Ultra-siab zog graphite electrodes tau siv dav hauv cov hauv qab no:
1.Graphite pwm rau nruam thiab ib nrab-nruam casting ntawm cov hlau tsis-ferrous
Nyob rau hauv xyoo tas los no, cov txheej txheem ntau lawm xws li ncaj qha mus txuas ntxiv (lossis ib nrab txuas ntxiv) kev tsim khoom ntawm cov tuav lossis cov raj los ntawm lub xeev molten hlau tau txhawb nqa ob qho tib si hauv tsev thiab txawv teb chaws. Txoj kev no tau pib siv rau hauv Suav teb hauv cov khoom xws li tooj liab, tooj liab alloys, aluminium thiab aluminium alloys. Artificial graphite yog suav tias yog cov khoom tsim nyog tshaj plaws rau kev nruam lossis semi-nruab nrab casting pwm ntawm cov hlau tsis muaj hlau. Kev xyaum ntau lawm tau ua pov thawj tias vim yog kev siv cov graphite pwm, uas muaj cov thermal conductivity zoo (thermal conductivity txiav txim siab lub zog ceev ntawm cov hlau los yog alloys) thiab kev ua haujlwm zoo ntawm cov pwm, tsis yog tsuas yog qhov nrawm nrawm, tab sis kuj vim qhov loj ntawm cov khoom siv yog qhov tseeb, qhov saum npoo yog du, thiab cov qauv crystalline zoo ib yam, cov txheej txheem ua haujlwm tom ntej tuaj yeem ua ncaj qha. Qhov no tsis tsuas yog ua kom cov txiaj ntsig zoo ntawm cov khoom tiav thiab txo qis cov khoom pov tseg, tab sis kuj tseem txhim kho cov khoom zoo.
Muaj ob hom kev nruam casting: ntsug nruam casting thiab kab rov tav nruam casting.
2. Pwm rau siab casting
Artificial graphite cov ntaub ntawv tau ntse siv nyob rau hauv lub siab casting ntawm non-ferrous hlau. Piv txwv li, zinc alloy thiab tooj liab alloy castings ua los ntawm cov pwm molds ua los ntawm cov khoom siv graphite tau siv rau hauv tsheb thiab lwm yam.
3. Kub nias tuag
Artificial graphite kub nias tuag muaj cov yam ntxwv hauv qab no thaum siv lub siab sintering ntawm cemented carbide:
Ua ntej, yog tias qhov ntsuas kub tau nce mus rau 1350-1450 degrees, qhov xav tau ntawm chav tsev siab tuaj yeem txo mus rau 67-100 kilograms quab yuam ib square centimeter (uas yog, ib feem kaum ntawm qhov txias nias). Qhov thib ob, lub zog thiab cua sov yog nqa tawm nyob rau hauv tib txoj kev, thiab lub cev ntom ntom sintered tuaj yeem tau txais tom qab lub sijhawm luv luv ntawm sintering.
4. Pwm rau iav txoj kev
Vim muaj cov tshuaj lom neeg ruaj khov ntawm cov khoom siv graphite, lawv tsis kam ntub los ntawm cov iav molten, thiab qhov tseeb tias lawv tsis hloov cov iav muaj pes tsawg leeg, nrog rau lawv cov thermal shock kuj zoo thiab qhov me me hloov pauv nrog qhov kub thiab txias, lawv tau dhau los ua cov khoom siv pwm tseem ceeb hauv iav tsim hauv xyoo tas los no. Lawv tuaj yeem siv los ua pwm rau iav raj, lub luj tshib, funnels, thiab ntau yam tshwj xeeb zoo li lub khob iav.
5. Sintering tuag thiab lwm yam
Ua kom zoo dua ntawm cov thermal deformation me me ntawm cov khoom siv graphite, sintering pwm thiab brackets rau transistors tuaj yeem tsim. Nws yog tam sim no siv dav thiab tau dhau los ua cov khoom siv tsis tseem ceeb rau kev txhim kho kev lag luam semiconductor. Tsis tas li ntawd, graphite pwm kuj tseem siv rau hauv cov pwm pwm, pwm pwm rau ntau yam hlau tsis-ferrous, pwm rau cam khwb cia hlau, pwm rau cov hlau tsis muaj cua sov (xws li titanium, zirconium, molybdenum, thiab lwm yam), thiab pwm rau aluminothermic vuam pwm rau vuam ntsia, thiab lwm yam.
6. Graphite pwm rau centrifugal casting
Pwm graphite tau ua tiav hauv centrifugal casting. Tebchaws Asmeskas tau txais cov khoom tsim graphite pwm nrog phab ntsa tuab ntawm ntau dua 25 millimeters rau centrifugal casting ntawm bronze lub tes tsho. Txhawm rau tiv thaiv kev puas tsuaj ntawm cov khoom graphite pwm, qee qhov kev tiv thaiv oxidation tuaj yeem siv. Tom qab casting ib tug xov tooj ntawm castings, yog hais tias lub puab nto ntawm lub puab yog pom tias yuav tsum tau hlawv tawm, qhov luaj li cas ntawm lub puab qhov ntawm lub puab yuav loj hlob mus rau siv rau casting loj-loj tes tsho. Qingdao Mingyuan Fengyue Cov Khoom Siv Tshiab yog hom tshiab ntawm graphite ua lag luam nrog cov khoom zoo zoo flake graphite hmoov raws li nws lub cev tseem ceeb thiab cov khoom siv high-tech graphite ua nws cov khoom lag luam.
