Abstract

The question of the development of a method for reducing the dynamic loads of the electric drive of the mill of the endless cold rolling was reviewed. The research was conducted on the example of the stand №4 cold rolling mill "2030" PHPP "NLMK". The question of the mathematical description of the electromechanical rolling mill system as a system with the elasticity of the first type was discussed. The analysis of the influence of the tensioning in the moment of the cold rolling mill electric drive load was carried out. The simulation of the rolling mill electric drive system was reviewed. The conclusions about the effect of the elasticity presence to the mode of elastic torque and the dynamic loading of electromechanical system mill gears were made. The methods for reducing the dynamic loads were reviewed. The optimum way for reducing the elastic torque to the gear of the electromechanical system mill was developed. Mathematical simulation was carried out using the Matlab 2011 software and application SImulink. Oscillogram charts were created using software FADEX.
