Kwinkqubo yokunyibilikisa, ngenxa ye-dosing engafanelekanga okanye ukutshaja kunye ne-decarbonization egqithisileyo kunye nezinye izizathu, ngamanye amaxesha umxholo wekhabhoni kwintsimbi okanye isinyithi awuhambisani neemfuno ezilindelekileyo, ngoko ke kuyimfuneko ukutshisa isinyithi okanye isinyithi se-liquid.Ezona zinto ziqhele ukusetyenziselwa i-carburizing ngumgubo we-anthracite, i-carburized pig iron, i-electrode powder, i-petroleum coke powder, i-asphalt coke, i-charcoal powder kunye ne-coke powder.Iimfuno ze-carburizer kukuba iphezulu i-carbon content content, ingcono, kwaye iyancipha umxholo wokungcola okuyingozi njengothuthu, into eguqukayo kunye nesulfure, ingcono, ukuze ingangcolisi intsimbi.
Ukunyibilikiswa kwe-castings kusebenzisa i-recarburizer ekumgangatho ophezulu emva kokutshiswa kobushushu obuphezulu be-petroleum coke enobumdaka obumbalwa, elona khonkco libalulekileyo kwinkqubo yokungcwatywa kwe-carburizing.Umgangatho we-recarburizer umisela umgangatho we-iron engamanzi, kwaye kwakhona unquma ukuba umphumo we-graphitization unokufumaneka.Ngamafutshane, ukunciphisa i-iron shrinkage recarburizer idlala indima ebalulekileyo.
Xa zonke iintsimbi ezilahliweyo zinyibilikiswa kwiziko lombane, i-recarburizer eyenziwe igraphiti iyathandwa, kwaye i-recarburizer efakwe igraphiti kubushushu obuphezulu inokutshintsha iiathom zekhabhoni ukusuka kulungiselelo lwangaphambili lokuphazamiseka ukuya kulungiselelo lwamaphepha, kwaye iphepha legraphite linokuba lelona lilungileyo. undoqo wegraphite nucleation ukukhuthaza igraphitization.Ngoko ke, kufuneka sikhethe i-recarburizer ephathwe nge-graphitization yobushushu obuphezulu.Ngenxa yonyango oluphezulu lwe-graphitization yokushisa, umxholo wesulfure ukhiqizwa i-SO2 yegesi yokuphunyuka kunye nokunciphisa.Ke ngoko, umxholo wesulfure we-recarburizer ekumgangatho ophezulu uphantsi kakhulu, ngokubanzi ungaphantsi kwe-0.05%, kwaye ungcono ungaphantsi kwe-0.03%.Ngexesha elifanayo, oku kukwasalathiso esingathanga ngqo sokuba ngaba iphathwe nge-graphitization yokushisa okuphezulu kunye nokuba i-graphitization ilungile.Ukuba i-recarburizer ekhethiweyo ayinayo i-graphitized kwiqondo lokushisa eliphezulu, amandla e-nucleation ye-graphite ayancipha kakhulu, kwaye amandla e-graphitization ayancipha, nokuba umlinganiselo ofanayo wekhabhoni unokufumaneka, kodwa iziphumo zihluke ngokupheleleyo.
Into ebizwa ngokuba yi-recarburizer kukwandisa ngokufanelekileyo umxholo wekhabhoni kwintsimbi yolwelo emva kokongeza, ngoko umxholo wekhabhoni esisigxina ye-recarburizer kufuneka ungabi phantsi kakhulu, kungenjalo ukufezekisa umxholo othile wekhabhoni, kufuneka ungeze iimveliso ezingaphezulu kuneziphakamileyo. -ikhabhoni recarburizer, ngokungathandabuzekiyo yonyusa inani lezinye izinto ezingathandekiyo kwi-carburizer, ukuze i-iron engamanzi ingakwazi ukufumana imbuyekezo engcono.
I-sulphur ephantsi, i-nitrogen kunye ne-hydrogen elements zingundoqo zokuthintela ukuveliswa kwe-nitrogen pores kwi-castings, ngoko umxholo we-nitrogen we-recarburizer kufuneka ube ngaphantsi kangangoko kunokwenzeka.
Ezinye izalathisi ze-recarburizer, ezinje ngobungakanani bokufuma, uthuthu, ukuguquguquka, ukuthoba isixa sekhabhoni esisigxina, ukuphakama kwekhabhoni esisigxina, ngoko ke isixa esikhulu sekhabhoni engatshintshiyo, umxholo wala malungu anobungozi akufunekanga phezulu.
Kwiindlela ezahlukeneyo zokunyibilika, iintlobo zesithando somlilo kunye nobukhulu beziko lokunyibilika, kubalulekile ukuba ukhethe ubungakanani besuntswana le-recarburizer elichanekileyo, elinokuphucula ngokufanelekileyo isantya sokufunxa kunye nesantya sokufunxa kwe-recarburizer kwintsimbi engamanzi, kwaye unqande i-oxidation kunye ne-oxidation. ilahleko evuthayo ye-carburizer ebangelwa yisayizi encinci kakhulu.Ubungakanani bayo be-particle bungcono kakhulu: i-100kg i-furnace ingaphantsi kwe-10mm, i-500kg i-furnace ingaphantsi kwe-15mm, i-1.5 yetoni yomlilo ingaphantsi kwe-20mm, i-20 yetoni yomlilo ingaphantsi kwe-30mm.Kwi-converter smelting, xa kusetyenziswa i-carbon steel high, i-recarburizer equkethe ukungcola okumbalwa isetyenziswa.Iimfuno ze-recarburizer esetyenziswe kwi-top blown converter steelmaking yikhabhoni ephezulu esisigxina, umxholo ophantsi womlotha, oguquguqukayo kunye nesulfure, i-phosphorus, i-nitrogen kunye nezinye izinto ezingcolileyo, kunye nobukhulu bomileyo, obucocekileyo, obuphakathi.Ikhabhoni yayo emiselweyo C≥96%, umxholo oguquguqukayo ≤1.0%, S≤0.5%, umswakama ≤0.5%, ubukhulu be-particle kwi-1-5mm.Ukuba ubungakanani bamasuntswana buhle kakhulu, kulula ukutshisa, kwaye ukuba bunzima kakhulu, buhamba phezu komgangatho wentsimbi engamanzi kwaye akulula ukufunxwa yintsimbi etyhidiweyo.Kwi-particle ye-furnace induction particle kwi-0.2-6mm, apho intsimbi kunye nezinye i-particle yensimbi emnyama kwi-1.4-9.5mm, i-carbon steel high idinga i-nitrogen ephantsi, ubukhulu be-particle kwi-0.5-5mm njalo njalo.Imfuno ethile ngokohlobo oluthile lweziko lokunyibilikisa uhlobo lomsebenzi kunye nezinye iinkcukacha ezithile isigwebo kunye nokukhetha.
