Nzira yekunyungudutsa simbi uye zvimedu simbi mu induction kunyunguduka muvira

Before the induction furnace is charged, the residue in the furnace should be removed, and the damage of the furnace lining should be checked. The severely damaged parts have become black due to rapid cooling and should be repaired. The grain size of the repairing material should be slightly smaller than that of the knotted material, and the binder used should be slightly more. Large-scale furnaces that are severely damaged can be hoisted into the furnace iron mold to fill in knots.

Sezvo tembiricha yehuni yekupinza inodonha nekukurumidza mushure mekutapa, inofanirwa kubhadhariswa nekukurumidza uye inofanira kuzadzwa nemadhiramu zvakanyanya sezvinobvira. Kuti ikurumidze kunyunguduka, zvinhu zvinofanira kugoverwa zvinonzwisisika maererano nekugoverwa kwekushisa muchoto. Kugoverwa kwekushisa muchoto chekupinza kunoratidzwa muMufananidzo 4-25. Nekuda kwekuita kweganda rezvino, nzvimbo yakatenderedza yekoramu yezvinhu (zone I) padhuze nemadziro evolute inzvimbo yekupisa yakanyanya.

Pazasi nepakati (I, TT zone) ine zvishoma zvishoma kupisa kupisa, inova yakakwirira tembiricha zone, uye chikamu chepamusoro (IV zone) ine magineti mashoma uye kurasikirwa kukuru kwekupisa, inova yakaderera tembiricha zone.

Kuti ugadzire slag pamberi, 1% yemidziyo ye slag nehuremu inogona kuwedzerwa pasi pechoto isati yachaja, lime uye fluorite zvinowedzerwa muvira realkaline, uye girazi cullet inowedzerwa kuvira re acid.

Pakutanga kwekunyunguduka, nokuti inductance uye capacitance pamutsara haigoni kuenzaniswa nekukurumidza uye zvakakodzera, ikozvino haina kugadzikana, saka inogona kupiwa simba rakaderera munguva pfupi. Kana iyo yazvino yagadzikana, inofanirwa kuchinjirwa kune yakazara mutoro kutapurirana. Munguva yekunyunguduka, iyo capacitor inofanira kugara ichigadziriswa kuchengetedza midziyo yemagetsi ine simba guru. Mushure mokunge mutero wanyungudutswa zvachose, simbi yakanyungudutswa inopisa kusvika kune imwe nzvimbo, uye ipapo simba rekuisa rinoderedzwa maererano nezvinodiwa zvekunyunguduka.

Nguva yakakodzera yekunyunguduka inofanira kudzorwa. Kana nguva yekunyunguduka ipfupi, zvinokonzeresa kuomerwa mukusarudzwa kwevoltage uye capacitance. Kana yakanyanyisa kureba, ichawedzera kurasikirwa kwekupisa kusina maturo. Mucheka usina kukodzera kana kuti ngura yakawandisa muchoto chevira ichakonzera “bridging” chiitiko, chinofanira kugadziriswa nenguva. “Bridge” rinodzivirira zvinhu zvisina kunyunguduka kumusoro kuti zvisawira musimbi yakanyungudutswa, ichidzika yuhua, uye kupisa kwepasi kwesimbi yakanyungudutswa kunogona kukuvadza zviri nyore jira rechoto, uye kuchaitawo kuti simbi yakanyungudutswa itore yakawanda. zvegasi.

Pamusana pekukurudzira kwemagetsi, pakati pesimbi yakanyungudutswa inoputika, uye slag inowanzoyerera kusvika kumucheto wecrucible uye inonamatira kumadziro evira. Nokudaro, iyo slag inofanira kuramba ichiwedzerwa maererano nemamiriro echoto panguva yekunyunguduka.
