Cov ncauj lus kom ntxaws piav qhia ntawm kev siv cov khoom lag luam graphite

Kev siv cov khoom graphite yog qhov siab dua li qhov peb xav tau, yog li dab tsi yog siv ntawm graphite cov khoom uas peb tab tom paub txog?

1,Siv raws li cov khoom siv

When smelting various alloy steels, ferroalloys, or producing calcium carbide (calcium carbide) and yellow phosphorus using an electric arc furnace or submerged arc furnace, a strong current is introduced into the melting zone of the electric furnace through carbon electrodes (or continuous self baking electrodes - ie electrode paste) or graphitized electrodes to generate an arc, converting electrical energy into heat energy, Thiab raising qhov kub txog ib ncig 2000 degrees Celsius, yog li ntsib cov cai uas yuav tsum tau ua rau smelting lossis cov tshuaj tiv thaiv. Hlau magnesium, txhuas, thiab sodium feem ntau tsim los ntawm molten ntsev electrolysis. Lub sijhawm no, cov ntaub ntawv Anode cov ntaub ntawv electrolytic yog tag nrho cov graphite electrodes lossis txuas ntxiv muab tshuaj txhuam rau cov hluav taws xob (qee zaum ua ntej ci anode). Qhov kub ntawm molten ntsev electrolysis yog feem ntau hauv qab 1000 degrees Celsius. Cov khoom siv anode cov khoom siv tau siv rau hauv ntsev kua kuab elal electrolistry cells Cov khoom siv ua rau cov khoom siv hluav taws xob ntawm lub taub hau rauv ntawm lub rauv taws ua kom muaj nyob rau hauv kev ntau lawm cov pa silicon ntau lawm siv graphitized electrodes. Ntxiv rau cov hom phiaj saum toj no, Carbon thiab Graphite cov khoom tau siv dav siv raws li cov ntaub ntawv tsim kev lag luam nyob rau hauv kev ua kom nrov thiab txhuam. Ib qho ntxiv, lawv kuj tau siv los ua cov pas nrig carbon tov hauv cov roj teeb qhuav

2,Siv raws li cov khoom siv refactory

Vim tias muaj peev xwm ntawm cov pa roj carbon thiab cov khoom siv graphite kom muaj cov roj carbon blocks, xws li corrosion rauv taws thiab corrosion rauv taws, thiab hauv qab thiab ob sab ntawm cov colonfolytic cell. Ntau tus cruciles siv rau smelting precious thiab tsis tshua muaj hlau, raws li graphitized cruciles siv rau melting quartz iav, kuj yog ua los ntawm graphitized billets. Carbon thiab cov khoom lag luam graphite siv raws li cov khoom siv refractory feem ntau yuav tsis siv hauv oxidizing cua. Vim tias cov pa roj carbon lossis graphite grandrates sai sai nyob rau hauv cov kub hauv kev oxidizing huab cua.

3,Siv raws li cov khoom siv corrosion-resistant cov khoom siv

Graphitized electrodes impregnated nrog organic los yog inorganic resins muaj cov yam ntxwv ntawm zoo corrosion, zoo thermal conductivity, thiab qis permeability. Hom lus no yog hu ua impermiteable graphite. Nws yog dav siv nyob rau hauv kev tsim cov cua kub, cov tshuaj tiv thaiv tso tsheb hlau, cov thawv txias, ua kom sov, twj, thiab lwm yam khoom siv. Nws yog dav siv hauv kev lag luam xws li roj av ua kom zoo, roj av, thiab tuaj yeem txuag tau ntau cov ntaub ntawv hlau xws li cov hlau stainless. Kev tsim khoom ntawm impermite tau los ua ib ceg tseem ceeb ntawm kev lag luam carbon.

4,Siv los ua cov khoom siv-tiv taus thiab lubricating

Cov pa roj carbon thiab cov khoom siv graphite tsis yog muaj cov tshuaj ruaj khov, tab sis kuj muaj cov khoom muaj peev xwm zoo. Nws yog feem ntau tsis yooj yim sua kom txhim kho cov hnav tsis kam siv cov khoom siv zawv zawg siv lubricating roj nyob rau hauv cov kev kub ceev, kub, thiab cov mob siab. Graphite hnav-resistant cov ntaub ntawv tuaj yeem ua haujlwm tsis muaj lubricating cov roj hauv cov ntsuas kub ntawm -200 txog 2000 degride ceev (txog 100 metres / thib ob). Yog li no, ntau cov tshuab compressors thiab twj uas thauj cov kev thauj dav dav siv piston rings, thiab cov kabmob ua tau ntawm cov ntaub ntawv graphite. Lawv tsis tas yuav muaj ntxiv rau ntawm cov roj nplua thaum ua haujlwm. Cov khoom siv-resistant yog tsim los ntawm impregnating cov carbon lossis graphite cov ntaub ntawv nrog cov khoom siv organic lossis kua hlau. Graphite emulsion kuj yog ib lub roj nplua khoom zoo rau ntau yam hlau ua (xws li xaim teeb duab thiab raj teeb duab).

5,Raws li qhov kev kub-ntsuas kub thiab cov khoom siv hloov tshiab

Cov qauv siv hauv kev tsim khoom hauv kev tsim khoom, xws li siv cov siv lead ua kom huv, cov hlua khi, cov khoom siv cua sov, yog txhua yam los ntawm cov khoom siv hluav taws xob siab. Graphite rwb thaiv tsev cov laug cam thiab cov hauv paus siv hauv lub tshuab nqus tsev, nrog rau cov khoom siv hluav taws xob, cov pas nrig kub, thiab cov hnab looj, kuj yog ua ntawm cov ntaub ntawv graphite.
