Dab tsi yog koom nrog hauv kev cai graphite electrode kev tsim khoom txheej txheem?

Kev cai graphite electrode kev tsim cov txheej txheem cuam tshuam nrog cov kev ua kom tau raws li cov neeg siv khoom, cov cua sov kev teeb tsa, thiab kev ua haujlwm. Tsis zoo li cov qauv hluav taws xob, kev cai tsim cov kab ke tsim hluav taws xob, cov khoom siv, thiab lwm cov txheej txheem siab-} kub kev siv kub.

Cov txheej txheem pib nrog kev sab laj cov ncauj lus kom ntxaws thiab kev tsom xam, cov engineers ua haujlwm tau zoo nrog cov neeg siv khoom kom nkag siab cov txuj ci tshwj xeeb, thiab kev xav tau. Yam xws li electrode lub taub, ntev, xov xwm load muaj peev xwm, thiab kev ua haujlwm kub tau txiav txim siab. Raws li cov ntaub ntawv no, cov ntaub ntawv tsim nyog ntawm graphite yog xaiv {2} {} Nyob ntawm qhov hluav taws xob muaj txiaj ntsig, cua sov kuj, thiab lub zog kho zog.

Cov txheej txheem tsim khoom muaj ntau theem: RAW KHOOM Npaj, kev ua kom sov (yog tias muaj kev kub ntxhov), los txhim kho qhov kub thiab txias tshaj 2,800 degree, thiab thaum kawg, prefision machining. Cov cuab yeej siv kev cai yog qhov tseem ceeb, raws li nws cuam tshuam nrog kev ua tiav cov kev paub tseeb yuav tsum tau, suav nrog cov txheej txheem tseeb kom ua tiav, suav nrog cov qauv tseeb kom ua tiav, suav nrog cov qauv sib xyaw ua ke, thiab cov ntawv sib txuas.

Kev tswj hwm zoo yog kev sib xyaw thoob plaws tag nrho cov txheej txheem. Txhua eldrode raug kuaj xyuas qhov tseeb raug, ceev, cuam tshuam hluav taws xob, thiab lub zog ua kom ntseeg tau tias nws ua tau raws li cov ntaub ntawv ua haujlwm rau nws cov ntawv thov. Cov txuj ci ntsuas siab kuj tseem ua haujlwm los ntsuas cov thermal conductivity thiab oxidation tsis kam.

Qhov zoo dua ntawm kev cai graphite kev tsim cov txheej txheem yog nws muaj peev xwm xa cov electrodes uas tau ua kom zoo dua siv hluav taws xob, txo cov hluav taws xob, thiab txhim kho cua sov kom zoo. Los ntawm muab cov kev daws teeb meem, tus txheej txheem no ua rau cov tuam txhab ua tiav kom ua tiav cov khoom lag luam siab dua, thiab tsim tau ntau dua hauv lawv cov kev ua haujlwm metallurgical.
