Ulwakhiwo lweflux kufuneka lwenze kube lula lo msebenzi ngaphandle kokuxhasa iimpendulo zesibini okanye ukutshintsha kakubi i-viscosity. Le ndima imbini-ukususa izinto ezifakiweyo ngelixa kugcinwa ukuhamba-kubalulekile kwimveliso yentsimbi ephezulu.
Impembelelo kuMgangatho woMphezulu kunye nesantya sokuSebenza
Ukusebenza kakuhle kwe-mold flux kumisela ngokuthe ngqo ukugqitywa komphezulu we-billet, i-bloom, okanye i-slab. Ulawulo olufanayo lokudluliselwa kobushushu kunye nokuthambisa luqinisekisa ukukhula okulinganayo kwegobolondo, kunciphisa amabala okushukuma kunye nokuqhekeka. Izifundo zesikali sezityalo ziqinisekisa ukuba iiparameter ze-flux ezilungisiweyo zinika iindawo ezithambileyo kunye neziphene ezimbalwa, ingakumbi kwisantya sokuphosa esingaphezulu kwe-3 m/min.
Ukuphuculwa kwesantya sokusebenza kwinkqubo yokubumba eqhubekayo kuxhomekeke ekuqhubekeni kolawulo lokuhamba kwesikhunta. Ngesantya esiphezulu, ukunyibilika okungaphelelanga okanye okungaguqukiyo, ukuthambisa okwaneleyo, okanye ubushushu obuphezulu bendawo kunokubangela ukusilela okukhulu komphezulu okanye ukuqhekeka kwegobolondo. Isantya sonyusa uxinzelelo ngakumbi kubudlelwane phakathi kweprofayili yokuhamba kobushushu, ukuzinza kokuthambisa, kunye nolawulo lweziphene, okuqinisa imfuneko yolawulo oluqinileyo lwepropati yokuhamba kwesikhunta.
Ukuphosa ngesantya esiphezulu: Imingeni ekukhetheni nasekulawuleni i-Flux
Ukuphoswa okuqhubekayo okukhawulezayo kwandisa imingeni ekulawuleni ukuziphatha kokuhamba komoya:
- Ukudluliselwa kobushushu okungazinzanga:Ukuqina ngokukhawuleza kwandisa i-thermal gradients, nto leyo ebeka emngciphekweni ukwakheka kweqokobhe elingalinganiyo okanye ukuqhekeka kwendawo ukuba iipropati ze-flux azinamandla ngokwaneleyo okanye aziphenduli ngokwaneleyo.
- Ulawulo lwekristale:Amanqanaba okuphosa ngokukhawuleza anokuphazamisa ibhalansi yekristale/yeglasi ecetywayo kumaleko we-slag oqinileyo. Ukukristaleka okukhawulezayo kakhulu kunokubamba iileya zokufuduka, kunyuse ukumelana nobushushu ngaphaya kweyona ndlela ifanelekileyo, kubangele ukuqhekeka kwangaphakathi. Ukukristaleka okucothayo kakhulu kubangela ukuthambisa okugqithisileyo kunye nokulahleka kobushushu okugqithisileyo, okwandisa amanqaku okushukuma kunye nokudodobala.

- Ukuthintela i-Oxidation:Ukwanda kokushukuma kunye nokuguquguquka kwamanqanaba esinyithi kukhuthaza ukudibana komoya, okufuna ukushukuma okuzinzileyo kakhulu kokuxutywa kunye neempawu zokugubungela ukunyibilika ngokukhawuleza.
- Ukufunxwa kokubandakanywa:Amanani aphezulu okulahla inkunkuma afuna ukujikeleza okukhawulezayo ukuze kugcinwe ukubanjwa nokususwa okuqhubekayo ngaphandle kokuvumela izinto ezifakiweyo ukuba ziphume.
Amava emizi-mveliso abonisa ukuba iipropati ezifanai-viscosity ye-flux, ubushushu bekristale, kunye nokumelana notshintsho lwekhemistri kufuneka kulawulwe kwaye kujongwe rhoqo. Iindlela zokukwenza oku ziquka ukuchazwa kwexesha langempela kusetyenziswa izixhobo zokulinganisa uxinano lolwelo eziphambili ezifana neLonnmeter ultrasonic density meter okanye iLonnmeter tuning fork density meter, okuvumela ulawulo oluhambelanayo lwe-flux layer dynamics.
Ngamafutshane, ukufezekisa uphuculo oluqhubekayo lwenkqubo yokubumba—ingakumbi ngokubhekiselele kulawulo lomgangatho kunye nesantya sokusebenza—kuxhomekeke kwiipropati eziqinileyo zokufudumeza umngundo kunye nolawulo: ukulinganisela ukudluliselwa kobushushu, ukuthambisa, ukuthintela i-oxidation, kunye nokufunxwa kokufakwa kuzo zonke iiklasi zentsimbi ezahlukeneyo kunye neemeko zokubumba.
Iipropati ezibalulekileyo zeMold Flux ukuze kusebenze kakuhle
Ukujikeleza komgubo kubalulekile ekuphuculeni inkqubo yokubumba rhoqo kunye nolawulo lomgangatho. Iimpawu zayo ezibonakalayo zimisela ngokuthe ngqo ukusebenza kweendlela zokulawula ukudluliselwa kobushushu kwi-steel casting, iindlela zokuthambisa umgubo, kunye nokuthintela iziphene.
Ukuqina: Ukuthambisa, Ukudlulisa Ubushushu, kunye nokuthintela ukuqhekeka
Ii-viscosity ye-mold fluxilawula ukuthambisa phakathi kweqokobhe lentsimbi kunye ne-mold yobhedu. I-viscosity efanelekileyo iqinisekisa ifilimu yokuthambisa ezinzileyo, efunekayo ukunciphisa ukungqubana phakathi kwe-billet kunye ne-mold kunye nokuthintela i-oxidation yesibini kwintsimbi enyibilikisiweyo. I-viscosity ephantsi inyusa ukuthambisa, okunciphisa umngcipheko wokuqhekeka okude ngokuthintela ukudibana ngqo kwe-shell-mold kunye nokukhula kwe-shell okungalinganiyo. Nangona kunjalo, i-viscosity kufuneka ilawulwe ngononophelo: ukuba iphantsi kakhulu, ukudluliselwa kobushushu obugqithisileyo kunokubangela ukuqhekeka komphezulu; ukuba iphezulu kakhulu, ukuthambisa akwanelanga, okukhokelela ekunamatheleni kwe-shell okanye ukwakheka kwe-crack.
Izongezo ezifana ne-MgO zisebenza njengeziphazamisi zenethiwekhi kwi-melt, zinciphisa amandla okusebenza kwaye ziguqula isakhiwo se-melt. Oku kuphumela ekunciphiseni i-viscosity, kuphucula ukuziphatha kwe-lubrication kunye ne-crystallization kwaye kuvelisa ukupholisa okufanayo kwi-casting eqhubekayo. Umzekelo, ukulungisa i-viscosity kwi-casting ye-slab encinci ekhawulezayo kukhokelele ekunciphiseni okukhulu kwiziphene zomphezulu, kunye ne-fluxes ephuculweyo ekhokelela ekuphuculeni ukukhula kwe-shell kunye nokuqhekeka okuncinci komphezulu.
Izinga lokunyibilika kunye nobushushu: Ukugqunywa ngokukhawuleza kwesikhunta kunye nolawulo lobushushu
Izinga lokunyibilika kunye nobushushu bumisela ukuba isikhunta sigqunywa ngokukhawuleza kangakanani lulwelo. Ukugqunywa kwesikhunta okukhawulezayo nokulinganayo kubalulekile ekulawuleni ukukhupha ubushushu kunye nokubonelela nge-lubrication kwizigaba zokuqala zokwakheka kweqokobhe. Kwimisebenzi yokusika ngesantya esiphezulu (≥3 m/min), i-flux yesikhunta kufuneka ifikelele kumaqondo obushushu okunyibilika angaphantsi kwe-1000°C kwaye igqibezele ukunyibilika kwimizuzwana engama-41 ukugcina ukusebenza kakuhle kwe-cast kunye nokuthintela iziphene zomphezulu.
Izinto ezingaphandle kobushushu (umz., i-CaSi okanye i-Si) kunye nokusasazwa kobukhulu bee-particles ezilungiselelwe wena zikhawulezisa izinga lokunyibilika ngokubonelela ngobushushu obongezelelweyo bokusabela.
