Wazi kangakanani ngokusetshenziswa kwemishini yokuphonsa eqhubekayo ekwakheni insimbi eyigugu?

Imishini yokuphonsa eqhubekayo yaziwa nangokuthi imishini yokukhipha insimbi, okuyindlela ethuthukisiwe yokudweba phansi. Umgomo wayo wokusebenza uwukuncibilikisa izinsimbi ezingezona ayoni ngaphansi kokushisisa kokungenisa okunyakazayo, ngokuqhubekayo uzithulule esikhunjeni sensimbi esikhethekile esibizwa ngokuthi i-crystallizer, bese ukhipha ukusakaza okuqinile (okuqinile). Esinye isiphetho segumbi lokulingisa sisetshenziselwa ukuthola ukulingisa kwanoma ibuphi ubude, umumo, nobude obuthile.

Umshini wokuphonsa oqhubekayo uthuthukiswe ngokukhethekile ukuphonsa amapuleti e-alloy, imigoqo eyindilinga, imigoqo yesikwele, imigoqo engunxande, amashubhu ayindilinga, nezinye izimo zegolide, i-K-igolide, isiliva, nezinye izinsimbi eziyigugu. Isetshenziswa kakhulu ekucutshungulweni kwensimbi, ukucutshungulwa kobucwebe begolide obungaqediwe, izitshalo zokuncibilikisa insimbi, izitshalo zokucubungula inqubo yensimbi, izikhungo zocwaningo, amalabhorethri, izikole, ukuncibilikisa insimbi eyigugu nezinye izimboni. Ukuthuthukisa umkhiqizo kanye nekhwalithi kuyimishini edingekayo yokukhiqiza nokukhiqizwa kwezinto zensimbi, kanye nokuthuthukiswa kwemikhiqizo yezimboni ze-metallurgical.

Imishini yokuphonsa eqhubekayo nayo ihlukaniswe yaba i-vacuum ne-non vacuum, uyazi? Kukhona futhi umehluko omkhulu phakathi kwazo, futhi ngizokwethula ngokuningiliziwe ngokulandelayo.

Okokuqala, kunesakhiwo somshini esiphezulu. Isakhiwo se-vacuum sidinga izinga eliphezulu le-vacuum kusilinda sokuphonsa. Ukwengeza, ipompo ye-vacuum idinga ukungezwa. Imishini yokukhipha i-vacuum eqhubekayo ayinazo lezi zidingo ezimbili.

Okwesibili, ngokombono wokusebenza. I-vacuum idinga ukuqhutshwa komlilo ngesithando somlilo, okusho ukuthi impahla yesithando somlilo iphonswa kanye isikhathi ngasinye, futhi ngemva kokuqeda yonke imisebenzi yokudweba, umjikelezo wesibili wokusebenza uqhutshwa futhi. Le ndlela yokusebenza ayisheshi futhi inzima. Ukusebenza kwemishini engeyona ivacuum kungaba lula kakhulu ngokuncibilika kanyekanye, kuholele phansi, kanye nokwengeza izinto.

Okwesithathu, umehluko phakathi kwemikhiqizo yokuphonsa kanye nemikhiqizo ye-vacuum okuqukethwe komoyampilo ophansi, ofanele ukucutshungulwa komkhiqizo wezimboni, njengezintambo zokubopha, izingxenye ze-elekthronikhi, kanye nemikhiqizo engeyona i-vacuum. Kodwa-ke, uma okuqukethwe komoyampilo kuphezulu kunemikhiqizo yevacuum, ukuminyana komkhiqizo kuyefana, okuwenza into ekhethwayo yokukhiqiza ubucwebe enezidingo zekhwalithi ephezulu.

Okwesine, ukusetshenziswa kwegesi yokuzivikela kubhekisela ku-nitrogen noma i-argon gas, futhi eyodwa kuphela yazo ingasetshenziswa. Umsebenzi oyinhloko ukunciphisa ukulahlekelwa okubangelwa i-oxidation yensimbi. Yomibili imishini yokukhipha i-vacuum kanye nemishini yokukhipha i-vacuum ifakwe izici zegesi yokuvikela.
