Alaabta ceeriin ee soo saarista elektaroonigga garaafyada waxaa ka mid ah kookaha batroolka, coke irbadda iyo garoonka daamurka dhuxusha:

Coke batroolku waa badeeco adag oo gubanaysa oo lagu helo in la karsado hadhaaga batroolka iyo garoonka batroolka.Midabku waa madow iyo dalool, cunsurka ugu weyn waa kaarboon, waxa ku jira dambaskuna aad buu u hooseeyaa, guud ahaan waxa uu ka hooseeyaa 0.5%.Coke batroolku waa nooc ka mid ah kaarboon si fudud loo sawiray.Coke batroolka ayaa si weyn loogu isticmaalaa warshadaha kiimikada, birta iyo warshadaha kale.Waa alaabta ceeriin ee ugu weyn ee soo saarista alaabta garaafyada macmalka ah iyo alaabada kaarboon ee aluminium elektrolytic ah.

Marka loo eego heerkulka daaweynta kulaylka, kookaha batroolka waxaa loo qaybin karaa kookaha cagaaran iyo kookaha calcined.Midka hore waa kookaha batroolka ee lagu helo kookaynta daahitaanka, kaas oo ka kooban xaddi badan oo walxo isbedbeddelaya oo leh awood farsamo oo hooseeya.Coke calcined waxaa lagu helaa calcining coke cagaaran.Inta badan wershadaha sifaynta ee Shiinaha waxay soo saaraan oo kaliya kookaha cagaarka ah, inta badan hawlaha calcination waxaa lagu fuliyaa dhirta kaarboonka.

Coke batroolka waxaa loo qaybin karaa kookaha baaruudda sare (in ka badan 1.5% baaruud), kookaha baaruudda dhexdhexaadka ah (0.5%-1.5% sulfur content) iyo kookaha baaruudka hooseeya (in ka yar 0.5% sulfur content).Electrodes graphite iyo alaabada kale ee garaafyada macmalka ah ayaa guud ahaan la soo saaraa iyadoo la isticmaalayo kookaha baaruudda hoose.

Coke irbadu waa nooc ka mid ah kookaha oo leh maro dhogor leh oo cad, iskudar balaadhinta kulaylka hoose iyo garaafaynta fudud.Marka block coke la jabiyo, waxa loo qaybin karaa qaybo dhaadheer oo dhuuban (dhererka ilaa ballaca saamiga guud ahaan waa ka sarreeya 1.75) sida ay texture.Qaab dhismeedka fibroeska anisotropic waxaa lagu arki karaa mikroskoob ka hooseeya, sidaas darteed waxaa loo yaqaannaa coke irbad.

Anisotropy ee sifooyinka jireed iyo farsamada ee coke cirbadda waa mid aad u muuqda.Jihada isku midka ah ee dhidibka dheer ee qaybaha ayaa leh koronto iyo kulayl wanaagsan, iyo isku-dhafka ballaarinta kulaylka ayaa hooseeya.Inta lagu jiro qaabaynta extrusion, faashashka dhaadheer ee qaybaha ugu badan ayaa loo habeeyaa jihada extrusion.Sidaa darteed, coke cirbaddu waa alaabta ceeriin ee muhiimka ah ee lagu soo saaro korantada garaafyada awoodda sare leh ama ultra-high-powered.Electrodes-ka garaafiga ah ee la sameeyay waxay leeyihiin iska caabin hoose, iskudar balaadhin kuleyl yar, iyo iska caabin shoog kulayl oo wanaagsan.

Coke irbadu waxa ay u qaybsantaa coke irbad saliid ku salaysan oo laga soo saaray hadhaaga batroolka iyo coke irbad dhuxul ku salaysan oo laga soo saaray garoonka daamurka dhuxusha la safeeyey.

Dhererka daamurka dhuxusha waa mid ka mid ah wax soo saarka ugu muhiimsan ee farsamaynta daamurka dhuxusha.Waa isku dhaf ah noocyo kala duwan oo kaarboon ah, madaw sare viscosity semi-adag ama adag heerkulka qolka, iyada oo aan dhibic dhalaalaysa go'an, jilicsan ka dib kulaylka, ka dibna dhalaali, oo leh cufnaanta 1.25-1.35g/cm3.Sida laga soo xigtay barta jilcintu waxay u qaybsan tahay heerkul hooseeya, dhexdhexaad ah iyo heerkul sarreeya oo saddex ah.Wax-soo-saarka asphalt heerkulka dhexdhexaadka ah waa 54-56% kan daamurka dhuxusha.Halabuurka qashin-qubka dhuxusha waa mid aad u adag, kaas oo la xidhiidha sifooyinka daamurka dhuxusha iyo waxa ku jira heteroatoms, iyo sidoo kale waxaa saameeya nidaamka tignoolajiyada coking iyo xaaladaha habaynta ee daamurka dhuxusha.Waxaa jira tilmaamo badan oo lagu garto sifooyinka asphalt-ka dhuxusha, sida barta jilicsan ee asphalt, walaxda aan la karin karin ee toluene (TI), maaddada quinoline insoluble (QI), qiimaha coking iyo hantida rheological ee asphalt dhuxusha.

Dhererka dhuxusha waxaa loo isticmaalaa sida xidhaha iyo wakiilka impregnation ee warshadaha kaarboon.Aasaasheedu waxay saameyn weyn ku leeyihiin habka wax soo saarka iyo tayada alaabta kaarboonka.Binder asphalt guud ahaan waxay isticmaashaa barta jilicsan ee dhexdhexaadka ah, qiimaha sareeyo, heerkulka dhexdhexaadka ah ee beta sare ama heerkulka dhexdhexaadka ah ee la beddelay, wakiilka impregnating si loo isticmaalo barta jilicsan ee hoose, QI hoose, rheology waxay noqon kartaa asphalt heerkul dhexdhexaad ah.

• Codsiga korantada graphite

Electrode graphite waxa uu leeyahay adeegsi badan oo kala duwan, inta badan loo isticmaalo birta foornada korontada, foornada kulaylka, foornada iska caabinta, iwm.

1. Graphite electrode waxaa loo isticmaalaa foornada birta samaynta ee arc

Isticmaalayaasha ugu muhiimsan ee birta foornada korontada, farsamada foornada korontada ayaa ah isticmaalka graphite electrode galay foornada hadda, xoog xoog leh ee dhamaadka hoose ee korantada iyada oo loo marayo dheecaanka gaaska, isticmaalka arc wuxuu dhalinayaa kulaylka dhalada, marka loo eego cabbirka awoodda foornada korontada, oo leh dhexroor kala duwan ee electrodes graphite, si ay u sameeyaan isticmaalka joogtada ah ee electrodes, electrodes by thread electrode xiriir wadajir ah, The graphite electrode loo isticmaalo steelmaking xisaabiyaa qiyaastii 70-80% ee wadarta cadadka graphite electrode.

2. Isticmaalaha macdanta kuleylka foornada korontada

Foornada macdanta waxaa inta badan loo isticmaalaa soo saarista ferroalloy, silicon saafi ah, fosfooraska jaalaha ah, matte iyo kaarbiid calcium.Sifooyinkeeda ayaa ah in qaybta hoose ee korantada korantada ay ku duugan tahay qarashka, sidaas darteed marka lagu daro kulaylka ka dhalanaya arc ee u dhexeeya saxanka iyo kharashka, hadda iyada oo loo marayo kharashka caabbinta kharashka ayaa sidoo kale dhalinaysa kulayl, mid kasta Tan Silicon waxay u baahan tahay inay isticmaasho 150kg/graphite electrode, tan kasta oo fosfooraska jaalaha ah waxay u baahan tahay inay isticmaasho qiyaastii 40kg graphite electrode.

3, foornada iska caabinta

Wax soo saarka alaabta graphite leh foornada graphitization, foornada dhalada dhalaalaysa iyo wax soo saarka foornada carbide silicon waa foornada iska caabinta, foornada lagu rakibay caabbinta kuleylka caajiska, sidoo kale waa shayga kuleylka.Guud ahaan, korantada garaafiga korantada waxaa la geliyaa gidaarka madaxa foornada ee dhamaadka weelka, sidaa darteed korantada korantada si joogto ah looma isticmaalo.

Intaa waxaa dheer, tiro badan oo bannaan electrode graphite ayaa sidoo kale loo isticmaalaa ka baaraandegidda galay noocyo kala duwan oo crucible, doon graphite, caaryada kululaynta kulul iyo vacuum foornada korontada jidhka kululaynta iyo alaabta kale ee gaarka ah.Tusaale ahaan, warshadaha galaaska quartz, 10t graphite electrode maran ayaa looga baahan yahay wax soo saarka tuubada capacitor kasta 1t, iyo 100kg electrode banaan ayaa la wada baabbi'iyey ee 1t quartz leben kasta.
