Kodi ma electrode a graphite amagwiritsidwa ntchito pa chiyani?

Ma electrode a grafiti amagwiritsidwa ntchito makamaka popanga zitsulo za Electric Arc Furnace kapena Ladle Furnace.

Ma electrode a grafiti amatha kupereka mphamvu zamagetsi zambiri komanso kuthekera kosunga kutentha kwakukulu komwe kumapangidwa. Ma electrode a grafiti amagwiritsidwanso ntchito pokonzanso chitsulo ndi njira zina zoyeretsera.

1. Chogwirira ma electrode chiyenera kusungidwa pamalo opitilira mzere wachitetezo wa electrode yapamwamba; apo ayi electrode ingasweke mosavuta. Malo olumikizirana pakati pa chogwirira ndi electrode ayenera kutsukidwa nthawi zonse kuti agwirizane bwino. Jekete loziziritsira la chogwiriracho liyenera kupewedwa kuti madzi asatuluke.
2. Dziwani zifukwa ngati pali mpata mu malo olumikizirana ma electrode, musagwiritse ntchito mpaka mpata utachotsedwa.
3. Ngati boluti ya nipple ikugwa polumikiza ma electrode, ndikofunikira kumaliza boluti ya nipple.
4. Kugwiritsa ntchito ma electrode kuyenera kupewa kupendekeka, makamaka, gulu la ma electrode olumikizidwa siliyenera kuyikidwa mopingasa kuti lisasweke.
5. Mukayika zinthu mu ng'anjo, zinthu zambiri ziyenera kuyikidwa pansi pa ng'anjo, kuti zichepetse mphamvu ya zinthu zazikulu za ng'anjo pa ma electrode.
6. Zidutswa zazikulu za zinthu zotetezera kutentha ziyenera kupewedwa kuti zisaikidwe pansi pa ma electrode akamasungunuka, kuti zisakhudze kugwiritsa ntchito ma electrode, kapena kusweka.
7. Pewani kugwetsa chivindikiro cha ng'anjo mukakweza kapena kugwetsa ma electrode, zomwe zingawononge ma electrode.
8. Ndikofunikira kupewa kuti chitsulo chisalowe mu ulusi wa ma electrode kapena nipple yomwe imasungidwa pamalo osungunula, zomwe zingawononge kulondola kwa ulusiwo.

► Chifukwa Cha Kusweka kwa Ma Electrode

1. Kupsinjika kwa ma elekitirodi kuchokera ku mphamvu yotsika pang'onopang'ono; cholumikizira cha ma elekitirodi ndi ma nipples pansi pa chipangizo cholumikizira chimatenga mphamvu yayikulu.
2. Pamene ma electrode alandira mphamvu yakunja; Kuchuluka kwa mphamvu yakunja kumakhala kwakukulu kuposa momwe electrode ingapiririre, ndiye kuti mphamvuyo idzapangitsa kuti electrode isweke.
3. Zomwe zimayambitsa mphamvu yakunja ndi izi: kusungunuka kwa kugwa kwa mphamvu yamagetsi; zinthu zosagwira ntchito pansi pa elekitirodi: kukhudzidwa kwa kuyenda kwamphamvu kwachitsulo ndi zina zotero. Kuthamanga kwa yankho la chipangizo chomangirira chokweza chosagwirizana: elekitirodi ya chivindikiro cha dzenje laling'ono; kusiyana kwa ma elekitirodi komwe kumalumikizidwa ndi kulumikizana koyipa komanso mphamvu ya nipple sikukwaniritsa zomwe ikufuna.
4. Ma electrode ndi ma nipples omwe ali ndi luso lochepa lokonza zinthu.

► Chenjezo pakugwiritsa ntchito graphite electrode:

1. Ma electrode a graphite onyowa ayenera kuumitsidwa musanagwiritse ntchito.
2. Zipewa zoteteza thovu zomwe zili pa soketi ya ma electrode ziyenera kuchotsedwa kuti zitsimikizire kuti ulusi wamkati mwa soketi ya ma electrode ndi wolondola.
3. Pamwamba pa ma electrode ndi ulusi wamkati wa soketi ziyenera kutsukidwa ndi mpweya wopanikizika popanda mafuta ndi madzi. Ubweya wachitsulo kapena nsalu yachitsulo ya mchenga siyenera kugwiritsidwa ntchito pamalo otere.
4. Nipple iyenera kukulungidwa mosamala mu soketi ya electrode ya mbali imodzi ya electrode popanda kugundana ndi ulusi wamkati. Sikoyenera kuyika nipple mwachindunji mu electrode yochotsedwa mu uvuni.
5. Chipangizo chonyamulira (chimakonda kugwiritsa ntchito chipangizo chonyamulira cha graphite) chiyenera kukulungidwa mu soketi ya electrode kumapeto ena a electrode.
6. Mukakweza electrode, zinthu zofanana ndi khushoni ziyenera kuyikidwa pansi pansi pa mapeto olumikizira a electrode kuti zisagunde. Pambuyo poti chokweza chayikidwa mu mphete ya chipangizo chokweza, electrode iyenera kunyamulidwa bwino kuti isagwe kapena kugundana ndi china chilichonse.
7. Electrode iyenera kukwezedwa pamwamba pa mutu wa electrode yogwira ntchito ndikugwetsedwa pang'onopang'ono ikuyang'ana pa soketi ya electrode. Kenako electrode idzakulungidwa kuti mbedza yozungulira ndi electrode zichepetse ndikulumikizana. Pamene mtunda pakati pa nkhope za ma electrode awiri uli 10-20mm, nkhope ziwiri za ma electrode ndi gawo lakunja la nipple ziyenera kuchotsedwanso ndi mpweya wopanikizika. Pomaliza electrode iyenera kuyikidwa mofatsa, apo ayi ulusi wa soketi ya electrode ndi nipple zidzawonongeka chifukwa cha kugundana kwamphamvu.
8. Gwiritsani ntchito torque spana kuti mukulungire electrode mpaka mapeto a ma electrode awiriwa agwirizane kwambiri (mpata wa kulumikizana kolondola pakati pa ma electrode ndi wochepera 0.05mm).
Kuti mudziwe zambiri zokhudza kugwiritsa ntchito ma electrode a graphite, chonde tidziwitseni nthawi iliyonse.
