Babban masu kera injin kashe wuta a taƙaice bayyana aikin annealing na karfe

1. Cikakken annealed

Tsari: Dumama sama da Ac3 zuwa 30-50°C → adana zafi → sanyaya zuwa ƙasa da digiri 500 tare da tanderun → sanyaya iska zuwa zafin jiki.

Manufar: don tsaftace hatsi, tsari iri ɗaya, inganta filastik da tauri, kawar da damuwa na ciki, da sauƙaƙe machining.

2. Ƙunƙarar isothermal

Tsari: dumama sama da Ac3 → adana zafi → saurin sanyaya zuwa yanayin canjin pearlite → zaman isothermal → canzawa zuwa P → sanyaya iska;

Manufa: Ibid. Amma lokaci yana da ɗan gajeren lokaci, mai sauƙin sarrafawa, kuma deoxidation da decarburization ƙananan ne. (Dace da gami karfe da manyan carbon karfe sassa tare da in mun gwada da barga supercooled A).

3. Spheroidizing annealing

Ra’ayi: shine tsari na spheroidizing siminti a cikin karfe.
