Interstand cooling
The Inter Stand Cooling (ISC) at strip hot strip mills partakes fundamentally in reaching and maintaining the required finishing rolling temperatures. Thus it enables to reach better mechanical properties of a strip, particularly with microalloyed steels. Very important is the possibility to increase the mill production so that it enables to roll at higher speed or speed up.
Effects of ISC cooling on hot strip mill 2000 m:
- thin strips (< 4 mm): deviation ± 7 °C
- thick strips (> 10 mm): deviation ± 12 °C
- increase of rooling speed: cca 30 %
