Chifukwa chiyani ma graphite crucibles amasweka? Kodi kuthetsa izo?

Zotsatirazi ndikuwunika mwatsatanetsatane zomwe zimayambitsa ming'alu:
1. Pambuyo pogwiritsira ntchito crucible kwa nthawi yayitali, khoma la crucible limapereka ming'alu yautali, ndipo khoma la crucible pa ming'alu ndilochepa.
(kusanthula chifukwa: crucible yatsala pang'ono kufika kapena yafika pa moyo wake wautumiki, ndicruciblekhoma lidzakhala lochepa thupi ndipo silingathe kupirira mphamvu zambiri zakunja.)
2. Mtsuko womwe umagwiritsidwa ntchito koyamba (kapena pafupi ndi watsopano) umasonyeza ming'alu motsatira ndikudutsa pansi pa crucible.
(cause analysis: ikani crucible yoziziritsidwa mu akutentha kwambirimoto wotentha, kapena tenthetsani pansi pa crucible mofulumira kwambiri pamene crucible ili m'nyengo yozizira. Kawirikawiri, kuwonongeka kudzatsagana ndi glaze peeling.)
3. Mng'alu wautali wotalika kuchokera m'mphepete mwa crucible.
(chifukwa kusanthula: amapangidwa ndi Kuwotcha crucible mofulumira kwambiri, makamaka pamene Kutentha liwiro pansi ndi m'munsi m'mphepete mwa crucible ndi mofulumira kwambiri kuposa pamwamba. Ntchito yokwatiwa pamphepete pamwamba pa crucible imakhalanso yosavuta. kuti awononge zowonongeka.
4. Kuphulika kwautali kumbali ya crucible (kung'amba sikupitirira pamwamba kapena pansi pa crucible).
(kusanthula chifukwa: nthawi zambiri amapangidwa ndikupanikizika kwamkati. Mwachitsanzo, zinthu zotayidwa zokhala ngati mphero zikayikidwa pambali mu crucible, zotayira zokhala ngati mphero zimawonongeka pambuyo pake.kukulitsa kutentha.)
2, Mng'alu wodutsa wa graphite crucible:
1. Pafupi ndi pansi pa crucible (zingayambitse pansi pa crucible kugwa)(kusanthula chifukwa: zitha kuchitika chifukwa cha kukhudzidwa kwazinthu zolimba, monga kuponya zinthuzo mu crucible, kapena kugwetsa pansi ndi zinthu zolimba mongachitsulo chachitsulo. Kuwonongeka kotereku kudzabweranso chifukwa chakukula kwakukulu kwamafuta ena 1b).
2. Pafupifupi theka la kulunjika kwa crucible.
(kufufuza chifukwa: chifukwa chake chikhoza kukhala kuti crucible imayikidwa pa slag kapena maziko osayenera a crucible. Potulutsa crucible, ngati crucible clamping position ili pafupi kwambiri ndi pamwamba ndipo mphamvu ndi yaikulu kwambiri, ming'alu idzawonekera pa pamwamba pa crucible pa m'munsi mwacrucible clamp)
3. Pamene SA mndandanda crucibles ntchito, pali ming'alu yopingasa pa m'munsi mwanozzle crucible.
(kusanthula chifukwa: crucible sichinakhazikitsidwe moyenera. Mukayika crucible yatsopano, ngati dothi losasunthika likakanizidwa mwamphamvu pansi pa mphuno ya crucible, mfundo zopanikizika zimasinthika pamphuno ya crucible panthawi yozizira ndi kufupikitsa crucible panthawi ya ntchito, zomwe zimabweretsa. mu ming'alu).
