Study of the Effect of the Rolling Mill Inter-Stand Tension on the Strip Gauge Deviation

Abstract:

The paper studies issues of the cross impact of tension and strip gauge at the rolling in the continuous roughing sub-train of the wide strip hot-rolling mill. Functional dependencies and chart of the mathematical model defining interrelation between the specific tension and strip gauge increment are provided. Based on the example of the 2,000 mm hot rolling mill of OJSC Magnitogorsk Iron and Steel Works (OAO MMK), it has been proved that rolling is carried out with tension values which exceed several times allowable values. The paper also considers new technical solutions enhancing the speed mode control algorithms and systems of the electric drives of the wide strip hot-rolling mill continuous subgroup.
