Chii chinonzi graphite electrodes inoshandiswa?

Graphite electrodes anoshandiswa zvakanyanya mu Electric Arc Furnace kana Ladle Furnace simbi kugadzira.

Graphite electrodes inogona kupa yakakwira mazinga emagetsi conductivity uye kugona kuchengetedza yakanyanyisa mazinga ekupisa anogadzirwa. Graphite electrodes inoshandiswawo mukunatsa simbi uye zvakafanana smelting maitiro.

1. Chigadziro che electrode chinofanira kubatwa panzvimbo inodarika mutsara wekuchengetedza we electrode yepamusoro; kana zvisina kudaro electrode yaizoputsika nyore nyore. Nzvimbo yekubatana pakati pemubati uye electrode inofanira kucheneswa nguva dzose kuchengetedza kubata kwakanaka. Iyo bhachi inotonhorera yemubati ichadzivirirwa kubva pakudonha kwemvura.
2. Ziva zvikonzero kana pane gaka mumagetsi e electrode, usashandise muntil gap rabviswa.
3. Kana pane kudonha kwe nipple bolt paunenge uchibatanidza ma electrodes, zvakakosha kupedzisa nipple bolt.
4. Kushandiswa kwe electrode kunofanira kudzivisa kushanda kwetilting, kunyanya, boka rema electrode akabatanidzwa harifaniri kuiswa nehova kuitira kudzivirira kubva pakuputsika.
5. Paunenge uchitengesa zvinhu kuchoto, zvinhu zvakawanda zvinofanira kubhadharwa kunzvimbo yepasi rechoto, kuitira kuti kuderedza kukanganiswa kwezvinhu zvakakura zvevira pane electrodes.
6. Zvikamu zvakakura zvekudzivirira zvinhu zvinofanira kudziviswa kusungirirwa pasi pemagetsi kana kunyunguduka, kuitira kudzivirira kubva pakukanganisa kushandiswa kwe electrode, kana kunyange kuputsika.
7. Dzivisa kudonha chivharo chevira paunenge uchikwira kana kudonha ma electrodes, izvo zvinogona kukonzera kukanganisa kwe electrode.
8. Izvo zvinodikanwa kudzivirira simbi slag kubva pakuputika kusvika kune tambo dze electrodes kana nipple yakachengetwa munzvimbo yekunyungudutsa, iyo yangu inokuvadza kurongeka kwetambo.

► Chikonzero chekuputsika kweElectrode

1. Electrode stress status kubva pasi pasi pasi pahurongwa hwekudzikira; majoini emagetsi nema nipples pasi pe clamping mudziyo anotora simba guru.
2. Apo electrodes inogamuchira simba rekunze; Stress concentration yesimba rekunze yakakura kupfuura iyo electrode inogona kumira ipapo simba rinotungamira kuputsika kwe electrode.
3. Zvikonzero zvesimba rekunze ndezvi: kunyunguduka kwehuwandu hwekuchaja kudonha; zvimedu zvisiri-conductive zvinhu pazasi pe electrode: kukanganisa kwesimbi yakakura kuyerera uye nezvimwe. Electrodes gap rakabatana nekubatana kwakashata uye simba remuzamu harina kuenderana.
4. Electrodes nema nipples ane hurombo machining accuracy.

► Chengetedzo yekushandisa iyo graphite electrode:

1. Wet graphite electrodes inofanira kuomeswa isati yashandiswa.
2. Mafuro ekudzivirira evhavha pamagetsi e electrode achabviswa kuti aone kuvimbika kwetambo dzemukati dze electrode socket.
3. Nzvimbo dzema electrodes uye tambo dzomukati dzesokisi dzichacheneswa nemhepo yakamanikidzwa isina mafuta nemvura. Hapana jira resimbi kana jecha resimbi richashandiswa pakuchenesa kwakadaro.
4. Zamu rinofanirwa kukwizwa zvine mutsindo musocket ye electrode yeimwe mugumo we electrode pasina kubonderana neshinda dzemukati t haina kukurudzirwa kuisa zvakananga zamu mu electrode yakabviswa muchoto)
5. Chishandiso chekusimudza (chinosarudzwa kutora mudziyo wekusimudza graphite) chinofanirwa kukandwa musoketi ye electrode yeimwe magumo e electrode.
6. Paunenge uchisimudza electrode, cushion-like zvinhu zvinofanira kuiswa pasi pasi pekupedzisira kwekubatanidza kwe electrode kuti usapinda chero kupi zvako. Mushure mekunge hoki yekusimudza yaiswa mumhete yemudziyo wekusimudza. Iyo electrode ichasimudzwa zvakanaka kudzivirira kuti irege kudonha kana kubonderana nechero imwe gadziriso.
7. Iyo electrode ichasimudzwa pamusoro pemusoro we electrode inoshanda uye inodonha zvishoma nezvishoma inotarisa pane electrode socket. Ipapo iyo electrode ichakwizwa kuita helical hoko uye electrode kuderera uye kugadzirisa pamwechete. Kana chinhambwe chiri pakati pezviso zvekupedzisira zvema electrode maviri chiri 10-20mm, mativi maviri emagumo emagetsi uye chikamu chekunze chezamu chinofanira kucheneswa zvakare nemhepo yakamanikidzwa. Pakupedzisira electrode inofanira kuiswa zvinyoro-nyoro, kana kuti tambo dze electrode socket uye nipple ichakuvadzwa nekuda kwekurovera kwechisimba.
8. Shandisa torque spanner kupeta electrode kusvika panoperera zviso zvema electrode maviri anyatsobatana (mukana wekubatana chaiko pakati pema electrode hausi pasi pe0.05mm).
Kuti uwane rumwe ruzivo nezve mashandisirwo emagetsi egraphite, tichengetedze tiine ruzivo chero nguva.
