Lisebelisoa tsa likarolo tsa Motlakase
Kenyelletso ea Sehlahisoa
Ha ho etsoa likarolo tsa aluminium tse tsoetseng pele ka ho fetesisa, khetho ea thepa e bohlokoa haholo.Ke ka lebaka leo k'hamphani ea rona e sebelisang li-ingots tsa aluminium tsa boleng bo holimo feela, tse kang A356.2/AlSi7Mg0.3 e tloaelehileng.Matla a babatsehang le ho tšoarella ha li-ingots tsena li tiisa hore likarolo tseo re li hlahisang li na le bophelo bo bolelele ba tšebeletso.Re reka thepa ka hloko ho tsoa ho barekisi ba tsebahalang ho netefatsa boleng ba eona bo botle.
Tlhokomelo ea rona e hlokolosi ea lintlha e boetse e fetela ts'ebetsong ea ho felisoa ha thepa.Nakong ena e mahlonoko, laola mocheso ka thata ho netefatsa maemo a nepahetseng a ho lahla.Ntle le moo, re ekelitse palo e loketseng ea li-additives ho ntlafatsa ts'ebetso le ts'ebeliso ea likarolo tsa aluminium tse entsoeng.Li-additives tsena li thusa ho ntlafatsa thepa ea mochini, joalo ka boima bo eketsehileng le ho hanyetsa kutu.
E 'ngoe ea litšobotsi tse ka sehloohong tsa likarolo tsa rona tsa aluminium ke mokhoa oa ho hloekisa.Ka mor'a hore thepa e qhibilihe, re tsoela pele ho hloekisa aluminium ea metsi ka ho sebelisa khase ea argon e hloekileng haholo.Mokhoa ona oa ho hloekisa o felisa litšila le ho ntlafatsa boleng ba kakaretso ea sehlahisoa sa ho qetela.Tšebeliso ea argon ea bohloeki bo phahameng e tiisa hore likarolo tsa rona tsa aluminium li finyella litekanyetso tse phahameng ka ho fetisisa tsa indasteri le litebello tsa bareki.
E le ho boloka boitlamo ba rona ba boleng, lisebelisoa tsa rona tsa tlhahiso li khomarela mehato e tiileng ea ho laola boleng.Re sebelisa lisebelisoa tsa morao-rao 'me re hira sehlopha sa basebetsi ba nang le litsebo tse phahameng tsa theknoloji ho beha leihlo mohato ka mong oa ts'ebetso ea tlhahiso.Sena se re thusa ho lula re fana ka likarolo tsa aluminium tse nang le sekoli le ho kopana le mamello e tiileng e hlokoang ke bareki.
Likarolo tsa rona tsa aluminium tsa cast li fana ka melemo e mengata bakeng sa lits'ebetso tse fapaneng.Matla a tlhaho le boima bo bobebe ba aluminium bo etsa hore e be khetho e nepahetseng bakeng sa lisebelisoa tsa motlakase tsa likoloi, lisebelisoa tsa metjhini ea temo, lisebelisoa tsa motlakase tse lebelo le phahameng, le lisebelisoa tsa motlakase tsa marang-rang.Likarolo tsena li na le botšepehi bo botle ba sebopeho 'me li khona ho mamella meroalo e boima le maemo a feteletseng a ts'ebetso.
