Pre-baked anode produced by taking pellet coke as main material and production process of pre-baked anode
The invention provides a prebaked anode produced by taking pellet coke as a main material and a production process of the prebaked anode, and the process comprises the following steps: S1, taking pellet coke as a raw material to prepare fine powder calcined coke which is a secondary material; s2, preparing auxiliary materials; s3, proportionally preparing the secondary material obtained in the step S1 and auxiliary materials into a dry material; and S4, producing the prebaked anode by using the dry material obtained in the step S3, and finally obtaining the prebaked anode produced by taking the shot coke as the main material. The petroleum coke containing the pellet coke is reasonably utilized, the selection range of aluminum anode resources is widened, and the sustainability of anode production can be kept; active points on the surface of the secondary material are increased when the coke breeze forming block is crushed, formation of chemical bonds during compression forming of an anode sample is facilitated, secondary material particles are stacked more tightly, the internal structure of the anode is compact, the strength of the anode sample is further improved, and the performance of the anode in all aspects is effectively improved.
本发明提供一种以弹丸焦为主料生产的预焙阳极及其生产工艺，该工艺包括如下步骤：S1、以弹丸焦为原料制备一种细粉煅后焦，所述细粉煅后焦即为二次料；S2、准备辅料；S3、将步骤S1得到的二次料与辅料按比例配置成干料；S4、利用步骤S3得到的干料生产预焙阳极，最后得到一种以弹丸焦为主料生产的预焙阳极。合理利用了含有弹丸焦的石油焦，拓宽了铝用阳极资源选择范围，有利于保持阳极生产的可持续性；粉焦成型块破碎时增加了二次料表面的活性点，有利于阳极样品压制成型时化学键的形成，同时二次料颗粒堆积更紧密，使阳极内部结构致密，进而提高阳极样品的强度，有效提高阳极的各方面性能。
