Kugwiritsa ntchito ndi kukonza njira ya chowotcha kutentha

1. Kupendekeka kwa ng’anjo: Kufunika kuzindikirika ndi chogwirira pa kontrakitala. Kankhirani chogwirira ntchito cha valavu yobwerera m’njira zambiri kupita ku “mmwamba”, ndipo ng’anjoyo idzawuka, zomwe zimapangitsa kuti zitsulo zamadzimadzi zituluke kuchokera mumphuno ya ng’anjo. Ngati chogwiriracho chikubwezeredwa ku malo apakati “kusiya”, ng’anjoyo idzakhalabe mu chikhalidwe choyambirira, kotero thupi la ng’anjo likhoza kukhala pamalo aliwonse pakati pa 0-95 °. Kanikizani chogwiriracho ku malo “pansi”, ndipo thupi la ng’anjo likhoza kuchepetsedwa pang’onopang’ono.

2. Chida chopangira ng’anjo ya ng’anjo: Yendetsani thupi la ng’anjo ku 90 °, gwirizanitsani silinda ya ejector ndi m’munsi mwa thupi la ng’anjo, gwirizanitsani payipi yothamanga kwambiri ndikusintha liwiro la silinda ya ejector. Kanikizani chogwirizira cha “ng’anjo ya ng’anjo” pa kontrakitala mpaka “mu” malo kuti mutulutse ng’anjo yakale. Kokani chogwirira ku “kumbuyo” malo, chotsani pambuyo poti silinda yabwezeretsedwa, bwererani thupi la ng’anjo mutatha kuyeretsa ng’anjoyo, fufuzani matope a refractory ndikukweza gawo la ejector kuti muyambe kulumikiza ng’anjo yatsopano.

3. Pamene ng’anjo yosungunula induction ikugwira ntchito, payenera kukhala madzi ozizira okwanira mu inductor. Nthawi zonse fufuzani ngati kutentha kwa madzi kwa chitoliro chilichonse kuli bwino.

4. Chitoliro cha madzi ozizira chiyenera kutsukidwa ndi mpweya woponderezedwa nthawi zonse, ndipo chitoliro cha mpweya woponderezedwa chikhoza kulumikizidwa ndi mgwirizano pa chitoliro cholowetsa madzi. Zimitsani gwero la madzi musanadule polumikizira chitoliro.

5. Pamene ng’anjo imatsekedwa m’nyengo yozizira, ziyenera kuzindikiridwa kuti sipayenera kukhala madzi otsalira mu coil induction, ndipo ayenera kuwombedwa ndi mpweya woponderezedwa kuti ateteze kuwonongeka kwa inductor.

6. Poika busbar ya ng’anjo yosungunula induction, ma bolt ophatikizana ayenera kumangirizidwa, ndipo ng’anjo ikatsegulidwa, ma bolts ayenera kufufuzidwa pafupipafupi kuti azitha kumasuka.

7. Pambuyo poyatsa ng’anjo yosungunuka yotsekemera, yang’anani ngati zolumikizira ndi zomangirira zili zotayirira, ndipo samalani kwambiri ndi ma bolts omwe amalumikiza mbale zoyendetsera.

8. Pofuna kupewa ngozi zomwe zimayambitsidwa ndi ng’anjo pansi pa ng’anjo, chipangizo chodzidzimutsa cha ng’anjo chimayikidwa pansi pa ng’anjo. Chitsulo chamadzimadzi chikatuluka, chidzalumikizidwa ndi electrode yapansi ya chitsulo chosapanga dzimbiri pansi pa ng’anjo ndipo chipangizo cha alamu chidzatsegulidwa.

9. Pamene khoma la crucible lawonongeka, liyenera kukonzedwa. Kukonza kumagawidwa pawiri: kukonza kwathunthu ndi kukonza pang’ono.

9.1. Kukonzanso kwathunthu kwa ng’anjo yosungunula induction:

Amagwiritsidwa ntchito ngati khoma la crucible likukokoloka mofanana mpaka makulidwe a 70mm.

Masitepe okonza ndi awa;

9.2. Chotsani slag yonse yomwe imayikidwa pa crucible mpaka cholimba choyera chitayike.

9.3. Ikani nkhungu ya crucible yomwe imagwiritsidwa ntchito pomanga ng’anjo, pakati ndikuikonza m’mphepete mwapamwamba.

9.4. Konzani mchenga wa quartz molingana ndi chilinganizo ndi njira yogwiritsira ntchito zomwe zaperekedwa mu 5.3, 5.4, ndi 5.5.

9.5. Thirani mchenga wa quartz wokonzedwa pakati pa crucible ndi crucible mold, ndipo gwiritsani ntchito φ6 kapena φ8 mipiringidzo yozungulira kuti mumange.

9.6. Pambuyo pophatikizana, onjezerani chowotcha mu crucible ndikutenthetsa mpaka 1000 ° C. Ndi bwino kusunga kwa maola atatu musanapitirize kukweza kutentha kuti musungunuke.

9.7, kukonza pang’ono:

Amagwiritsidwa ntchito ngati makulidwe a khoma lapafupi ndi osakwana 70mm kapena kukokoloka ndi kusweka pamwamba pa koyilo yolowera.

Masitepe okonza ndi awa:

9.8. Chotsani slag ndi sediment pamalo owonongeka.

9.10, Konzani mtengowo ndi mbale yachitsulo, lembani mchenga wa quartz wokonzedwa, ndikuwongolera. Samalani kuti musalole kuti mbale yachitsulo isunthe pamene mukugunda.

Ngati gawo la dzimbiri ndi losweka lili mkati mwa koyilo yolowera, njira yokonzanso yokwanira ikufunikabe.

9.11, Patsani mafuta mbali zokometsera za ng’anjo yolowera nthawi zonse.

9.12. Ma hydraulic system amatenga 20-30cst (50 ℃) hydraulic mafuta, omwe amayenera kukhala aukhondo ndikusinthidwa pafupipafupi.

9.13. Panthawi yosungunula, chidwi chiyenera kuperekedwa ku zizindikiro za zida ndi zolemba za chipangizo cha alamu chotuluka.
