Maintenance Technology ya Induction Furnace Wall Lining

1. Pachiyambi choyamba chogwiritsira ntchito crucible, sintered wosanjikiza ndi woonda, ndipo kufalikira kwamphamvu kwambiri kuyenera kupewedwa momwe zingathere, zomwe zidzachititsa kuti maginito amphamvu kwambiri agwedezeke ndikuwononga ng’anjo yamoto.

2. Podyetsa, yesetsani kupewa kuphwanya crucible ndi zipangizo, zomwe zingawononge crucible. Makamaka pambuyo pa ng’anjo yozizira, mphamvu ya crucible imakhala yochepa kwambiri, ndipo chisamaliro chapadera chiyenera kutengedwa kuti ming’alu isawonjezeke, zomwe zingapangitse mwayi wolowera zitsulo zosungunuka ndikuyambitsa ngozi zowonongeka kwa ng’anjo.

3. Pambuyo pa kutentha kwa ng’anjo kumalizidwa, ogwira ntchito amayenera kukhala ndi malingaliro amphamvu a udindo ndipo nthawi zonse amamvetsera kuyang’ana momwe ntchito ya ng’anjo ikugwirira ntchito kuti asunge dongosolo lonse labwino.

4. Pambuyo pa ng’anjo yopangira ng’anjo ikatha, ziribe kanthu chifukwa chake, njira yamadzi ozizira iyenera kuonetsetsa kuti ikuzungulira kwa maola pafupifupi 12, ndipo kutentha kwa chipinda cha ng’anjo kuyenera kukhala kosakwana 200 ℃, mwinamwake kungayambitse kuwonongeka kwa zomangira ndi coil kapena ngakhale zidutswa.

5. Panthawi yogwira ntchito kapena pamene ng’anjo ilibe kanthu, chiwerengero ndi nthawi yotsegula chivundikiro cha ng’anjo ziyenera kuchepetsedwa kuchepetsa kutentha kwa kutentha ndi ming’alu yomwe imayambitsidwa ndi kuzizira kofulumira kwa ng’anjo yamoto.

6. Ng’anjoyo iyenera kukhala yodzaza kuti ipangidwe bwino, ndipo theka la ng’anjo yamoto ndiloletsedwa. Pofuna kupewa kwambiri kutentha kusiyana ndi chifukwa ming’alu.

7. Panthawi yosungunuka bwino, iyenera kusungunuka pamene ikuwonjezera zipangizo, ndipo siziloledwa kuwonjezera zinthu pambuyo poti chitsulo chosungunula chichotsedwa. Makamaka, kuwonjezereka kwachitsulo chosungunula kumayambitsa kusinthasintha kwakukulu kwachitsulo chosungunuka, ndipo chitsulo chosungunulacho chidzalowa mosavuta mu ng’anjo yosasunthika pamwamba pa mlingo wamadzimadzi, zomwe zimapangitsa kuti ng’anjo iwonongeke mwangozi.

8. Kwa ng’anjo yomangidwa kumene, ng’anjo zosachepera 3-6 ziyenera kugwiritsidwa ntchito mosalekeza, zomwe zimathandiza kupanga sintered wosanjikiza ndi mphamvu zokwanira.

9. Ngati smelting yatha, palibe chitsulo chosungunula chomwe chimaloledwa mu ng’anjo kuti chiteteze kusiyana kwakukulu kwa kutentha pakati pa kumtunda ndi kumunsi kwa ng’anjo yamoto, zomwe zingapangitse kuti crucible ikhale yovuta ndi ming’alu.
