Daim ntawv thov tau txais cov khoom lag luam graphite

1, siv los ua cov khoom siv

Thaum smelting ntau yam alloy alloy, ferrroalloys, lossis tsim cov hluav taws xob muaj hluav taws xob los ntawm cov hluav taws xob hluav taws xob (lossis txuas ntxiv rau tus kheej baking hluav taws xob - I.E. electrode Muab tshuaj txhuam) lossis graphitized electrodes los tsim lub zog hluav taws xob rau hauv lub zog hluav taws xob, thiab ua kom muaj kev sib ntsib ntawm smelting lossis cov tshuaj tiv thaiv. Magnesium, txhuas, thiab sodium feem ntau tsim los ntawm molten ntsev electrolysis. Nyob rau lub sijhawm no, cov khoom siv anode coj ntawm cov electrolytic yog ob qho graphite electrode lossis tus kheej txuas ntxiv 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 coj los tsim cov caustic dej qab zib (sodium hydroxide) thiab chlorine roj tso tsheb hlau electrolysis feem ntau graphite anode. Cov khoom siv ua rau cov khoom siv hluav taws xob ntawm lub taub hau rauv ntawm cov rauv taws ua kom muaj nyob hauv kev tsim cov silicon carbide kuj siv graphite ultrasonic cov duab hluav taws xob. 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. Tsis tas li ntawd, lawv kuj tau siv los ua cov pas nrig carbon ntau hauv cov roj teeb qhuav

2, siv cov khoom siv refactory

Vim yog qhov kub siab tiv thaiv, zoo siab kub lub zog, xws li cov roj carbon thiab corrosion ntawm cov pa roj carbon thiab celly ntawm ferroalloy hluav taws xob Thiab calcium carbide furnaces, thiab hauv qab thiab ob sab ntawm txhuas electrolychncychs. Ntau cov crucibles siv rau smelting precious thiab tsis tshua muaj cov hlau, nrog rau cov crucosite graphite, kuj tau ua los ntawm graphite 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 maj mam hlawv tam sim ntawd nyob rau hauv cov kub hauv oxidizing huab cua.
