Beryllium tooj liab tau muab faib ua siab beryllium tooj liab thiab qis beryllium tooj liab.High beryllium tooj liab hais txog beryllium tooj liab nrog cov ntsiab lus beryllium ntau dua 2.0.Beryllium tooj liab yog cov khoom siv vuam electrode rau vuam, nrog cov hluav taws xob zoo thiab thermal conductivity thiab siab hardness.Thaum vuam, cov electrode hnav tsawg dua, qhov nrawm nrawm, thiab tus nqi qis.
Beryllium Copper Production Process
Kev tsim cov txheej txheem ntawm beryllium tooj liab tau muab faib ua plaub kauj ruam: kev tsim cov beryllium-tooj ​​liab master alloy los ntawm kev txo qis carbothermal, smelting ntawm beryllium tooj liab alloy, ingot ntawm tooj liab alloy thiab zus tau tej cov beryllium tooj liab alloy phaj, sawb thiab sawb.
Kev tsim cov beryllium-tooj ​​liab master alloys los ntawm kev txo qis carbothermal hais txog kev txo qis ntawm beryllium hauv beryllium oxide nrog carbon hauv molten tooj liab, ua raws li alloying hauv tooj liab.Kev tsim khoom ntawm beryllium-tooj ​​liab master alloy los ntawm kev txo qis hauv kev lag luam yog nqa tawm hauv hluav taws xob arc rauv.Lub tshuab hluav taws xob arc rauv yog muab tso rau hauv lub thawv kaw.Tus neeg tsav tsheb hnav lub npog ntsej muag roj.% ntawm carbon hmoov yog tov rau hauv lub pob zeb thiab hauv av, thiab tom qab ntawd ib txheej ntawm tooj liab, txheej ntawm beryllium oxide thiab carbon hmoov sib tov yog loaded rau hauv hluav taws xob arc rauv nyob rau hauv batches, energized thiab melted.Thaum txias rau 950 degrees Celsius - 1000 degrees Celsius, alloy lub npe beryllium carbide, carbon, thiab residual hmoov ntab, slag, thiab ces muab pov rau hauv 2.25 kg los yog 5 kg ingots ntawm 950 degrees Celsius.
Tus nqi siv nyob rau hauv smelting beryllium tooj liab alloy muaj xws li cov hlau tshiab, seem, theem nrab remelting nqi thiab master alloy.
Beryllium feem ntau siv beryllium-tooj ​​liab master alloy (muaj beryllium 4%);nickel qee zaum siv cov hlau tshiab, uas yog, electrolytic npib tsib xee, tab sis nws yog qhov zoo dua los siv cov nickel-tooj ​​liab master alloy (muaj 20% nickel);cobalt siv cobalt-copper master alloy (Cobalt 5.5%), thiab qee qhov ncaj qha siv cobalt ntshiab;titanium ntxiv los ntawm titanium-tooj ​​liab master alloy (muaj 15% titanium, thiab qee qhov kuj muaj 27.4% titanium), thiab qee qhov ncaj qha ntxiv daim txhuam cev titanium;magnesium yog magnesium - Copper master alloy (muaj 35.7% magnesium) tau ntxiv.
Cov chips (milling chips, txiav chips, thiab lwm yam) thiab cov ces kaum me me uas tau tsim thaum lub sijhawm ua haujlwm feem ntau raug muab pov rau hauv ingots tom qab remelting theem nrab raws li tus nqi smelting;Ntxiv nrog rau cov khoom siv rov ua dua tshiab, thaum batching Nws kuj yog ib qho ntxiv rau qee qhov pov tseg pov tseg thiab ua cov khoom pov tseg ncaj qha rau lub qhov cub.
Lub ingot ntawm beryllium tooj liab alloy yog muab faib ua non-vacuum ingot thiab nqus ingot.Cov txheej txheem uas tsis yog lub tshuab nqus tsev casting tam sim no siv nyob rau hauv kev xyaum ntawm beryllium tooj liab alloy ntau lawm xws li inclined hlau pwm ingot casting, flowless ingot casting, semi-nruab nrab ingot casting thiab nruam ingot casting.Thawj ob txoj kev tsuas yog siv hauv cov chaw tsim khoom nrog cov nplais me me.
Cov kws tshaj lij tau hais tias txhawm rau kom tau txais beryllium-tooj ​​liab alloy ingots nrog cov ntsiab lus roj tsawg, kev sib cais me me, kev suav nrog tsawg, thiab cov qauv siv lead ua zoo sib xws, txoj hauv kev zoo tshaj plaws yog lub tshuab nqus tsev tom qab nqus smelting.Nqus ingot casting muaj qhov cuam tshuam tseem ceeb ntawm kev ua kom cov ntsiab lus ntawm cov khoom yooj yim oxidizable xws li beryllium thiab titanium.Thaum tsim nyog, cov roj inert tuaj yeem raug qhia los tiv thaiv cov txheej txheem ingot casting.
Lub ntsiab lus ntawm beryllium tooj liab kev kho cua sov: kev kho cua sov ntawm beryllium bronze Kev kho cua sov ntawm beryllium bronze tuaj yeem muab faib ua kev kho annealing, kev kho kev daws teeb meem thiab kev laus kev kho mob tom qab kev daws teeb meem.
Lub beryllium tooj liab retreat (rov qab) kev kho mob yog muab faib ua: (1) Intermediate softening annealing, uas yuav siv tau rau cov softening txheej txheem nyob rau hauv nruab nrab ntawm kev ua.(2) Stabilized tempering yog siv los tshem tawm cov machining kev nyuaj siab generated thaum lub sij hawm precision springs thiab calibration, thiab stabilize lub sab nraud qhov ntev.(3) Kev ntxhov siab rau kev ntxhov siab yog siv los tshem tawm cov kev ntxhov siab ntawm kev ua haujlwm thaum lub sij hawm machining thiab calibration.
