Tsopano mafakitale ambiri opanga mafakitale adzagwiritsa ntchito zitsulo zosapanga dzimbiri zachitsulo zopangira chingwe chopangira, 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 ndi 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 dilute 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 kuwotcha, wamba mpweya zitsulo kapena chitsulo kupanga mkati masekondi angapo A wosanjikiza pamwamba zitsulo mkuwa, ndi pamwamba pa point test chitsulo chosapanga dzimbiri sichitulutsa mvula yamkuwa kapena kuwonetsa mtundu wamkuwa.
4, njira yoyesera ya sulfuric acid
Kumizidwa kwa sulfuric acid wa chitsulo chosapanga dzimbiri kumatha kusiyanitsa 302 ndi 304 kuchokera ku 316 ndi 317. Mphepete mwachitsanzo iyenera kukhala yabwino kwambiri, kenako kutsukidwa ndikudutsa mu sulfuric acid ndi kuchuluka kwa 20% ~ 30% ndi kutentha kwa 60. ~ 66 ℃ kwa theka la ola.Pamene voliyumu ndende ya sulfuric acid solution ndi 10% ndi kutentha kwa 71 ℃,302 ndi 304 kumizidwa mu yankho, chitsulo mofulumira dzimbiri ndi kutulutsa thovu ambiri, ndipo chitsanzo amakhala wakuda mu mphindi zochepa. Zitsanzo zazitsulo za 316 ndi 317 sizimawonongeka kapena zowonongeka pang'onopang'ono (palibe thovu), kuyesa mkati mwa mphindi 10 ~ 15 sikusintha mtundu.Kuyesa kungakhale kolondola ngati chitsanzo chodziwika bwino chikugwiritsidwa ntchito poyerekeza.
