhupha impahla elisuswayo, elibekwe ngokudibeneyo ngaphakathi komngxuma, ukuze kuthintelwe ukuba imveliso eqhubekayo, ngokwayo ayipholi ngokwaneleyo.
l Ukuyila isixhobo soxinzelelo kwi-riser yesikhunta.
l Ukuyila inkqubo yokuvala iigeyithi ngokuchanekileyo, ukukhetha ubushushu obufanelekileyo bokugalela.

Imingxunya emi-3 yeSlag (i-flux slag kunye ne-metal oxide slag)

1) Iimpawu:Umngxuma we-slag unemingxuma ekhanyayo okanye emnyama kwindawo yokuphosa, yonke okanye inxalenye yomngxuma yayizaliswe yi-slag. Akukho lula ukuyifumana imo engaqhelekanga, indawo encinci ye-flux slag, emva koko ibonise umngxuma ogudileyo. Isasazwa ngokubanzi kwindawo esezantsi yendawo yokuphosa, kufutshane nekona ye-runner okanye ye-casting, i-oxide slag isasazwa kakhulu kwisango le-mesh kufutshane nomphezulu, ngamanye amaxesha ibe zii-flakes okanye ilifu elingacwangciswanga eline-wrinkled okanye i-sheet sandwich, okanye ii-flocculent castings, ihlala iqhekeka kwi-sandwich ene-oxide. Yenye yezona zinto ziphambili zokuphosa imifantu.

2)Isizathu:Umngxuma we-slag ubangelwa kakhulu kukunyibilikisa i-alloy kunye nenkqubo yokubumba (kubandakanya uyilo olungalunganga lwenkqubo yokugada), i-mold ngokwayo ayibangeli umngxuma we-slag, kwaye ukusebenzisa i-mold yesinyithi yenye yezona ndlela zisebenzayo zokuphepha i-slag.

3) Indlela yokuthintela:
l Ukuyila inkqubo yokugada ngokuchanekileyo, okanye sebenzisa isihluzi sefayibha ephosiweyo.
l Ukusebenzisa indlela yokugalela ethambekileyo.
Ukukhetha iarhente yokudibanisa nokulawula umgangatho ngokungqongqo.

Ezinye iziphene ezintathu zokufaka i-cast ziza kuqhubeka kwiveki ezayo. Enkosi.
