Mokhoa oa ho khetha recarburizer ea boleng bo holimo ea ho etsa tšepe
Ts'ebetsong ea ho qhibiliha, ka lebaka la ho kopanya kapa ho tjhaja ka mokhoa o sa lokelang le ho senya ka mokhoa o feteletseng, ka linako tse ling carbon content ka tšepe kapa tšepe ha e finyelle litlhoko tse lebeletsoeng.Ka nako ena, carbon e lokela ho ekeletsoa ka tšepe kapa tšepe e qhibilihisitsoeng.Lisebelisoa tse ka sehloohong tse atisang ho sebelisoa bakeng sa carbonization ke phofo ea anthracite, tšepe ea kolobe e nang le carbonized, electrode powder, petroleum coke powder, pitch coke, charcoal powder le coke powder.Litlhoko tsa li-recarburizers ke hore ha ho na le carbon content e tsitsitseng, ho molemo, le ho theola lintho tse litšila tse kotsi tse kang molora, ntho e sa tsitsang le sebabole, e molemo, e le hore e se ke ea silafatsa tšepe.
Ho qhibiliha ha li-castings ho sebelisa li-recarburizers tsa boleng bo holimo ka mor'a ho baloa ha mocheso o phahameng oa petroleum coke e nang le litšila tse fokolang, e leng sehokelo sa bohlokoahali ts'ebetsong ea recarburization.Boleng ba recarburizer bo lekanya boleng ba tšepe e qhibilihisitsoeng, hape bo etsa qeto ea hore na phello e ntle ea graphitization e ka fumanoa.Ka bokhutšoanyane, ho fokotsa ho honyela ha tšepe e qhibilihisitsoeng le li-recarburizers li bapala karolo ea bohlokoa.
Ha tšepe kaofela e qhibilihisoa ka sebōping sa motlakase, ho khethoa recarburizer ea graphitized.Ka mor'a phekolo e phahameng ea mocheso oa graphitization, liathomo tsa carbon li ka fetoha ho tloha tlhophisong ea pele e sa sebetseng ho ea ho tlhophiso ea flake, 'me graphite ea flake e ka fetoha graphite.Molemo ka ho fetisisa oa mantlha oa mantlha, e le ho bebofatsa ts'ebetso ea graphitization.Ka hona, re lokela ho khetha recarburizer e entsoeng ka graphitization ea mocheso o phahameng.Ka lebaka la phekolo e phahameng ea mocheso oa graphitization, sebabole se fokotseha ka ho baleha ha khase ea SO2.Ka hona, li-recarburizer tsa boleng bo holimo li na le lintho tse tlase haholo tsa sebabole, w(s) hangata e ka tlase ho 0.05%, mme w(s) e betere e ka tlase ho 0.03%.Ka nako e ts'oanang, sena e boetse ke pontšo e sa tobang ho ahlola hore na e bile le phekolo e phahameng ea mocheso oa graphitization le hore na graphitization e ntle.Haeba recarburizer e khethiloeng e e-s'o fumane phekolo ea mocheso o phahameng oa graphitization, bokhoni ba nucleation ea graphite bo tla fokotseha haholo, 'me bokhoni ba graphitization bo tla fokola.Esita le haeba tekanyo e lekanang ea carbon e ka finyelloa, liphello li fapane ka ho feletseng.
