Main Components

The article deals with the description of an improved automatic control system for steel-making furnaces (electric arc furnaces and ladle furnaces) electrode positioning and the results of its production testing. The control performance of electrode positioning of the developed automatic control system was studied using a mathematical model, which included the main components of the system: the hydraulic drive of electrode positioning with a servo valve, electric circuit of the furnace described by Cassie nonlinear differential equation, impedance nonlinear controller. It was proved that a more accurate positioning makes it possible to significantly reduce electric power consumption per tap-to-tap cycle.

The paper discusses a new approach to improving the accuracy of reproducing the task signal by a precision circular transfer table based on the implementation in the form of a mechatronic module. This design eliminates the disadvantages of the traditional design, such as backlash, failure when fixing the face-plate. The mechatronic module is a gearless connection between the face-plate and the electric motor. The new design required a new approach to the operation of the automatic tracking and stage positioning control system. In the process of stage positioning, thermal deformations occur, and therefore, a feature is the inclusion of an additional automatic control system for the cooling of an executive synchronous electric motor with permanent magnets in the rotor. The paper deals with the issue of the interrelationship between the positioning and tracking systems with the thermal deformation compensation system. Simulation of the operation of two systems has been carried out.
