silicon carbide crucibles uye saggers mugadziri
Chigadzirwa chacho chakanakira hovhoni yeindasitiri, sintering, kunyungudika uye inoshanda kune ese marudzi ezvigadzirwa. Mumunda wemakemikari indasitiri, petroleum uye kuchengetedzwa kwezvakatipoteredza nemhando dzakasiyana dzekushandisa.
1) Kugadzikana kwekupisa kwekupisa
2) kemikari isingadziviriri
3) Kushatirwa kwepamusoro-kutsungirira (kusvika 1650 °
4) Kupfeka / ngura / oxidation inopesana
5) Kunyanya kushanda kwesimba remagetsi
6) Kuchenesa kana kuseta iyo yakanyanya kuoma-pasi

Tsanangudzo:
A crucible ipoto ye ceramic inoshandiswa kubata simbi yekunyungudika muchoto. Iyi imhando yepamusoro, giredhi giredhi crucible rinoshandiswa nevekutengesa foundry indasitiri.
Zvazvinoita:
A crucible inodiwa kuti ishingirire tembiricha yakanyanyisa inowanikwa mukunyunguduka kwesimbi. Iyo crucible material inofanirwa kunge iine yakanyanya kunyungudika kupfuura iyo simbi iri kunyungudutswa uye inofanirwa kunge iine simba rakanaka kunyangwe ichipisa chichena.
Zvinogoneka kushandisa imba yakagadzirwa simbi crucible kunyungudutsa simbi senge zingi nealuminium, nekuti simbi idzi dzinonyungudika patembiricha iri pasi peiyo simbi. Nekudaro kuyera (kubhenda) kwesimbi inorovera mukati idambudziko. Ichi chikero chinogona kusvibisa kunyungudika uye kutetepa madziro anorovera pane nekukurumidza. Simbi crucibles inoshanda kana iwe uchangotanga uye usanetseka kubata nekuyera.
Zvakajairika refractory zvinhu zvinoshandiswa pakuvaka crucible ivhu-graphite, uye kabhoni yakasungirirwa silicon-carbide. Izvi zvinhu zvinogona kumira tembiricha yepamusoro mune yakajairwa foundry basa. Silicon carbide ine mukana wakawedzerwa wekuve chinhu chakasimba kwazvo.
Yedu Clay Graphite Bilge Shape crucibles yakatemerwa 2750 °F (1510 °C). Ivo vachabata zinc, aluminium, ndarira / ndarira, sirivheri negoridhe alloys. Mugadziri anoti anogona kushandiswa simbi yakakandwa. Yakagadzirwa muUnited States!
Crucible Shapes:
Bilge shaped ("B" Shape) crucible yakaumbwa sedhiramu rewaini. Iyo "bilge" dimension ndiyo dhayamita yecrucible panzvimbo yayo yakakura. Kana pasina dhayamita yebilge inoratidzwa ipapo dhayamita yepamusoro ndiyo hupamhi hwepamusoro.
Mutemo wechigunwe unotaura kuti # ye "bilge" crucible inopa simba rayo rekushanda mumapaundi ealuminium. Zvendarira kana bhuronzi shandisa katatu crucible #. Semuyenzaniso #10 crucible ingabata makirogiramu gumi ealuminium uye makirogiramu makumi matatu endarira.
Yedu "B" chimiro crucibles anowanzo shandiswa nevanofarira uye vanogaro dhiza. Aya ndiwo emhando yepamusoro, anogara kwenguva refu yekutengesa giredhi crucible.
Tarisa matafura ari pazasi kuti uwane saizi yakakodzera yebasa rako.
Mashandisiro Acho:
Ese macrucibles anofanirwa kubatwa nemabatiro akakodzera (kusimudza chishandiso). Zvibatiso zvisina kufanira zvinogona kukonzera kukuvadzwa kana kutadza zvachose kwe crucible panguva yakaipisisa.
Dhisiki yekadhibhodhi inogona kuiswa pakati peiyo crucible uye chigadziko chechoto isati yapisa. Izvi zvichapisa, zvichisiya musara wekabhoni pakati uye kudzivirira crucible kuti isanamatira kuzasi kwechoto. Kupfeka kwePlumbago (Carbon Black) kunoita zvimwe chetezvo.
Zvakanakisisa kushandisa crucible yakasiyana kune imwe neimwe yemhando yesimbi kudzivirira kusvibiswa. Zvakare iva nechokwadi chekubvisa zvachose crucible mushure mekushandisa. Simbi yakasara kuti isimbise mu crucible inogona kuwedzera pakupisa nekuiparadza.
Ndokumbira udzikise macrucible matsva kana ayo anga ari mudura. Pisai crucible isina chinhu kwemaawa maviri pa220 F (104 C). (Shandisa mhepo yakakwana. Ma crucibles matsva anopfungaira panogadzikwa glaze.) Wobva wapisa crucible isina chinhu kumoto mutsvuku. Bvumira crucible kuti itonhore kusvika kukamuri tembiricha muchoto usati washandisa. Iyi nzira inofanirwa kuteverwa kune ESE macrucibles matsva uye chero crucible angave akaoneswa kune hunyoro mamiriro ekuchengetera.
Chengetedza macrucibles ese munzvimbo yakaoma. Hunyoro hunogona kukonzera crucible kutsemuka pakudziya. Kana yave yakachengetwa kwekanguva zviri nani kudzokorora kushatirwa.
Silicon carbide crucibles ndiyo isingaite mhando yekutora mvura mukuchengetedza uye kazhinji haidi kudzikamiswa isati yashandiswa. Iyo ipfungwa yakanaka kupisa crucible nyowani kune dzvuku kupisa isati yatanga kushandiswa kutyaira nekuomesa fekitori mabhandi nemabhainda.
Izvo zvinhu zvinofanirwa kuiswa mucrucible VERY zvakasununguka. Usambofa "kurongedza" crucible, sezvo zvinhu zvichawedzera pakupisa uye zvinogona kupaza ceramic. Kana chinhu ichi chikanyunguduka mu "chitsitsinho", nyatsoisa zvinhu zvakawanda mumatope ekunyunguduka. (YAMBIRO: Kana chero mwando uripo pachinhu chitsva KUFUDUKA kweutsi kuchaitika). Kamwe zvakare, usanyatsorongedza musimbi. Ramba uchidyisa zvinhu mukunyunguduka kusvikira huwandu hunodiwa hwanyunguduka.
YAMBIRO !!!: Macrucibles ane ngozi. Kunyungudika simbi mucrucible kune ngozi. Kudira simbi muforoma kune njodzi. A crucible anogona kukundikana pasina yambiro. Crucibles inogona kunge iine hurema hwakavanzika mumidziyo uye kugadzira izvo zvinogona kutungamirira mukukundikana, kukuvara kwepfuma, kukuvara kwemunhu, kukuvara kune vanomira uye kurasikirwa kwehupenyu.
Crucible Base Block
Tsanangudzo:
BCS A base block chigadziko chekushisa chepamusoro chinoshandiswa kusimudza crucible kunzvimbo inopisa yevira.
Zvazvinoita:
Chigadziko chinowanzo shandiswa muchoto chakabatidzwa gasi kusimudza crucible kumusoro kuti murazvo wekupisa usaputika zvakananga mumadziro akatetepa ecrucible. Kana murazvo wekupisa ukatenderwa kurova zvakananga crucible inogona kukonzera kukanganisa kwemadziro ecrucible nekudaro kupfupisa hupenyu hwayo. Nzira chaiyo yekudzivirira iyi ndeye kushandisa base block kusimudza crucible kunze kwenzvimbo yekupisa.
Kusimudza crucible kunobvumirawo kuti ive mu "nzvimbo inopisa" yevira. Kunyangwe murazvo wekupisa uchipinda mumuviri wechoto pazasi nzvimbo inopisa kwazvo kubva pakati kusvika kumusoro. Iri munharaunda iyi iyo masvingo echoto anopisa nemhepo inotenderera inobudirira. Kuve nemativi echibhorani munharaunda ino kunokurudzira kupisa kwakanakisa kubva kune mhirizhonga gasi rukova uye nemwaranzi wekupisa wechoto chinopenya madziro emukati.
Mashandisiro Acho:
Chigadziko chinofanirwa kunge chakareba kuti moto unopisa uenderane nepamusoro pechivharo. Zvakanaka kana pamusoro pechivharo chakakwira kupfuura chinopisa chinopisa zvakare. Chausingade kuita kuti murazvo urove mativi matete emuchinjiko. Izvo zvakare zvinogamuchirika kana murazvo ukarova gobvu rezasi chikamu checrucible sezvo ichi chikamu chisinga shandiswe kupfeka kubva kugasi.
Shandong Zhongpeng Special Ceramics Co., Ltd ndeimwe yeyakakura silicon carbide ceramic zvinhu zvitsva zvinogadziriswa muChina. SiC technical ceramic: Kuomarara kweMoh ndeye 9 (Kuoma kweMoh kutsva ndeye 13), nekupokana kwakanyanya kukukurwa nekuora, kunyura kwakanakisa - kuramba uye anti-oxidation.
