I-High Precision Custom Brass Tube Kanye Nenduku Eqinile
Isilinganiso sobumsulwa
Ukuhlanzeka kwethusi kungalinganiswa kusetshenziswa isimiso se-Archimedes, lapho umthamo nesisindo sesampula kukalwa, bese iphesenti lethusi eliqukethwe yethusi lingabalwa ngokusekelwe kubuningi bethusi kanye nokuminyana kwe-zinc.
Ithusi elivamile
Kuyi-alloy yethusi ne-zinc.
Uma okuqukethwe kwe-zinc kungaphansi kwama-35%, i-zinc ingancibilika ngethusi ukuze kwakhiwe i-alpha yesigaba esisodwa, ebizwa ngokuthi i-single-phase brass, i-plasticity enhle, efanelekile ukucutshungulwa kokucindezela okushisayo nokubandayo.
Uma okuqukethwe kwe-zinc kungu-36% ~ 46%, kune-α isigaba esisodwa kanye nesisombululo esiqinile esingu-β esisekelwe ethusi ne-zinc, esibizwa nge-biphasic brass, isigaba se-β senza i-plasticity yethusi yehle futhi amandla aqinile akhuphuke, afanele kuphela ukucubungula ingcindezi eshisayo.
Uma siqhubeka nokwandisa ingxenye enkulu ye-zinc, amandla e-tensile ayancipha futhi akanalo inani lokusetshenziswa.
Ikhodi iboniswa ngokuthi "H + inombolo", H isho ithusi, futhi inombolo isho ingxenye enkulu yethusi.
Isibonelo, i-H68 isho ithusi eliqukethe u-68% wethusi no-32% we-zinc, futhi ithusi elibunjiwe landulelwa igama elithi "Z", njenge-ZH62.
Isibonelo, i-ZCuZnzn38 isho ithusi eliphonsa nge-38% zinc kanye nenani elisele lethusi.
I-H90, i-H80 ingeyethusi lesigaba esisodwa, okuphuzi okusagolide.
I-H59 i-duplex brass, esetshenziswa kakhulu ezingxenyeni zesakhiwo sezinto zikagesi, njengamabhawudi, amantongomane, amawasha, iziphethu nokunye.
Ngokuvamile, ithusi lesigaba esisodwa lisetshenziselwa ukucubungula ukuguqulwa okubandayo kanye nethusi eliphindwe kabili lisetshenziselwa ukucubungula ukushisa okushisayo.
Ithusi elikhethekile
I-multi-alloy eyakhiwe ngokungeza ezinye izakhi ze-alloying yethusi evamile ibizwa ngokuthi ithusi elikhethekile.Izakhi ezivame ukungezwa ziwumthofu, ithini, i-aluminium, njll., futhi ngokufanele zingabizwa ngethusi eliholayo, ithusi lethini, ithusi le-aluminium.Inhloso yokwengeza izakhi ze-alloying.Inhloso eyinhloko ukukhulisa amandla e-tensile futhi uthuthukise ukucutshungulwa.
Ikhodi: "H + uphawu lwesici esiyinhloko esingeziwe (ngaphandle kwe-zinc) + ingxenye enkulu yethusi + ingxenye enkulu yesici esiyinhloko esingeziwe + ingxenye enkulu yezinye izakhi".
Isibonelo: I-HPb59-1 ikhombisa ukuthi ingxenye enkulu yethusi ingu-59%, ingxenye enkulu yomthofu equkethe isakhi esiyinhloko esiyisengezo ingu-1%, kanti ibhalansi ye-zinc iyithusi lomthofu.
Izici zomshini zethusi ziyahlukahluka ngokuqukethwe kwe-zinc ngenxa yamanani ahlukene e-zinc ethusi.Ku-α yethusi, kokubili u-σb kanye no-δ kukhuphuka ngokuqhubekayo njengoba okuqukethwe kwe-zinc kukhula.Ngethusi elingu-(α+β), izinga lokushisa legumbi likhuphuka ngokuqhubekayo kuze kube yilapho okuqukethwe kwe-zinc kukhushulwa cishe ku-45%.Uma okuqukethwe kwe-zinc kwanda ngokuqhubekayo, amandla ancipha kakhulu ngenxa yokubonakala kwe-brittle r-phase (Cu5Zn8 isixazululo esiqinile esisekelwe ku-compound) enhlanganweni ye-alloy.(I-plasticity yegumbi le-(α+β) yethusi ihlale yehla ngokunyuka kokuqukethwe kwe-zinc Ngakho-ke, ama-alloys e-copper-zinc ane-zinc content engaphezu kuka-45% ayinalo inani elisebenzayo.
Ithusi elivamile lisetshenziswa ezinhlobonhlobo zezinhlelo zokusebenza njengamabhande ethangi lamanzi, amapayipi amanzi kanye nokukhipha amanzi, izindondo, amapayipi kathayela, amapayipi ezinyoka, amapayipi okujiya, amagobolondo kanye nemikhiqizo ehlukahlukene eyinkimbinkimbi yokubhoboza, i-hardware encane, njll. okuqukethwe kwe-zinc kusuka ku-H63 kuya ku-H59, angakwazi ukumelana kahle nokucubungula kwesimo esishisayo, futhi asetshenziswa kakhulu ezingxenyeni ezihlukahlukene zemishini nezinto zikagesi, izingxenye zokugxiviza nezinsimbi zomculo.
Ukuze kuthuthukiswe ukumelana nokugqwala, amandla, ubulukhuni kanye nokusebenziseka kalula kwethusi, inani elincane (ngokuvamile li-1% ukuya ku-2%, abambalwa lifinyelela ku-3% kuya ku-4%, ambalwa kakhulu afika ku-5% kuya ku-6%) wethini, i-aluminium, i-manganese, insimbi, i-silicon, i-nickel, i-lead nezinye izakhi zengezwa ku-alloy yethusi-zinc ukuze kwakhiwe i-ternary, quaternary, noma ngisho ne-alloy element emihlanu, okuyithusi eliyinkimbinkimbi, eyaziwa nangokuthi ithusi elikhethekile.
I-Brass inokumelana okuqinile kokugqoka, ithusi livame ukusetshenziswa ekwenzeni ama-valve, amapayipi amanzi, isimo somoya sangaphakathi nangaphandle amapayipi okuxhuma umshini nama-radiator, njll.
Ithusi eliholayo
Umthofu cishe awuncibiliki ethusi futhi usatshalaliswa emingceleni yezinhlamvu ngendlela yenqwaba yamahhala.Kunezinhlobo ezimbili zethusi lomthofu ngokwenhlangano yazo: α kanye (α+β).I-α lead brass ingakhubazeka ngokubanda noma ikhishwe ngaphandle ngenxa yomphumela oyingozi womthofu kanye nepulasitiki ephansi emazingeni okushisa aphezulu.(α+β) ithusi eliholayo linepulasitiki elihle ezingeni lokushisa eliphezulu futhi lingakhiwa.
Ithusi likathayela
Ukwengezwa kwe-tin ethusi kungathuthukisa kakhulu ukumelana nokushisa kwe-alloy, ikakhulukazi ukuthuthukisa ikhono lokumelana nokugqwala kwamanzi olwandle, ngakho-ke ithusi le-tin linegama elithi "ithusi lasolwandle".
Ithini lingancibilika libe yisixazululo esiqinile esisekelwe ethusi, umphumela wokuqinisa isisombululo.Kodwa-ke, ngokwanda kokuqukethwe kwe-tin, ingxubevange izovela i-brittle r-phase (inhlanganisela ye-CuZnSn), engahambisani nokuguqulwa kwepulasitiki ye-alloy, ngakho okuqukethwe kwe-tin yethusi ngokuvamile ku-0.5% kuya 1.5%.
Ama-tin brasses asetshenziswa kakhulu yi-HSn70-1, HSn62-1, HSn60-1, njll. Owokuqala yi-alpha alloy ene-plasticity ephezulu futhi ingacutshungulwa ngokucindezela okubandayo noma okushisayo.Amamaki amabili okugcina ane (α+β) inhlangano yezigaba ezimbili, futhi ngokuvamile avela inani elincane le-r-phase, i-plasticity yegumbi lokushisa ayiphezulu, futhi ingakhubazeka kuphela esimweni esishisayo.
Ithusi leManganese
IManganese inokunyibilika okukhulu kwethusi eliqinile.Engeza i-1% kuya ku-4% ye-manganese yethusi, ingathuthukisa kakhulu amandla nokumelana nokugqwala kwe-alloy, ngaphandle kokunciphisa ipulasitiki yayo.
I-Manganese yethusi inenhlangano (α+β), evame ukusetshenziswa yi-HMn58-2, futhi ukusebenza kokucubungula ingcindezi esimweni esibandayo nesishisayo kuhle impela.
Ithusi elinensimbi
Ethusini lensimbi, insimbi igxuma njengezinhlayiya zesigaba esicebile ngensimbi, icwenga okusanhlamvu njengama-nuclei, futhi ivimbele ukukhula okusanhlamvu okwenziwe kabusha, ngaleyo ndlela ithuthukise izakhiwo zemishini futhi icubungule izakhiwo ze-alloy.Okuqukethwe kwe-iron ku-ferrobrass kuvame ukuba ngaphansi kuka-1.5%, futhi inhlangano yayo ingu-(α+β), inamandla amakhulu nokuqina, ipulasitiki enhle ekushiseni okuphezulu, futhi ikhubazekile esimweni esibandayo.Ibanga elisetshenziswa kakhulu yi-Hfe59-1-1.
Ithusi le-nickel
I-nickel nethusi kungakha isisombululo esiqinile esiqhubekayo, sandise kakhulu isifunda sesigaba se-alpha.Ukwengezwa kwe-nickel yethusi kungathuthukisa kakhulu ukumelana nokugqwala kwethusi emkhathini nasemanzini olwandle.I-Nickel iphinde ikhuphule izinga lokushisa le-recrystallization yethusi futhi ikhuthaze ukwakheka kwezinhlamvu ezinhle.
I-HNi65-5 nickel brass inenhlangano ye-alpha yesigaba esisodwa, ene-plasticity enhle ekamelweni lokushisa, nayo ingakhubazeka esimweni esishisayo, kodwa okuqukethwe kokungcola komthofu kufanele kulawulwe ngokuqinile, ngaphandle kwalokho kuzowohloka kakhulu izakhiwo zokucubungula ezishisayo. ingxubevange.
Izinga lokushisa lokucubungula ukushisa 750～830℃;izinga lokushisa le-anneal 520℃ 650℃;izinga lokushisa eliphansi le-annealing 260～270℃ ukuze kuqedwe ukucindezeleka kwangaphakathi.
I-Environmental Brass C26000 C2600 Ipulasitiki enhle kakhulu, amandla aphezulu, ukusebenza kahle, ukushisela, ukumelana nokugqwala okuhle, ukushintshanisa ukushisa, amashubhu okwenza iphepha, imishini, izingxenye ze-elekthronikhi.
Ukucaciswa (mm): Ukucaciswa: ukujiya: 0.01-2.0mm, ububanzi: 2-600mm.
Ukuqina: O, 1/2H, 3/4H, H, EH, SH, njll.
Amazinga asebenzayo: GB, JISH, DIN, ASTM, EN.
Izici: ukusebenza okuhle kakhulu kokusika, kulungele i-lathe ezenzakalelayo, i-CNC lathe processing yezingxenye ezinembile kakhulu.
