SUMMARY:Compensation of process fluctuations with an auto-adaptive electrode control system
DESCRIPTION:"Melting steel has always been a challenging process. There has been a lot of development in automating this process in the past decades. However, most EAF steel is still produced using static melting profiles. Those profiles treat all the heats the same and are ignoring regular fluctuations. Fluctuations come from charged material eg scrap quality, alloying material, DRI/HBI quality as well as stability of electrical supply. Both have influence on the production results. For example, deviation in scrap or DRI/HBI quality or variation in primary voltage from the grid.

The next level of process control is monitoring these variations and their impacts and applying countermeasures for process optimization and minimizing energy consumption. Sophisticated electrode control systems already have a huge amount of information, but typically this has not been used for process improvement. Recent developments combining the information already available are providing intelligent process derived strategies bringing a new level of process optimization. Integrating these improvements into the electrode control system enables the precise control of the electrical and chemical power input according to the current process needs. As a result, the fluctuations of the consumption figures and power on times will be minimized leading to greater production efficiency and reduced costs.

The idea and implementation of such strategies as well as results achieved will be shown in this paper. "
