Precautions for the operation of coreless induction furnace for conventional foundry

The following precautions are well-known to melters and foundries, and are common knowledge not only for coreless induction furnaces but also for all metal smelting operations. This is just for general knowledge and does not involve all types of operations. These matters should be explained clearly and appropriately expanded or perfected by a specific operator.

Kunyungudutsa nekukanda mabasa kunofanirwa kugumira kune vashandi vane zvitupa zvetifiketi, kana vashandi vanokwanisa mukudzidziswa kwefekitori uye kuongorora, kana mashandiro ari pasi pekuraira kwevanokwanisa mainjiniya uye vashandi vehunyanzvi mufekitori.

Vashandi vepasaiti vanofanirwa kugara vakapfeka magirazi ekuchengetedza ane mafuremu ekudzivirira, uye kushandisa mafirita akakosha kana vachiona simbi dzinopisa.

4. Vashandi vanoshanda panzvimbo yemoto kana pedyo vanofanira kupfeka mahovhorosi anodzivirira kupisa uye asingatsvi. Synthetic chemical fiber (nylon, polyester, etc.) zvipfeko hazvifaniri kupfekwa pedyo nemoto.

5. Chigadziko chevira chinofanira kuongororwa kakawanda pane imwe nguva yenguva kudzivirira “kupera simba”. Mushure mekutonhora, tarisa chigadziko chevira. Kana ukobvu hwebindu rechoto (kusanganisa asbestos board) isingasviki 65mm-80mm mushure mekupfeka, choto chinofanira kugadziriswa.

6. Kuwedzera zvinhu zvinofanira kuchenjerera kudzivisa “mabhiriji” ezvigadzirwa. Kupisa kwepamusoro-soro kwesimbi kumativi ose e “mabhiriji” kuchaita kuti kuparara kwevheni yevira kukurumidza.

7. Iyo itsva coreless induction furnace inofanira kugadzirwa nezvinhu zvakakodzera, zvakakodzera kuti simbi inyungudutswe, uye iomeswe zvachose isati yawedzera zvinhu zvekunyunguduka. Iyo zvinhu sintering mirau inofanira kunyatsotevera chinyorwa ichi.

8. Zvinhu zvisinganyanyi kunyunguduka zvakadai sealuminium uye zinc zvinofanira kuwedzerwa nekuchenjerera kune zvinwiwa zvinopisa zvakanyanya sesimbi. Kana iyo yakaderera melting point additives ikanyura isati yanyunguduka, inofashaira zvine chisimba uye inokonzera kufashukira kana kunyange kuputika. Ngwarira zvakanyanya paunenge uchiwedzera galvanized tubular charge.

9. Mutero unofanirwa kunge wakaoma, usina zvinhu zvinopisa, uye kwete kunyanya kusvibiswa kana kunyorova. Kufashaira zvine chisimba kwemvura kana zvinobatika pakuchaji kunogona kukonzera simbi yakanyunguduka kuti ifashukire kana kuputika.

10. Movable quartz crucibles inogona kushandiswa kana ese simbi uye coreless induction furnaces ari akakodzera saizi. Izvo hazvina kugadzirirwa kunyungudika kwekushisa kwesimbi yesimbi. Chirevo chemugadziri wekuita chinofanira kunge chiri gwara rekushandisa crucible.

11. Kana iyo simbi inotakurwa ichienda kune crucible, mativi uye pasi pe crucible inofanira kutsigirwa nebhakiti. Rutsigiro runofanira kuedza kudzivirira crucible kubva pakutsvedza kunze panguva yekukanda.

12. Iyo yakakodzera kunyungudutsa chemistry ruzivo inofanira kunzwisiswa. Semuyenzaniso, kuita kwemakemikari sekuvirisa kabhoni zvine chisimba kunogona kukonzera kukuvara kwemidziyo uye kukuvara kwemunhu. Iyo tembiricha yemushonga wekupisa haifanirwe kudarika kukosha kunodiwa: Kana tembiricha yesimbi yakanyungudutswa yakanyanyisa, hupenyu hwebindu rechoto huchadzikiswa zvakanyanya, nekuti zvinotevera zvinozoitika mu acid firnace lining: SiO2 + 2 (C) [Si] +2COKuita uku kunosvika 1500℃ musimbi yakanyungudutswa Iyo iri pamusoro yakaenderera mberi nekukurumidza, uye panguva imwechete iyo kuumbwa kwesimbi yakanyungudutswa kwakachinjawo, iyo kabhoni element yakatsva, uye silicon yemukati yakawedzera.

13. Nzvimbo yekugamuchira inofanira kuchengetedza vhoriyamu isina mvura. Kubata kwesimbi inopisa uye mvura kunogona kukonzera kuputika kwechisimba uye kukonzera kukuvara kwemunhu. Zvimwe zvisaririra zvinogona kudzivirira simbi yakanyungudutswa kuti isayerera ichipinda mutangi rinofashukira kana kuti kubatidza moto.

14. Tangi yekufashukira inofanira kunge yakagadzirira kugashira simbi yakanyungudutswa chero nguva apo coreless induction furnace iri kushanda. Kurasika kunogona kuoneka pasina yambiro. Panguva imwecheteyo, kana iyo coreless induction furnace ichifanira kudururwa nekukurumidza sezvinobvira uye mbiya (ladle) isina kukodzera, iyo coreless induction choto inogona kukandwa yakananga mutangi rinofashukira.

15. Vese vashandi vanodyara nhengo dzemuviri, majoini, ndiro kana zvimwewo zvakadaro vanofanira kugara kure nechoto chipi nechipi chisina coreless induction. Iyo magineti padhuze nemudziyo inogona kukwezva ikozvino pane chero simbi inoiswa. Vanhu vane moyo pacemakers vari panjodzi zvakanyanya uye vanofanirwa kugara kure nechero coreless induction choto.
