Ukusakaza Ukukhubazeka Okujwayelekile - Ingxenye II

Izimbangela eziyisithupha zokukhubazeka okujwayelekile nezindlela zokuvimbela, ukungaqoqi kuzoba ukulahlekelwa kwakho! ((Ingxenye 2)

Sizoqhubeka nokukwethula kwezinye izinhlobo ezintathu zokusakaza amaphutha nezisombululo ezivamile.

4 Ukuqhekeka (ukuqhekeka okushisayo, ukuqhekeka okubandayo)

1)Izici:Ukubonakala komfantu kuyijika eliqondile noma elingajwayelekile, indawo eshisayo eshisayo ifakwe oxidized ngokumpunga okumnyama noma okumnyama futhi akukho cwebezelayo yensimbi, indawo ebandayo yokuqhekeka ihlanzekile futhi icwebezela okwensimbi. Imifantu yangaphandle ye-casting evamile ingabonakala ngokuqondile kodwa imifantu yangaphakathi idinga ukusebenzisa ezinye izindlela. Imifantu ivame ukuhlotshaniswa nokukhubazeka okufana ne-porosity kanye ne-slag, yenzeke ekujikeni ngaphakathi ekhoneni, ingxenye yogqinsi lwe-junction, isikhuphukeli esithelayo esixhunywe nesigaba esishisayo.

I-2) Izimbangela: Ukubunjwa kwensimbi yensimbi kuthambekele ekuqhekekeni, ngoba isikhunta sensimbi ngokwaso asiyona imvume, ukupholisa ngokushesha kuphumela kalula ekucindezelekeni okwandayo ekubunjweni. Ukuvula ngaphambi kwesikhathi kakhulu noma sekwephuze kakhulu, i-engeli yokuthela incane kakhulu noma inkulu kakhulu, ungqimba lukapende luncane kakhulu ect konke kuzodala ukuqhekeka kokulingwa. Ukuqhekeka kwesikhunta ngokwaso kungaholela kalula ekuqhekekeni.

3)Ungakuvimbela kanjani:
I Ukunaka ubuchwepheshe besakhiwo ukuze izingxenye ezingalingani zodonga zingashintsha ngokulinganayo ngokusebenzisa usayizi ofanele oyindilinga.
I Ukuze ulungise ukujiya kwe-coating ukuze zonke izingxenye zokusakaza zifinyelele izinga lokupholisa elidingekayo ngangokunokwenzeka ukuze ugweme ingcindezi enkulu ekubumbeni.
I Ukuze ulawule izinga lokushisa kwesikhunta sensimbi, lungisa ihhala lesikhunta kanye nokuqhekeka okufika ngesikhathi, ukhiphe ukubunjwa okubandayo kancane.

5 Ukuvala okubandayo (i-fusion embi)

1) Izici: Ukuvala okubandayo kuwumthungo noma imifantu engaphezulu enezinhlangothi eziyindilinga, yahlukaniswa i-oxide nokuhlanganisa okungaphelele, izivalo ezibandayo eziyingozi eziba “ukusakaza okuncane” . Izivalo ezibandayo zivame ukuvela odongeni olungaphezulu lokubunjwa, indawo encane evundlile noma eqondile, ukuxhuma kwezindonga eziwugqinsi nezincane, noma kumaphaneli amancane.

2) Izimbangela:
I Idizayini ye-Exhaust yesikhunta sensimbi ayinangqondo
I Izinga lokushisa lokusebenza liphansi kakhulu.
I Ikhwalithi yokupenda yokupenda yimbi (eyenziwe umuntu noma izinto zokwakha).
I Indawo yomgijimi eklanyelwe ayifanele.
I Ijubane lokuthela lihamba kancane nokunye.

3) Indlela yokuvimbela
I Idizayini efanele yomgijimi kanye nesistimu yokukhipha umoya.
I Enkulu-indawo mncane-odongeni Castings, ezinengilazi akufanele mncane kakhulu futhi ezifanele ukuqina ezinengilazi ukubumba kalula.
I Ukwenyusa izinga lokushisa lokusebenza kwesikhunta ngendlela efanele.
I Ukusebenzisa indlela yokuthela ethambekele.
I Ukusebenzisa ukubunjwa kwensimbi kokudlidliza kokuthulula.

6 amabhamuza (umgodi wesihlabathi)

1) Izici: Imigodi evamile ngokuqhathaniswa isendaweni yokuphonsa noma ngaphakathi, imise okufanayo nesihlabathi, ibonakala phezulu lapho ungathatha khona izinhlamvu zesihlabathi. Kukhona izimbobo zesihlabathi eziningi ngesikhathi esisodwa futhi indawo yokuphonsa i-orange peel shape.

2) Izimbangela:
I Sand core surface falling Isihlabathi esiwayo sasigoqwe ngensimbi kanye nendawo yokuphonsa ukuze sakhe imbobo.
Amandla e-Sand core surface awekho mahle, ayashiswa noma awalapheki ngokuphelele.
I Ubukhulu isihlabathi core kanye isikhunta yangaphandle ayihambisani, lapho isikhunta clamping ochotshoziwe isihlabathi core.
I Mold icwiliswe emanzini e-sand graphite.
Izihlabathi ezivela ku-sand core friction ku-ladle& umgijimi ziwela emgodini ngoketshezi lwensimbi.

3) Indlela yokuvimbela:
I Ukwenza umgogodla wesihlabathi ngokuqinile ngokuhambisana nenqubo futhi uhlole ikhwalithi.
I Ukufanisa umgogodla wesihlabathi nosayizi besikhunta sangaphandle.
I Ukuhlanza amanzi e-graphite ngesikhathi.
I Ukuze ugweme ladle kanye sand core friction.
I Ukuhlanza isihlabathi endaweni yesikhunta lapho ubeka umongo wesihlabathi.
