Ukuza kuthi ga ngoku, uluhlu lwezinto ezithengiswayo luhlaziywa rhoqo kwaye lwatsala abathengi abavela kwihlabathi liphela. Iinkcukacha ezinzulu zinokufumaneka kwiphepha lethu lewebhu kwaye uya kubonelelwa ngenkonzo yomcebisi esemgangathweni liqela lethu emva kokuthengisa. Baza kwenza ukuba kwenzeke ukuba ufumane ulwazi olupheleleyo malunga nezinto zethu kwaye wenze uthethathethwano olwanelisayo. Amashishini amancinci jonga kumzi-mveliso wethu eUganda nawo angamkeleka nangaliphi na ixesha. Ndiyathemba ukufumana imibuzo yakho ukuze ufumane intsebenziswano eyonwabisayo.
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.
