A: Ku gipimo kimwe cy'umuvuduko, umuyoboro upfutse (urugero, T91 + Alloy 28) ukunze kugurwaKugabanukaho 40-50%kurusha umuyoboro wa Alloy 28 ukomeye ufite ubugari bungana bwa OD n'inkuta. Kuri SA-210+Incoloy 825, kuzigama bishobora kuba 50-60% ugereranije na 825 ikomeye. Ingano nyayo iterwa n'ubugari bw'igipfundikizo n'ibikoresho by'ibanze.
Q12: Ese ufite uburambe mu gutanga icyemezo cya VdTUV (urugero, kuri Incoloy 825 kuri VdTUV 432)?
A: Yego. Twahaye imiyoboro ipfundikiye ku bakozi b'inganda bo mu Budage bakeneye uruhushya rwa VdTUV. Dushobora gusaba umugenzuzi wemewe kugira ngo yemererwe ibikoresho bya VdTUV kandi dutange inyandiko zikenewe.
Q13: Impera z'umuyoboro zirangira zite?
A: Ibisanzwe: byaciwe kare, byakuweho ubushyuhe. Ubusa: byaciwe (30-35°), bifite insinga (zo gufatanya n'imashini), cyangwa bifite imigozi. Impera zabyo zishobora gutangwa naGusiga amavuta muri CRA(urwego rw'icyuma gihuye n'icyuma cyo gusudira ku ruhande rw'umusenyi) kugira ngo hirindwe ko amazi yagabanuka mu gihe cyo gusudira mu murima. Nyamuneka sobanura.
Q14: Ubunini bw'ubugari bw'ubudodo bushobora gukoreshwa mu gupfunyika bungana iki kugira ngo habeho uburyo bworoshye bwo gupfunyika?
A: 1.5 mm ni yo ntarengwa dufite ku muyoboro udafite umugozi urimo umugozi. Ku bugari bw'umuyoboro uri munsi ya 1.5 mm, icyizere cyo gufatanya kiragabanuka; twakugira inama yo gukoresha umuyoboro udafite umugozi urimo umugozi. Ku bijyanye n'uburyo bwinshi bwo kwangirika, 2.0 mm 2.5 ni byo bisanzwe.
Q15: Ese hari uburebure ntarengwa ku muyoboro udafite umugozi?
A: Ubushobozi bwo gusohora ibintu bugabanya uburebure bumwe kugeza kuri metero 15 ku mpande ziri munsi ya mm 100. Ku mpande nini, uburebure ntarengwa bukunda kuba bugufi (metero 12). Niba hakenewe uburebure burebure (urugero, mu gukurura), dushobora gusuzuma uburyo bwo gukurura ibice birebire bikonje bivuye mu miyoboro y’amazi yakuwemo.
11. Vugana na Womic Steel kugira ngo ubone ibiciro bya tekiniki
Ku bibazo bijyanye n'imiyoboro idafite imitako ikozwe mu byuma - ishyushye cyane, ikonje, ishyushye kandi ivanzwe - ohereza urutonde rw'ibikenewe (inkingi + ipfundikizo, ingano, uburebure, urwego rw'impamyabushobozi). Tuzagusubiza tuguhe igiciro cya tekiniki kirambuye, igihe cyo gutanga, n'igiciro.
