Carbon electrodes: Properties thiab cov kev siv

Carbon electrodes yog siv rau tej hlau cua cub. Dhau li siv lawv tsim weld hlau tshem tawm tsis xws luag ntawm hlau los xij txiav RIVET thiab kev ua tau zoo lwm yam hauj lwm. Carbon electrodes no yog ua los ntawm hluav taws xob amorphous carbon. Tiav lawm cov khoom uas daim ntawv-dub nto thiab yog yeej rods, tus ntoo khaub lig seem uas txawv los ntawm 6 mus rau 18 millimeters. Standard ntev rods yog 25-70 centimeters.

Rau tej yam los ntawm cov hlau carbon electrodes sharpened cov ces kaum. Yog li, rau cov ua ntawm ferrous co ib kawg ntawm tus pas nrig xyum kaum sab xis ntawm txog 65 degrees. Yuav kom ua tau lub vuam ntawm ferrous hlau cov ntaub ntawv, xws li hardfacing khoom electrode hliav kaum sab xis ntawm 30 degrees.

Thaum lub sij hawm siv thiab ua cov electrodes siv dekstruzii technology los yog molding thiab tshav kub kev kho mob ntau. Lub hauv paus khoom muaj xws li coke los yog thee, thiab ntxiv ntau yam binders (ib, suab, thiab lwm yam). Nyob rau hauv tej rooj plaub, cov pa roj carbon electrode comprise hlau hmoov los yog shavings.

Cov khoom no yuav siv nyob rau hauv ntau yam industries. Lawv yog siv rau tej steel cov ntaub ntawv, ua qhov nyob rau hauv lub doped, carbon thiab tsawg alloy steels. Nyob rau hauv tas li ntawd mus rau lawv txiav siv tooj liab, stainless los yog me me hlau thiab lwm yam alloys siv nyob rau hauv qhov siv thiab ua cov hlau lug nyob rau hauv mechanical engineering, shipbuilding, steel kev lag luam.

Vuam ntawm carbon electrode tau muaj pov thawj los ua ib tug heev zoo. Nws tau muab piv rau lwm yam hom ntawm tej ntau yam zoo. Thaum ua tau zoo Vuam siv ib tug carbon electrode yog siv cov pa roj carbon, compressed cua los yog hluav taws xob tam sim no, uas tso cai rau ua txiav nrog zoo heev hlau tshem tawm. Vuam ua hauj lwm yog ua nrog kev siv ntawm cov compressed cua los yog hluav taws xob arc, uas tsis tsuas yog melts cov hlau tab sis kuj deletes nws tus kheej ntawm cov huab cua kwj.

Qhov no txoj kev ntawm Vuam hlau cov khoom muaj nws tus kheej cov yam ntxwv. Piv txwv li, tag nrho cov ua hauj lwm yuav tsum tau ua xwb nyob rau hauv ib qhov tam sim no, thiab cov arc ntev yuav tsum nyob rau hauv lub chav 6-15 millimeters. Nyob rau hauv cov ntaub ntawv no, lub arc yog cig yooj yim heev thiab muaj ib tug txaus stability. Txawm li cas los, lub arc yuav poob stability, thiab cov electrode yuav yaj ua pa thiab yuav burnt nrog opposite polarity tshwm sim.

Tsim thaum Vuam ntaub ntawv nrog carbon electrodes arc exhibits siab rhiab heev rau huab cua tej yam kev mob (los nag, magnetic dutyu, roj ntws). Ntxiv thiab, thaum nqa tawm vuam ua hauj lwm, uas siv cov pa roj carbon electrodes, lub arc tau txais tsawg efficiency piv nrog cov pa hlau rods. Txawm li cas los, cov nqi ntawm cov pa roj carbon rods tsis tau underestimated. Lawv cia Vuam nonferrous hlau web cov ntaub ntawv, thiab ua surfacing elektroprihvatkah hardmetals nrog ib tug tam sim no ntawm 1 kÅ ntau yam.
