Icoke yepetroleum enegraphitisisidibaniso sekhabhoni esinegrafiti esisetyenziswa ngesixhobo esitsha kunye nesisebenzayo sekhabhoni kwishishini lesinyithi, isithando somlilo okanye i-oven (ladle).Ukusebenza kwinkqubo yokwenza intsimbi, kunokunciphisa umxholo wekhabhoni kwintsimbi ukuze ufumane isinyithi esinyibilikisiweyo esifanelekileyo, ngokusebenzisa izixhobo zekhabhoni ngeendlela ezahlukeneyo, njenge-carburizing agent edla ngokusetyenziswa icoke metallurgical, i-petroleum coke yongezwa phantsi kwe-asphalt yerabha ephantsi. , ikhabhoni ye-calcined, kuba ezi zixhobo ziyizinga eliphantsi lokufunxa, umxholo wesulfure ephezulu, Okwangoku kunzima ukuqinisekisa ukuzinza komgangatho wensimbi ofunekayo kwiinkqubo eziphezulu zensimbi.

　　Kujoliswe kubathengi

Ukunyibilika kwentsimbi kunye nentsimbi, ukuphosa, umthengisi ophakathi.

Ubume bomzimba

Ukubonakala okucocekileyo, akukho kungcola, ukufana kwe-particle size (malunga ne-1.5MM), inokuvela kubathengi abaninzi iminyaka emininzi yamava, ingaphantsi kweetoni ezi-5 zokusetyenziswa kwesithando somlilo esiphakathi, izinga lokufunxa amanzi, izinga lokufunxa;Ifom: Umgangatho wekristale, ibakala lentsimbi ephosiweyo kunye nokuphucula ngokufanelekileyo iipropati zekhabhoni ephezulu esisigxina, ukufunxa, isulfure ephantsi, i-nitrogen, kwaye ngokukhawuleza kune-agent yekhabhoni efana ne-graphitized kwizinga lokufunxa, i-adsorption furnace eludongeni lokufunxa okungaphelelanga ngaphandle kwentsalela, ixabiso lingaphantsi kwexabiso. efanayo sulfur graphitized carbon additives ngaphantsi kwe-0.05, kunye nokusebenza okuphantsi kweendleko.

Uhlalutyo lwemichiza

Izinga lokufunxa, usebenzisa izinga eliphezulu lokufunxa linokufikelela kwi-95% ngokutsho.Isantya sokufunxa siyakhawuleza, sikhawuleza kunesantya esifanayo sokufunxa se-graphitization carburizing agent, akukho ludonga lwesithando se-adsorption, kwaye akukho ntsalela, iadvanteji yesantya sokufunxa se-carburizing ibonakala ngakumbi.I-nitrogen ephantsi isulfure, i-0.03% okanye ngaphantsi, ixabiso eliphezulu, kwii-agent ze-graphitizing ezifanayo (i-sulfur ≦0.05) inzuzo engcono kakhulu yexabiso lekhabhoni ehlaziyiweyo ngasentla.

Impembelelo yenzuzo

I-agent ye-graphite carburizingukuze unciphise iindleko, uphucule umgangatho wemveliso.Izinto eziluhlaza zinokunyusa inani lentsimbi ye-scrap, ukunciphisa inani lentsimbi yehagu okanye akukho ntsimbi, ukuphepha ngokufanelekileyo umphumo we-iron castings.I-sulfure ephantsi, iibhola zesulfure zithembekile, zikhuselwe ngokufanelekileyo kunye ne-alloy, i-alloy igcina iindleko kwimiphumo emibi yokuzala.Ngenxa yeqondo eliphantsi lokunyibilika, isantya sokufunxa, akukho slag, inokukhusela ngokufanelekileyo kwaye yandise ubomi beziko, inciphise ukusetyenziswa kwe-lining, ukwakheka kweekhemikhali ezicocekileyo: i-carbon, isulfure, i-nitrogen micro, iimveliso ezizinzile ukungcola okuncinci okuyingozi, isiphumo se-carburizing izinzile, isiphumo esihle sokufunxa, umphumo wobushushu uyabonakala, akukho kubuyiselwa kwe-slag.
