Anode carbon block and preparation method thereof
The invention relates to a preparation method of an anode carbon block, which comprises the following steps: 1) taking petroleum coke, carrying out high-temperature treatment at 1250-1350 DEG C, crushing and screening, taking petroleum coke particles with the particle size of 25-100mm as aggregate, returning petroleum coke blocks with the particle size of more than 100mm, crushing again, and grinding petroleum coke particles with the particle size of less than 25mm to obtain powder; 2) taking coal pitch, and preserving heat for later use; (3) mixing and kneading the aggregate and the powder obtained in the step (1) and the coal pitch obtained in the step (2) to obtain a paste material, and carrying out vibration molding on the paste material to obtain a green body, in the paste material, the powder material accounts for 35-40wt%, the pitch accounts for 14.5-15.5%, and the balance is the aggregate; 4) cooling the green body to room temperature; and 5) calcining the green body in a sealed space to obtain the anode carbon block. The anode carbon block with relatively high mechanical strength, excellent oxidation resistance and good electrochemical performance is prepared by configuring a raw material formula of the green body and technological parameters of a production process.
一种阳极炭块的制备方法，包括步骤：1)取石油焦，经1250‑1350℃高温处理后，经破碎筛分，取粒度为25‑100mm的石油焦粒作为骨料，粒度＞100mm的石油焦块返回再次破碎，粒度小于25mm的石油焦粒经磨粉，得到粉料；2)取煤沥青，保温备用；3)将步骤1)得到的骨料和粉料，以及步骤2)的煤沥青混捏得到糊料，糊料振动成型，得到生坯，糊料中粉料的占比为35‑40wt％、沥青的占比为14.5‑15.5％，余量为骨料；4)生坯降温至室温；5)生坯在密封空间中煅烧，得到阳极炭块。本发明通过配置生坯原料配方、生产过程工艺参数，制备得到具有较高机械强度、优异抗氧化能力、电化学性能良好的阳极炭块。
