I-coke ene-calcined luhlobo lwe-carburizer kunye ne-petroleum coke yezinto ezahlukeneyo.
Iimpawu eziphambili zeemveliso zegraphite ￠150-￠1578 kunye nezinye iimodeli.Kuyimfuneko kakhulu kumashishini entsimbi kunye nentsimbi, amashishini e-silicon yepolysilicon, amashishini e-emery, ishishini lezixhobo ze-aerospace kunye nezinye iimveliso.
1: Ipetroleum coke
I-petroleum coke yimveliso yepetroleum emnyama okanye emnyama elukhuni eqinileyo enentsimbi ecwebezelayo kwaye inamarhashalala.Yigranular, i-columnar, okanye into efana nenaliti yekhabhoni equkethe iikristale zegraphite ezincinci.
I-petroleum coke iqukethe i-hydrocarbons, i-90-97% yekhabhoni, i-1.5-8% ye-hydrogen, i-nitrogen, i-chlorine, i-sulfure, kunye ne-heavy metal compounds.
I-petroleum coke yimveliso ye-pyrolysis yeoli eluhlaza kwiyunithi yokulibaziseka yokupheka ukuvelisa ioli ekhanyayo kwiqondo lokushisa eliphezulu.
Imveliso yepetroleum coke imalunga ne-25-30% yeoli ekrwada.
Ixabiso layo le-calorific eliphantsi li malunga ne-1.5-2 ngamaxesha amalahle, umxholo womlotha awukho ngaphezu kwe-0.5%, umxholo oguquguqukayo malunga ne-11%, kwaye umgangatho wayo usondele kwi-anthracite.
2: Umgangatho womgangatho wepetroleum coke Ilibazisekile icoke yepetroleum ibhekisa kwicoke eveliswe yiyunithi yokulibaziseka yokupheka, eyaziwa ngokuba yicoke eqhelekileyo, akukho ## umgangatho ohambelanayo.
Okwangoku, amashishini emveliso yasekhaya ikakhulu avelisa ngokomgangatho woshishino SH0527-92 owenziwe yiChina Petrochemical Corporation yangaphambili.
Umgangatho uhlelwa ngokukodwa ngokwe-sulphur content ye-petroleum coke.
Inombolo ye-1 ye-coke ifanelekile ukwenza i-electrode ye-graphite yamandla aqhelekileyo kwi-steelmaking industry, kwaye isetyenziswe njengekhabhoni yokucoca i-aluminium.
Inombolo ye-2 coke isetyenziselwa ukucola i-electrode kunye nokuveliswa kwe-electrode yegraphite kwiseli ye-electrolytic (isithando somlilo) kwishishini lokunyibilikisa i-aluminium.
Inombolo ye-3 coke isetyenziselwa ukuveliswa kwe-silicon carbide (izinto zokugaya) kunye ne-calcium carbide (i-calcium carbide), kunye nezinye iimveliso zekhabhoni, kunye nokuveliswa kweebhloko ze-anode ze-aluminium smelter kunye nokwakhiwa kwe-carbon lining. izitena okanye isithando somlilo esisezantsi kwisithando somlilo.
3: Ezona ZISEBENZAYO zepetroleum coke
I-USES eziphambili ze-petroleum coke ziyi-anode ebhakiweyo kwangaphambili kunye ne-anode paste ye-electrolytic aluminium, ukuveliswa kwekhabhoni ye-carbonizing agent, i-graphite electrode, ukunyibilikisa i-silicon ye-industrial kunye ne-fuel, njl.
Ngokwesakhiwo kunye nenkangeleko ye-petroleum coke, iimveliso ze-petroleum coke zinokwahlulwa zibe yinaliti ye-coke, i-sponge coke, i-projectile coke kunye ne-powder coke:
(1) I-coke efana nenaliti, kunye nesakhiwo esicacileyo senaliti kunye ne-fiber texture, isetyenziswa kakhulu njenge-electrode ye-graphite yamandla aphezulu kunye ne-ultra-high-power graphite electrode kwi-steelmaking.
Ngenxa yokuba inaliti yenaliti ineemfuno eziqinileyo zesalathisi kwimixholo yesulfure, umxholo we-ash, umxholo we-volatile kunye nobuninzi bokwenene, kukho iimfuno ezikhethekileyo kwi-teknoloji yokuvelisa kunye nezinto eziluhlaza ze-coke yenaliti.
(2) I-coke ye-sponge, kunye ne-reactivity ephezulu yeekhemikhali kunye nomxholo ophantsi wokungcola, isetyenziswa kakhulu kwishishini lokunyibilikisa i-aluminium kunye ne-carbon industry.
(3) I-projectile coke okanye i-coke engqukuva: i-spherical in shape kwaye yi-0.6-30mm ububanzi.Ngokuqhelekileyo iveliswa kwi-high-sulfur kunye ne-asphaltene ephezulu kwaye ingasetyenziselwa ukuvelisa amandla, i-samente kunye nezinye izibaso zamashishini.
(4) I-coke ye-powder: iveliswa yinkqubo yokucoca i-fluidized kunye neengqungquthela ezintle (ububanzi: 0.1-0.4mm), umxholo ophezulu we-volatilization kunye ne-coefficient ephezulu yokwandisa i-thermal, ngoko ayikwazi ukusetyenziswa ngokuthe ngqo ekulungiseleleni i-electrode kunye ne-carbon industry.
I-4: I-coke ye-petroleum ene-calcined
Xa i-electrode yegraphite ye-steelmaking okanye i-anode paste (i-electrode enyibilikayo) ye-aluminium kunye ne-magnesium, ukwenzela ukuba i-coke ye-petroleum (coke) ihlangabezane neemfuno, i-coke kufuneka ifakwe i-calcined.
Iqondo lobushushu becalcining liqhelekile malunga ne-1300℃, injongo yalo ikukususa i-naphthol coke volatilization kangangoko kunokwenzeka.
Ngale ndlela, umxholo we-hydrogen we-petroleum coke reproducts unokuncitshiswa, i-graphitization degree ye-petroleum coke inokuphuculwa, amandla aphezulu obushushu kunye nokumelana nobushushu be-graphite electrode kunokuphuculwa, kunye nokuphuculwa kombane we-graphite electrode. .
I-calcining isetyenziselwa ukuvelisa i-graphite electrode, iimveliso ze-carbon paste, isanti yeDayimane, imboni ye-phosphorus yokutya, i-metallurgical industry kunye ne-calcium carbide, phakathi kwayo i-graphite electrode isetyenziswa ngokubanzi.
I-Coke ngaphandle kokubumba ingasetyenziswa ngokuthe ngqo njenge-calcium carbide, i-silicon carbide kunye ne-boron carbide njengezinto zokugaya.
Isenokusetyenziswa ngokuthe ngqo njenge-coke kwishishini le-metallurgical blast furnace okanye i-blast furnace lining ye-carbon brick, ingasetyenziselwa ukuphosa inkqubo ye-compact coke, njl.
