Abstract

Gas purification in ferroalloy furnaces is vital for the efficiency and quality of the entire production process. To enhance the efficiency of the gas purification system, an upgrade to the bag filter regeneration control system has been proposed. Using the SimInTech dynamic modeling environment, the performance of the control system was evaluated before and after modernization. Key quality indicators and misalignment errors were calculated to assess the proposed engineering solution. The speed increased by 3.8 times, reducing response time to 2.9 s, the stability increased by 3 times, achieving a stability degree of 1.05, the reliability of the control system increased by 4.2%, reaching a reliability rate of 96.3%, and the misalignment error decreased by 30 s, resulting in a misalignment error of 25 s. Operational data from the Aktobe Ferroalloy Plant were used to assess the impact of the modernization on productivity, energy efficiency, and the overall quality of the gas purification system. The average efficiency coefficient of the regeneration system was determined to be 34.75%.

铁合金炉气体净化控制系统的现代化

铁合金炉中的气体净化对整个生产过程的效率和质量至关重要。为提高气体净化系统的效率，建议对布袋除尘器再生控制系统进行升级。利用 SimInTech 动态建模环境，对控制系统现代化前后的性能进行了评估。计算了关键质量指标和偏差误差，以评估所提出的工程解决方案。速度提高了 3.8 倍，响应时间缩短至 2.9 秒；稳定性提高了 3 倍，稳定度达到 1.05；控制系统的可靠性提高了 4.2%，可靠率达到 96.3%；对中误差减少了 30 秒，对中误差为 25 秒。阿克托别铁合金厂的运行数据用于评估现代化对生产率、能效和气体净化系统整体质量的影响。再生系统的平均效率系数被确定为 34.75%。
