Ngokubanzi, uyilo lweenkqubo zokungena lulandela imigaqo emithathu:
1. Ukugalela ngokukhawuleza: ukunciphisa ukuhla kweqondo lokushisa, ukuhla kunye ne-oxidation;
2. Ukugalela okucocekileyo: gwema isizukulwana se-slag kunye nokungcola, kwaye ukhusele i-slag kwintsimbi etyhidiweyo emngxunyeni;
3. Ukuthululwa kwezoqoqosho: ukwandisa isivuno senkqubo.
1.Indawo yecandelo lokuminxa
1. Xa uqulunqa inkqubo yokuthululela, into yokuqala yokuqwalasela indawo yecandelo lokuthintela ukuhamba, kuba imisela isantya sokuzalisa. Ngokubanzi, kukho iindawo ezimbini zemveli zokulungiselela amacandelo okuminxa.
2.Enye kukuyicwangcisa phakathi kwembaleki esecaleni kunye nembaleki yangaphakathi. Inani lisenokungqinelana nenani lembaleki yangaphakathi. Kukwabizwa ngokuba kukugalela uxinzelelo. Ekubeni ubuncinci be-cross-section isondele kwi-casting, isantya somgca wentsimbi etyhidiweyo siphezulu kakhulu xa singena emgodini.
3.Enye ibekwe phakathi kwe-sprue kunye nembaleki esecaleni, kunye necandelo elinye lokuthintela ukuhamba, elikwabizwa ngokuba yi-pressureless pouring.
I-4.Imveliso yentsimbi yanamhlanje ayinakuhlukaniswa kwi-teknoloji yokucoca. Ukuze kusetyenziswe ngcono izihluzi ze-ceramic ze-foam, i-sprue kufuneka isetyenziswe njengecandelo lokuthintela ukuhamba kwindlela yoyilo lwenkqubo.
Izinto ekufuneka ziqwalaselwe
I-1.Ixesha lokugalela, lo ngomnye wemisebenzi yenkqubo yokugalela, kwaye kukho i-algorithms eyahlukeneyo. Kule mihla, isoftware yokulinganisa isetyenziswa kakhulu ukubala. Ngaba ikho indlela ekhawulezayo yokubala ngesandla? Impendulo: Ewe, kwaye ilula.
T sek =√(W.lb)
Phakathi kwazo: t lixesha lokuthulula, iyunithi imizuzwana, i-W ubunzima bokuthulula, iyunithi iipounds. Yigcine ilula.
2. I-friction coefficient. Intsimbi etyhidiweyo iya kugudla udonga lokungunda ngexesha lokugalelwa. Ukungqubana kuya kwenzeka phakathi kwentsimbi etyhidiweyo kwaye kuya kubakho ukulahleka kwamandla, ngoko kufuneka kuthathelwe ingqalelo.
Ngokuqhelekileyo, kwiiplati ezinodonga oluncinci, i-coefficient ye-friction § kufuneka ibe yincinci njenge-0.2; kwiindawo ezishinyeneyo nezisikwere, i-friction coefficient§ifanele ibe yi-0.8.
3.Ngokuqinisekileyo, unokuchaneka ngakumbi. Itshathi engezantsi ingasetyenziselwa ukuyifumana.
