Dab tsi zoo yog cov khoom siv graphite muaj tshaj tooj liab pwm electrodes

Dab tsi zoo yog cov khoom siv graphite muaj tshaj tooj liab pwm electrodes?

1. Xaiv cov graphite ua cov khoom siv electrode Ntau tshaj 90% ntawm cov khoom siv electrode hauv Europe yog graphite. Tooj liab, uas yog ib zaug cov khoom siv hluav taws xob tseem ceeb, yuav luag poob nws qhov zoo piv rau graphite electrodes.

2. Yog vim li cas siv graphite ua ib qho electrode:

1. Kev ua haujlwm nrawm dua: Raws li ib txwm muaj, cov tshuab ua haujlwm ceev ntawm graphite tuaj yeem yog 2 mus rau 5 npaug sai dua li tooj liab; thiab qhov tso tawm ceev yog 2 mus rau 3 zaug sai dua li ntawm tooj liab;

2. Cov khoom siv tsis tshua muaj deform: Nws muaj qhov pom tseeb zoo hauv kev ua cov txheej txheem nyias nyias; lub softening point ntawm tooj liab yog nyob ib ncig ntawm 1000 degrees, thiab nws yog ib qho yooj yim mus deform vim tshav kub; sublimation kub ntawm graphite yog 3650 degrees; thermal expansion coefficient tsuas yog 1/30 ntawm cov tooj liab.

3. Qhov hnyav dua: Qhov ntom ntawm graphite tsuas yog 1/5 ntawm cov tooj liab. Thaum cov electrodes loj yuav raug tso tawm, nws tuaj yeem txo lub nra ntawm cov cuab yeej siv tshuab (EDM); nws yog qhov tsim nyog rau daim ntawv thov ntawm cov pwm loj.

4. Kev siv hluav taws xob tsawg dua; Txij li thaum cov roj tseem ceeb kuj muaj C atoms, thaum lub sij hawm tso tawm machining, qhov kub siab ua rau C atoms nyob rau hauv lub txim roj yuav decomposed, thiab ces tsim ib tug tiv thaiv zaj duab xis nyob rau saum npoo ntawm graphite electrode, compensating rau qhov poob ntawm graphite electrode.

3. Muab khoom thiab ntim:

Cov khoom lag luam graphite electrode tuaj yeem ua tiav raws li cov duab kos raws li cov neeg siv khoom tshwj xeeb xav tau, thiab cov ntim khoom yog lub thawv ntoo ntim thiab thawv ntim ntim (xaiv raws li qhov loj ntawm graphite electrode, loj graphite electrodes tau ntim rau hauv cov thawv ntoo, thiab cov graphite me me. electrodes tau ntim rau hauv thawv.)
