Tšebeliso ea li-recarburizer tsa petroleum coke tsa boleng bo holimo tse nang le graphitized li ka tlisetsa likhoebo melemo e felletseng ea moruo likarolong tse ngata, ho kenyeletsoa ho fokotsa litšenyehelo tsa tlhahiso, ho ntlafatsa boleng ba sehlahisoa, ho ntlafatsa katleho ea tlhahiso le ho ntlafatsa melemo ea tšireletso ea tikoloho. Tlhahlobo e ikhethileng ke e latelang:
I. Ho Fokotsa Litšenyehelo tsa Tlhahiso le ho Ntlafatsa Tšebeliso ea Thepa
Ho Fokotsa Tšebeliso ea Tšepe ea Kolobe: Li-recarburizer tsa petroleum coke tsa boleng bo holimo tse nang le graphitized, tse khetholloang ka dikahare tse phahameng tsa khabone e tsitsitseng (hangata ≥98%) le litšila tse tlase, li ka nkela mohloli oa khabone sebaka ka katleho tšepeng ea kolobe. Ho ea ka lintlha tsa indasteri, ho sebelisa recarburizer ena ho ka fokotsa tšebeliso ea tšepe ea kolobe ka 20%-40%, ho fokotsa litšenyehelo ka tonne ea li-castings ka hoo e ka bang 300-500 yuan. Mohlala, khoebo ea foundry e bolokile li-yuan tse fetang milione e le 'ngoe litšenyehelong tsa theko ea tšepe ea kolobe ka ho ntlafatsa karolelano ea recarburizer.
Ho Ntlafatsa Sekhahla sa ho Monya: Kalafo ea graphitization e nolofalletsa liathomo tsa carbon ho theha sebopeho se hlophisitsoeng ka mekhahlelo, e leng se eketsang sekhahla sa ho monya ho tloha ho 60% ea li-recarburizer tse tloaelehileng ho ea ho 90%-95%. Sena se bolela hore ho hlokahala recarburizer e nyane ho fihlela litaba tsa carbon tse reriloeng, e leng se fokotsang litšenyehelo tsa thepa. Mohlala, ho etseng tšepe ea arc oven ea motlakase, ho eketsa 0.1%-0.3% ea recarburizer e nang le graphitized ho ka fetola litaba tsa carbon ka har'a tšepe e qhibilihisitsoeng ha ka nako e khutsufatsa nako ea ho qhibilihisa ka metsotso e 15-20 le ho fokotsa tšebeliso ea matla.
II. Ho Ntlafatsa Boleng ba Sehlahisoa le ho Ntlafatsa Tlholisano ea 'Maraka
Ho Ntlafatsa Tshebetso ya ho Lahla: Dikristale tse nyane tsa graphite tse nang le di-recarburizer tsa petroleum coke tsa boleng bo hodimo di ka sebetsa e le di-nuclei tsa kristale, di kgothaletsa kgolo e tshwanang ya di-flakes tsa graphite ka hara tshepe e entsweng ka foreshe. Ka tshepe e putswa, sena se ka eketsa matla a ho thapolla ka 15%-25%; ka tshepe e ductile, se ka ntlafatsa ho ruruha ka 10%-20%. Mohlala, kamora ho fetohela ho recarburizer ena, moetsi wa diboloko tsa di-cylinder tsa enjene ya dikoloi o ile a fokotsa sekgahla sa ho lahla ho tloha ho 15% ho ya ho 3%, a ntlafatsa haholo tlhahiso ya sehlahiswa.
Ho Finyella Litlhoko tsa Maemo a Phahameng: Litšobotsi tsa sebabole se tlase (≤0.05%) le naetrojene e tlase (≤400ppm) li etsa hore li-recarburizer tsa petroleum coke tse nang le graphitized e be thepa ea bohlokoa bakeng sa ho hlahisa li-castings tsa likoloi tsa maemo a holimo, lisebelisoa tsa motlakase oa moea le likarolo tse ling tsa bohlokoa. Ho sebelisa recarburizer ena ho ka thibela liphoso tsa ho lahla tse kang mapetso le masoba a bakoang ke litšila tsa sebabole le naetrojene, ho ntlafatsa boleng ba sehlahisoa.
III. Ho Ntlafatsa Bokgoni ba Tlhahiso le ho Khutsufatsa Dipotoloho tsa Tlhahiso
Ho Eketsa Lebelo la ho Qhibilihisa: Nakong ea ho etsa tšepe, li-recarburizer tsa petroleum coke tsa boleng bo holimo tse nang le graphitized li ka qhibiliha ka potlako le ho aba ka ho lekana, li fokotsa nako ea ho qhibilihisa. Mohlala, leloala la tšepe le khutsufalitse potoloho ea lona ea ho qhibilihisa sebōpi sa motlakase ka 15%-20% kamora ho sebelisa recarburizer ena, e leng se eketsang tlhahiso ea tšepe ea selemo le selemo ka lithane tse fetang 10,000.
Ho Tsitsisa Mekhoa ea Tlhahiso: Bohloeki bo phahameng le litšila tse tlase tsa recarburizer li thibela oxidation le ho senyeha ha mocheso o phahameng, li fokotsa ho feto-fetoha ha tlhahiso. Mohlala, ho etseng ka mokhoa o tsoelang pele, ho sebelisa recarburizer ena ho ka boloka dikahare tse tsitsitseng tsa khabone ka har'a tšepe e qhibilihisitsoeng, ho qoba mathata a boleng ba ho etseng ka lebaka la ho feto-fetoha ha dikahare tsa khabone.
IV. Ho Ntlafatsa Melemo ea Tšireletso ea Tikoloho le ho Finyella Litlhoko tsa Nts'etsopele e Tšoarellang
Ho Fokotsa Mesi e Hlahisang Tshilafalo: Litšobotsi tse tlase tsa sebabole le naetrojene e tlase tsa li-recarburizer tsa petroleum coke tse nang le graphitized li fokotsa haholo mesi e hlahisang ea sulfur dioxide le nitrogen oxides nakong ea ho cha. Mohlala, kamora ho sebelisa recarburizer ena, feme ea ho theha e ile ea fokotsa litšenyehelo tsa eona tsa ho tlosa sulfurization ea khase ea flue ka 40% mme ea fokotsa mesi e hlahisang ea sulfur dioxide ea selemo le selemo ka lithane tse ngata.
Ho Khothaletsa ho Ntjhafatsa Mehlodi: Nakong ya tlhahiso ya di-recarburizer tsa petroleum coke tse nang le graphitized, mocheso o lahlilweng o ka fumanwa bakeng sa tlhahiso ya motlakase, ho boloka 300 kWh ya motlakase ka tonne ya sehlahiswa. Ho feta moo, kgase ya mohatla e ka fanwa makaleng a mang a diindasteri (jwalo ka dimela tsa ceramic) e le mafura, ho fihlella tshebediso e sebetsang hantle ya mehlodi. Mohlala, ka mohlala wa moruo o chitja, serapa sa diindasteri tsa tikoloho se fokoditse mesi ya khabone ka ditone tse 1.2 ka tonne ya recarburizer e hlahisitsweng.
