Imigaqo yeNtlawulo:T / T, LC.
Ukuhanjiswa: iintsuku ezi-7-15 emva kwentlawulo.
Umphezulu: Iityhubhu ziza kuvanishi (Ngaphandle kuphela) ukunqanda umhlwa.
Ukumakishwa: iBanga eliMgangatho + leNsimbi + Ubungakanani + Ubushushu Hayi + iLoti yeNombolo.
Ukupakishwa: Iinyanda (ezinehexagonal), iibhokisi zoMthi, iiCreyithi (intsimbi/umthi) okanye njengoko kufuneka.
(1)Indlela yokwenza intsimbi
Isinyithi senziwa ngesithando sombane, isiguquli seoksijini okanye indlela yokuvula iziko.
(2)Indlela yokwenziwa kwetyhubhu engenanto
I-tube engenanto inokuveliswa ngendlela eshushu, kunye ne-billet eqhubekayo yokuphosa okanye i-ingot yensimbi nayo ingasetyenziswa.
(3)Indlela yokuvelisa umbhobho wentsimbi
Umbhobho wensimbi unokuveliswa ngokutshisa okutshisa (i-extrusion, isandiso) okanye umzobo obandayo (i-rolling) indlela engenamthungo.

Imibhobho yentsimbi enobubanzi obungaphandle obungaphezulu kwe-22mm ukuya kwi-400mm kunye nobukhulu bodonga obungekho ngaphezu kwe-10mm iya kufakwa kuvavanyo lokucaba.
(3)Uvavanyo oluvuthayo
Umbhobho wensimbi kunye nobukhulu bodonga obungekho ngaphezu kwe-8 mm unokuvavanywa kwi-flare test kunye ne-taper ephezulu ye-30 °, 45 ° okanye 60 °.
(4) Uvavanyo lokugoba
Imibhobho yentsimbi enobubanzi obungaphandle obungekho ngaphezu kwe-22 mm iya kufakwa kuvavanyo lokugoba.
(5)Uvavanyo olungonakalisi
Ngokweemfuno zomthengi, umbhobho wensimbi uya kuvavanywa nge-ultrasonically nganye.
Indawo yangaphakathi nangaphandle yombhobho wensimbi ayinayo i-cracks, i-folds, i-creases, i-crusting okanye ukwahlukana, kwaye ezi ziphene kufuneka zisuswe ngokupheleleyo.Ubunzulu bokucoca abuyi kudlula ukutenxa okungalunganga kobunzima bodonga lwegama, kwaye ubukhulu bodonga lokwenene kwindawo yokucoca abuyi kuba ngaphantsi kobuncinci obuvunyelwe ludonga.
Ukupakishwa, ukuphawula kunye neenkcukacha zomgangatho weepayipi zensimbi ziya kuhambelana nemimiselo ye-GB / T 2102.
