Kev txhais thiab kev tsim kho yooj yim

Lub graphite electrode yog lub cev cylindrical ntawm cov khoom tsim cov pa roj carbon monoxide ntawm txhua qhov kawg, siv los ua tam sim no rau hauv hluav taws xob arc rauv. Nominal diameters khiav los ntawm kwv yees li 75 hli rau cov me me mus txog 750 hli rau qhov loj tshaj plaws ultra- siab- fais fab kev teeb tsa, thiab ib ntu yog feem ntau 1,800, 2,100 lossis 2,400 mm ntev. Lub cev yog tsim los ntawm ib tug muab tub lim coke los yog ib txwm coke thiab ib tug binder ntawm thee tar suab, ces tsim, ci, graphitised thiab machined. Txhua lub tshuab hluav taws xob tau muab nrog lub txiv mis sib txuam uas txuas rau hauv lub qhov (sockets) thiab koom nrog ib ntu mus rau lwm qhov.

Yuav Ua Li Cas Electrode

Cov muab tub lim yog crushed, milled, tshuaj ntsuam thiab tov nrog suab, ces tsim los ntawm extrusion los yog nias. Lub cev ntsuab yog ci ntawm li 800 txog 1,000 degrees Celsius kom cov binder carbonises thiab khi cov coke hais rau hauv ib qho khoom loj. Cov qib xaiv tau impregnated nrog suab thiab rov- ci kom nce qhov ceev ua ntej kev kho cua sov zaum kawg. Lub cev ci ces dhau los ntawm lub qhov cub graphitisation ntawm 2,500 txog 3,000 degrees Celsius, qhov twg cov pa roj carbon lattice tau txiav txim siab graphite. Thaum kawg lub cev yog machined rau nws dimension series thiab cov sockets raug txiav nrog ib tug tapered xov.

Qib thiab Dimension Series

Cov hluav taws xob tau muab los ua lub zog tsis tu ncua, lub zog siab thiab ultra- qib siab zog, feem ntau yog RP, HP thiab UHP. Cov qib sib txawv feem ntau ntawm qhov ceev tam sim no lawv tuaj yeem nqa tau thiab hauv cov khoom siv raw: cov qib tsis tu ncua lees txais qis dua tam sim no, thaum ultra- siab- qib zog yog tsim los ntawm rab koob coke nrog cov khoom ntxiv uas txo qis coefficient ntawm thermal expansion thiab hluav taws xob tiv thaiv. Qib cov npe xws li UHP400, UHP500 thiab UHP600 hais lub nominal txoj kab uas hla nyob rau hauv millimeters thiab hais txog lub peev xwm tam sim no.

Kem ua haujlwm li cas

Peb cov electrodes raug tshem tawm hla lub cub hluav taws xob hauv ib daim duab peb sab. Txhua tus yog tuav los ntawm ib lub clamp ntawm kab hluav taws xob uas tseem nqa tam sim no los ntawm lub tshuab hloov pauv los ntawm cov dej -cov busbars txias. Lub ntsis yog txo kom txog thaum lub arc ntaus ntawm cov graphite thiab cov seem nqi. Raws li cov lus qhia tau noj, kem yog swb, thiab thaum ib ntu dhau los ua ntu ntu tshiab yog screwed rau saum. Lub rooj sib txoos yog li ntawd tus neeg xyuas pib uas txuas ntxiv txuas ntxiv thaum lub tshuab hluav taws xob nyob twj ywm hauv kev ua haujlwm.

Lub luag haujlwm hauv Steelmaking thiab Lwm Lub Rauv

Hluav taws xob arc rauv siv qhov loj tshaj plaws ntawm graphite electrodes thoob ntiaj teb, vim hais tias lub arc yog tib txoj kev uas yuav xa ob peb megawatts ntawm lub hwj chim ncaj qha mus rau ib tug seem nqi. Cov khoom qub no yog siv rau hauv cov qhov cub hluav taws xob rau kev ua kom zoo dua qub, hauv submerged arc furnaces ua ferroalloys, silicon hlau, calcium carbide thiab daj phosphorus, thiab hauv qee qhov kev teeb tsa ncaj qha tam sim no. Nyob rau hauv txhua rooj plaub, cov electrode raug xaiv raws li qhov tam sim no, txoj kab uas hla yuav tsum tau thiab kev huv huv xav tau los ntawm cov khoom kawg.

Cov lus nug nquag

Q: Dab tsi yog graphite electrode hauv cov ntsiab lus yooj yim?
Nws yog cylindrical, consumable carbon pas nrig uas nqa hluav taws xob tam sim no rau hauv arc rauv thiab tsim cov arc uas melts seem hlau los yog lwm yam khoom siv.

Q: Cov ntaub ntawv dab tsi yog siv los ua ib qho?
Ib tug muab tub lim ntawm koob coke los yog roj av coke ib txwm thiab ib lub pob zeb tar pitch binder. Cov sib tov yog tsim, ci, graphitised ntawm 2,500 mus rau 3,000 degrees Celsius thiab ces machined.

Q: Cov qib RP, HP thiab UHP txhais li cas?
Lawv sawv ntsug rau lub zog tsis tu ncua, lub zog siab thiab ultra- lub zog siab, thiab lawv piav qhia txog qhov ceev tam sim no uas cov electrode nqa tau. UHP qib siv koob coke thiab nqa qhov ceev tshaj plaws tam sim no.

Q: Dab tsi yog txoj kab uas hla thiab ntev npaum li cas?
Nominal diameters feem ntau ncav cuag 75 hli mus rau 750 hli, thiab cov qauv ntu ntev yog 1,800, 2,100 thiab 2,400 hli, nrog cov seem ntev rau cov cub tawg loj heev.

Q: Cov seem electrode koom nrog li cas?
Ib daim kab xev - xov graphite txiv mis screws rau hauv lub qhov (socket) ntawm txhua qhov kawg ntawm ntu. Cov txiv mis yog tsim los ntawm denser graphite vim lawv nqa tag nrho tam sim no thiab thauj khoom ntawm qhov sib koom ua ke.

Q: Dab tsi yog graphite electrodes siv?
Feem ntau nyob rau hauv hluav taws xob arc rauv steelmaking, tab sis kuj nyob rau hauv ladle refining, ferroalloy thiab silicon submerged arc furnaces, calcium carbide thiab daj phosphorus furnaces thiab ib co direct tam sim no arc units.
