精炼铁合金工艺流程分为引弧、熔化和精炼三个顺序期,每期的负荷要求不同,一般通过手动控制电极升降,即通过改变电炉熔池电阻来改变各期的负荷值。但手动控制存在电流调节不及时,负荷控制偏低和三班操作不统一的问题。上海铁合金厂与上海自动化研究所通过二年多来共同努力,解决了微处理机用于精炼铁合金电炉负荷控制的技术难题。应用微
The process of refining ferroalloy is divided into arc sequence, melting sequence and refining sequence. The load requirements of each period are different. Generally, the electrode is controlled by manual control, that is, the load value of each period is changed by changing the resistance of the arc furnace bath. However, the manual control of current regulation is not timely, low load control and the problem of three shifts are not uniform. Shanghai Ferroalloy Plant and Shanghai Institute of Automation through more than two years to work together to solve the microprocessor for refining iron alloy furnace load control technical problems.
