Iinduku zobheduzizinto ezimilise okwentonga ezenziwe ngobhedu nezinc alloys, ezithiywe ngombala wazo omthubi.I-Brass enomxholo wobhedu we-56% ukuya kwi-68% inendawo yokunyibilika ye-934 ukuya kwi-967 degrees.I-Brass ineempawu ezilungileyo zoomatshini kunye nokumelana nokunxiba, kwaye ingasetyenziselwa ukwenza izixhobo ezichanekileyo, iinxalenye zenqanawa, iigobolondo zemipu, iinxalenye zemoto, izixhobo zonyango, izixhobo zombane kunye nezixhobo ezahlukeneyo zokuxhasa oomatshini, amakhonkco egiya ye-synchronizer yemoto, iimpompo zaselwandle, iivalvu, iinxalenye zesakhiwo, izixhobo zokungqubana, njl.
Iintsimbi zobhedu ezinomxholo ohlukeneyo we-zinc nazo ziya kuba nemibala eyahlukileyo.Ngokomzekelo, ukuba umxholo we-zinc u-18% -20%, uya kuba bomvu-ophuzi, kwaye ukuba umxholo we-zinc u-20% -30%, uya kuba bomvu-ophuzi.Ukongezelela, ubhedu lunesandi esikhethekileyo xa sibethwa, ngoko ke iigongs zaseMpuma, amacangci, iintsimbi, iimpondo kunye nezinye izixhobo zomculo, kunye nezixhobo zobhedu zaseNtshona zonke zenziwe ngobhedu.
Yiyiphi imisebenzi ethile yokulawula umgangatho weentonga zobhedu?
1. Isixhobo sokumisa ibhande lobhedu kufuneka sihlolwe kwaye sivunywe ngumphathi ngaphambi kokuthululelwa kwekhonkrithi.
2. Umgangatho we-welding we-belt belt joints kufuneka uhlolwe.Xa umphathi ecinga ukuba kuyimfuneko, uhlolo lokuvuza kweoli kufuneka lwenziwe.Emva kokuphumelela uvavanyo, ukungcola kweoli kufuneka kucocwe.
3. Isikhokelo sefomwork kufuneka simiswe ngokuqinileyo, kwaye ifomwork emacaleni omabini ephepha kufuneka ixhaswe ngu "Ω” imilo okanye ezinye izinto ezixhasayo ukuphepha ukulungelelaniswa kunye nokuvuza kodaka ngenxa yokuguqulwa kwefomwork.
4. I-template ekhethekileyo kufuneka isetyenziswe kwibhanti yobhedu ukuqinisekisa ukuba ishidi libekwe ngokuqinileyo kwaye amajoyina awavuzi.
5. Ngethuba lenkqubo yokuthululela, gwema ukuqokelela kwee-aggregates ezinkulu kwibhande lobhedu, kwaye ungcangcazele ngokucophelela ukuze uqinisekise ukuba ikhonkrithi kwi-joint i-dense.
6. Lungiselela iinkqubo zokuthululela kunye nokugubha ngokufanelekileyo, kwaye ubeke ingqalelo ukuphepha ukuxinwa kwegazi kwibhande lobhedu.
7. Ngethuba lenkqubo yokugalela ikhonkrithi, ikontraka kufuneka ilungiselele abasebenzi abakhethekileyo ukuba bahlole kwaye balawule.Umphathi kufuneka aqinise ukuhlolwa kwamacandelo, kwaye ukuba kukho ukuphambuka kufunyenwe, ikontraka kufuneka iyalelwe ukuba iyilungise kwangexesha.
8. Nika ingqalelo kwi-backfilling kunye nokunyanzeliswa kwekhonkrithi kwindawo engezantsi yebhanti yobhedu, kwaye wamkele ngokufanelekileyo ukufakwa kwe-oblique kunye ne-horizontal vibration.
