I-arhente ye-carburizing, isetyenziswa kwishishini lentsimbi kunye ne-casting, kwi-carburizing, desulfurization kunye nezinye izinto ezincedisayo. Eyona isetyenziswa kakhulu kwishishini lokunyibilikisa isinyithi kunye nentsimbi kukubuyisela umxholo wekhabhoni otshisiweyo kwinkqubo yokunyibilikisa isinyithi kunye nentsimbi kunye nokongezwa kwezinto ezinekhabhoni.
Kwinkqubo yokunyibilikisa imveliso yentsimbi nentsimbi, rhoqo ngenxa yexesha lokunyibilikisa, ixesha lokubamba, ixesha lokutshisa kakhulu kunye nezinye izinto, ukulahleka kokunyibilikisa kwezinto zekhabhoni kwintsimbi engamanzi kuyanda, okubangela ukwehla komxholo wekhabhoni kwintsimbi engamanzi, okubangela ukuba umxholo wekhabhoni kwintsimbi engamanzi ungafikeleli kwixabiso elilindelekileyo lokucocwa. Ke ngoko, kuyimfuneko ukongeza iimveliso zekhabhoni ukuze kulungiswe umxholo wekhabhoni wentsimbi, olulongezo oluyimfuneko ekuvelisweni kwentsimbi esemgangathweni ophezulu.
I-arhente ye-carburizing ngokwemveliso yezinto ezikrwada ingahlulwa ibe: i-carbon yomthi, i-carbon yamalahle, i-coke carbon, i-graphite.
1. Ikhabhoni yomthi
2. Uhlobo lwekhabhoni yamalahle
* I-carburizer yamalahle e-calcining eqhelekileyo: Yimveliso ye-anthracite yokuhlamba ethambileyo yomlotha ophantsi kunye ne-sulfur ephantsi kwi-calcination furnace emva kwe-calcination yobushushu obuphezulu obumalunga ne-1250℃, eveliswa kakhulu eNingxia, e-Inner Mongolia. Umxholo wekhabhoni ngokubanzi yi-90-93%. Isetyenziswa kakhulu kumashishini okwenza intsimbi, kwaye amanye amashishini okusika asetyenziswa kwi-grey cast iron. Ngenxa yesakhiwo esincinci seemolekyuli zayo zekhabhoni, inkqubo yokufunxa ubushushu iyacotha kwaye ixesha lide.
* I-asphalt coking carburizer: imveliso ephuma kwi-hydrogenation ye-coal tar ukuze kuveliswe ioyile. Yi-carburizer ene-carbon ephezulu, i-sulfur ephantsi kunye ne-nitrogen ephantsi ekhutshwe kwi-tar. Umxholo we-carbon uphakathi kwe-96-99.5%, umxholo we-volatique uphantsi, isakhiwo sixinene, amandla oomatshini kunye nokumelana nokuguguleka kwamasuntswana aphezulu, i-graphitization elula.
* I-Metallurgical coke carburizing agent: i-coking coating coating, idla ngokuba yi-cupola ene-coke enkulu, ukongeza ekunyibilikiseni, kodwa ikwasetyenziselwa i-metal charge carburizing.
3. Ikhabhoni yeCoke (i-petroleum coke)
* I-carburizer ye-coke ekhalisiweyo: Yimveliso eyenziwe nge-coke ye-petroleum e-sulfur ephantsi njengezinto eziluhlaza, ecutshungulwa kwisithando se-calcination kwi-1300-1500 degrees emva kokususa umswakama, ii-volatiles kunye nokungcola. Umxholo wayo wekhabhoni ozinzileyo ngokubanzi uzinzile malunga ne-98.5%, kwaye umxholo wayo wesalfure uninzi lwawo ungaphantsi kwe-0.5% okanye i-1%. Uxinano lwayo luncinci, alulula ukubola, kwaye ixesha lokusetyenziswa kwayo liphakathi. Imveliso igxile kakhulu eShandong, eLiaoning, eTianjin. Ngenxa yexabiso layo kunye nobonelelo kwiindidi ezininzi ze-carburizing agent inenzuzo, imakethi isetyenziswa kakhulu.
* I-graphitic petroleum coke carburizing agent: i-petroleum coke kwisithando sokunyibilikisa i-graphitic emva kokuveliswa kwee-degrees ezingama-3000 zobushushu obuphezulu kweemveliso ze-graphitic, kunye nokufunxwa ngokukhawuleza, iingenelo ze-carbon ephezulu kunye ne-sulfur ephantsi. Umxholo wayo we-carbon yi-98-99%, isalathisi somxholo we-sulfur singaphantsi kwe-0.05% okanye i-0.03%, iindawo ezivelisa zigxile kwi-Inner Mongolia, eJiangsu, eSichuan njalo njalo. Enye indlela ivela kwi-graphite electrode yokusika inkunkuma, kuba i-graphite electrode ngokwayo emva konyango lwe-graphitization, inkunkuma ingasetyenziswa njenge-carburizing agent yee-mills zentsimbi.
* I-semi-graphitic petroleum coke carburizer: ubushushu be-graphitic abuphezulu njenge-graphitic carburizer, umxholo we-carbon ngokubanzi ungaphezulu kwe-99.5, umxholo wesalfure uphezulu kune-graphitic carburizer, ungaphantsi kwe-0.3%.
4. Uhlobo lweGraphite
* I-arhente ye-carburizing efana ne-graphite yomhlaba: kukusetyenziswa kwe-graphite efana ne-earth-like kwi-iron and steel smelting okanye i-casting carburizing, eyona ndawo iphambili eHunan, kukusetyenziswa ngokuthe ngqo kwe-graphite efana ne-earth-like powder, ngokuqhelekileyo umxholo we-carbon kwi-75-80%, inokucocwa ukuze kwandiswe umxholo we-carbon wemveliso.
* I-arhente ye-carburizing ye-graphite yendalo: ikakhulu i-grafayithi eqhekekayo, umxholo wekhabhoni kwi-65-99%, uzinzo oluphantsi, olusetyenziswa ngokubanzi kwiimililo zentsimbi.
* I-composite carburizing agent: umgubo wegrafiti, umgubo wecoke, i-petroleum coke kunye nezinye izinto ezisetyenziswa emilenzeni, ukongeza izinto ezahlukeneyo zokubopha kunye nomatshini kunokucinezelwa kwimo, ukuze intonga ibe yigranular. Umxholo wekhabhoni ngokubanzi uphakathi kwe-93 kunye ne-97%, kwaye umxholo wesalfure awuzinzanga kakhulu, ngokubanzi uphakathi kwe-0.09 kunye ne-0.7.
