Izinyathelo zokuqapha ukusetshenziswa kwe-graphite electrode.

I-graphite iyinhlanganisela eyakhiwe ngama-elementi e-carbon. Isakhiwo sayo se-athomu sihlelwe ngephethini yezinyosi ezinezinhlangothi ezine. Ama-electron amathathu kwamane angaphandle kwe-nucleus ye-athomu enza amabhondi aqinile futhi azinzile ane-covalent nama-electron enuclei ye-athomu eseduze, futhi i-athomu eyengeziwe ingahamba ngokukhululeka eduze kwendiza yenethiwekhi, iyinikeze indawo yokuguquguquka kukagesi.

Izinyathelo zokuqapha ukusetshenziswa kwe-graphite electrode

1. Ukuvikela umswakama - Gwema imvula, amanzi noma umswakama. Yomisa ngaphambi kokusetshenziswa.

2. Ukuvimbela ukushayisana - Bamba ngokucophelela ukuze uvimbele ukulimala nokushayisana ngesikhathi sokuthutha.

3. Ukuvimbela ukuqhekeka - Uma uhlanganisa i-electrode ngama-bolts, qaphela amandla asetshenziselwa ukuvimbela ukuqhekeka ngenxa yokuphoqa.

4. I-Anti-breakage - I-graphite i-brittle, ikakhulukazi kuma-electrode amancane, amancane futhi amade, ajwayele ukuphuka ngaphansi kwamandla angaphandle.

5. Ingangenwa uthuli - Amathuluzi angangeni uthuli kufanele afakwe ngesikhathi sokucutshungulwa ngomshini ukuze kuncishiswe umthelela empilweni yomuntu kanye nemvelo.

6. Ukuvimbela intuthu - Imishini yokukhipha ugesi ijwayele ukukhiqiza intuthu enkulu, ngakho-ke imishini yokukhipha umoya iyadingeka.

7. Ukuvimbela i-carbon deposition - I-graphite ijwayele ukuchithwa kwe-carbon ngesikhathi sokukhishwa. Ngesikhathi sokucubungula ukukhishwa, kuyadingeka ukuqapha ngokucophelela isimo sayo sokucubungula

Ukuqhathaniswa Kwemishini Yokukhipha Ugesi Ye-Graphite Ne-Red Copper Electrodes (Kudingeka ubuhlakani obuphelele)

1. Ukusebenza okuhle kokucubungula kwemishini: Ukumelana nokusika kungu-1/4 wethusi, futhi ukusebenza kahle kokucubungula kuyizikhathi ezi-2 kuya kwezi-3 kunezethusi.

2. I-electrode kulula ukuyipholisha: Ukwelashwa okungaphezulu kulula futhi akunawo ama-burrs: Kulula ukusikwa ngesandla. Ukwelashwa kwe-surface elula nge-sandpaper kwanele, okugwema kakhulu ukuhlanekezela komumo okubangelwa amandla angaphandle ekubunjweni nobukhulu be-electrode.

3. Ukusetshenziswa kwe-electrode okuphansi: Inokusebenza kahle kukagesi kanye nokumelana okuphansi, okuyi-1/3 kuya ku-1/5 yaleyo yethusi. Ngesikhathi sokusebenza kanzima, ingakwazi ukufeza ukukhishwa okungalahleki.

4. Isivinini sokukhipha ngokushesha: Ijubane lokukhipha liphindwe izikhathi ezingu-2 kuya kwezi-3 kunethusi. Igebe emishinini enzima lingafinyelela ku-0.5 kuya ku-0.8 mm, kanti elamanje lingaba likhulu njengo-240A. Ukugqoka kwe-electrode kuncane uma kusetshenziswe ngokujwayelekile iminyaka eyi-10 kuye kwengama-120.

5. Isisindo esilula: Nge-gravity ethize ye-1.7 kuya ku-1.9, eyi-1/5 yaleyo yethusi, inganciphisa kakhulu isisindo sama-electrode amakhulu, yehlise umthwalo kumathuluzi omshini kanye nobunzima bokufakwa ngesandla nokulungiswa.

6. Ukumelana nezinga lokushisa eliphezulu: Izinga lokushisa le-sublimation lingu-3650 ℃. Ngaphansi kwezimo zokushisa okuphezulu, i-electrode ayithambisi, igwema inkinga yokuguquguquka kwezinto zokusebenza ezinezindonga ezincane.

7. Ukuguqulwa kwama-electrode amancane: I-coefficient yokunwetshwa kwe-thermal ingaphansi kuka-6 ctex10-6 /℃, okuyi-1/4 kuphela yaleyo yethusi, ithuthukisa ukunemba kwe-dimensional kokukhipha.

8. Imiklamo ehlukene ye-electrode: Ama-electrode e-graphite kulula ukuhlanza amakhona. Ama-workpieces ngokuvamile adinga ama-electrode amaningi angaklanywa abe yi-electrode eyodwa ephelele, athuthukise ukunemba kwesikhunta futhi anciphise isikhathi sokukhipha.

A.Ijubane lomshini wegraphite lishesha ukwedlula elethusi. Ngaphansi kwezimo ezifanele zokusetshenziswa, ishesha izikhathi ezi-2 kuya kwezi-5 kunethusi.

B. Asikho isidingo sokusebenzisa inani elikhulu lamahora okusebenza ukuze ukhokhe njengethusi;

C. I-Graphite inezinga lokukhipha ngokushesha, eliphindwe izikhathi ezingu-1.5 kuya kwezingu-3 kunethusi ekucubungulweni kukagesi

D. Ama-electrode e-graphite anokuguga okuphansi, okunganciphisa ukusetshenziswa kwama-electrode

E. Intengo izinzile futhi ayithinteki kangako ukushintsha kwentengo yemakethe

F. Ingakwazi ukumelana namazinga okushisa aphezulu futhi ihlale ingaguquki ngesikhathi somshini wokukhipha ugesi

G. Ine-coefficient encane yokwandisa okushisayo nokunemba kwesikhunta esiphezulu

H. Isisindo esincane, singahlangabezana nezidingo zesikhunta esikhulu nesiyinkimbinkimbi

Ingaphezulu kulula ukulicubungula futhi kulula ukuthola indawo efanelekile yokucubungula
