[] Kucetyiswa ukuba ukhethe i-graphitized petroleum coke njenge-carburizer ye-ductile iron ngenxa yezi zizathu zilandelayo:
- Ulwakhiwo lweekhemikhali olugqwesileyo:
- I-graphitized petroleum coke: Ihlala iqulethe ngaphezu kwe-99.5% yekhabhoni kunye ne-sulfur engaphantsi kwe-0.05%. Iimpawu zekhabhoni ephezulu kunye ne-sulfur esezantsi zinceda ukonyusa umxholo wekhabhoni we-ductile iron ngelixa zinciphisa imiphumo emibi yesalfure kwi-nodularization kunye ne-graphitization, ngaloo ndlela zithintela iziphene kwi-castings.
- I-carburizer ye-anthracite ekhalisiweyo: Ngokubanzi inomxholo wekhabhoni oyi-90-93% kunye nomxholo wesalfure oyi-0.3-0.5%. Umxholo wekhabhoni ophantsi kunye nomxholo wesalfure ophezulu kunokunyusa umxholo wesalfure kwi-castings, okuchaphazela isiphumo se-nodularization kunye neempawu ze-cast.
- Ukusebenza kakuhle kokufunxa:
- I-graphitized petroleum coke: Ixhomekeke kunyango lwe-graphitization lobushushu obuphezulu, ii-athomu zekhabhoni zicwangciswe ngendlela ehlelekileyo, zenze isakhiwo se-graphite esirhabaxa. Oku kwenza kube lula ukunyibilika nokufunxwa ngokukhawuleza kwisinyithi esinyibilikisiweyo, nto leyo ekhokelela ekusebenzeni kakuhle kwe-carburization kwaye inyuse ngokufanelekileyo umxholo wekhabhoni kwisinyithi esinyibilikisiweyo.
- I-calcined anthracite carburizer: Xa inomxholo wekhabhoni ophantsi, iyanyibilika kancinci kwaye inokusebenza okuncinci kokufunxa, nto leyo enokwandisa ixesha lokunyibilika kwaye inyuse ukusetyenziswa kwamandla.
- Impembelelo kwi-nodularization kunye ne-graphitization:
- I-graphitized petroleum coke: Umxholo ophantsi wesalfure unciphisa ukuphazamiseka kwe-arhente ye-nodularizing, nto leyo enceda ekufezekiseni iziphumo ezilungileyo ze-nodularization kunye ne-graphite morphology, ngaloo ndlela iphucula iipropati ze-mechanical ze-ductile iron.
- I-calcined anthracite carburizer: Umxholo ophezulu wesalfure unokuphazamisana nenkqubo ye-nodularization, nto leyo echaphazela i-nucleation kunye nokukhula kwe-graphite, nto leyo ekhokelela kwiipropati zokuphosa eziwohlokileyo.
- Umgangatho wokuphosa:
- I-graphitized petroleum coke: Ukuyisebenzisa kuphumela kumgangatho ophezulu we-metallurgical we-castings, kuphucula ngokufanelekileyo amandla kunye nokuqina kwe-ductile iron kunye nokunciphisa iziphene ezifana ne-porosity kunye ne-shrinkage, ngaloo ndlela kuphucula izinga lokufaneleka kwemveliso.
- I-carburizer ye-anthracite ekhalisiweyo: Ngenxa yokuba inomxholo ophezulu wesalfure, inokubangela ukubola kwi-castings kwaye inciphise iimpawu zoomatshini, nto leyo echaphazela umgangatho we-cast.
- Iindleko zokusetyenziswa:
- I-graphitized petroleum coke: Nangona ixabiso layo linokuba phezulu kancinci kunele-calcined anthracite carburizer, ukusebenza kwayo okuphezulu kwe-carburizer kunciphisa ubungakanani be-carburizer efunekayo, kunciphisa iindleko zokunyibilika. Ukongeza, iphucula umgangatho wemveliso kwaye inciphisa izinga le-scrap, nto leyo ebangela ukuba iindleko zokusetyenziswa ziphantsi.
- I-carburizer ye-anthracite ekhalisiweyo: Nangona ixabiso layo liphantsi, ukusebenza kwayo okuncinci kokufunxa kunokubangela ukusetyenziswa okwandisiweyo, kwaye inokuchaphazela umgangatho wokwenza i-casting, nto leyo ekhokelela kwiindleko eziphezulu zokucubungula emva koko.
