Funda Ngezakhiwo Nokusetshenziswa Kwensimbi Yethusi

I-Jindalai (Shandong) Steel Group Co., Ltd. inikeza imikhiqizo ehlukahlukene yethusi ngobukhulu nangobuningi ukuze kuhlangatshezwane nezidingo zanoma yimuphi umsebenzi.
1. Izakhiwo

● Okuqukethwe: Ithusi kanye neZinc
● Ubuningi: 8.3-8.7 g/cm3
● Indawo Yokuncibilika: 1652-1724 °F (900-940 °C)

2. Izici
Izakhiwo eziqondile zethusi ezahlukene zincike ekwakhiweni kwe-alloy yethusi, ikakhulukazi isilinganiso sethusi-zinc. Ngokuvamile, nokho, zonke zethusi ziyaziswa ngobuchwepheshe bazo noma ukulula kwensimbi ukwakheka kwayo ibe yizimo nezinhlobo ezifiselekayo ngenkathi igcina amandla aphezulu.

Nakuba kukhona umehluko phakathi kwama-brasses anokuqukethwe okuphezulu nokuphansi kwe-zinc, wonke ama-brasses abhekwa njengasebenzisekayo futhi athambile (ama-brasses aphansi kakhulu kune-zinc). Ngenxa yezinga layo eliphansi lokuncibilika, i-brass nayo ingaphonswa kalula. Kodwa-ke, ekusetshenzisweni kokuphonswa, okuqukethwe okuphezulu kwe-zinc kuvame ukukhethwa.

Ama-brass anokuqukethwe okuphansi kwe-zinc angafakwa kalula emakhazeni, ashiselwe futhi afakwe i-brass. Ukuqukethwe okuphezulu kwethusi kuvumela nensimbi ukuthi yakhe ungqimba lwe-oxide oluvikelayo (patina) ebusweni bayo oluvikela ukugqwala okuqhubekayo, okuyimpahla ebalulekile ekusetshenzisweni okuveza insimbi emswakama nasekugugeni.

Insimbi inokushisa okuhle kanye nokuqhuba kukagesi (ukuqhuba kwayo kukagesi kungaba kusuka ku-23% kuya ku-44% kunokwethusi omsulwa), futhi ayigugi futhi ayimelani nenhlansi. Njengethusi, izakhiwo zayo ezibangelwa amagciwane ziye zaholela ekusetshenzisweni kwayo ezindlini zangasese nasezikhungweni zezempilo.

Ithusi libhekwa njengengxubevange ephansi yokungqubuzana kanye ne-non-magnetic, kuyilapho izakhiwo zalo ze-acoustic ziholele ekusetshenzisweni kwalo eziculweni zomculo eziningi 'zebhendi yethusi'. Abaculi nabakhi bezakhiwo bayazazisa izakhiwo zobuhle bensimbi, njengoba ingakhiqizwa ngemibala ehlukahlukene, kusukela kubomvu ojulile kuya kuphuzi wegolide.

3. Izicelo
Izakhiwo ze-brass eziyigugu kanye nokulula kokukhiqizwa kwazo kwenze kwaba ngenye yezinhlobo ze-alloy ezisetshenziswa kakhulu. Ukuhlanganisa uhlu oluphelele lwazo zonke izinhlelo zokusebenza ze-brass kungaba umsebenzi omkhulu, kodwa ukuze sithole umbono wezimboni kanye nezinhlobo zemikhiqizo lapho i-brass itholakala khona singahlukanisa futhi sifingqe ezinye izindlela zokusetshenziswa ngokusekelwe ebangeni le-brass esetshenzisiwe:
● Ithusi lokusika lamahhala (isib. ithusi elingu-C38500 noma elingu-60/40):
● Amantongomane, amabhawodi, izingxenye ezinentambo
● Amatheminali
● AmaJethi
● Amathephu
● Ama-injector

4. Umlando
Ama-alloy e-Copper-zinc akhiqizwa ekuqaleni kwekhulu lesi-5 BC eShayina futhi asetshenziswa kabanzi e-Asia ephakathi ngekhulu lesi-2 nelesi-3 BC. Nokho, lezi zingcezu zensimbi zokuhlobisa zingabizwa ngokuthi 'ama-alloy emvelo,' njengoba kungekho bufakazi bokuthi abakhiqizi bazo baxuba ithusi ne-zinc ngamabomu. Esikhundleni salokho, kungenzeka ukuthi ama-alloy ayencibilikiswa kusuka kuma-ore ethusi acebile nge-zinc, akhiqiza izinsimbi ezifana nethusi elicwengekile.

Imibhalo yamaGreki namaRoma isikisela ukuthi ukukhiqizwa ngamabomu kwama-alloy afana nethusi lanamuhla, kusetshenziswa ithusi kanye ne-ore ecebile nge-zinc oxide eyaziwa ngokuthi i-calamine, kwenzeka cishe ngekhulu loku-1 BC. Ithusi le-calamine lakhiqizwa kusetshenziswa inqubo yokufaka ukhonkolo, lapho ithusi lalincibilikiswa khona esitsheni esinomshini we-smithsonite (noma i-calamine).

Emazingeni okushisa aphezulu, i-zinc ekhona kuleyo ore iphenduka umhwamuko futhi igcwale ithusi, ngaleyo ndlela ikhiqize ithusi elimsulwa elinokuqukethwe kwe-zinc okungu-17-30%. Le ndlela yokukhiqiza ithusi yasetshenziswa cishe iminyaka engu-2000 kwaze kwaba sekuqaleni kwekhulu le-19. Ngemva nje kokuba amaRoma ethole indlela yokukhiqiza ithusi, i-alloy yayisetshenziswa ekuqoqweni kwezinhlamvu zemali ezindaweni zaseTurkey yanamuhla. Lokhu kwasakazeka ngokushesha kulo lonke uMbuso WaseRoma.

5. Izinhlobo
'Ithusi' igama elijwayelekile elibhekisela ezinhlobonhlobo eziningi ze-copper-zinc alloys. Eqinisweni, kunezinhlobo ezingaphezu kuka-60 ezahlukene zethusi ezichazwe yi-EN (European Norm) Standards. Lezi zinhlobo ze-alloys zingaba nohlu olubanzi lwezinhlobo ezahlukene kuye ngezakhiwo ezidingekayo ekusetshenzisweni okuthile.

6. Ukukhiqizwa
Ithusi livame ukukhiqizwa ngama-ingot ethusi aqoshiwe kanye ne-zinc. Ithusi eliqoshiwe likhethwa ngokusekelwe ekungcoleni kwalo, njengoba kudingeka ezinye izakhi ukuze kukhiqizwe izinga eliqondile lethusi elidingekayo.
Ngenxa yokuthi i-zinc iqala ukubila futhi iphele ngo-1665°F (907°C), ngaphansi kwephuzu lokuncibilika kwethusi ngo-1981°F (1083°C), ithusi kumele liqale lincibilike. Uma selincibilikile, i-zinc yengezwa ngesilinganiso esifanele izinga lethusi elikhiqizwayo. Nakuba kusekhona ithuba lokulahlekelwa yi-zinc ngenxa yokuhwamuka.

Kuleli qophelo, noma yiziphi ezinye izinsimbi ezengeziwe, njenge-lead, i-aluminium, i-silicon noma i-arsenic, zengezwa engxubeni ukuze kudalwe i-alloy efiselekayo. Uma i-alloy encibilikisiwe isilungile, ithululelwa ezikhumbeni lapho iqina khona ibe yizingcezu ezinkulu noma ama-billet. Ama-billet - ngokuvamile ethusi le-alpha-beta - angacutshungulwa ngqo abe yizintambo, amapayipi, namapayipi nge-extrusion eshisayo, okubandakanya ukusunduza insimbi eshisayo nge-diye, noma i-hot forging.

Uma kungakhishwa noma kungahlanganiswa, ama-billet abese eshiswa kabusha futhi afakwe ngama-roller ensimbi (inqubo eyaziwa ngokuthi ukugoqa okushisayo). Umphumela uba ama-slabs anobukhulu obungaphansi kwengxenye yesentimitha (<13mm). Ngemva kokupholisa, ithusi libe selifakwa ngomshini wokugaya, noma i-scalper, esika ungqimba oluncane ensimbini ukuze kususwe amaphutha okubumba ebusweni kanye ne-oxide.

Ngaphansi kwesimo segesi ukuvimbela i-oxidation, i-alloy iyashiswa bese iphinda igoqwe, inqubo eyaziwa ngokuthi i-annealing ngaphambi kokuba iphinde igoqwe emazingeni okushisa apholile (i-cold rolling) ibe amashidi anobukhulu obungu-0.1" (2.5mm). Inqubo yokugoqwa ebandayo iguqula isakhiwo sangaphakathi sethusi, okuholela ensimbini eqinile kakhulu neqinile. Lesi sinyathelo singaphindwa kuze kube yilapho kufinyelelwa ukujiya noma ubulukhuni obufunwayo.

Ekugcineni, amashidi ayasikwa futhi agundwe ukuze kutholakale ububanzi nobude obudingekayo. Wonke amashidi, izinto zethusi ezibunjiwe, ezibunjiwe, nezikhishwe ngethusi anikezwa ukugeza ngamakhemikhali, ngokuvamile, okwenziwe nge-hydrochloric ne-sulfuric acid, ukuze kususwe isikali se-black copper oxide kanye nokubola.

Amashidi ethusi e-Jindalai aqukethe ubuningi obusukela ku-0.05 kuya ku-50mm, kanye nama-annealed, ikota eqinile, isigamu esiqinile, kanye nama-full hard tempers. Amanye ama-tempers nama-alloys ayatholakala. Thumela umbuzo wakho futhi sizojabula ukubonisana nawe ngobuchwepheshe.
