Calcined coke wani nau'in carburizer ne da man fetur na takamaiman bayanai daban-daban.
Babban ƙayyadaddun bayanai na samfuran graphite sune ￠150-￠1578 da sauran samfura. Yana da mahimmanci ga kamfanonin ƙarfe da ƙarfe, kamfanonin silicon polysilicon na masana'antu, kamfanonin emery, masana'antar kayan sararin samaniya da sauran kayayyaki.
1: Man fetur coke
Man fetur coke samfurin mai ne mai launin toka mai duhu ko duhu, mai sheƙi mai ƙarfe kuma yana da ramuka. Yana da wani abu mai siffar granular, columnar, ko allura mai kama da carbon wanda ya ƙunshi ƙananan lu'ulu'u na graphite.
Man fetur coke ya ƙunshi hydrocarbons, 90-97% carbon, 1.5-8% hydrogen, nitrogen, chlorine, sulfur, da kuma ƙarfe masu nauyi.
Man fetur coke shine sakamakon pyrolysis na man fetur a cikin na'urar coking mai jinkiri don samar da mai mai sauƙi a zafin jiki mai yawa.
Man fetur na coke yana fitar da kusan kashi 25-30% na man fetur da aka sarrafa.
Ƙarancin ƙarfinsa yana da kusan sau 1.5-2 na kwal, yawan tokar bai wuce 0.5% ba, yawan iskar da ke cikinta yana da kusan kashi 11%, kuma ingancinsa yana kusa da anthracite.
2: Ingancin ma'aunin man fetur na coke. Coke na man fetur da aka jinkirta yana nufin coke da aka samar ta hanyar jinkirin ma'aunin coke, wanda kuma aka sani da coke na yau da kullun, babu wani ma'auni mai dacewa.
A halin yanzu, kamfanonin samar da kayayyaki na cikin gida galibi suna samarwa bisa ga ka'idar masana'antu ta SH0527-92 da tsohuwar Kamfanin Man Fetur na China ta tsara.
An rarraba ma'aunin ne bisa ga yawan sinadarin sulfur da ke cikin man fetur.
Coke mai lamba 1 ya dace da yin lantarki mai amfani da wutar lantarki ta graphite a masana'antar yin ƙarfe, kuma ana amfani da shi azaman carbon don tace aluminum
Ana amfani da coke mai lamba 2 don manna lantarki da samar da lantarki mai siffar graphite a cikin tantanin halitta na lantarki (tanda) a masana'antar narkewar aluminum
Ana amfani da coke mai lamba 3 wajen samar da silicon carbide (abin niƙa) da calcium carbide (calcium carbide), da kuma sauran kayayyakin carbon, da kuma wajen samar da tubalan anode don narkar da aluminum da kuma gina tubalan rufin carbon ko ƙasan murhu a cikin tanderun fashewa.
3: Babban AMFANI DA COKEN MAN FETUR
Babban AMFANI DA COKEN MAN FETUR sune anode da manna anode da aka riga aka gasa don aluminum na electrolytic, samar da carbon na carbonizing wakili, graphite electrode, narkar da silicon na masana'antu da mai, da sauransu.
Dangane da tsari da kuma yanayin coke na man fetur, ana iya raba kayayyakin coke na man fetur zuwa allurar coke, soso coke, projectile coke da foda coke:
(1) Coke mai siffar allura, wanda yake da tsari mai kama da allura da kuma zare, galibi ana amfani da shi azaman electrode mai ƙarfin graphite da electrode mai ƙarfin ultra-high power a cikin ƙera ƙarfe.
Saboda allurar coke tana da ƙa'idodin inganci masu tsauri a cikin abun ciki na sulfur, abun ciki na toka, abun ciki na abubuwa masu canzawa da kuma yawan gaske, akwai buƙatu na musamman akan fasahar samarwa da kayan albarkatun coke na allura.
(2) Ana amfani da sinadarin soso mai yawa a masana'antar narkar da aluminum da kuma masana'antar carbon, musamman a fannin sinadaran da ke aiki a cikin soso.
(3) Coke mai kama da robobi ko coke mai siffar ƙwallo: siffarsa mai siffar ƙwallo ce kuma diamitarsa ta kai 0.6-30mm. Galibi ana samar da shi ne daga ragowar sulfur mai yawan sulfur da kuma yawan asphaltene kuma ana iya amfani da shi ne kawai don samar da wutar lantarki, siminti da sauran man fetur na masana'antu.
(4) Coke na foda: ana samar da shi ta hanyar tsarin coke mai ruwa-ruwa tare da ƙananan barbashi (diamita: 0.1-0.4mm), yawan volatilization mai yawa da kuma yawan faɗaɗa zafi mai yawa, don haka ba za a iya amfani da shi kai tsaye a cikin shirye-shiryen lantarki da masana'antar carbon ba.
4: Coke mai da aka yi da man fetur
Idan aka yi amfani da na'urar lantarki ta graphite don yin ƙarfe ko kuma man shafawa na anode (narkewar lantarki) don aluminum da magnesium, domin a sa man fetur coke (coke) ya cika buƙatun, dole ne a yi amfani da calcined na coke ɗin.
Zafin calcining gabaɗaya yana kusa da 1300℃, manufarsa ita ce kawar da volatilization na naphthol coke gwargwadon iko.
Ta wannan hanyar, za a iya rage yawan sinadarin hydrogen da ke cikin sinadarin petroleum coke, za a iya inganta matakin graphitization na petroleum coke, za a iya inganta ƙarfin zafin jiki da juriyar zafi na graphite electrode, sannan kuma za a iya inganta ikon wutar lantarki na graphite electrode.
Ana amfani da Calcining galibi wajen samar da electrode na graphite, kayayyakin man shafawa na carbon, yashi mai siffar lu'u-lu'u, masana'antar phosphorus ta abinci, masana'antar ƙarfe da kuma sinadarin calcium carbide, daga cikinsu ana amfani da electrode na graphite sosai.
Ana iya amfani da Coke ba tare da ƙirƙira ba kai tsaye a matsayin sinadarin calcium carbide, silicon carbide da boron carbide a matsayin kayan niƙa.
Hakanan za'a iya amfani da shi kai tsaye azaman coke don murhun ƙarfe na masana'antar fashewa ko rufin murhun ƙarfe, tubalin carbon kuma ana iya amfani da shi don aiwatar da simintin ƙarfe mai ƙarfi, da sauransu.
