Tsopano mafakitale ambiri opanga mafakitale adzagwiritsa ntchito chingwe chachitsulo chosapanga dzimbiri chachitsulo chopangira kupanga, kuti azindikire zitsulo zosapanga dzimbiri zabodza, njira zina ndi njira zomwe zingatengedwe. Mitundu yotsatirayi ya njira zozindikiritsira zalembedwa ndiGepair tensile mauna.
1, njira yoyesera maginito
Njira yoyesera maginito ndiyo yoyambirira komanso yodziwika bwino kwambiri pakati pa chitsulo chosapanga dzimbiri cha austenitic ndi chitsulo chosapanga dzimbiri cha ferritic ndiye njira yosavuta, chitsulo chosapanga dzimbiri cha austenitic sizitsulo zamaginito, koma pakatha mphamvu yayikulu kuzizira kudzakhala ndi maginito wofatsa; zitsulo ndi zitsulo zolimba maginito.
2. Mayeso a nitric acid point
Chosiyanitsa cha chingwe chachitsulo chosapanga dzimbiri ndicho kukana kwa dzimbiri kokhazikika komanso kusungunula nitric acid, zomwe zimapangitsa kuti zisiyanitsidwe mosavuta ndi zitsulo zina zambiri kapena ma aloyi.Komabe, zitsulo za carbon 420 ndi 440 zimawonongeka pang'ono poyesa nitric acid point, ndipo zitsulo zopanda chitsulo zimawonongeka nthawi yomweyo mu nitric acid, pamene kuchepetsa nitric acid imakhala ndi mphamvu zowonongeka pa carbon steel.
3, Copper sulfate point test
Copper sulphate mfundo kuyesa mofulumira kusiyanitsa pakati wamba mpweya zitsulo ndi chophweka njira ya mitundu yonse ya zosapanga dzimbiri chingwe waya chingwe, ntchito ndende ya yankho la mkuwa sulphate ndi 5% - 10%, pamaso mayesero mfundo, malo mayeso. ayenera bwinobwino kuchotsa mafuta ndi zonyansa zina, nsalu kapena zofewa akupera kupukuta ndi popera makina ang'onoang'ono, ndiyeno kuyesa m'malovu kuyatsa, wamba mpweya zitsulo kapena chitsulo kupanga mkati mwa masekondi pang'onoA wosanjikiza pamwamba zitsulo mkuwa, ndi pamwamba pa mfundo mayeso zitsulo zosapanga dzimbiri sizitulutsa mpweya mkuwa kapena kusonyeza mkuwa mtundu.
4, njira yoyesera ya sulfuric acid
Kumizidwa kwa sulfuric acid wa chitsulo chosapanga dzimbiri kungasiyanitse 302 ndi 304 kuchokera ku 316 ndi 317. Mphepete mwachitsanzo iyenera kudulidwa bwino, kenako kutsukidwa ndi kupyola mu sulfuric acid ndi kuchuluka kwa 20% ~ 30% ndi kutentha kwa 60. ~ 66 ℃ kwa theka la ola. Pamene voliyumu ya sulfuric acid solution ndi 10% ndikutenthedwa mpaka 71 ℃,302 ndi 304 imamizidwa mu yankho, chitsulocho chimawonongeka mofulumira ndipo chimapanga thovu zambiri, ndipo chitsanzocho chimakhala chakuda mumphindi zochepa. 316 ndi 317 zitsulo zitsanzo si dzimbiri kapena dzimbiri pang'onopang'ono (palibe thovu), mayeso mkati 10 ~ 15 mphindi kuchita osasintha mtundu.Kuyesa kungakhale kolondola kwambiri ngati chitsanzo chodziwika bwino chikugwiritsidwa ntchito poyerekezera.
