Cov txiaj ntsig ntawm cov graphite electrodes
1: Qhov nyuaj ntawm cov pwm geometry thiab kev sib txawv ntawm cov khoom siv tau ua rau muaj qhov xav tau siab dua thiab siab dua rau qhov tseeb ntawm lub tshuab hluav taws xob. Qhov zoo ntawm graphite electrodes yog kev ua tiav yooj yim dua, kev tshem tawm siab ntawm kev siv hluav taws xob, thiab kev poob graphite tsawg. Yog li ntawd, qee tus neeg siv khoom siv tshuab hluav taws xob tso tseg cov electrodes tooj liab thiab hloov mus rau graphite electrodes. Tsis tas li ntawd, qee cov electrodes zoo li tshwj xeeb tsis tuaj yeem ua los ntawm tooj liab, tab sis graphite yooj yim dua rau cov duab, thiab cov electrodes tooj liab hnyav thiab tsis haum rau kev ua cov electrodes loj. Cov yam no tau ua rau qee tus neeg siv khoom siv tshuab hluav taws xob siv graphite electrodes.
2: Cov hluav taws xob graphite yooj yim dua rau kev ua, thiab qhov ceev ntawm kev ua yog sai dua li cov hluav taws xob tooj liab. Piv txwv li, siv cov thev naus laus zis milling los ua graphite, nws qhov ceev ntawm kev ua yog 2-3 zaug sai dua li lwm cov hlau ua thiab tsis xav tau kev ua ntxiv tes, thaum cov hluav taws xob tooj liab xav tau kev sib tsoo tes. Ib yam li ntawd, yog tias lub chaw ua haujlwm graphite ceev ceev siv los tsim cov hluav taws xob, qhov ceev yuav nrawm dua thiab qhov ua tau zoo yuav siab dua, thiab yuav tsis muaj teeb meem plua plav. Hauv cov txheej txheem no, kev xaiv cov cuab yeej nrog qhov nyuaj thiab graphite tsim nyog tuaj yeem txo cov cuab yeej hnav thiab kev puas tsuaj ntawm tooj liab. Yog tias koj piv tshwj xeeb lub sijhawm milling ntawm graphite electrodes thiab cov hluav taws xob tooj liab, graphite electrodes yog 67% sai dua li cov hluav taws xob tooj liab. Hauv kev siv hluav taws xob tso tawm, kev ua cov hluav taws xob graphite yog 58% sai dua li cov hluav taws xob tooj liab. Hauv txoj kev no, lub sijhawm ua haujlwm raug txo qis heev, thiab cov nqi tsim khoom kuj raug txo qis.
3: Tus qauv tsim ntawm graphite electrode txawv ntawm cov electrode tooj liab ib txwm muaj. Ntau lub Hoobkas pwm feem ntau muaj cov kev tso cai sib txawv rau kev ntxhib thiab ua tiav ntawm cov electrodes tooj liab, thaum graphite electrodes siv yuav luag tib yam kev tso cai. Qhov no txo cov lej ntawm CAD / CAM thiab kev ua tshuab. Vim li no ib leeg, Txaus kom txhim kho qhov tseeb ntawm cov pwm qhov ntau.
Tau kawg, tom qab lub Hoobkas pwm hloov ntawm cov electrodes tooj liab mus rau graphite electrodes, thawj qhov uas yuav tsum meej yog yuav siv cov ntaub ntawv graphite li cas thiab xav txog lwm yam cuam tshuam. Niaj hnub no, qee tus neeg siv khoom ntawm cov tshuab hluav taws xob pab pawg siv graphite rau electrode discharge machining, uas tshem tawm cov txheej txheem ntawm pwm qhov chaw polishing thiab tshuaj polishing, tab sis tseem ua tiav qhov chaw tiav. Yog tsis nce lub sijhawm thiab cov txheej txheem polishing, nws tsis yooj yim sua rau cov electrode tooj liab los tsim cov khoom ua haujlwm zoo li no. Tsis tas li ntawd, graphite tau muab faib ua ntau qib sib txawv. Cov txiaj ntsig zoo tshaj plaws tuaj yeem ua tiav los ntawm kev siv cov qib tsim nyog ntawm graphite thiab hluav taws xob hluav taws xob tso tawm cov kev cai hauv qab cov ntawv thov tshwj xeeb. Yog tias tus neeg teb xov tooj siv cov kev cai tib yam li cov electrode tooj liab ntawm lub tshuab hluav taws xob siv cov electrodes graphite, Tom qab ntawd qhov tshwm sim yuav tsum poob siab. Yog tias koj xav tswj cov khoom siv ntawm cov electrode nruj me ntsis, koj tuaj yeem teeb tsa cov electrode graphite hauv lub xeev tsis poob (poob tsawg dua 1%) thaum lub sijhawm machining ntxhib, tab sis cov electrode tooj liab tsis siv.
Graphite muaj cov yam ntxwv zoo li no uas tooj liab tsis tuaj yeem sib piv:
Kev ua haujlwm ceev: kev kub ceev milling rough machining yog 3 zaug sai dua li tooj liab; kev kub ceev milling finishing yog 5 zaug sai dua li tooj liab
Kev siv tshuab tau zoo, tuaj yeem paub txog cov qauv geometric nyuaj
Lub teeb yuag, qhov ceev yog tsawg dua 1/4 ntawm tooj liab, electrode yog yooj yim rau clamp
tuaj yeem txo cov lej ntawm cov electrodes ib leeg, vim tias lawv tuaj yeem muab sib xyaw ua ke rau hauv ib qho electrode ua ke
Zoo thermal stability, tsis muaj deformation thiab tsis muaj kev ua burrs
