Ukunyamezelana

Ukuphambuka okuvumelekileyo kobubanzi bangaphandle beetyhubhu zentsimbi

Imfuneko yoVavanyo

Uvavanyo lokuthamba

Iityhubhu zentsimbi ezinobubanzi obungaphandle obungaphezulu kwama-22 mm ukuya kuthi ga kwi-400 mm, kunye nobukhulu bodonga obungaphezulu kwe-10 mm kufuneka zivivinywe ukuba zithe tyaba. Emva kokuba iisampulu zithe tyaba

Uvavanyo lokugoba

Iityhubhu zentsimbi ezinobubanzi obungaphandle obungadluli kwi-22 mm kufuneka zivivinywe ukugoba. I-engile yokugoba yi-90o. Irediyasi yokugoba iphindwe kathandathu kunobubanzi obungaphandle bombhobho wentsimbi. Emva kokugoba isampuli, akukho mingxunya okanye imifantu evumelekileyo ukuba ivele kwisampuli.

Uvavanyo lwe-macroscopic

Kwiityhubhu zentsimbi ezenziwe ngokuthe ngqo ziibhilethi ezicwangcisiweyo rhoqo okanye ii-ingots zentsimbi, iqela elibonelela ngeenkonzo kufuneka liqinisekise ukuba akukho mabala amhlophe, ukungcola, amaqamza omoya angaphantsi komhlaba, amabala entloko okanye ukugalelwa kwizicubu ze-macroscopic ze-acid pickled zetyhubhu ye-billet okanye yentsimbi.

Uhlolo olungatshabalalisiyo

Ngokwesicelo seqela elifuna uncedo, esixoxiswana ngaso phakathi kwamaqela anikezelayo nafuna uncedo kwaye siboniswe kwisivumelwano, ukufunyanwa kweziphene ze-ultrasonic kunokwenziwa ngokwahlukeneyo kwiityhubhu zentsimbi. Isiphene esijikelezayo setyhubhu yesampulu yesalathiso kufuneka sihlangabezane neemfuno zebanga lokwamkelwa emva kokuhlolwa elichazwe kwi-GB/T 5777-1996.
