在炼钢用的石墨电极或制铝、制镁用的阳极糊（融熔电极）时，为使石油焦（生焦）适应要求，必须对生焦进行煅烧。煅烧温度一般在1300℃左右，目的是将石油焦挥发分尽量除掉。这样可减少石油焦再制品的氢含量，使石油焦的石墨化程度提高，从而提高石墨电极的高温强度和耐热性能，并改善了石墨电极的电导率。石油焦主要用于生产石墨电极、炭糊制品、金刚沙、冶金工业及电石等，其中应用最广泛的是石墨电极。
生焦不经锻烧可直接用于碳化钙作电石主料，生产碳化硅和碳化硼作研磨材料。也可直接作为冶金工业鼓风炉用焦炭或高炉墙衬炭砖，也可作铸造工艺用致密焦等。
Calcined Petroleum Coke comes from delayed coke which extracted from oil refinery. and contains a little bit higher level of sulfur and nitrogen than pitch coke, the price advantage still makes it widely used during steel-making and founding as a kind of carbon additive/carburant.
The main use of CPC is in the production of anodes for the Aluminum Smelting process. 70 - 80% of CPC is for the Aluminum Industry. The reason for use in the Aluminum Industry is for conductivity. Another use for CPC is TiO2 production which accounts for about 15% of the CPC consumption. The reason for use in TiO2 is for its oxidizing effect. metallurgical Industry is the remaining major area where CPC is used. The reason for use in metallurgical Industry is the high Fixed Carbon level (low ash level) and moderate sulfur levels.
