添加石油焦改善冶金焦铸造焦的质量

本文论述了国外添加石油焦提高焦炭质量的研究动向。指出在强粘结性煤中添加一定量的细粒石油焦能减少焦炭的裂纹和孔隙率，降低焦炭的反应性，增加焦炭的机械强度和反应后强度，提高焦炭的块度，可满足铸造焦和冶金焦的质量要求。表明石油焦的添加量和粒度对焦炭性能有较大影响，并对石油焦的作用机理进行了讨论

Improvement of Metallurgical Coke by Addition of Petroleum Coke

The research tendencies at abroad are reviewed on the production of metallurgical coke of high quality by addition of petroleum coke.It is indicated that the addition of petroleum coke results in the decrease of the coke cracle and porosity,the increase of mechnical strength,post strength,and lump size,thus the conformance with the quality standards on cast coke and metallurgical coke.It is shown that the quantity and particle size of petroleum coke was also discussed
