Sehlooho: Ho utloisisa ts'ebetso ea arapameng vacuum casterbakeng sa litšepe tsa bohlokoa le li-alloys

Tšebeliso ea theknoloji e tsoetseng pele e bohlokoa haholo ha ho etsoa litšepe tsa boleng bo holimo le li-alloys.Horizontal vacuum continuous casting mochini ke theknoloji e fetolang ka botlalo ts'ebetso ea tlhahiso.Thepa ena e ncha e bapala karolo ea bohlokoa tlhahisong ea litšepe tse fapaneng tsa bohlokoa le lialloi, e fana ka boleng bo ikhethang le bokhabane.Ho blog ena, re tla shebana le ts'ebetso e rarahaneng ea "vacuum vacuum continuous caster", re lekola ts'ebetso ea eona le lits'ebetso tsa bohlokoa tse amehang tlhahisong ea litšepe tsa bohlokoa le lialloys.

Tshebetso ya tshekaletsengvacuum e tsoelang pele ho lahlela mochinie qala ka ho lokisa lisebelisoa tse tala.Litšepe tsa bohlokoa le li-alloys li khethiloe ka hloko 'me li lokiselitsoe mokhoa oa ho lahla.Lisebelisoa tse tala li qhibilihisoa ka sebōping sa mocheso o phahameng ho fihlela boemo bo nepahetseng ba mokelikeli bakeng sa ho lahlela.Hang ha tšepe e qhibilihisitsoeng e fihla mochesong o lakatsehang le ho tsitsa, e ka fetisetsoa phaposing ea mochini ea ho akhela.

Ha tšepe e qhibilihisitsoeng e kenngoa ka kamoreng ea ho lahla, tikoloho ea vacuum e phetha karolo ea bohlokoa ho netefatsa boleng ba mokhoa oa ho lahlela.Ho ba sieo ha moea le litšila tse ling ka phaposing ea vacuum ho thusa ho thibela oxidation le tšilafalo ea tšepe e qhibilihisitsoeng, e hlahisang sehlahisoa sa boleng bo holimo.Tikoloho ena ea vacuum e boetse e lumella taolo e betere ea ts'ebetso ea ho pholisa, e nolofalletsang tlhahiso ea li-castings tse nepahetseng le tse tšoanang.

Kamore ea ho tšela ea mochini oa vacuum o sa khaotseng oa ho lahla o na le letoto la mekhoa e nepahetseng ea ho pholisa.Mekhoa ena e etselitsoe ho pholisa tšepe e qhibilihisitsoeng ka potlako ha e feta ka kamoreng, kahoo e khothalletsa mokhoa oa ho tiisa.Ka ho laola lebelo la ho pholile, mochine o ka hlahisa li-castings tse nang le thepa e khethehileng ea metallurgic, ho netefatsa litšobotsi tse lakatsehang tsa sehlahisoa sa ho qetela.

E 'ngoe ea likarolo tse ka sehloohong tsa li-caster tse sa khaotseng tsa vacuum ke bokhoni ba ho hlahisa li-castings tse telele tse telele.Ho fapana le mekhoa e tloaelehileng ea ho lahla moo bolelele ba ho lahla bo ka fokotsoang, li-vacuum casters tse otlolohileng li ka hlahisa bolelele bo bolelele ba tšepe e entsoeng ka tšepe.Bokhoni bona bo molemo ka ho khetheha tlhahisong ea litšepe tsa bohlokoa le lihlahisoa tsa alloy, tseo hangata li hlokang nako e telele, e ts'oanang ea li-castings bakeng sa ts'ebetso e tsoelang pele le tlhahiso.

Taolo e nepahetseng ea lebelo la ho lahla ke karolo e 'ngoe ea bohlokoa ea ts'ebetso ea mochini.Ka ho laola lebelo la tšepe e qhibilihisitsoeng ka kamoreng ea ho lahla, bahlahisi ba ka finyella boholo bo lakatsehang le thepa.Boemo bona ba taolo bo bohlokoa bakeng sa ho hlahisa litšepe tsa bohlokoa tsa boleng bo holimo le lihlahisoa tsa alloy, moo ho nepahala le ho tsitsa ho leng bohlokoa.

Ntle le ts'ebetso ea ho lahla ka boeona, "vacuum continuous caster" e otlolohileng e boetse e sebelisa lits'ebetso tse tsoetseng pele tsa ho lekola le ho laola.Litsamaiso tsena li lumella basebelisi ho lekola ka hloko likarolo tse fapaneng tsa ts'ebetso ea ho lahla, ho kenyelletsa mocheso, sekhahla sa ho pholisa le lebelo la ho lahla.Ka ho tsoela pele ho beha leihlo le ho lokisa liparamente tsena, bahlahisi ba ka netefatsa boleng bo tsitsitseng ba ho lahlela bo fihlelang litlhoko tse thata tsa tšepe ea bohlokoa le tlhahiso ea alloy.

Mochini o sa khaotseng oa vacuum o otlolohileng o boetse o na le lisebelisoa tse tsoetseng pele tsa ho ntša le ho itšeha.Hang ha tšepe e entsoeng ka ho qhibilihisoa e tiea hore e be ntho e sa khaotseng, mechine e ka ntša mokelikeli ka ho toba ka phaposing ebe e e khaola ho fihlela bolelele bo hlokahalang.Ts'ebetso ena e ikemetseng e netefatsa tlhahiso e ntle ea li-castings tse tšoanang, tsa boleng bo holimo tse itokiselitseng ts'ebetso le tlhahiso e tsoelang pele.

Ho feto-fetoha ha li-vacuum casters ho etsa hore e be tse loketseng bakeng sa tlhahiso ea mefuta e mengata ea litšepe tsa bohlokoa le li-alloys.Ebang ke khauta, silevera, platinum kapa li-alloys tse khethehileng, mochine o ka ikamahanya le mefuta e fapaneng ea lisebelisoa 'me oa hlahisa li-castings ka mokhoa o nepahetseng le o tsitsitseng.Ho tenyetseha hona ho bohlokoa ho fihlela litlhoko tse fapaneng tsa liindasteri tse itšetlehileng ka tšepe ea boleng bo holimo le lihlahisoa tsa alloy.

Ka kakaretso, ts'ebetso ea "vacuum vacuum" e tsitsitseng e tsoelang pele bakeng sa litšepe tsa bohlokoa le li-alloys e kenyelletsa letoto la lits'ebetso tse rarahaneng tse hlophisitsoeng ka hloko ho netefatsa tlhahiso ea li-castings tsa boleng bo holimo.Ho tloha ho lokisoeng ha lisebelisoa tse tala ho ea ho taolo e nepahetseng ea li-parameter tsa ho lahla, mochine ona o emela tlhōrō ea mekhoa e mecha ea theknoloji tšimong ea ho lahla tšepe.Bokhoni ba eona ba ho hlahisa li-castings tse telele tsa nako e telele ka ho nepahala ho ikhethang le thepa ea metallurgic e etsa hore e be sesebelisoa sa bohlokoa bakeng sa tlhahiso ea boleng bo phahameng ba tšepe le lihlahisoa tsa alloy.Ha theknoloji e ntse e tsoela pele, li-vacuum tse tsoelang pele li tla bapala karolo ea bohlokoa ho bopeng bokamoso ba tšepe ea bohlokoa le tlhahiso ea alloy.
