Recarburizerukwenza intsimbi kunye ne-recarburizer (umgangatho wemveliso yesinyithi yesinyithi yeRiphabhlikhi yaBantu baseTshayina, YB / T 192-2001 yokwenza intsimbi kunye ne-recarburizer) kunye nentsimbi ephoswe nge-recarburizer, kunye nezinye izinto ezongeziweyo zikwaluncedo ukuphinda kufakwe i-recarburizer, njenge-brake pad enezongezo, njengezinto ezixubeneyo.I-Recarburizer yeyokwenziwa kwentsimbi yangaphandle, ukwenza i-ironmaking recarburizer ekrwada.I-recarburizer ekumgangatho ophezulu sisongezo esincedisayo esiyimfuneko ekuvelisweni kwentsimbi ekumgangatho ophezulu.

Ukusetyenziswa kwe-carbon agent:

Kwinkqubo yokunyibilikisa, ngenxa ye-batching engafanelekanga okanye ukutshaja kunye ne-decarburization egqithisileyo kunye nezinye izizathu, ngamanye amaxesha okubangelwa kwisiqulatho sekhabhoni yentsimbi ayizange ihlangabezane neemfuno zexesha eliphakamileyo, emva koko kwi-carburization ye-liquid steel. umgubo, i-petroleum coke powder, i-charcoal powder kunye ne-coke powder.I-Converter medium smelting medium and high carbon steel, ukusetyenziswa kwe-petroleum coke equlethe ukungcola okumbalwa njenge-carburizing agent.Iimfuno ze-recarburizer ye-top blown converter i-steelmaking yi-carbon ephezulu esisigxina, umxholo ophantsi wothuthu. , i-volatile, isulfure, i-phosphorus, i-nitrogen kunye nezinye izinto ezingcolileyo, zomile, zicocekile kwaye ziphakathi.

Iqela lekhabhoni esisigxina lahlulwe ngokwe:

w (C)> 96%, into eguqukayo ≤1.0%, W (S) ≤0.5%, W (umswakama)≤0.55%, ubukhulu be-particle ye-1 ukuya kwi-5mm.

Ukuba ubungakanani besuntswana buhle kakhulu, kulula ukutshisa.Ukuba i-coarse kakhulu, idada phezu kwentsimbi etyhidiweyo kwaye akulula ukuba ifunnwe yintsimbi etyhidiweyo.Ubukhulu be-particle ye-furnace induction kwi-0.2-6mm, intsimbi kunye nobunye ubungakanani bentsimbi emnyama kwi-1.4-9.5mm , intsimbi yekhabhoni ephezulu ifuna initrogen ephantsi, ubungakanani besuntswana kwi-0.5-5mm, kwaye njalo kwimfuno ethile ngokwendlela ethile yokunyibilikisa isithando somlilo kunye neenkcukacha zesigwebo esithile kunye nokukhetha.

1, indlela yokufaka iziko:

I-Recarburizer ifanelekile ukunyibilika kwisithando somlilo se-induction, kodwa ukusetyenziswa okuthe ngqo akufani ngokuhambelana neemfuno zenkqubo.

(1) ukusetyenziswa kwe-recarburizer kwi-medium frequency frequency smelting kwiziko lombane, ngokomlinganiselo okanye iimfuno ezilinganayo zekhabhoni kunye nezinto ezongeziweyo kwindawo engezantsi yesithando sombane, izinga lokubuyisela linokufikelela ngaphezu kwama-95%;

(2) ukuba ukungabikho kolungelelwaniso lwekhabhoni, ishumi elinesibini lokuqala le-slag yesithando somlilo, kunye ne-carburant, ngokunyusa ubushushu bentsimbi etyhidiweyo, okanye ukuxhokonxa kwe-electromagnetic okunyibilikisa ukunyibilikisa ukufunxa kwekhabhoni, inqanaba lokubuyisela lijikeleze i-90%, ukuba ubushushu obuphantsi. Inkqubo ye-carbonization, intlawulo yesithando sokunyibilika iyinxalenye kuphela yolwelo lwentsimbi enyibilikisiweyo phantsi kwemeko yobushushu obuphantsi, yonke i-recarburizer ngexesha elinye kwi-iron engamanzi, kwangaxeshanye, icinezelwe kwintsimbi etyhidiweyo ngentlawulo eqinileyo ukuze kungabikho. veza ubuso bentsimbi etyhidiweyo.Ngale ndlela, i-carburization yentsimbi engamanzi inokufikelela ngaphezu kwe-1.0%.

2, ngaphandle kwesithando somlilo:

(1) fafaza umgubo wegraphite engxoweni

Ukusebenzisa i-graphite powder njenge-recarburizer, umthamo wenaliti yi-40kg / t, kwaye umxholo wekhabhoni yentsimbi engamanzi kulindeleke ukuba unyuke ukusuka kwi-2% ukuya kwi-3%.Ubushushu bentsimbi enyibilikisiweyo phambi kwe-carburization yayiyi-1600 ℃, kunye nobushushu obuphakathi emva kokutshatyalaliswa kwe-carburization. I-1299 ℃.I-Jet graphite powder carburization, ngokuqhelekileyo isebenzisa i-nitrogen njengomthwali, kodwa phantsi kweemeko zemveliso yezoshishino, kunye nomoya ocinezelweyo ulungele ngakumbi, kunye nokutshiswa kwe-oksijini emoyeni oxinzelelweyo ukuvelisa i-CO, ubushushu bokusabela kweekhemikhali bunokubuyisela inxalenye yokuhla kweqondo lokushisa, kunye ne-CO yokunciphisa umoya wokuphucula umphumo we-carburization.

(2) ukusetyenziswa kwe-recarburizer xa intsimbi

Iinjongo ze-100-300 ze-graphite powder carburizer zingafakwa engxoweni, okanye kwitanki yentsimbi kunye nokugeleza, emva kokuba ulwelo lwentsimbi lushukunyiswe ngokupheleleyo, kangangoko kunokwenzeka ukunyibilikisa ukufunxwa kwekhabhoni, izinga lokubuyiselwa kwekhabhoni limalunga nama-50% .

Isetyenziselwa ukuphosa, intsimbi, intsimbi, intsimbi iya kuba nemfuneko yekhabhoni, i-carburant njengoko igama layo libonisa ukunyusa umxholo wekhabhoni kwintsimbi engamanzi, kwaye, umzekelo, isetyenziselwa ukunyibilikisa intlawulo yesithando sehagu, i-scrap. intsimbi, ibuyele kwintlawulo yesithando somlilo, isiqulatho sekhabhoni yentsimbi siphezulu, kodwa ixabiso lokuthengwa kwezinto ezilahliweyo liphezulu, ngoko ke ukonyusa unikezelo lwe-scrap, ukwehlisa ubungakanani bentsimbi etyhidiweyo, ukongezwa kwe-recarburizer kunokunciphisa iindleko zokuphosa ukuya kwinqanaba elithile.
