Purpose: The aim of this paper is design of modernization of control valves of finishing mill to control the counter-bending forces on the last stands by replacement of proportional valves with regulating ones. Design/methodology/approach: New board (construction, location and arrangement of valves) was designed, model of which was constructed by SolidWorks software. Findings: The solution was oriented to optimization by replacement of proportional valves for regulating ones to control the counter-bending forces on the rolling mills. The selected types of proportional and regulating valves were compared. The main advantage of the application of regulating valves is integrated electronics with position controller for pilot valve control and position feedback disposal. Based on the parameters of the regulating valve the new respite and relief valves were designed. Research limitations/implications: Design of substitution of upper and lower blocks of control valves and modelling the motherboards using SolidWorks software was conditional by dimensions of currently used hydraulic components and dimensions of the proposed valves. Designed blocks ensure the functioning of the control system of counter bending of working rolls. In the future the perspective to control the counterbending forces can be carried out by innovation of the rolling mill by pump control using asynchronous converters and/or by changing the structure of the arrangement of rolling mill and by design of CVC control of the rolling mill. Practical implications: New board (construction, location and arrangement of valves) was designed, model of which was constructed by SolidWorks software. Designed board ensures the functioning of the control system for counter-bending of working rolls. Originality/value: The result of the proposed solutions is increasing the quality of the hot rolled strip i.e. reduction of the strip waviness and keeping the cross section of the strip.
