Kugadzira yakanyungudutswa yemhangura graphite crucible uchishandisa inotonhora isostatic kudzvanya: Yepamberi tekinoroji inotungamira iyo indasitiri kune hurefu hutsva.

Tekinoroji yekugadzira yemagraphite crucibles yekunyungudutsa mhangura iri kuita shanduko. Kuita uku kunoshandisa nzira yepasirese inotonhora isostatic yekutsikirira uye inoumbwa pasi pekumanikidzwa kwakanyanya kwe600MPa kuve nechokwadi chekuti chimiro chemukati checrucible chiri yunifomu uye isina hurema uye ine simba rakanyanya. Iyi innovation haingogadziri kushanda kwe crucible, asi inoitawo kubudirira kukuru mukuchengetedza simba uye kuchengetedza kwezvakatipoteredza.

Zvakanakira kutonhora isostatic kudzvanya
Chimiro chemukati chakafanana uye chisina kukanganisa
Pasi pe-high-pressure molding, chimiro chemukati chemhangura-graphite crucible chakanyanya kufanana pasina kukanganisa. Izvi zvakasiyana zvachose nenzira dzechinyakare dzekucheka. Nekuda kwekudzvinyirira kwakaderera, nzira dzechinyakare zvinotungamira kune mukati memukati zvikanganiso zvinokanganisa simba rayo uye kupisa conductivity.

High simba, mutete crucible rusvingo
Iyo inotonhora isostatic yekutsikirira nzira inovandudza zvakanyanya kusimba kweiyo crucible pasi pekumanikidzwa kwakanyanya. Iyo yakakura simba inobvumira madziro anorovera kuti aitwe matete, nekudaro achiwedzera kupisa conductivity uye kuderedza kushandiswa kwesimba. Kuenzaniswa nemakororo echinyakare, iyi mhando nyowani yecrucible inonyanya kukodzera kugadzirwa kwakanaka uye zvinodiwa zvekuchengetedza simba.

Yakanakisa thermal conductivity uye yakaderera simba rekushandisa
Iyo yakakwira simba uye yakaonda-yakakomberedzwa chimiro cheyakanyungudutswa yemhangura graphite crucibles inokonzeresa zviri nani kupisa conductivity zvichienzaniswa neyakajairwa crucibles. Kuvandudza kupisa kunoreva kuti kupisa kunogona kufambiswa zvakaenzanirana uye nekukurumidza panguva yekunyungudutsa kwealuminium alloys, zinc alloys, nezvimwewo, nekudaro kuderedza kushandiswa kwesimba nekuvandudza kugona kwekugadzira.

Kuenzanisa nenzira dzechinyakare dzekugadzira
Kukanganisa kwekucheka nzira
Mazhinji emagetsi anogadzirwa emu graphite crucibles anogadzirwa nekucheka uyezve sintering. Iyi nzira inoguma nekusaenzana, kukanganisa, uye kuderera-kusimba kwemukati zvivakwa nekuda kwekuderera kudzvinyirira. Mukuwedzera, ine urombo hwekupisa conductivity uye kushandiswa kwesimba kwakanyanya, zvichiita kuti zviome kuzadzisa zvinodiwa neindasitiri yemazuva ano yekushanda kwepamusoro uye kuchengetedza simba.

Zvakaipa zvevatevedzeri
Vamwe vagadziri vanotevedzera inotonhora isostatic yekutsikirira nzira yekugadzira crucibles, asi nekuda kwekusakwana kwekugadzira kumanikidza, mazhinji acho anogadzira silicon carbide crucibles. Aya macrucibles ane madziro akakora, kushomeka kwekushisa kwemhepo, uye kushandiswa kwesimba kwakanyanya, kuri kure neiyo chaiyo yakanyungudutswa yemhangura graphite crucibles inogadzirwa nekutonhora isostatic kudzvanya.

Misimboti yehunyanzvi uye mashandisirwo
Mukuita kunyungudutsa kwealuminium uye zinc alloys, iyo oxidation kuramba uye kupisa kwekupisa kweiyo crucible zvinhu zvakakosha. Macrucibles anogadzirwa uchishandisa inotonhora isostatic yekutsikirira nzira inoisa yakanyanya kukoshesa pane oxidation kuramba uchidzivirira iyo yakashata mhedzisiro yefluoride-ine fluxes. Aya ma crucibles anochengetedza kuita kwakanakisa pakupisa kwakanyanya pasina kusvibisa simbi, zvakanyanya kuvandudza kusimba.

Kushandiswa mualuminium alloy smelting
Graphite crucible inoita basa rakakosha mukunyunguduka kwealuminium alloys, kunyanya mukugadzirwa kwemafa castings uye castings. Tembiricha yekunyunguduka yealuminium alloy iri pakati pe700°C ne750°C, inovawo tembiricha yetembiricha apo graphite iri nyore oxidized. Naizvozvo, ma graphite crucibles anogadzirwa neinotonhora isostatic yekutsikirira nzvimbo yakakosha yekusimbisa oxidation kuramba kuti ive nechokwadi chekuita kwakanaka pakupisa kwepamusoro.

Yakagadzirirwa nzira dzakasiyana dzekunyungudika
Graphite crucible inokodzera nzira dzakasiyana-siyana dzekunyungudutsa, kusanganisira imwe-furnace kunyunguduka uye kunyunguduka pamwe chete nekuchengetedza kupisa. Kune aruminiyamu alloy castings, iyo crucible dhizaini inoda kusangana nezvinodiwa zvekudzivirira kunyudzwa kweH2 uye kusanganiswa kweoxide, saka iyo yakajairwa crucible kana yakakura-muromo bhodhoro-yakaita crucible inoshandiswa. Mumavira epakati ekunyungudutsa, masimbi anotsenhama anowanzo shandiswa kudzoreredza tsvina inonyungudutsa.

Kuenzanisa kwemaitiro ekuita
High density uye thermal conductivity
Kuwanda kwema graphite crucibles anogadzirwa nekutonhora isostatic kudzvanya kuri pakati pe2.2 ne2.3, inova ndiyo yakanyanya density pakati pemacrucibles munyika. Iyi yakakwira density inopa crucible optimal thermal conductivity, zvirinani zvakanyanya kupfuura mamwe mabhureki emacrucibles.

Glaze uye corrosion resistance
Iyo pamusoro peyakanyungudutswa yealuminium graphite crucible yakafukidzwa nezvikamu zvina zveyakakosha glaze coating, iyo, yakasanganiswa nedense yekuumbwa zvinhu, inonatsiridza zvakanyanya kushora kweiyo crucible uye inowedzera hupenyu hwesevhisi. Kusiyana neizvi, zvimedu zvemumba zvinongova nesamende yakasimbiswa pamusoro pepamusoro, iyo inokuvadza nyore nyore uye inokonzera nguva isati yasvika oxidation ye crucible.

Kuumbwa uye thermal conductivity
Iyo yakanyungudutswa yemhangura graphite crucible inoshandisa yakasikwa graphite, iyo ine yakanakisa yekupisa conductivity. Kusiyana neizvi, magirafu emumba anoshandisa magirafu ekugadzira, kuderedza zvinyorwa zve graphite kuderedza mari, uye kuwedzera huwandu hwevhu hwekuumba, saka kupisa kwekushisa kunoderedzwa zvakanyanya.

Packaging uye nzvimbo dzekushandisa
Packing
Yakanyungudutswa yemhangura ye graphite crucible inowanzo unganidzwa uye inoputirwa netambo yemashanga, iri nzira iri nyore uye inoshanda.

Kuwedzerwa kwenzvimbo dzekushandisa
Nekuenderera mberi kwekufambira mberi kwetekinoroji, minda yekushandisa yemagraphite crucibles inoramba ichiwedzera. Kunyanya mukugadzirwa kwealuminium alloy die castings uye castings, magirafu crucibles zvishoma nezvishoma ari kutsiva echinyakare mapoto esimbi kuti asangane nezvinodiwa zvekugadzira zvemhando yepamusoro zvikamu zvemotokari.

mukupedzisa
Iko kushandiswa kweinotonhora isostatic yekutsikirira nzira kwaunza kushanda uye kugona kwemhangura-graphite crucible kunyungudutsa kune imwe nhanho. Ingave iyo yakafanana, simba kana kupisa conductivity yemukati chimiro, iri nani zvakanyanya pane echinyakare nzira dzekugadzira. Nekushandiswa kwakapararira kweiyi tekinoroji yepamusoro, kudiwa kwemusika kwemagraphite crucibles kucharamba kuchiwedzera, kutyaira iyo indasitiri yese kune remangwana rinoshanda uye rine hushamwari.
