Pre-baking method of aluminum electrolysis anode
The invention relates to the technical field of aluminum electrolysis, in particular to a prebaking method of an aluminum electrolysis anode, which comprises the following steps: placing a green anode in a customized refractory material masonry, isolating air under the protection of a filler, and roasting the prebaked anode by adopting a horizontal continuous roasting furnace, the raw anodes run at a preset speed through a conveying device to prepare prebaked anodes; wherein the horizontal continuous roasting furnace kiln comprises a heating section and a cooling section, and a heat source for roasting treatment of the prebaked anode is provided by volatile components separated out by the green anode, natural gas and other additional fuels. According to the technical scheme, continuous prebaked anode roasting treatment can be conducted, the temperature in the roasting furnace is accurately controlled, volatile components separated out of products are fully utilized, heat losses such as heat storage and release of a traditional roasting furnace are reduced, the energy consumption of prebaked anode roasting is effectively reduced, the production cost is reduced, and the homogeneity of prebaked anodes is improved.
本申请涉及铝电解技术领域，具体而言，涉及一种铝电解阳极的预焙方法，所述方法包括：将生阳极置于定制的耐火材料砌体中，在填充料的保护下隔绝空气并采用水平连续焙烧炉窑进行预焙阳极焙烧处理，所述生阳极通过输送装置按照预设速度运行，制成预焙阳极；其中，所述水平连续焙烧炉窑包括升温段和冷却段，所述预焙阳极焙烧处理的热源由所述生阳极析出的挥发分和天然气等外加燃料提供。本申请提供的技术方案能够进行连续的预焙阳极焙烧处理，精准控制焙烧炉内温度，充分利用制品析出的挥发分，降低传统焙烧炉蓄放热等热量损失，有效降低预焙阳极焙烧能耗、降低生产成本，提高预焙阳极均质性。
