Abstract

Interstand Cooling (ISC) can help to increase the productivity of the mill and improve the final mechanical properties of the strip. Constant Exit Rolling Temperature (ERT) can be ensured on the whole strip length eliminating temperature oscillations of the transfer bar caused by skid marks and other reasons. The paper presents experimental possibilities in investigation and design of ISC headers. Experimental stand is introduced and a complex approach – experiment and mathematical modeling – is shortly described. Further essential models of control system are introduced and basic functionality is explained. In conclusion practical experiences are discussed.
