Inkqubo yokuvelisa i-Recarburizer kunye nemathiriyeli ekrwada
I-recarburizer yinto enekhabhoni.IiCarburizers zongezwa ngexesha lenkqubo yokunyibilikisa ukongeza umxholo wekhabhoni olahlekileyo ngexesha lokunyibilikiswa kwentsimbi.Siyazi ukuba zininzi iintlobo ze-recarburizers, ezifana ne-petroleum coke recarburizers, i-graphite recarburizers eyenziweyo, njl.Inkqubo yerecarburizers yinton?UXiaobian uya kukuxelela malunga nemathiriyeli ekrwada kunye neenkqubo ezifunekayo kwi-recarburizer.
Imathiriyeli ekrwada efunekayo kwi-recarburizers
Zininzi iintlobo zemathiriyeli ekrwada ye-recarburizers, kubandakanya amalahle, ikhabhoni esekwe ngamalahle, icoke, igraphite, icoke yepetroleum ekrwada, njl.njl., apho kukho iindidi ezininzi ezincinci kunye neendidi ezahlukeneyo.
Okwangoku, uninzi lwee-recarburizers kwimarike, kubandakanya i-graphite electrode, i-graphitized petroleum coke, njl., sebenzisa i-petroleum coke eluhlaza.I-petroleum coke ekrwada ifunyanwa ngokufakwa kwe-oyile eshiyekileyo kunye ne-petroleum pitch efunyenwe ngokuxutywa kwe-oyile ekrwada phantsi koxinzelelo lwe-atmospheric okanye i-vacuum.I-petroleum coke eluhlaza inomxholo wokungcola okuphezulu kwaye ayikwazi ukusetyenziswa ngokuthe ngqo njenge-recarburizer.Kufuneka i-calcined okanye i-graphitized.Iirecarburizer ezikumgangatho ophezulu ngokubanzi zifuna igraphitization.Phantsi kweemeko zobushushu obuphezulu, ilungiselelo le-athomu yekhabhoni ikwimilo emikroskopu yegraphite, ngoko ibizwa ngokuba yigraphitization.I-Graphitization inokunciphisa umxholo wokungcola kwi-recarburizer, ukwandisa umxholo wekhabhoni we-recarburizer, kunye nokunciphisa umxholo wesulfure.IiRecarburizers zisetyenziselwa ukugalela, ezinokunyusa kakhulu ubungakanani bentsimbi ezilahliweyo, ukunciphisa ubungakanani bentsimbi yehagu okanye ukonga intsimbi yehagu.
Inkqubo yeCarburizer
Ngenxa yoluhlu olubanzi lwezinto ezikrwada ze-recarburizers, iinkqubo nazo zahlukile, kodwa kukho ezi zintathu zilandelayo:
1. Ukubala
Izinto eziluhlaza zeCarbonaceous zibalwa kwiqondo lokushisa eliphezulu le-1200-1500 ° C ngokungabikho komoya.Ukubala kubangela uluhlu lweenguqu kwisakhiwo kunye neempawu ze-physicochemical zezinto ezahlukeneyo eziluhlaza.Yinkqubo yonyango lobushushu lwe-recarburizer.Zombini i-anthracite kunye ne-petroleum coke ziqulethe umlinganiselo othile wezinto eziguquguqukayo kwaye zifuna ukubala.Noko ke, xa ipetroleum coke nepitch coke zixutywa zize zisetyenziswe ngaphambi kokuba zibalwe, zifanele zithunyelwe kwicalciner ukuze zixutywe nepetroleum coke.
2. Ukuqhotsa
I-roast yinkqubo yokunyanga ukushisa apho ukutya okuluhlaza okucinezelweyo kushushu kwizinga elithile lokufudumeza kwindawo yokukhusela kwisithando somlilo phantsi kwemeko yokwahlula umoya.
Injongo yokuqhotsa kukuphelisa ukuguquka kwezinto.Ngokubanzi, malunga neentlobo ezili-10 zee-volatiles ziyakhutshwa emva kokuqhotsa.Ke ngoko, isivuno sokuqhotsa siqhelekile ngama-90;i-binder i-coked, kwaye imveliso yosiwe ngokwemiqathango ethile yenkqubo, ukwenzela ukuba i-binder iphekwe, kwaye inethiwekhi ye-coke yenziwe phakathi kwamasuntswana ezinto ekrwada, edibanisa ngokuqinileyo zonke izinto eziluhlaza kunye nobukhulu bamasuntswana ahlukeneyo.Yenza # # iimveliso zineempawu ezithile zomzimba kunye neekhemikhali.Phantsi kweemeko ezifanayo, ukuphakama kwezinga lokupheka, ngcono umgangatho;kwimeko yejometri esisigxina, imveliso iya kuthambisa kwaye i-binder iya kufuduka ngexesha lokubhaka.Njengoko iqondo lokushisa linyuka, inethiwekhi ye-coking yenziwa, eyenza lukhuni umkhiqizo.Ngoko ke, imilo yayo ayitshintshi njengoko ubushushu bukhula.
3. Extrusion
Injongo yenkqubo ye-extrusion kukwenza i-raw material idlule kwi-mold yesimo esithile phantsi koxinzelelo, kwaye ibe yi-billet enemilo ethile kunye nobukhulu emva kokudityaniswa kunye nokukhubazeka kweplastiki.Inkqubo yokubumba i-extrusion yinkqubo yokuguqulwa kweplastiki ye-paste.Inkqubo ye-extrusion yenzeke kwigumbi lezinto eziphathekayo kunye nombhobho ogobileyo.Izinto ezishushu kwigumbi zityhalwa yi plunger ephambili ngasemva.Ukususwa okunyanzelwayo ngokuqhubekayo kwerhasi kwizinto eziluhlaza, ukunyanzeliswa okuqhubekayo kwezinto eziluhlaza, kunye nokuhamba ngaxeshanye kwezinto eziluhlaza ukuya phambili.Xa izinto eziluhlaza zihamba kwindawo ye-cylindrical yegumbi lezinto eziphathekayo, i-raw material ingathathwa njengento ehamba ngokuzinzileyo, kwaye i-particle nganye layer ihamba ngokufana.Xa imathiriyeli ekrwada ingena kumbhobho we-extrusion kwaye ine-arc-shaped deformation, i-raw material ekufutshane nodonga lombhobho iya kufumana ukuxhathisa okukhulu okukhuphisanayo njengoko iqhubela phambili, kwaye umaleko wezinto ezibonakalayo uqala ukugoba.Izinto eziluhlaza zinezantya ezahlukeneyo eziqhubela phambili, kunye nenkqubela phambili yezinto zangaphakathi.Ke ngoko, ukuxinana kwemveliso ecaleni kwendlela yeradial ayifani, ngaloo ndlela ivelisa uxinzelelo lwangaphakathi olubangelwa ngamazinga ahlukeneyo okuqukuqela kwemigangatho yangaphakathi nangaphandle kwibhloko ekhutshiweyo.Emva kokuba i-paste ingene kwinxalenye ye-deformation echanekileyo, ikhutshwe kwaye yenziwe.
Indlela ye-extrusion idinga ukongeza i-binder eninzi yokubumba, kwaye umxholo wekhabhoni ngokubanzi awuhambelani neemfuno ze-recarburizers ezikumgangatho ophezulu.Umgubo wegraphite oxiniweyo, ngenxa yokuba ibhloko eqinileyo, ayinayo i-porous structure, ngoko ke isantya sokufunxa kunye nesantya sokufunxa asilungile njenge-calcined kunye ne-calcined recarburizers.
