Zinthu zisanu zofunika zimakhudza kuwala kwa zitsulo zosapanga dzimbiri chubu pambuyo annealing

Kaya kutentha kwa annealing kufika pa kutentha komwe kumatchulidwa, chithandizo cha kutentha kwa chitsulo chosapanga dzimbiri chimatengedwa kuti ndi chithandizo cholimba cha kutentha, ndiko kuti, anthu omwe amatchedwa "annealing", kutentha kwa 1040 ~ 1120 ℃ (muyezo waku Japan). Mutha kuyang'ananso kudzera pa dzenje loyang'ana ng'anjo yowotchera, malo olowerachubu chachitsulo chosapanga dzimbiriayenera kukhala incandescent, koma palibe kufewetsa drooping.

Annealing atmosphere, kawirikawiri ndi ntchitowa hydrogen weniwenimonga annealing mlengalenga, mlengalenga chiyero ndi bwino kuposa 99,99%, ngati mlengalenga ndi mbali ina ya mpweya inert, chiyero akhoza kukhala m'munsi pang'ono, koma sayenera muli kwambiri mpweya, nthunzi madzi.

Kulimba kwa thupi la ng'anjo, ng'anjo yoyaka moto iyenera kutsekedwa, yotalikirana ndi mpweya wakunja; Ndi haidrojeni monga gasi woteteza, mpweya umodzi wokha ndi wotseguka (kuti uyatse haidrojeni yotulutsidwa). Njira yoyendera ingagwiritsidwe ntchito mu ng'anjo yowotchera ndi madzi a sopo mumpata uliwonse wolumikizana, kuti muwone ngati mpweya ukuyenda; Chimodzi mwazosavuta kuthawa malowa ndi ng'anjo yowotchera mu chitoliro ndi kunja kwa chitoliro, malowa ndi osavuta kwambiri kuvala mphete yosindikizira, kuti afufuzidwe nthawi zambiri ndikusinthidwa nthawi zambiri.

Kuteteza mpweya kukakamiza, Pofuna kupewa yaying'ono kutayikira, mpweya zoteteza mu ng'anjo ayenera kukhala ndi ena zabwino kuthamanga. Ngati ndi gasi woteteza haidrojeni, nthawi zambiri amafunika kukhala wopitilira 20kBar.

Nthunzi yamadzi mu ng'anjo, Kumbali imodzi, fufuzani ngati ng'anjoyo yauma, ng'anjo yoyamba, zinthu za ng'anjo ziyenera kuuma; Awiri ndichitoliro chosapanga dzimbirimu ng'anjo kaya otsala madzi ochuluka, makamaka ngati pali dzenje pamwamba pa chitoliro, musati kutayikira, apo ayi ng'anjo mpweya wawonongeka.

Ndikufuna kudziwa kuti, mawu abwinobwino, mutatha kutsegula ng'anjo iyenera kubwereranso mamita 20, chubu chachitsulo chosapanga dzimbiri cha kumanzere ndi kumanja chidzayamba kuwala, chowala chidzakhala chowala chomwe chimasonyeza kuwala.
