Description

technical field

[0001] The invention relates to a multifunctional intelligent electrode controller, which belongs to the technical field of metallurgical automation control. Background technique

[0002] The electrode controller is used to control the arc current (that is, the current, the same below) in order to realize the melting of scrap steel or the reasonable temperature rise of molten steel. Generally speaking, the electrode controller must complete at least two functions. One is to effectively control the rise and fall of the electrode to make the actual arc current as stable as possible (as close as possible to the set value of the arc current) and the electrode vibration as small as possible. Different equipment and certain technical means are used to formulate the optimal arc current setting value corresponding to different transformer voltage levels during the smelting process (the so-called power set point optimization). From the point of view of energy saving ...
