| 摘 要： | 将煅前石油焦压密和煅烧，通过体积密度、真密度、显气孔率、粉来电阻率、颗粒抗压碎强度的测试，研究压密煅烧石油焦特性。采用压密煅烧石油焦制成预焙阳极。通过体积密度、真密度、显气孔率、电阻率、耐压强度、透气度的测试。结果表明，压密石油焦能显著地改善预焙阳极的理化性能，使预焙阳极制造过程中沥青加入量控制在13％，预焙阳极的体积密度达到I．65g／cm^3．强度达到50MPa。

| Abstract: | A test is done on pre- baked anode made from calcined coke in aspects of apparent density, real density, porosity, resistivity of powder, compressive strength, which shows compressed petroleum coke improves its chemical and physical performances. When the amount of pitch is controlled at 13% in making pre - baked anode, the apparent density of pre - baked anode may be 1.65 c/m^3 and the strength be 50 MPa. |

| Keywords: | Pre - baked anode compressed petroleum coke apparent density compressive strength resistivity porosity |
