High-graphite vertical forming production method
The invention belongs to the technical field of electrode forming methods, and particularly discloses a high-graphite vertical forming production method which comprises the following steps: S1, preparing raw materials including turning chips, workshop tail powder and coal pitch; s2, performing pre-crushing and intermediate crushing and grinding; s3, burdening is conducted, specifically, the turned scraps, the workshop tailings and the coal pitch are weighed and proportioned, the turned scraps account for 45%-65% of the total weight, the workshop tailings account for 20%-45% of the total weight, and the coal pitch accounts for 10%-18% of the total weight; s4, dry mixing; s5, wet mixing; s6, airing the materials; s7, weighing is carried out, wherein the aired materials are weighed; s8, molding: adding the weighed paste into molding equipment for molding; and S9, cooling: cooling the raw product after demolding. The problems that the technical index of the high-graphite electrode produced by the existing method for producing the high-graphite electrode by recycling leftover bits and pieces cannot meet the requirement, the internal stress of the product cannot be eliminated, and the surface and internal cracks are serious can be solved.
本发明属于电极成型方法技术领域，具体公开了高石墨质立式成型生产方法，包括以下步骤：S1：准备原料：原料包括车削碎、车间尾粉和煤沥青；S2：预碎及中碎磨粉；S3：配料：将车削碎、车间尾粉和煤沥青进行称重配比，车削碎占总重量的45％‑65％，车间尾料占总重量的20％‑45％，煤沥青占总重量的10％‑18％；S4：干混；S5：湿混；S6：晾料；S7：称重：对晾料后的物料进行称重；S8：成型：将称重后的糊料加入至成型设备中进行成型；S9：冷却：出模后将生制品进行冷却。能够解决目前将边角余料再利用来生产高石墨质电极的方法，生产出来的高石墨质电极技术指标达不到要求，产品内应力无法消除，表面及内部裂纹严重的问题。
