Iicarburizers zohlulwe zibe: i-petroleum coke carburizers, i-graphitized carburizers, i-graphite carburizers yendalo, i-metallurgical coke carburizers, i-calcined carburizers yamalahle, i-graphite carburizers yendalo, kunye ne-composite material carburizers.

Owona mahluko uphambili phakathi kwegraphite recarburizers kunye namalahle recarburizers zezi:

1. Iimathiriyeli ekrwada zahlukile.I-Graphite recarburizer icutshungulwa ngokujonga igraphite yendalo, ngelixa i-recarburizer yamalahle ibalwa kwi-anthracite;

Okwesibini, iimpawu ziyahluka.I-Graphite recarburizer ineenzuzo zesulfure ephantsi kunye ne-nitrogen, ukumelana nokushisa okuphezulu, ukuhanjiswa kombane okulungileyo, njl., ezingafumanekiyo kwi-recarburizers esekelwe kumalahle;

Isithathu, izinga lokufunxa lahlukile.Izinga lokufunxa i-graphite recarburizer linokufikelela ngaphezulu kwe-90%, ngoko ke nokuba umxholo wekhabhoni we-graphite recarburizer awuphezulu, unokuhlangabezana neemfuno zokusetyenziswa;

Okwesine, iindleko zahlukile.Nangona ixabiso le-graphite recarburizer liphezulu, ixabiso elibanzi lokusetyenziswa liphantsi kakhulu.

I-carburization ye-carburizer iqhutyelwa ngokuchithwa kunye nokusabalalisa kwekhabhoni kwintsimbi etyhidiweyo.Uphando lubonise ukuba xa umxholo wekhabhoni we-iron-carbon alloy yi-2.1%, i-graphite recarburizers kunye ne-non-graphite recarburizers yenza ngokulinganayo ngenxa yokumanzisa ngokomzimba;kodwa xa umxholo wekhabhoni wentsimbi enyibilikisiweyo ungaphezulu kwe-2.1%., I-graphite kwi-graphite recarburizer inokuchithwa ngokuthe ngqo kwintsimbi etyhidiweyo, kwaye le nto ingabizwa ngokuba yi-dissolution ngqo.Isenzeko sokunyibilika ngokuthe ngqo se-non-graphite recarburizer akukho nzima ukubakho, kodwa ikharbhon ngokuthe ngcembe iyasasazeka kwaye inyibilika kwintsimbi etyhidiweyo njengoko ixesha lihamba.Ke ngoko, izinga le-carbonation ye-graphite recarburizer liphezulu kakhulu kunelo le-non-graphite recarburizer.

Imibuzo ekufuneka uyiqwalasele xa ukhetha i-carburant:

1. Zama ukusebenzisa i-high-temperature graphitization-treated recarburizers (iqondo lokushisa eliphezulu lonyango, ngcono i-graphitization effect), njengama-electrodes e-graphite okanye i-coke yeoli ye-graphitized.Ngenxa yokuba i-recarburizer efanelekileyo inezinga eliphezulu lokufunxa kunye nesantya sokuchithwa ngokukhawuleza, kunenzuzo ukunciphisa ukusetyenziswa kwamandla, kwaye inokunyusa ngokufanelekileyo i-nucleation core yensimbi etyhidiweyo kunye nokuphucula umgangatho we-metallurgical;

2. Khetha ii-carburizers ezinobumdaka obuphantsi njengesulfure kunye nenitrogen.Umxholo we-nitrogen we-recarburizer enomxholo ophezulu wesulfure nawo uphezulu.Xa umxholo we-nitrogen wentsimbi engwevu yentsimbi enyibilikisiweyo uphezulu kunogxininiso olulinganayo, kulula ukuvelisa imingxunya yenitrogen, kunye nentsimbi enyibilikisiweyo ye-iron ithanda ukucutheka kwiziphene kwiindawo ezinodonga olungqingqwa, kunye nomxholo wokungcola. phezulu.Ukwandisa ukuthambekela kokuphosa ukubandakanywa kwe-slag;

3. Ngokweesayizi ezahlukeneyo zesithando somlilo, ukukhetha ubungakanani obufanelekileyo besuntswana le-recarburizer kunokuphucula ngokufanelekileyo isantya sokufunxa kunye nesantya se-carburant ngentsimbi etyhidiweyo.
