摘要

在阴极铜生产过程中使用现代自动化控制系统,可以远程访问资源,监控和调节电解过程的参数,从而在降低能源成本的同时提高生产效率。电解精炼铜过程中的重要参数包括电解液的温度和成分、电解液的循环速度、淤积程度、电极间短路的频率以及电流密度,这些参数直接影响电解槽底部阴极沉积物体积的质量。电解槽中出现短路的原因是树枝状突起的生长,因此需要控制电解液的电压、成分和温度,并定期分析其成分和电解槽底部沉积污泥的累积量。电解过程的强化主要是由于电流密度的增加、电极间距离的减小、电极质量的改善、电解液循环系统的改进,以及过程本身及其辅助操作的进一步机械化和自动化,从而提高了生产率。这项工作的目的是通过引入污泥液位控制传感器来扩展 APCS 的功能,利用新软件减少电解槽下部电极上树枝状沉积物短路时不可挽回的损失。我们考虑了一种控制污泥沉积物液位以防止短路的方法,并利用电解液和污泥沉积物的浮子型液位传感器开发了一个控制程序。这项措施实施后,能耗将减少 15-20%,有助于在铜冶炼厂(越南社会主义共和国老街市)的电解铜生产车间实施。

Improving the Control and Management System for the Parameters of Electrolytic Copper Refining

Improving the Control and Management System for the Parameters of Electrolytic Copper Refining

The use of modern automated control systems in the production of cathode copper provides the possibility of remote access to resources for monitoring and regulating the parameters of the electrolytic process, which determines the efficiency of production while reducing energy costs. Important parameters in the electrolytic refining of copper are the temperature and composition of the electrolyte, the circulation rate of the electrolyte, the level of sludge, the frequency of short circuits between the electrodes, and the current density, which directly affect the quality of the volume of the cathode deposit at the bottom of the electrolytic cell. The presence of short circuits in the bath is due to the growth of dendrites, which entails the need to control the voltage, composition, and temperature of the electrolyte, and to periodically analyze their composition and the accumulation of the volume of sludge sediment at the bottom of the electrolyzer. The intensification of the electrolysis process occurs mainly due to an increase in the current density, a decrease in the interelectrode distance, an improvement in the quality of the electrodes, an improvement in the electrolyte circulation system, with further mechanization and automation of the process itself and its auxiliary operations, leading to an increase in productivity. The purpose of this work is to expand the functions of the APCS by introducing sludge level control sensors to reduce irrecoverable losses in the presence of short circuits of dendritic sediment on the electrodes in the lower bottom of the electrolyzer using new software. A method for controlling the level of sludge sediment to prevent short circuits is considered, and a control program is developed using float-type level sensors for electrolyte and sludge sediment. This measure, when implemented, will reduce energy consumption by 15–20%, which can be useful for implementation in the electrolytic copper production shops at the Copper Smelting Plant (Lao Cai City, Socialist Republic of Vietnam).

期刊介绍: Russian Metallurgy (Metally)  publishes results of original experimental and theoretical research in the form of reviews and regular articles devoted to topical problems of metallurgy, physical metallurgy, and treatment of ferrous, nonferrous, rare, and other metals and alloys, intermetallic compounds, and metallic composite materials. The journal focuses on physicochemical properties of metallurgical materials (ores, slags, matters, and melts of metals and alloys); physicochemical processes (thermodynamics and kinetics of pyrometallurgical, hydrometallurgical, electrochemical, and other processes); theoretical metallurgy; metal forming; thermoplastic and thermochemical treatment; computation and experimental determination of phase diagrams and thermokinetic diagrams; mechanisms and kinetics of phase transitions in metallic materials; relations between the chemical composition, phase and structural states of materials and their physicochemical and service properties; interaction between metallic materials and external media; and effects of radiation on these materials.
