Coke-ga Calcined waa nooc ka mid ah kaarburizer-ka iyo kookaha batroolka ee leh qeexitaanno kala duwan.
Tilmaamaha ugu muhiimsan ee alaabada garaafka waa ￠150-￠1578 iyo noocyo kale. Waa lama huraan shirkadaha birta iyo birta, shirkadaha warshadaha ee silicon polysilicon, shirkadaha emery, warshadaha agabka hawada sare iyo alaabada kale.
1: Kookaha batroolka
Kookaha batroolka waa batrool adag oo madow ama cawl madow ah oo leh dhalaal bir ah waana mid daloolo leh. Waa walax kaarboon ah oo u eg granular, columnar, ama irbad oo ka kooban kiristaal graphite oo yar yar.
Kookaha batroolka wuxuu ka kooban yahay hydrocarbons, 90-97% kaarboon, 1.5-8% haydarojiin, nitrojiin, koloriin, sulfur, iyo iskudhisyo bir culus.
Kookaha batroolka waa wax soo saarka ka soo baxa pyrolysis-ka saliidda cayriin ee ku jira cutubka kookaynta dib u dhaca si loo soo saaro saliid fudud heerkul sare.
Wax soo saarka kookaha batroolka waa qiyaastii 25-30% ka mid ah saliidda cayriin.
Qiimaha kalooriyeed ee hooseeya waa qiyaastii 1.5-2 jeer dhuxusha, dambasku kama badna 0.5%, waxa ku jira dambasku waa qiyaastii 11%, tayadiisuna waxay u dhowdahay anthracite.
2: Heerka tayada ee kookaha batroolka Kookaha batroolka ee dib u dhacay waxaa loola jeedaa kookaha ay soo saarto cutubka kookaha ee dib u dhacay, oo sidoo kale loo yaqaan kookaha caadiga ah, ma jiro heer ## oo u dhigma.
Waqtigan xaadirka ah, shirkadaha wax soo saarka gudaha waxay inta badan soo saaraan iyadoo loo eegayo heerka warshadaha SH0527-92 oo ay samaysay Shirkaddii hore ee Shiinuhu ee Batroolka.
Heerka waxaa inta badan loo kala saaraa iyadoo loo eegayo maaddada sulfur ee kookaha batroolka.
Coke-ga lambarka 1aad wuxuu ku habboon yahay sameynta elektroodka graphite-ka ee caadiga ah ee warshadaha birta sameeya, waxaana sidoo kale loo isticmaalaa kaarboon ahaan sifeynta aluminiumka.
Kookaha lambarka 2aad waxaa loo isticmaalaa koolada elektiroonigga ah iyo wax soo saarka elektiroonigga garaafka ee unugyada elektiroonigga ah (foornada) warshadaha dhalaalinta aluminiumka
Kookaha lambarka 3aad waxaa loo isticmaalaa soo saarista carbide-ka silicon (qalabka shiidi) iyo kaalshiyam carbide (kaalshiyam carbide), iyo sidoo kale waxyaabaha kale ee kaarboonka, iyo sidoo kale soo saarista baloogyada anode-ka ee loogu talagalay dhalaaliyaha aluminiumka iyo dhismaha lebenka dahaarka kaarboonka ama salka foornada ee foornada qarxa.
3: ISTICMAALKA UGU WEYN EE KOOLKA BATROOLKA
ISTICMAALKA ugu muhiimsan ee kookaha batroolka waa anode hore loo dubay iyo koollada anode ee aluminiumka elektrolytic-ga, soo saarista kaarboon ee wakiilka kaarboonaynta, electrode graphite, dhalaalinta silikoonka warshadaha iyo shidaalka, iwm.
Sida ku cad qaab-dhismeedka iyo muuqaalka kookaha batroolka, badeecooyinka kookaha batroolka waxaa loo qaybin karaa kookaha irbadda, kookaha isbuunyada, kookaha projectile iyo kookaha budada ah:
(1) Coke-ga u eg irbad, oo leh qaab-dhismeed irbad u eg iyo qaab-dhismeed fiber ah, waxaa inta badan loo isticmaalaa electrode-ka graphite-ka awoodda sare leh iyo electrode-ka graphite-ka awoodda sare leh ee sameynta birta.
Maadaama coke-ka irbadda leh uu leeyahay shuruudo tayo sare leh oo ku saabsan maadada sulfur, maadada dambaska, heerka isbeddelka iyo cufnaanta dhabta ah, waxaa jira shuruudo gaar ah oo ku saabsan tiknoolajiyada wax soo saarka iyo walxaha ceeriin ee coke-ka irbadda.
(2) Kookaha isbuunyada, oo leh falcelin kiimiko oo sareysa iyo wasakh yar, waxaa inta badan loo isticmaalaa warshadaha dhalaalinta aluminiumka iyo warshadaha kaarboonka.
(3) Kookaha matoorka leh ama kookaha wareegsan: waa qaab wareegsan oo dhexroorkiisu yahay 0.6-30mm. Guud ahaan waxaa laga soo saaraa haraaga sulfur sare iyo asphaltene sare waxaana loo isticmaali karaa oo keliya soo saarista korontada, sibidhka iyo shidaalka kale ee warshadaha.
(4) Kookaha budada ah: waxaa lagu soo saaraa habka kookaynta dareeraha ah oo leh walxo yaryar (dhexroor: 0.1-0.4mm), firfircooni sare iyo isku-darka ballaarinta kulaylka oo sarreeya, sidaa darteed si toos ah looguma isticmaali karo diyaarinta elektiroonigga iyo warshadaha kaarboonka.
4: Kookaha batroolka ee la kariyey
Marka elektroodka garaafiga ee loogu talagalay sameynta birta ama koolada anode (elektroodka dhalaalka) ee aluminiumka iyo magnesium, si loo sameeyo kookaha batroolka (coke) oo buuxiya shuruudaha, kookaha waa in la kabaa.
Heerkulka calcining-ka guud ahaan waa qiyaastii 1300℃, ujeeddadiisuna waa in laga takhaluso volatilization-ka naphthol coke intii suurtagal ah.
Sidan, waxaa la dhimi karaa heerka haydarojiinta ee soo saarista kookaha batroolka, heerka garaafka ee kookaha batroolka waa la hagaajin karaa, xoogga heerkulka sare iyo iska caabbinta kulaylka ee kookaha garaafka waa la hagaajin karaa, iyo socodka korantada ee kookaha garaafka waa la hagaajin karaa.
Calcining waxaa inta badan loo isticmaalaa soo saarista elektroodka garaafka, alaabada koollada kaarboonka, ciidda dheemanka, warshadaha fosfooraska heerka cuntada, warshadaha birta iyo kaalshiyamka kalsiyum, kuwaas oo elektroodka garaafka si weyn loo isticmaalo.
Kookaha aan lahayn foorjiin waxaa si toos ah loogu isticmaali karaa sida kaalshiyam carbide, silikoon carbide iyo boron carbide sida walxaha shiididda.
Waxa kale oo si toos ah loogu isticmaali karaa sida coke foornada qaraxa warshadaha birta ama foornada qaraxa leben kaarboon, sidoo kale waxaa loo isticmaali karaa habka shubista coke is haysta, iwm.
