Cov yam ntxwv ntawm peb graphite electrode

Cov yam ntxwv ntawm pebgraphite electrode:

1. Tus nqi ruaj khov thiab tsim nyog:

Tus nqi ntawm cov khoom siv graphite tsuas yog xav tau 15% ntawm tib lub ntim ntawm tooj liab electrode. Tam sim no, graphite tau dhau los ua cov khoom siv nrov rau EDM daim ntawv thov, nrog cov nqi qis dua thiab ruaj khov dua piv rau cov ntaub ntawv graphite.

1. Yooj yim txiav thiab ua
2. 4. Lub teeb yuag thiab qhov ntom ntom
3. Qhov ceev ntawm graphite feem ntau yog 1.7-1.9g / cm3 (tooj liab yog 4-5 npaug ntawm graphite). Piv rau tooj liab electrodes, graphite electrodes yuav txo cov neeg kho tshuab load thaum tus txheej txheem no. Nws yog qhov tsim nyog rau kev siv cov pwm loj.
4. 5. Kev ua haujlwm zoo
5. Piv nrog rau cov khoom siv hlau, qhov ntim ntawm graphite yog tsim los kom tsawg. Nws muaj zoo heev mechanical processing kev ua tau zoo.
6. 6. Bonding nyhuv
7. Gravel number case tuaj yeem sib txuas los ntawm cov nplaum, uas txuag lub sijhawm thiab cov nqi khoom siv.
8. 7. siab dua resistivity
9. Lub resistivity (ER) txiav txim siab qhov tsis kam ntawm cov khoom mus rau qhov ntws ntawm tam sim no. Qhov qis resistivity txhais tau tias conductivity.

Graphite muaj cov cuab yeej ua haujlwm zoo heev. Lub machining ceev ntawm graphite electrodes yog 2-3 zaug siab dua li ntawm tooj liab electrodes. Nyob rau tib lub sijhawm, tsis tas yuav txhawj xeeb txog burrs tom qab ua cov graphite.

3. Tsawg thermal expansion coefficient

Lub melting point ntawm tooj liab yog 1080 ℃, thaum CTE ntawm graphite tsuas yog 1/30 ntawm tooj liab ntawm 3650 ℃. Nws muaj kev ua haujlwm ruaj khov heev txawm tias qhov kub thiab txias. Txawm nyob rau hauv kev ua cov platinum electrodes, graphite electrodes muaj qhov zoo.
