Kupanga zitsulo zamkuwa zamkuwa za graphite pogwiritsa ntchito makina ozizira a isostatic: Ukadaulo wapamwamba umatsogolera makampani kupita kumalo atsopano.

Ukadaulo wopangira zida za graphite zosungunula mkuwa ukuyenda bwino. Njirayi imagwiritsa ntchito njira yapadziko lonse lapansi yozizira kwambiri ya isostatic ndipo imapangidwa movutikira kwambiri 600MPa kuwonetsetsa kuti mkati mwa crucible ndi yunifolomu komanso yopanda chilema ndipo imakhala ndi mphamvu zambiri. Kusintha kumeneku sikungowonjezera ntchito ya crucible, komanso kumapangitsa kuti pakhale chitukuko chachikulu pakusunga mphamvu ndi kuteteza chilengedwe.

Ubwino wa kukanikiza kozizira kwa isostatic
Mapangidwe amkati ndi ofanana komanso opanda chilema
Pansi pa makina othamanga kwambiri, mawonekedwe amkati a copper-graphite crucible ndi ofanana kwambiri popanda chilema chilichonse. Izi zikusiyana kwambiri ndi njira zachikhalidwe zodulira. Chifukwa cha kupanikizika m'munsi, njira zachikhalidwe zimatsogolera ku zolakwika zamkati zomwe zimakhudza mphamvu zake ndi matenthedwe.

Mkulu mphamvu, woonda crucible khoma
Njira yozizira ya isostatic imapangitsa kuti mphamvu ya crucible ikhale yolimba kwambiri. Mphamvu zazikuluzikulu zimalola kuti makoma a crucible akhale ochepa kwambiri, motero amawonjezera kutentha kwa matenthedwe ndi kuchepetsa kugwiritsa ntchito mphamvu. Poyerekeza ndi ma crucibles achikhalidwe, mtundu watsopano wa crucible ndi woyenera kupanga bwino komanso zofunikira zopulumutsa mphamvu.

Wabwino matenthedwe madutsidwe ndi otsika mphamvu mowa
Kulimba kwamphamvu komanso mipanda yopyapyala yopangidwa ndi mipanda yamkuwa yamkuwa ya graphite imapangitsa kuti matenthedwe azikhala bwino kwambiri poyerekeza ndi ma crucibles wamba. Kupititsa patsogolo matenthedwe matenthedwe kumatanthauza kuti kutentha kumatha kusamutsidwa mofanana komanso mofulumira panthawi yosungunula ma aluminiyamu, ma aloyi a zinki, ndi zina zotero, potero kuchepetsa kugwiritsira ntchito mphamvu ndi kupititsa patsogolo kupanga.

Poyerekeza ndi njira zopangira zachikhalidwe
Zochepa za njira zodulira
Zambiri mwazitsulo za graphite zomwe zimapangidwa m'nyumba zimapangidwa ndi kudula kenako ndi sintering. Njirayi imapangitsa kuti zipangidwe zamkati zikhale zosagwirizana, zolakwika, komanso zochepa chifukwa cha kupanikizika kochepa. Kuphatikiza apo, imakhala ndi ma conductivity otsika amafuta komanso kugwiritsa ntchito mphamvu zambiri, zomwe zimapangitsa kuti zikhale zovuta kukwaniritsa zofunikira zamakampani amakono kuti azigwira bwino ntchito komanso kupulumutsa mphamvu.

Kuipa kwa otsanzira
Opanga ena amatsanzira njira yozizira ya isostatic kuti apange crucibles, koma chifukwa cha kusakwanira kopanga, ambiri aiwo amapanga silicon carbide crucibles. Ma crucibles awa ali ndi makoma okhuthala, kusayenda bwino kwamafuta, komanso kugwiritsa ntchito mphamvu zambiri, zomwe zili kutali ndi ma graphite amkuwa osungunuka omwe amapangidwa ndi kuzizira kwa isostatic.

Mfundo zamakono ndi ntchito
Pakusungunula kwa aluminiyamu ndi ma aloyi a zinc, kukana kwa okosijeni ndi kutenthetsa kwa crucible ndizofunikira kwambiri. Ma Crucibles opangidwa pogwiritsa ntchito njira yozizira ya isostatic pressing imatsindika kwambiri kukana kwa okosijeni ndikupewa zovuta zomwe zimakhala ndi fluoride. Ma crucibles awa amakhalabe ndi ntchito yabwino pa kutentha kwakukulu popanda kuwononga zitsulo, zomwe zimapangitsa kuti zikhale zolimba.

Kugwiritsa ntchito aluminium alloy smelting
Graphite crucible imagwira ntchito yofunika kwambiri pakusungunuka kwa ma aloyi a aluminiyamu, makamaka popanga ma castings ndi ma castings. Kutentha kosungunuka kwa aluminiyamu alloy ndi pakati pa 700 ° C ndi 750 ° C, komwenso ndi kutentha komwe graphite imapangidwa mosavuta. Chifukwa chake, ma graphite crucibles opangidwa ndi kuzizira kwa isostatic kukanikiza amaika kutsindika kwapadera pa kukana kwa okosijeni kuti awonetsetse kuti akugwira ntchito kwambiri pakutentha kwambiri.

Zapangidwira njira zosiyanasiyana zosungunuka
Graphite crucible ndi yoyenera njira zosiyanasiyana zosungunulira, kuphatikizapo ng'anjo yamoto imodzi ndi kusungunula pamodzi ndi kusunga kutentha. Pazitsulo za aluminiyamu, mapangidwe a crucible ayenera kukwaniritsa zofunikira kuti ateteze kuyamwa kwa H2 ndi kusakaniza kwa okusayidi, kotero kuti crucible yokhazikika kapena crucible yooneka ngati mbale yapakamwa imagwiritsidwa ntchito. M'ng'anjo zapakati zosungunula, ng'anjo zopendekeka zimagwiritsidwa ntchito kukonzanso zinyalala zosungunula.

Kufananiza kwa magwiridwe antchito
Mkulu kachulukidwe ndi matenthedwe madutsidwe
Kuchulukana kwa ma graphite crucibles opangidwa ndi kukanikiza kozizira kwa isostatic kuli pakati pa 2.2 ndi 2.3, komwe ndiko kachulukidwe kwambiri pakati pa ma crucibles padziko lapansi. Kachulukidwe kake kameneka kamapangitsa kuti crucible mulingo woyenera matenthedwe madutsidwe, bwino kwambiri kuposa mitundu ina ya crucibles.

Glaze ndi kukana dzimbiri
Pamwamba pa chitsulo chosungunula cha aluminium graphite crucible chimakutidwa ndi zigawo zinayi za zokutira zapadera za glaze, zomwe, kuphatikiza ndi zinthu zowuma zowuma, zimathandizira kwambiri kukana kwa dzimbiri kwa crucible ndikuwonjezera moyo wake wautumiki. Mosiyana ndi zimenezi, ziboliboli zapakhomo zimakhala ndi simenti yokhayo yowonjezera pamwamba, yomwe imawonongeka mosavuta ndipo imayambitsa oxidation msanga wa crucible.

Kupanga ndi matenthedwe madutsidwe
Mtsuko wamkuwa wa graphite crucible umagwiritsa ntchito graphite yachilengedwe, yomwe imakhala ndi matenthedwe abwino kwambiri. Mosiyana, zoweta graphite crucibles ntchito kupanga graphite, kuchepetsa graphite okhutira kuchepetsa ndalama, ndi kuwonjezera dongo lalikulu akamaumba, kotero madutsidwe matenthedwe kwambiri yafupika.

Malo opaka ndi kugwiritsa ntchito
Kulongedza
Mtsuko wa graphite wosungunuka wa mkuwa nthawi zambiri umamangidwa m'mitolo ndi kupakidwa ndi zingwe za udzu, yomwe ndi njira yosavuta komanso yothandiza.

Kuwonjezeka kwa magawo ogwiritsira ntchito
Ndi kupita patsogolo kosalekeza kwaukadaulo, magawo ogwiritsira ntchito ma graphite crucibles akupitiliza kukula. Makamaka popanga ma aluminium alloy die castings ndi castings, ma graphite crucibles akusintha pang'onopang'ono miphika yachitsulo kuti ikwaniritse zofunikira zopangira zida zamagalimoto apamwamba kwambiri.

Pomaliza
Kugwiritsa ntchito njira yozizira ya isostatic pressing kwabweretsa magwiridwe antchito komanso magwiridwe antchito a copper-graphite crucible smelting pamlingo wina watsopano. Kaya ndizofanana, mphamvu kapena kutentha kwamkati kwamkati, ndikwabwino kwambiri kuposa njira zachikhalidwe zopangira. Ndi kufalikira kwa ukadaulo wapamwambawu, kufunikira kwa msika kwa ma graphite crucibles kupitilira kukula, ndikuyendetsa bizinesi yonse kukhala tsogolo labwino komanso lokonda zachilengedwe.
