焦(jiao)炭(tan)(tan)(tan)用(yong)(yong)(yong)途(tu)焦(jiao)炭(tan)(tan)(tan)主要(yao)用(yong)(yong)(yong)于(yu)(yu)高(gao)爐煉(lian)(lian)鐵(tie)(tie)(tie)和用(yong)(yong)(yong)于(yu)(yu)銅、鉛(qian)、鋅、鈦、銻、汞等有色(se)金(jin)屬的(de)鼓(gu)風(feng)爐冶(ye)煉(lian)(lian)，起還(huan)原劑(ji)、發熱劑(ji)和料柱骨架(jia)作(zuo)用(yong)(yong)(yong)。煉(lian)(lian)鐵(tie)(tie)(tie)高(gao)爐采用(yong)(yong)(yong)焦(jiao)炭(tan)(tan)(tan)代替木炭(tan)(tan)(tan)，為現(xian)代高(gao)爐的(de)大型化奠(dian)定了基礎，是(shi)冶(ye)金(jin)史上的(de)一個重大里程(cheng)碑。為使高(gao)爐操作(zuo)達到較(jiao)好的(de)技(ji)術經濟指標，冶(ye)煉(lian)(lian)用(yong)(yong)(yong)焦(jiao)炭(tan)(tan)(tan)（冶(ye)金(jin)焦(jiao)）必須具有適當的(de)化學性質(zhi)(zhi)和物理性質(zhi)(zhi)，包括(kuo)冶(ye)煉(lian)(lian)過(guo)程(cheng)中的(de)熱態性質(zhi)(zhi)。焦(jiao)炭(tan)(tan)(tan)除大量用(yong)(yong)(yong)于(yu)(yu)煉(lian)(lian)鐵(tie)(tie)(tie)和有色(se)金(jin)屬冶(ye)煉(lian)(lian)（冶(ye)金(jin)焦(jiao)）外，還(huan)用(yong)(yong)(yong)于(yu)(yu)鑄造(zao)、化工、電石和鐵(tie)(tie)(tie)合金(jin)，其質(zhi)(zhi)量要(yao)求有所不同。如鑄造(zao)用(yong)(yong)(yong)焦(jiao)，一般要(yao)求粒度大、氣(qi)孔(kong)率低、固(gu)定碳高(gao)和硫分低；化工氣(qi)化用(yong)(yong)(yong)焦(jiao)，對強(qiang)度要(yao)求不嚴，但要(yao)求反應性好，灰熔點較(jiao)高(gao)；電石生產用(yong)(yong)(yong)焦(jiao)要(yao)求盡量提高(gao)固(gu)定碳含量。
