Cov txiaj ntsig thiab qhov tsis zoo ntawm cov graphite electrodes piv rau cov hlau electrodes ib txwm muaj yog dab tsi?

Cov txiaj ntsig

1. Kev Ua Haujlwm Ceev Dua
   Cov hluav taws xob graphite muab kev ua haujlwm ceev 2-3 zaug sai dua li cov hluav taws xob tooj liab, tshwj xeeb tshaj yog pom tseeb hauv kev ua haujlwm ntawm cov hluav taws xob nyias-rib. Nrog rau kev tiv thaiv txiav tsuas yog 1/5 ntawm cov tooj liab, graphite ua rau muaj kev ua haujlwm zoo dua thiab txo lub sijhawm ua tiav.

2. Sib dua
   Graphite muaj qhov ceev tsuas yog 1/5 ntawm tooj liab, txo qhov hnyav ntawm cov cuab yeej siv tshuab thiab txo qhov hnav ntawm cov khoom siv, ua rau nws tsim nyog rau cov pwm loj thiab cov electrodes.

3. Cov Coefficient Kev Nthuav Dav Thermal Qis
   Graphite tus coefficient thermal expansion tsuas yog 1/30 ntawm tooj liab, ua kom muaj kev hloov pauv tsawg kawg nkaus thaum lub sijhawm ua haujlwm kub siab thiab tswj kev ua haujlwm siab dua, tshwj xeeb tshaj yog rau cov tav tob, nqaim thiab cov khoom nyias-phab ntsa.

4. Kev Hnav Tsawg
   Thaum lub sijhawm ua haujlwm tawm, cov pa roj carbon hauv cov kua dielectric yuav lwj thaum kub siab thiab tsim ib daim zaj duab xis tiv thaiv rau ntawm qhov chaw ntawm graphite electrode, ua kom cov electrode puas. Qhov sib txawv, cov electrodes tooj liab feem ntau tsim cov burrs, xav tau kev ua tiav tes ntxiv.

5. Tsis muaj burr thiab yooj yim rau polish
   Cov hluav taws xob graphite tsis tawm cov burrs tom qab ua haujlwm, tshem tawm qhov xav tau kev ua tiav tom qab thiab ua kom yooj yim rau kev tsim khoom tsis siv neeg. Tsis tas li ntawd, lawv qhov kev tiv thaiv kev txiav qis ua rau kev sib tsoo thiab kev txhuam yooj yim.

6. Siv nyiaj tsawg
   Nrog rau tus nqi tooj liab nce siab hauv xyoo tas los no, cov hluav taws xob graphite tseem ruaj khov hauv tus nqi. Ntxiv mus, cov hluav taws xob graphite pheej yig dua 30% -60% dua li cov hluav taws xob tooj liab ntawm tib lub ntim.

7. Kev Ua Haujlwm Kub Siab Zoo heev
   Cov hluav taws xob graphite muaj qhov kub sublimation txog li 3650 ° C, siab dua qhov kub yaj ntawm tooj liab (1083 ° C), ua kom muaj kev ruaj khov hauv qhov chaw kub siab thiab tsim nyog rau kev siv tshuab fais fab siab, tam sim no siab.

8. Zoo tshaj plaws hauv kev siv tshuab ua cov duab sib xyaw ua ke
   Cov electrodes graphite yooj yim ua rau cov duab geometries nyuaj, ua tau raws li qhov xav tau ntawm cov pwm precision thiab cov khoom tsis sib xws, thaum cov electrodes tooj liab ntsib teeb meem ntau dua hauv kev siv cov duab nyuaj.

Qhov tsis zoo

1. Lub Zog Kho Tshuab Qis Dua
   Cov hluav taws xob graphite muaj zog tsawg heev, ua rau lawv yooj yim tawg ntawm cov ces kaum ntse ntse, tshwj xeeb tshaj yog thaum lub sijhawm ua haujlwm tsis zoo. Yuav tsum tau txiav me me nrog cov nqi pub siab kom tsis txhob tawg lossis tawg ntawm cov ces kaum.

2. Kev Tsim Pluav Hmoov
   Kev siv cov graphite electrodes ua rau muaj hmoov av ntau, ua rau yuav tsum muaj cov txheej txheem kaw thiab rho hmoov av tshwj xeeb los tiv thaiv cov cuab yeej siv tshuab thiab kev noj qab haus huv ntawm tus neeg teb xov tooj.

3. Kev Ua Haujlwm Tsis Zoo hauv Wire EDM
   Hauv kev siv tshuab hluav taws xob tso tawm hlau (Wire EDM), cov electrodes graphite qhia txog kev txiav ceev li ntawm 40% qeeb dua li cov electrodes tooj liab thiab yooj yim tawg hlau, ua rau lawv tsis haum rau kev siv hlau txiav siab.

4. Kev Txwv ntawm Qhov Roughness ntawm Qhov Chaw
   Kev ua kom tau qhov roughness ntawm qhov chaw qis dua VDI12 (Ra0.4μm) yog qhov nyuaj nrog cov graphite electrodes. Rau kev ua kom tiav daim iav, cov electrodes tooj liab tseem yog qhov kev xaiv zoo tshaj plaws.

5. Qhov nyuaj hauv kev siv dua tshiab
   Cov khoom seem graphite electrode muaj tus nqi rov ua dua tshiab tsawg thiab nyuaj rau siv dua, ua rau cov nqi siv ntau ntxiv thiab cuam tshuam rau ib puag ncig.

6. Kev tawg yooj yim thiab kev cuam tshuam rau kev tawg
   Cov electrodes graphite yog cov khoom tawg yooj yim, tshwj xeeb tshaj yog cov electrodes nyias lossis nqaim, uas yooj yim tawg thaum muaj zog sab nraud, uas yuav tsum tau ua tib zoo tuav.

7. Tsis haum rau kev siv tshuab ua kom cov khoom tawm ntawm qhov chaw zoo
   Rau kev ua kom cov nplaim tawm zoo uas xav tau qhov tiav ntawm qhov chaw qis dua VDI12 (Ra0.4μm), cov electrodes graphite ua haujlwm tsis zoo dua li cov electrodes tooj liab, ua rau nws nyuaj rau ua kom tau raws li qhov yuav tsum tau ua ntawm qhov chaw siab.
