Experience of Rolling Patterns with an Inverse Temperature Wedge on the NShSGP 2000 Continuous Wide-Strip Hot-Rolling Mill

详细

This article discusses possible approaches to increase the capacity of a finishing train using strip rolling with an inverse temperature wedge. One calendar year of operation of a continuous wide-strip hot-rolling mill (NShSGP) is considered. Analysis of plant data demonstrated that the rolling time is by 7–10% lower in the case of rolling with an inverse temperature wedge, which allows increasing overall mill capacity. The obtained results can be applied during rolling of low carbon steels for cold pressing, and their fraction in mill production prevails; thus, it is possible to significantly increase mill capacity without making additional capital investments.
