Icoke yepetroleum enegraphiti
1. Inkcazelo ngeMveliso:
I-coke yepetroleum yegrafi ibalwa njenge-coke yepetroleum njengezinto ezikrwada, emva kobushushu obuphezulu begraphitization, ukusabela ngokwasemzimbeni kunye nemichiza kunye nothuthu lokususwa kwesulfure kunye nobunye ukungcola emva kokuba imveliso ngamanye amaxesha ibizwa ngokuba yigraphite yokwenziwa, esetyenziswa kwi-carburizing agent, edla ngokubizwa ngokuba yi-ultra-low sulphur/low. i-nitrogen carburizing agent.I-Graphitized petroleum coke yimveliso yepetroleum emnyama okanye emnyama engwevu eqinileyo, isinyithi esicwebezelayo, esinerhashalala, yenziwe ngegraphite encinci ekhazimliswe kwigranular, ikholamu okanye inaliti yomzimba wekhabhoni.I-petroleum coke yi-hydrocarbon, equkethe ngaphezu kwe-99% yekhabhoni, kodwa iqulethe i-nitrogen, i-chlorine, i-sulfure kunye neekhompawundi zetsimbi enzima.
2. Iipropati kunye nokusetyenziswa:
I-Graphitized petroleum coke isetyenziswa kakhulu kushishino.Isetyenziswa kwi-metallurgy, ukuphosa kunye nokuphosa ngokuchanekileyo njenge-agent carburizing.Isetyenziselwa ukwenza ubushushu obuphezulu begraphite crucible ukunyibilika, i-lubricant kwishishini lomatshini, ukwenza igraphite electrode kunye nepencil lead.
