Sei ma graphite crucibles achitsemuka? Nzira yekuigadzirisa sei?

Inotevera ongororo yakadzama yezvikonzero zvekutsemuka:
1. Mushure mokunge crucible ichishandiswa kwenguva yakareba, rusvingo rwechifukidzo runopa kuputika kwenguva refu, uye rusvingo rwakaputika pakuputika rwakaonda.
(chikonzero chekuongorora: crucible yave kuda kana kuti yasvika pahupenyu hwayo hwesevhisi, uye iyocruciblemadziro anozotetepa uye haakwanise kutakura simba rekunze rakawandisa.)
2. Iyo crucible yakashandiswa kwekutanga (kana kuswedera kune itsva) inoratidza kuputika pamwe chete uye inomhanya nepakati pezasi.
(cause analysis: isa crucible yakatonhorera mu ahigh-tembirichamoto unopisa, kana kupisa pasi pechibhorani nekukurumidza kana crucible iri mumamiriro ekutonhora. Kazhinji, kukuvara kuchaperekedzwa nekupenya kwe glaze.)
3. Longitudinal crack inowedzera kubva kumucheto wepamusoro wecrucible.
(chikonzero chekuongorora: inoumbwa nekupisa crucible nekukurumidza, kunyanya kana kupisa kwekupisa kuzasi uye kumucheto kwezasi kwe crucible kunokurumidza kupfuura iyo iri kumusoro. Kushanda kwemuchato kumucheto wepamusoro we crucible zvakare nyore. kukonzeresa kukuvara. Iyo isina kukodzera crucible kana kugogodza pamupendero wepamusoro kuchakonzerawo kukuvadza kwakaoma uye kukuvadza kuri pachena pamucheto wepamusoro wecrucible.)
4. Longitudinal crack padivi re crucible (kutsemuka hakupfuuri kumusoro kana pasi pe crucible).
(chikonzero chekuongorora: inowanzoumbwa nekumanikidzwa mukati. Semuenzaniso, kana iyo yakatonhodzwa wedge-shaped cast material yakaiswa nechemberi mucrucible, wedge-shaped cast material inozokuvadzwa mushure.kuwedzera kwekushisa.)
2, Transverse crack yegraphite crucible:
1. Pedyo nepasi pe crucible (zvinogona kukonzera pasi pe crucible kudonha)(cause analysis: inogona kukonzerwa nekukanganisa kwezvinhu zvakaoma, sekukanda zvinhu zvekukanda mucrucible, kana kugogodza pasi nezvinhu zvakaoma seiron bar. Rudzi urwu rwekukuvara ruchakonzerwawo nekuwedzera kukuru kwemafuta mune imwe 1b).
2. Inenge hafu yekutarisa kwe crucible.
(chikonzero chekuongorora: chikonzero chinogona kunge chiri chekuti crucible inoiswa pane slag kana kuti isina kukodzera crucible base. Paunenge uchibvisa crucible, kana crucible clamping position iri pedyo zvakanyanya nepamusoro uye simba rakanyanyisa, kuputika kuchaonekwa pa pamusoro pe crucible pazasi chikamu checrucible clamp)
3. Apo SA series crucibles inoshandiswa, pane kuputika kwepamusoro kune chikamu chezasi checrucible nozzle.
(chikonzero chekuongorora: iyo crucible haina kuisirwa nenzira kwayo. Pakuisa crucible nyowani, kana ivhu refractory rakatsikirirwa pasi pe crucible nozzle, iyo stress pfungwa dzinosangana pa crucible nozzle panguva yekutonhora uye kupfupisa kwe crucible panguva yekushanda, zvichikonzera. mumakorokoza).
