Production method of porous anode carbon block for electrolytic aluminum
The invention discloses a production method of a porous anode carbon block for electrolytic aluminum. The method comprises the following steps: placing petroleum coke in a rotary kiln or a pot furnace for calcining to obtain calcined coke, and crushing the calcined coke; putting 71% of the crushed calcined coke, 26% of the anode scrap and 3% of the raw scraps into a preheating screw conveyor for heating and pre-mixing, putting the aggregate and the asphalt binder at 180 DEG C into a continuous kneading machine or a kneading pot for kneading to obtain a paste material; putting the mixed and kneaded paste into a powerful cooling machine for cooling; placing the prefabricated aluminum rod support in a vibration forming machine; putting the cooled paste into a vibration molding machine with an aluminum rod support for vibration molding to obtain a green anode carbon block; and making the green anode carbon block precisely drilled in the drilling station and making the end of the aluminum rod support cleaned and exposed, placing the cleaned green anode carbon block with the end of the aluminum rod support cleaned and exposed in a roasting workshop, and performing cooling to obtain the porous anode carbon block for porous electrolytic aluminum.
本发明公开了一种电解铝用多孔阳极炭块生产方法，包括以下步骤：将石油焦放入回转窑或罐式炉中煅烧，煅烧后得到煅后焦并破碎；将破碎后的煅后焦、残极和生碎按照71%煅后焦、26%残极和3%生碎的比例放入预热螺旋机内加热预混合；将骨料和180℃沥青粘结剂一起放入连续混捏机或混捏锅内进行混捏，得到糊料；将混捏好的糊料放入强力冷却机冷却；把预制好的铝杆支架放入振动成型机内；将冷却好的糊料放入放置有铝杆支架的振动成型机内振动成型，得到生阳极炭块；将生阳极炭块在钻孔工位进行精准钻孔，使铝杆支架的端头清理露出，将清理过的露出铝杆支架端头的生阳极炭块放入焙烧车间，冷却后得到多孔电解铝用多孔阳极炭块。
