graphite crucibleSilicon carbide graphite cruciblendi chidebe chopangidwa ndi graphite ngati zopangira, kotero chimakhala ndi kukana kwambiri kutentha kwambiri ndipo chingagwiritsidwe ntchito posungunula zitsulo zamafakitale kapena kuponyera.Mwachitsanzo, m'moyo watsiku ndi tsiku, mumatha kumvetsetsa kuti nthawi zambiri pamakhala amalonda kumidzi omwe amakonza miphika ya aluminiyamu kapena miphika ya aluminiyamu.Zida zomwe amagwiritsa ntchito ndi crucibles.Mapepala a aluminiyumu amayikidwa mu crucible ndi kutenthedwa ndi moto mpaka atasungunuka m'madzi a aluminiyamu, Thiraninso ku ming'alu ya mphika, muziziziritsa, ndiyeno zingagwiritsidwe ntchito.Komabe, ma graphite crucibles ndi silicon carbide crucibles amagwiritsidwa ntchito m'makampani.Pakati pawo, ma graphite crucibles amakhala ndi matenthedwe abwino, koma amatha kutulutsa okosijeni ndipo amakhala ndi chiwopsezo chachikulu.Ma silicon carbide graphite crucibles ali ndi voliyumu yayikulu komanso moyo wautali wautumiki kuposa ma graphite crucibles.Takhala tikuchita malonda ndi kupanga crucibles kwa zaka 40.Ma graphite crucibles omwe timapanga ndi oyenera kusungunula golide, siliva, mkuwa, chitsulo, aluminiyamu, nthaka, ndi malata, komanso njira zosiyanasiyana zosungunulira ndi kutentha monga coke, ng'anjo yamafuta, gasi, ng'anjo yamagetsi, ndi zina zambiri. ma graphite crucibles omwe timapanga amayamikiridwa kwambiri ndi makasitomala atsopano ndi akale chifukwa cha khalidwe lawo labwino komanso ntchito yokhazikika.Timayambitsanso ukadaulo wapamwamba wopangira ma crucible - isostatic pressure crucible form form - kutengera msika ndi zosowa zamakasitomala, Ndipo njira yoyeserera yotsimikizika yotsimikizika, silicon carbide crucible yopangidwa ndiukadauloyi ili ndi mawonekedwe a kuchuluka kwa voliyumu, kukana kutentha kwambiri, kuthamanga kwambiri. matenthedwe madutsidwe, asidi ndi alkali dzimbiri kukana, mkulu kutentha mphamvu, ndi mkulu makutidwe ndi okosijeni kukana.Moyo wake wautumiki ndi nthawi 3-5 kuposa ma graphite crucibles.Panthawi imodzimodziyo, imapulumutsa mafuta komanso imachepetsa mphamvu ya ogwira ntchito.Mtengo wamagetsi opulumutsa mphamvu a isostatic pressure crucibles ndi ma isostatic pressure crucibles opulumutsa mphamvu amapangitsa kuti mankhwalawa agwiritsidwe ntchito kwambiri pakusungunula zitsulo zopanda chitsulo.
graphite crucibles angagwiritsidwe ntchito ng'anjo zosiyanasiyana, monga ng'anjo magetsi, sing'anga ng'anjo pafupipafupi, ng'anjo mpweya, kilns, etc., posungunula golide, siliva, mkuwa, chitsulo, aluminiyamu, nthaka, malata, ndi aloyi.Njira yolondola yoyikapo ma graphite crucible ndi silicon carbide crucible
1. Maziko a graphite crucible ayenera kukhala ndi mainchesi ofanana kapena okulirapo ngati pansi pa crucible, ndipo kutalika kwa nsanja ya crucible kuyenera kukhala kopitilira muyeso kuti moto usapondereze pa crucible.
2. Mukamagwiritsa ntchito njerwa zowonongeka monga matebulo opangira, njerwa zozungulira zozungulira ziyenera kugwiritsidwa ntchito, zomwe zimakhala zophwanyika komanso zosapindika.Osagwiritsa ntchito njerwa za theka kapena zosagwirizana.Ndi bwino kugwiritsa ntchito graphite crucible matebulo kunja.
3. Tebulo la crucible liyenera kuikidwa pakatikati pa kusungunuka ndi kusungunuka, ndi ufa wa coke, phulusa la udzu, kapena thonje lokanira ngati pad kuti asagwirizane pakati pa crucible ndi tebulo la crucible.Pambuyo poyika crucible, iyenera kukhala yofanana.
4. Kukula pakati pa crucible ndi thupi la ng'anjo kuyenera kufanana, ndipo mtunda pakati pa crucible ndi khoma losungunuka liyenera kukhala loyenera, osachepera 40mm kapena kuposa.
Mukakweza crucible yokhala ndi milomo mu ng'anjo, kusiyana kwa pafupifupi 30-50MM kuyenera kusungidwa pakati pa pansi pa phula la crucible ndi njerwa yowumitsa, ndipo palibe chomwe chiyenera kuyikidwa pansi.Khoma la mphuno ndi ng'anjo liyenera kusinthidwa ndi thonje la refractory.Khoma la ng'anjo liyenera kukhala ndi njerwa zosasunthika ndipo crucible iyenera kupakidwa ndi makatoni a malata okhala ndi makulidwe pafupifupi 3mm ngati malo okulirapo matenthedwe akatenthedwa.
Ukadaulo wopanga ma graphite crucibles umawonekera makamaka pazinthu monga chilinganizo, zida zopangira, zida zopangira, ndiukadaulo.Pankhani ya kusankha zopangira, ife makamaka ntchito dongo refractory, aggregates, masoka graphite, etc. Malinga ndi ntchito zosiyanasiyana za crucible aliyense, zosakaniza ndi mafomu amene timasankha ndi osiyana, makamaka zimaonekera mu magawo osiyanasiyana a zipangizo zosiyanasiyana.Njirayi ndi kudzera mukumangirira, kuumba mozungulira, ndi kuumba pamanja, komwe ndi kuumba kwa graphite.Pambuyo kupanga akamaumba, nkofunika kukumbukira kuumitsa.Pambuyo poyang'anitsitsa, imakhala yoyenerera, ndipo zinthu zoyenerera zimatha kutsukidwa
