400kA预焙槽黑料影响分析及管控优化实践OA
Analysis of the Impact of Black Material on 400kA Prebaked Electrolytic Cells and Practice of Its Control Optimization
本文以400kA预焙电解槽为研究对象,针对阳极焙烧烟气净化黑料对电解生产产生的负面影响,系统开展了黑料特性分析、影响量化评估及综合治理技术研究.通过2024年11-12月现场取样与生产运行数据综合分析,明确黑料粒度超标、杂质含量偏高是导致电解槽电压波动、电流效率下降、原铝质量不稳定的关键因素,可使吨铝电耗增加约100度.在此基础上,研究构建了"源头管控-工艺适配-现场优化-应急保障"四位一体综合治理体系,并完成现场实践验证.研究成果可为同类电解铝企业解决原料异常问题提供参考,同时为车间实现精细化、智能化生产提供支撑.
In this paper,a 400 kA prebaked electrolytic cell is taken as the research object.Aiming at the negative impact of black dust from anode baking flue gas purification on electrolytic production,studies on characteristic analysis,impact quantification and comprehensive treatment are carried out.Based on sampling and production data analysis from November to December 2024,it is determined that excessive particle size and high impurity content of black dust are the key factors causing cell voltage fluctuation,reduced current efficiency and unstable primary aluminum quality,with an increase of approximately 100 kWh in power consumption per ton of aluminum.A four-in-one comprehensive treatment system of"source control-process adaptation-on-site optimization-emergency support"is constructed and verified on site.This research provides a reference for raw material abnormality treatment in similar enterprises and supports the refined and intelligent production of the workshop.
