Isithando somlilo se-VIM-DS Vacuum Directional Solidification

Isithando somlilo se-VIM-DS esibhekisele kwi-Vacuum Directional Solidification Furnace Umfanekiso obonisiweyo

Intshayelelo yomzekelo

Isithando sokuqinisa esibhekisa kwicala le-VIM-DS songeza imisebenzi emibini emikhulu kwisithando sokunyibilikisa i-vacuum esiqhelekileyo: inkqubo yokufudumeza i-mold shell kunye nenkqubo yokulawula ukuqina ngokukhawuleza kwe-alloy enyibilikisiweyo.

Esi sixhobo sisebenzisa ubushushu bokungenisa obuphakathi ukuze sinyibilikise izinto phantsi kweemeko zokhuseleko lwe-vacuum okanye igesi. Izinto ezinyibilikisiweyo emva koko zigalelwa kwi-crucible enesimo esithile kwaye zifudunyezwe, zibanjwe, kwaye zilawulwe bubushushu yi-resistance okanye i-induction heating furnace (enesikrini esidibeneyo). I-crucible emva koko yehliswa kancinci kwindawo ene-gradient enkulu yobushushu, okuvumela ukukhula kwekristale ukuba kuqale ukusuka ezantsi kwe-crucible kwaye kancinci kancinci kunyuke. Le mveliso ifanelekile kakhulu ukuvelisa ii-alloys zobushushu obuphezulu, iikristale ze-optical, iikristale ze-scintillation, kunye neekristale ze-laser.

Iithegi zeMveliso

Izicelo:

Sisixhobo esilungileyo sokulungiselela iiblade zenjini ye-turbine ezikumgangatho ophezulu, iiblade ze-turbine zegesi kunye nezinye izinto ezidityanisiweyo ezinezakhiwo ezikhethekileyo, kunye nokulungiselela iindawo zekristale enye yee-alloys ezisekwe kwi-nickel, i-iron kunye ne-cobalt ezisekwe kwi-ultra-high temperature.

Iingenelo zeMveliso:

Ulwakhiwo oluthe nkqo olunamagumbi amathathu, imveliso eqhubekayo kancinci; igumbi eliphezulu ligumbi lokunyibilikisa nokuphosa, kwaye igumbi elingaphantsi ligumbi lokulayisha nokukhupha isikhunta; lahlulwe yivalvu yevacuum evala kakhulu.

Iindlela ezininzi zokutya ziqinisekisa ukongezwa kwesibini kwezinto ze-alloy, okuvumela ukunyibilika kunye nokufakwa kwe-semi-continuous.

Injini elawula isantya esiguquguqukayo esisemgangathweni ophezulu ilawula ngokuchanekileyo isantya sokuphakamisa isikhunta se-ingot.

Ukufudumeza iqokobhe le-mold kungaba kukuxhathisa okanye ukufudumeza ngokungenisa, okuvumela ulawulo lweendawo ezininzi ukuqinisekisa i-thermal gradient ephezulu efunekayo.

Isixhobo sokuqinisa ngokukhawuleza singakhethwa kwisitya esipholileyo esimanzi esiphantsi okanye kwimbiza yetini epholileyo ejikelezileyo epholiswe ngeoyile.

Lonke umatshini ulawulwa yikhompyutha; inkqubo yokuqinisa izinto ingalawulwa ngokuchanekileyo.
