Ntxiv nrog rau nws qhov siab hardness, lub zog thiab corrosion kuj, beryllium bronze muaj cov yam ntxwv hauv qab no thaum siv los ua cov khoom hnav-resistant:

Ib zaj duab xis tsuas yog tsim los ntawm oxides yog tsim nyob rau saum npoo ntawm beryllium tooj liab, uas muaj zog adhesion, autogenous thiab muaj zog yam ntxwv.Muaj peev xwm muab ib nrab lubrication, txo kev sib txhuam, txo hnav thiab tshem tawm kev sib txhuam puas.

Qhov zoo thermal conductivity ntawm beryllium bronze dissipates lub tshav kub generated los ntawm kev sib hloov ntawm lub rotating ncej nyob rau hauv siab load, txo lub melting ntawm ncej thiab bearing.Yog li sticking tsis tshwm sim.Piv txwv ntawm beryllium bronze casting alloys siv los ua qhov chaw:

Mine log bearings ua los ntawm domestic beryllium bronze, siab ntsuas twj tso kua mis bearings thiab lwm yam hnyav loads thiab high pressures tau tiav zoo heev.Nws tau dav siv nyob rau hauv ntau yam bearings thiab bushings ntawm aircraft txawv teb chaws, thiab nws cov kev pab cuam lub neej yuav ua tau ze li ntawm peb lub sij hawm ntev tshaj li cov nickel bronze.Piv txwv li, nws yog siv rau zawv zawg bearings ntawm tub rog thauj thav duab, bearings rau rotating clutches, thiab bearings rau pej xeem aviation Boeing 707, 727, 737, 747, F14, thiab F15 fighter dav hlau;American Airlines siv beryllium bronze alloy bearings los hloov tus thawj Al bearing /FONT>Ni bronze cam khwb cia bearing, lub neej kev pab cuam yog nce los ntawm thawj 8000 teev mus rau 20000 teev.

Lub beryllium bronze puab lub tes tsho ntawm cov pwm ntawm kab rov tav nruam casting tshuab muaj kev pab cuam lub neej ntawm peb lub sij hawm ntawm phosphorus deoxidized tooj liab;Lub neej kev pabcuam ntawm beryllium bronze txhaj lub taub hau (punch) ntawm lub tshuab tuag casting yog ze li ntawm 20 npaug ntev dua li ntawm cov hlau cam khwb cia.Nws tau siv dav hauv tsev thiab txawv teb chaws.

Rau blast furnace tuyere.Ib qho kev sim tuyere tsim los ntawm United States Steel Corporation, cov dej-txias beryllium tooj liab nozzle txuas mus rau hauv lub cub tawg, cua kub kub hauv lub nozzle yog 9800c, thiab steel tuyere ua hauj lwm rau qhov nruab nrab ntawm 70 hnub, thaum lub beryllium bronze tuyere. tuaj yeem ncav cuag 268 hnub.3-2-4 yog siv nyob rau hauv drilling machinery, qhov cub mining machinery, tsheb, diesel cav thiab lwm yam machinery industries.Piv txwv li, lub tes tsho ncej ntawm lub ntsiab drilling rig ntawm US 3 "ntsis yog ua los ntawm beryllium bronze, uas triples lub pob zeb drilling efficiency.

Beryllium bronze yog siv rau ntawm lub tshuab luam ntawv ceev ceev uas muaj peev xwm luam tawm 7,200 lo lus ib feeb, nce cov duab los ntawm thawj 2 lab lo lus mus rau 10 lab lo lus.

Siv los ua cov khoom siv tiv thaiv corrosion

Beryllium bronze alloys tiv taus abrasion nrog rau deoxidized tooj liab tsis muaj kev ntxhov siab corrosion tawg lossis argon embrittlement.Nws muaj qhov zoo corrosion qaug zog hauv huab cua thiab ntsev tsuag;nyob rau hauv acidic nruab nrab (tshwj tsis yog argon fluoric acid), corrosion kuj ntawm phosphor bronze yog ob zaug siab;nyob rau hauv dej hiav txwv, nws tsis yooj yim rau pitting corrosion, roj ntsha plugs los yog tawg, thiab lwm yam lub cev muaj zog thiab lub repeater, thiab universal plhaub ntawm lub cev muaj zog thiab lub repeater.Hauv tsev, beryllium bronze tau siv los ua cov khoom siv acid-resistant rau hydrometallurgical sulfuric acid nruab nrab, xws li S-hom stirring ncej ntawm kneader, twj tso kua mis casing ntawm acid-resistant twj, impeller, ncej, thiab lwm yam.

siv los ua cov khoom siv electrode

High conductivity beryllium bronze casting alloy muaj cov khoom siv hluav taws xob zoo, thermal conductivity, siab hardness, hnav tsis kam, tawg tsis kam, thiab cov khoom tawg tuaj yeem tswj tau txawm tias kub dua.Cov khoom siv hlau no yog siv los ua cov khoom siv hluav taws xob ntsig txog ntawm lub tshuab fusion welding, thiab tuaj yeem tau txais qhov cuam tshuam ntawm kev poob qis thiab qis tag nrho cov nqi vuam.Nws yog cov khoom siv zoo tshaj plaws rau vuam.Lub koom haum American Welding Society qhia txog beryllium bronze raws li cov khoom siv electrode.

raws li cov cuab yeej kev nyab xeeb

Beryllium bronze alloys tsis paj thaum cuam tshuam los yog rubbed.Thiab muaj cov khoom tsis sib nqus, hnav-tiv taus, corrosion-resistant zog.Nws yog qhov tsim nyog rau kev tsim cov cuab yeej kev nyab xeeb uas siv rau hauv kev tawg, tawg, muaj zog sib nqus thiab corrosive zaus.BeA-20C alloy tau raug cuam tshuam rau lub zog ntawm 561IJ hauv 30% oxygen lossis 6.5-10% methane pa-oxygen, thiab nws raug cuam tshuam 20 zaug yam tsis muaj txim taws thiab combustion.Lub chaw ua haujlwm kev nyab xeeb ntawm Tebchaws Meskas, Nyij Pooj thiab lwm lub tebchaws tau tsim cov kev cai lij choj uas beryllium tooj liab cov cuab yeej kev nyab xeeb yuav tsum tau siv rau hauv qhov chaw txaus ntshai uas yuav tsum muaj kev tiv thaiv hluav taws thiab tswj kev kub ntxhov.Kev siv beryllium tooj liab cov cuab yeej kev nyab xeeb yog kev tiv thaiv kev tiv thaiv kom tsis txhob muaj hluav taws kub thiab tawg tshwm sim nyob rau hauv cov chaw khaws khoom tawg thiab qhov chaw siv cov khoom txaus ntshai no.Lub ntsiab ntawm daim ntawv thov yog: roj av refining thiab petrochemical kev lag luam, qhov cub mine, roj teb, natural gas chemical kev lag luam, gunpowder kev lag luam, tshuaj fiber kev lag luam, pleev xim kev lag luam, chiv kev lag luam, thiab ntau yam tshuaj industries.Petroleum ships thiab liquefied petroleum gas tsheb, dav hlau, warehouses cuam tshuam nrog cov khoom flammable thiab explosives, electrolysis rhiav, kev sib txuas lus tshuab los ua ke rhiav, qhov chaw uas yuav tsum tau cov cuab yeej tsis xeb, hnav-resistant thiab anti-magnetic, thiab lwm yam.

Txawm hais tias beryllium thiab nws cov alloys thiab beryllium oxide tau tsim ua ntej, lawv cov kev siv feem ntau yog siv rau hauv cov cuab yeej siv hluav taws xob, riam phom, chaw tsim khoom, lub qhov rais rays, optical systems, instrumentation, thiab khoom siv hauv tsev.Tej zaum nws yuav hais tau tias kev nce qib ntawm cov thev naus laus zis thaum ntxov tau txhawb kev txhim kho thiab siv cov beryllium thiab nws cov alloys, thiab tom qab ntawd maj mam nthuav dav mus rau cov khoom siv hauv tsev, tsheb, kev sib txuas lus thiab lwm yam kev lag luam.Be-Cu alloys muaj ntau yam kev siv.

Lub toxicity, brittleness, tus nqi siab thiab lwm yam ntawm beryllium txwv kev siv thiab kev loj hlob ntawm beryllium cov ntaub ntawv.Txawm li cas los xij, cov ntaub ntawv beryllium tseem yuav qhia lawv cov txuj ci hauv cov xwm txheej uas lwm yam khoom siv tsis tuaj yeem hloov tau.

Daim ntawv no qhia txog cov khoom thiab kev siv ntawm beryllium thiab nws cov alloys, beryllium oxide, thiab beryllium composites txij li thaum nrhiav tau ntawm beryllium.Kev thov ntawm beryllium ua rau muaj txiaj ntsig tshiab.
