Brass ibhinari alloy inoumbwa nemhangura uye zinc iyo yave ichigadzirwa kwemireniyamu uye inokosheswa nekuda kwekushanda kwayo, kuoma, kusaita ngura, uye chitarisiko chinoyevedza.
Jindalai (Shandong) Steel Group Co., Ltd. inopa zvigadzirwa zvakasiyana-siyana zvendarira muhukuru uye huwandu kuti zvizadzise zvinodiwa zvechero chirongwa.

2. Hunhu
Izvo zvinhu chaizvo zvendarira zvakasiyana zvinoenderana nekuumbwa kwemhangura alloy, kunyanya chiyero chemhangura-zinc. Muzhinji, zvisinei, mabhurashi ese anokosheswa nekuda kwemachinability yavo kana kuti nyore iyo simbi inogona kuumbwa kuita inodiwa maumbirwo uye mafomu ichichengeta yakakwira simba.
Kunyange paine misiyano pakati pemabhurasi ane yakakwira uye yakaderera zinc zviri mukati, mabhurasi ese anoonekwa seanogona uye ductile (yakaderera zinc brasses zvakanyanya kudaro). Nekuda kwekudzika kwayo kunyungudika, ndarira inogonawo kukandwa zviri nyore. Nekudaro, yekukanda maapplication, yakakwira zinc yemukati inowanzo kufarirwa.
Mabhurasi ane yakaderera zinc zvemukati anogona kutonhora kushanda nyore, welded uye brazed. Yakakwirira mhangura yemukati inobvumirawo simbi kuti igadzire inodzivirira oxide layer (patina) pamusoro payo inochengetedza kubva kune imwe corrosion, chinhu chakakosha mumashandisirwo anoburitsa simbi kune mwando uye mamiriro ekunze.
Simbi ine zvese zvakanaka kupisa uye magetsi conductivity (mabatiro ayo emagetsi anogona kubva pa23% kusvika 44% yemhangura yakachena), uye inopfeka uye spark inoshingirira. Kufanana nemhangura, iyo bacteriostatic zvimiro zvakakonzera kushandiswa kwayo muzvigadziriso zvekugezera uye nzvimbo dzehutano.
Brass inoonekwa seyakaderera friction uye isiri-magnetic alloy, nepo acoustic zvimiro zvakonzera kushandiswa kwayo mune akawanda 'brass band' zviridzwa zvemimhanzi. Vanyori nevagadziri vezvivakwa vanokoshesa kunaka kwesimbi, sezvo ichikwanisa kugadzirwa mumhando dzakasiyana-siyana, kubva kune yakatsvuka yakadzika kusvika kune yegoridhe yero.
3. Zvikumbiro
Zvivakwa zvakakosha zveBrass uye kureruka kwekugadzira kwaita kuti ive imwe yeanonyanya kushandiswa alloys. Kunyora runyoro rwakakwana rwezvose brass'applications ringava basa rakakura, asi kuti uwane pfungwa yemaindasitiri uye mhando dzezvigadzirwa umo ndarira inowanikwa tinogona kuisa mumapoka uye muchidimbu mamwe ekupedzisira-kushandiswa zvichienderana negiredhi rendarira rinoshandiswa:
● Yemahara yendarira yekucheka (semuenzaniso C38500 kana 60/40 ndarira):
● Nuts, mabhaudhi, zvikamu zvine thread
● Zviteshi
● Jets
● Mapombi
● Majekiseni
4. Nhoroondo
Copper-zinc alloys akagadzirwa kare muzana ramakore rechi 5 BC muChina uye aishandiswa zvakanyanya pakati peAsia nezana ramakore rechipiri nerechitatu BC. Izvi zvidimbu zvesimbi zvekushongedza, zvisinei, zvinogona kutaurwa zvakanyanya se "natural alloys," sezvo pasina humbowo hwekuti vagadziri vavo vakanyatso sanganisa mhangura uye zinc. Pane kudaro, zvingangoita kuti maalloys akanyungudutswa kubva kune zinc-rich copper ores, achigadzira simbi isina kuchena sendarira.
Zvinyorwa zvechiGiriki nevechiRoma zvinoratidza kuti kugadzirwa nemaune kwema alloys akafanana nendarira yemazuva ano, vachishandisa copperand zinc oxide-rich ore inozivikanwa se calamine, yakaitika kumakore ekuma1st century BC. Calamine brass yakagadzirwa pachishandiswa simende process, iyo mhangura yakanyungudutswa mu. crucible with ground smithsonite (kana calamine) ore.
Pakupisa kwepamusoro, zinc iripo muore yakadai inoshanduka kuita mhute uye ichipinda mumhangura, zvoita kuti ibudise ndarira yakachena ine 17-30% zinc content. Iyi nzira yekugadzirwa kwendarira yakashandiswa kwemakore anoda kusvika 2000 kusvika pakutanga kwezana remakore rechi19. Pasina nguva vaRoma vaziva nzira yokugadzira ndarira, alloy yacho yakanga yava kushandiswa kuita mari munzvimbo dzeTurkey yemazuva ano. Izvi zvakabva zvapararira muUmambo hweRoma hwose.
5. Mhando
'Brass' ishoko rekare rinoreva huwandu hwakawanda hwemhangura-zinc alloys. Muchokwadi, kune anopfuura makumi matanhatu akasiyana marudzi endarira anotsanangurwa neEN (European Norm) Mayero. Aya ma alloys anogona kuve neakasiyana siyana enziyo zvichienderana nemidziyo inodiwa kune imwe application.
6. Kugadzirwa
Brass inowanzogadzirwa kubva kumhangura yemhangura uye zinc ingots. Chikafu chemhangura chinosarudzwa zvichienderana nekusachena kwayo, sezvimwe zvinhu zvekuwedzera zvinodiwa kuitira kuti ibudise giredhi chaiyo yendarira inodiwa.
Nekuda kwekuti zinc inotanga kufashaira uye kunyunguduka pa1665°F (907°C), pasi pekunyunguduka kwemhangura 1981° F (1083°C), mhangura inofanira kutanga yanyungudutswa. Kana yanyungudutswa, zinc inowedzerwa pachiyero chakakodzera giredhi rendarira riri kugadzirwa. Nepo kumwe kubvumidzwa kuchiri kuitirwa zinc kurasikirwa nevaporization.
Panguva ino, chero mamwe masimbi ekuwedzera, akadai se lead, aluminium, silicon kana arsenic, anowedzerwa kumusanganiswa kugadzira iyo inodiwa alloy. Kana alloy yakanyungudutswa yagadzirwa, inodururwa muforoma iyo inoomesa kuita slabs hombe kana mabhiriti. Mabhiridha - kazhinji ealpha-beta brass - anogona kugadziriswa zvakananga kuita waya, pombi, uye machubhu kuburikidza nekupisa extrusion, iyo inosanganisira kusunda simbi inopisa kuburikidza nefa, kana kupisa kunopisa.
Kana isina kubudiswa kana kuumbwa, mabheti anobva adzoserwa uye anodyiswa kuburikidza nesimbi rollers (maitiro anozivikanwa sehot rolling). Mhedzisiro yacho ma slabs ane ukobvu husingasviki hafu ye inch (<13mm). Mushure mekutonhodzwa, ndarira inozodyiswa kuburikidza nemuchina wekugaya, kana scalper, iyo inocheka danda rakatetepa kubva musimbi kuitira kubvisa pamusoro pekukanda kukanganisa uye oxide.
Pasi pemhepo yegasi kudzivirira oxidization, alloy inodziyirwa uye inokungurutswa zvakare, maitiro anozivikanwa seannealing isati yakungurutswa zvakare panotonhorera (inotonhora rolling) kusvika kumapepa anosvika 0.1" (2.5mm) gobvu. chimiro chezviyo chemukati chendarira, chinokonzera simbi yakasimba uye yakaoma.
Pakupedzisira, mapepa anochekwa uye kuchekwa kuti abudise upamhi nehurefu hunodiwa. Mashizha ese, akaumbwa, akaumbwa, uye akawedzera ndarira zvinhu zvinopihwa kemikari yekugezesa, kazhinji, imwe yakagadzirwa nehydrochloric uye sulfuric acid, kubvisa dema mhangura oxide scale uye kusvibisa.
Jindalai inventory brasshe sheets uye makoiri muhukobvu kubva pa0.05 kusvika 50mm, uye mune annealed, quarter hard, half hard, uye yakazara kushatirwa. Dzimwe hasha uye alloys zviripo zvakare. Tumira kubvunza kwako uye isu tichafara kukubvunza iwe nehunyanzvi.
