Qhov zoo ntawm Graphite li Electrode Khoom
Dec 01, 2022
Dab tsi zoo dua cov khoom siv graphite muaj tshaj tooj liab electrode?
1. Ntau tshaj 90 feem pua ntawm cov khoom siv electrode nyob hauv Europe uas xaiv graphite li cov khoom siv electrode yog graphite. Tooj, ib zaug cov khoom siv electrode tseem ceeb, yuav luag poob nws qhov zoo dua graphite electrode.
2. Vim li cas graphite li electrode:
1) ceev machining ceev: Feem ntau, machining ceev ntawm graphite yog 2 ~ 5 zaug sai dua li tooj liab; EDM ceev yog 2 ~ 3 zaug sai dua li tooj liab.
2) Cov khoom yog qhov nyuaj rau deform: nws muaj qhov pom tseeb zoo hauv kev ua cov txheej txheem nyias nyias; Lub softening point ntawm tooj liab yog hais txog 1000 degrees, uas yog ib qho yooj yim rau deform vim cua sov; Lub sublimation kub ntawm graphite yog 3650 degree; Lub coefficient ntawm thermal expansion tsuas yog 1/30 ntawm tooj liab.
3) Qhov hnyav dua: qhov ntom ntawm graphite tsuas yog 1/5 ntawm tooj liab. Thaum cov electrodes loj siv rau EDM, lub nra ntawm EDM tuaj yeem txo tau zoo; Nws yog qhov tsim nyog rau daim ntawv thov ntawm cov pwm loj.
4) Kev siv hluav taws xob tsawg dua: vim tias cov roj ntsha tseem muaj C atoms, thaum lub tshuab hluav taws xob tawm hluav taws xob, qhov kub siab ua rau C atoms hauv cov roj hluav taws xob decomposed, uas nyob rau hauv lem ua ib tug tiv thaiv zaj duab xis nyob rau saum npoo ntawm graphite electrode los them. rau qhov poob ntawm graphite electrode.
