Additional information

The aim of the complex research is the development and implementation of control methods and improvement of technological processes of cold rolled strips production, ensuring reduction in rejection by flatness and improving the efficiency of the equipment, control systems and technological modes of treatment.

Experimental study of the effect of velocity and strain-force modes on the thermal conditions of rolling and the effectiveness of strips flatness regulation

The main results of performed works:
1. In endless rolling mill 2030 NLMK in 2000-2001 were discovered causes of inefficient channel work of selective rolls cooling and the main ways to improve its effectiveness.
2. Experimentally determined and implemented technological solutions for effective strips flatness regulation by work rolls selective cooling.
3. Implemented a set of new methods and ways of strip flatness regulation due to which the average error of flatness reduced TWICE, and had developed new products.

CONFIRMED overall economic effect amounted to 67.726 million rubles.

Performed a set of works to improve the flatness of the strips, formed the basis of significant practical results presented in scientific papers and thesis.
