Kukanda Zvakawanda Zvikanganiso

Zvikamu zvitanhatu zvakajairika kuremara'zvinokonzera uye kudzivirira nzira, kwete kuunganidzazvichavekurasikirwa kwako! ((Chikamu 1)

Kukandira maitiro ekugadzira, kupesvedzera zvinhu uye kukanganisa kukanda kana kutadza hazvidzivisike, izvo zvinowanzounza kurasikirwa kukuru kune bhizinesi. Nhasi, ini ndichasuma mhando nhanhatu dzezvakajairwa kukanganisa uye mhinduro, ndichivimba kuti inobatsira kune yekutanga indasitiri.

1Porosity (bubbles, choke gole, Pocket)

1)Features:Porosity iripo mukati menzvimbo yekukanda kana maburi, akatenderedzwa, ovha kana asina kuumbwa, dzimwe nguva ma pores akawanda anoumba mhepo yakawanda pasi peganda inowanzoita pear. Choke gomba chimiro chisina kujairika uye hutsinye hwepamusoro. Homwe inzvimbo yakakomberedzwa panzvimbo yakatsetseka. Bright pore inoonekwa nekuongorora, iyo pinhole inogona kuwanikwa mushure mekugadzira michina.
2)Zvinokonzera:
l Mold preheating tembiricha yakadzikira, simbi yemvura inopfuura nekudurura system ichitonhora nekukurumidza.
l Yakashata dhizaini yekupedza mold, magasi haagone kuburitswa asina kuvharwa.
l Pendi haina kunaka, yakashata inopera pachayo, kusanganisira yake volatilization kana decomposition magasi.
l Mold cavity pamusoro maburi & makomba, mushure mekunge simbi yemvura yadirwa mumakomba, kukurumidza kuwedzera kwegomba gasi rakadzvanywa simbi yemvura kuita gomba rinodzipwa.
l Mold cavity pamusoro mukuora uye haina kucheneswa.
l Raw zvinhu (cores) zvakachengetwa zvisina kunaka, pasina preheating isati yashandiswa.
l Yakashata yekudzikisa mumiriri, kana dosi isina kufanira kana kushanda kwakashata.
3) Nzira yekudzivirira:
l mold kuzara preheat, coating (graphite) particle size haifaniri kunge yakanyanyisa uye kuve nekufema kuri nani.
l Shandisa tilt casting nzira yekukandira.
l Zvigadzirwa zvinofanirwa kuchengetwa munzvimbo yakaoma uye inofefetera, kana ichishandiswa preheat.
l Sarudza iyo deoxidation mhedzisiro yakanaka yekudzikisa mumiriri (magnesium).
l Tembiricha yekudurura haifanirwe kunge yakanyanya kukwirira.

2 Shrinkage

1) Zvimiro:The shrinkage igomba repamusoro rinenge riri pamusoro kana mukati mekukanda. Kudzikira zvishoma kwakapararira kudiki shrinkage yezviyo zvakakasharara, kazhinji yakaitika mukukanda padyo nemumhanyi, midzi yekusimuka, nzvimbo dzakakora, ukobvu hwekutamisa madziro uye ndege huru.

2) Zvikonzero:
l Mold inoshanda tembiricha haina kusangana negwara rekusimbisa zvinodiwa.
l Sarudzo isina kunaka yekupfeka, ukobvu hwekuputira haudzorwe muzvikamu zvakasiyana.
l Nzvimbo yekukanda mukugadzira mold haina kukodzera.
l Kudira dhizaini yekusimudza yatadza kuzadzisa zvizere basa.
l Tembiricha yekudurura yakadzikira kana yakanyanya.

3)Nzira yekudzivirira:
l Kuwedzera kupisa kwema molds.
l Kugadzirisa ukobvu hwekufukidzira uye kupfeka kwakapfapfaidzwa zvakafanana. Kana pendi inodonha uye inoda kugadzira, haifanire kuumba pendi yemuno kuunganidza.
l Kudziyisa mold yemuno kana kuvharisa kwenzvimbo uchishandisa thermal insulation zvinhu.
l Seta inopisa nzvimbo yemhangura block uye itonhore yemunharaunda.
l Kugadzira radiator muforoma, kana nekukasira kutonhora munzvimbo dzakaita semvura, kana kumwaya mvura kunze kwekuumbwa.
l Iine detachable unloading chilling chidimbu, akaiswa alternately mukati megomba, kuitira kudzivirira kana ichienderera kugadzirwa, pachayo kutonhora hakuna kukwana.
l Kugadzira mudziyo wekumanikidza pane riser ye mold.
l Kugadzira gating system nenzira kwayo, kusarudza tembiricha yekudurura yakakodzera.

3 Slag makomba (flux slag uye simbi oxide slag)

1)Zvinhu:Iyo slag gomba rakajeka kana rima maburi mukukanda, zvese kana chikamu chegomba chakazadzwa ne slag. Chimiro chisina kujairika, diki poindi ye flux slag haisi nyore kuwana, mushure mekubviswa kwe slag, wobva waratidza gomba rakatsetseka. Zvakawanda zvakagoverwa muchikamu chepasi chenzvimbo yekukanda, padhuze nemumhanyi kana kona yekukanda, oxide slag inonyanya kugoverwa mugedhi remambure padhuze nepamusoro, dzimwe nguva mumaflakes kana gore risingaenzaniswi rine sandwich yakaunyana kana sheet, kana flocculent castings, kazhinji inotsemuka kubva sandwich ine oxide. Ndicho chimwe chezvikonzero zvinokonzera kukanda mitswe.

2)Chikonzero:Iyo slag gomba inonyanya kukonzerwa nekunyungudika kwealloy uye kukanda maitiro (kusanganisira isiriyo gating system dhizaini), mold pachayo haikonzeri gomba re slag, uye kushandisa simbi mold ndiyo imwe yenzira dzinoshanda dzekudzivisa slag.

3) Nzira yekudzivirira:
l Kugadzira gating system nemazvo, kana kushandisa cast fiber sefa.
l Kushandisa nzira yekudira yakarerekera.
l Kusarudza mumiriri wefusion uye kunyatso kudzora mhando.

Zvimwe zvitatu zvekukanda zvirema zvichaenderera mberi svondo rinouya.Thanks.
