Grey cast iron mankhwala ndimchenga nkhungu kuponyera ndondomekondi CNC Machining.

Iron cast iron imatchedwa mtundu wa imvi wa fracture yomwe imapanga. Chitsulo cha imvi chimagwiritsidwa ntchito popanga nyumba zomwe kuuma kwa chigawocho kuli kofunika kwambiri kuposa mphamvu zake zowonongeka, monga zitsulo zamkati za injini zoyaka moto, nyumba zapampu, matupi a valve, mabokosi amagetsi, zolemera zowerengera ndi zokongoletsera zokongoletsera. Matenthedwe apamwamba a chitsulo cha Grey cast ndi mutu wake nthawi zambiri amagwiritsidwa ntchito popanga zophikira zachitsulo ndi ma disc brake rotor.

Zomwe zimapangidwira kuti mupeze graphic microstructure ndi 2.5 mpaka 4.0% carbon ndi 1 mpaka 3% silicon polemera. Graphite amatha kutenga 6 mpaka 10% ya voliyumu yachitsulo chotuwa. Silicon ndi yofunika kupanga chitsulo imvi mosiyana ndi chitsulo choyera, chifukwa silicon ndi graphite stabilizing element mu iron cast, kutanthauza kuti amathandiza alloy kupanga graphite m'malo carbides chitsulo; pa 3% silicon pafupifupi palibe mpweya umene umakhala ndi mankhwala osakaniza ndi chitsulo.

graphite amatenga mawonekedwe a mbali zitatu za flake. M'miyeso iwiri, ngati malo opukutidwa adzawonekera pansi pa maikulosikopu, ma graphite flakes amawoneka ngati mizere yabwino. Nsonga za flakes zimagwira ntchito ngati nsonga zakale; kotero, ndi brittle. Kukhalapo kwa ma graphite flakes kumapangitsa Grey Iron kuti ikhale yosavuta kupanga chifukwa imakonda kusweka mosavuta kudutsa ma graphite flakes. Chitsulo chotuwira chimakhalanso ndi mphamvu yabwino yonyowetsa, chifukwa chake chimagwiritsidwa ntchito kwambiri ngati maziko oyika zida zamakina.

Kuponyera mchenga kumagwiritsa ntchito mchenga wobiriwira (mchenga wonyowa) kapena mchenga wouma kupanga makina owumba. Kuponyera mchenga wobiriwira ndi njira yakale yoponyera yomwe imagwiritsidwa ntchito m'mbiri. Popanga nkhungu, mapangidwe opangidwa ndi matabwa kapena zitsulo ayenera kupangidwa kuti apange dzenje. Chitsulo chosungunulacho chimatsanulira mu mtsempha kuti apange zoponyera pambuyo pozizira ndi kulimba. Kuponya mchenga ndikotsika mtengo kuposa njira zina zopangira nkhungu komanso gawo loponyera ma unit. Mchenga kuponyera, nthawizonse zikutanthauza wobiriwira mchenga kuponyera (ngati palibe kufotokoza wapadera). Komabe, masiku ano, njira zina zoponyamo zimagwiritsanso ntchito mchenga kupanga nkhungu. Ali ndi mayina awoawo, mongachipolopolo nkhungu kuponyera, utomoni wa furan wokutira mchenga (palibe mtundu wophika),kutaya thovundi kuponya vacuum.
