Hunhu hwegraphite electrode yedu

Hunhu hwedugraphite electrode:

1. Mitengo yakagadzikana uye inonzwisisika:

Mutengo we graphite zvinhu unongoda 15% yehuwandu hwakafanana hwemhangura electrode. Parizvino, graphite yava chinhu chakakurumbira chekushandiswa kweEDM, ine mari yakaderera uye yakanyanya kugadzikana kana ichienzaniswa nemagirafu zvinhu.

1. Zviri nyore kucheka uye kugadzirisa
2. 4. Kureruka uye kuderera
3. Kuwanda kwegraphite kunowanzo 1.7-1.9g / cm3 (mhangura ndeye 4-5 nguva yegraphite). Kuenzaniswa nemhangura electrodes, graphite electrodes inoderedza mechanical mutoro panguva iyi. Inonyanya kukodzera kushandisa zviumbwa zvakakura.
4. 5. Kugadzirwa kwakanaka kwekucheka
5. Kuenzaniswa nezvinhu zvesimbi, huwandu hwegraphite hwakagadzirirwa kuve hwakaderera. Iyo ine yakanakisa mechanical processing performance.
6. 6. Bonding effect
7. Gravel inki inogona kusungirirwa kuburikidza nekunamatira, iyo inochengetedza nguva uye mari yezvinhu.
8. 7. Higher resistivity
9. Iyo resistivity (ER) inosarudza kuramba kwezvinhu kusvika pakuyerera kwezvino. A lower resistivity zvinoreva conductivity.

Graphite ine yakanakisa michina yekugadzirisa zvivakwa. Iyo machining kumhanya ye graphite electrodes yakakwira 2-3 nguva yakakwira kupfuura yemhangura electrode. Panguva imwecheteyo, hapana chikonzero chekunetseka nezve burrs mushure mekugadzira graphite.

3. Low thermal kuwedzera coefficient

Nzvimbo yakanyunguduka yemhangura i1080 ℃, nepo CTE yegraphite ingori 1/30 yemhangura pa3650 ℃. Iine kushanda kwakanyatsogadzikana kunyange pakudziya kwekushisa. Kunyangwe mukugadzirisa kweplatinum electrodes, magirafu emagetsi ane zvakakosha.
