Icoke yepetroleum yepetroleum ecocekileyo ecocekileyo yenziwe ngepetroleum coke ekumgangatho ophezulu phantsi kobushushu obuyi-2,500-3,500 ℃. Njengomgangatho ophezulu wekhabhoni ococekileyo, uneempawu eziphezulu zekhabhoni eziqingqiweyo, i-sulfure ephantsi, i-ash ephantsi, i-porosity ephantsi njl.Ingasetyenziselwa njenge-carbon raiser (i-Recarburizer) ukuvelisa i-high quality steel, i-cast iron kunye ne-alloy.Inokusetyenziswa kwakhona kwiplastiki kunye ne-rubber njenge-additive.
