Isishwankathelo
Isicelo
Isetyenziswa ikakhulu ukwenza umgangatho ophezulu wekhabhoni yentsimbi, umbhobho webhoyila woxinzelelo oluphantsi, umbhobho oshushu oshushu kakhulu ongenamthungo wecarbon.
IBanga eliPhambili
Ibakala eliphezulu carbon yesakhiwo steel: 10 #,20 #

Imfuneko yoVavanyo
Uvavanyo lokucaba
Iityhubhu zentsimbi ezinobubanzi obungaphezulu kwe-22 mm ukuya kutsho kwi-400 mm, kunye nobukhulu bodonga obungaphezulu kwe-10 mm kufuneka zenze uvavanyo lokucaba. Emva kokuba iisampulu zityatyekwe
Ukugoba uvavanyo
Iityhubhu zentsimbi ezinobubanzi obungaphandle obungekho ngaphezulu kwe-22 mm kufuneka zingene kuvavanyo lokugoba. I-engile yokugoba yi-90o. I-radius yokugoba ngamaxesha angama-6 ububanzi bangaphandle bombhobho wensimbi.Emva kokugoba isampuli, akukho kuphazamiseka okanye ukuqhekeka kuvunyelwe ukuba kubonakale kwisampuli.
Uviwo lweMacroscopic
Kwiityhubhu zentsimbi ezenziwe ngokuthe gqolo ngokuphoswa kweebhilidi okanye ii-ingots zentsimbi, iqela elinikezelayo kufuneka liqinisekise ukuba akukho mabala amhlophe, ukungcola, amaqamza omoya angaphantsi komhlaba, amabala okakayi okanye ukwaleka kwi-asidi evutshiweyo ye-macroscopic tissue ye-billet okanye ityhubhu yentsimbi.
Ukuhlolwa okungonakalisi
Ngokwesicelo seqela elifunayo, elithe ke lixoxisana phakathi kwamaqela anikezelayo kunye nalawo afunayo kwaye aboniswe kwisivumelwano, ukufumanisa impazamo ye-ultrasonic inokwenziwa ngabanye kwiityhubhu zetsimbi. I-longitudinal manual defect ye-tube yesampuli yereferensi kufuneka ihlangabezane neemfuno zokwamkelwa emva kokuhlolwa kwebakala C8 elichazwe kwi-GB / T 5777-1996.
