I-agent ye-Carburizing, isetyenziselwa kwi-iron kunye ne-casting industry, i-carburizing, i-desulfurization kunye nezinye izinto ezincedisayo. Eyona nto isetyenziswa kakhulu kwi-iron kunye ne-smelting industry kukwenza umxholo wekhabhoni otshiswe kwinkqubo yokunyibilika kwentsimbi kunye nokongeza izinto ezinekhabhoni.
Kwinkqubo yokunyibilikisa isinyithi kunye neemveliso zentsimbi, ngokufuthi ngenxa yexesha lokunyibilikisa, ukubamba ixesha, ixesha lokufudumeza ngokugqithiseleyo kunye nezinye izinto, ukunyibilika kwelahleko yezinto zekhabhoni kwintsimbi engamanzi kuyanda, okukhokelela ekuncipheni komxholo wekhabhoni wentsimbi engamanzi, okukhokelela ekubeni Umxholo wekhabhoni wentsimbi engamanzi awukwazi ukufikelela kwixabiso lethiyori elilindelekileyo lokucokisa. Ngoko ke, kuyimfuneko yokongeza iimveliso ze-carburizing ukulungelelanisa umxholo wekhabhoni yensimbi, eyona nto ibalulekileyo eyongezelelweyo yokuncedisa ukuveliswa kwensimbi ephezulu.
Carburizing agent ngokokuveliswa kwemathiriyeli ekrwada inokwahlulwa ibe: ikhabhoni yomthi, ikhabhoni yamalahle, icoke carbon, igraphite.
1. Ikhabhoni yokhuni
2. Uhlobo lwamalahle lwekhabhoni
* I-calcining ye-carburizer yamalahle ngokubanzi: Yimveliso yothuthu oluphantsi kunye ne-anthracite ephantsi yesulfure ecocekileyo kwi-calcination calcination emva kwe-1250 ℃ ubushushu obuphezulu bokubala, iveliswa ikakhulu e-Ningxia, e-Inner Mongolia. Umxholo wekhabhoni jikelele ngu-90-93%. Isetyenziswa ikakhulu kumashishini okwenza intsimbi, kwaye amanye amashishini okugalela asetyenziswa kwintsimbi engwevu. Ngenxa yesakhiwo esihlangeneyo seemolekyuli zekhabhoni, inkqubo yokufunxa ubushushu iyacotha kwaye ixesha lide.
* I-asphalt coking carburizer: imveliso yetha yamalahle e-hydrogenation ukuvelisa i-oyile. Yikhabhoni ephezulu, isulfure ephantsi kunye ne-nitrogen ephantsi ye-carburizer ekhutshwe kwi-tar. Umxholo wekhabhoni uphakathi kwe-96-99.5%, umxholo oguquguqukayo uphantsi, isakhiwo sinobunzima, amandla omatshini kunye nokuxhatshazwa kokugqoka amaqhekeza aphezulu, kulula i-graphitization.
• I-Metallurgical coke carburizing agent: ukuqhunyiswa kwamalahle, idla ngokuba yicupola enecoke enkulu, ukongeza ekunyibilikeni, kodwa ikwasetyenziselwa ukuhlawula intsimbi.
3. Icoke (petroleum coke) ikhabhoni
* I-coke carburizer ene-calcined: Yimveliso eyenziwe nge-coke ye-petroleum ephantsi-sulphur njengempahla eluhlaza, ecutshungulwa kwisithando somlilo kwi-1300-1500 degrees emva kokususa umswakama, ukuguquka kunye nokungcola. Umxholo wayo wekhabhoni osisigxina uzinzile ngokubanzi malunga ne-98.5%, kwaye umxholo wayo wesulfure ungaphantsi kwe-0.5% okanye i-1%. Ubuninzi bayo bubumbene, akukho lula ukubola, kwaye ixesha lokusetyenziswa kwalo liphakathi. Imveliso igxile kakhulu eShandong, eLiaoning, eTianjin. Ngenxa yexabiso layo kunye nokubonelela kwiindidi ezininzi ze-arhente ye-carburizing inenzuzo, imarike isetyenziswa ngokubanzi.
* I-Graphitic petroleum coke carburizing agent: i-petroleum coke kwi-graphitic smelting furnace emva kwee-degrees ezingama-3000 zokuvelisa ubushushu obuphezulu beemveliso zegraphic, kunye nokufunxa okukhawulezayo, i-carbon ephezulu kunye neenzuzo eziphantsi zesulfure. Umxholo wayo wekhabhoni ngu-98-99%, isalathisi somxholo wesulfure singaphantsi kwe-0.05% okanye i-0.03%, iindawo zokuvelisa zigxininiswe kwi-Inner Mongolia, i-Jiangsu, iSichuan njalonjalo. Enye indlela ivela kwi-graphite electrode yokusika inkunkuma, kuba i-electrode yegraphite ngokwayo emva konyango lwe-graphitization, inkunkuma ingasetyenziselwa njenge-carburizing agent ye-steel mills.
* I-semi-graphitic petroleum coke carburizer: iqondo lobushushu begraphic alikho phezulu njenge-graphitic carburizer, umxholo wekhabhoni ungaphezulu kwe-99.5, umxholo wesulfure uphezulu kune-graphitic carburizer, ngaphantsi kwe-0.3%.
4. Uhlobo lwegraphite
* I-ejenti efana ne-graphite carburizing agent: kukusetyenziswa kwegraphite enjengomhlaba kwintsimbi kunye nokunyibilika kwentsimbi okanye ukuphosa i-carburizing, indawo yayo ephambili yokuvelisa e-Hunan, kukusetyenziswa ngokuthe ngqo kwe-graphite powder yomhlaba, ngokuqhelekileyo umxholo wekhabhoni kwi-75-80 %, inokuhlanjululwa ukwandisa umxholo wekhabhoni yemveliso.
* I-agent ye-carburizing yendalo ye-graphite: ngokukodwa kwi-flake graphite, umxholo wekhabhoni kwi-65-99%, ukuzinza okuphantsi, ngokuqhelekileyo kusetyenziswe kwiintsimbi zetsimbi.
* I-arhente ye-carburizing edibeneyo: umgubo wegraphite, umgubo wecoke, i-petroleum coke kunye nezinye izinto zeenyawo, ukongeza izibophelelo ezahlukeneyo ngomatshini unokucinezelwa kwimilo, kwi-rod granular. Umxholo wekhabhoni uphakathi kwe-93 kunye ne-97%, kwaye umxholo wesulfure uzinzile kakhulu, ngokubanzi phakathi kwe-0.09 kunye ne-0.7.
