Abstract

PURPOSE:To perform rolling at uniform temp. and to obtain a homogeneous product by heating quickly both edge parts of a hot-rolled material during finish rolling process. CONSTITUTION:The slack of a strip 3 between rolling mills 1 and 2 is controlled to prescribed tension by lifting a looper 5. Between a rolling material press roll 16 and succeeding stand work rolls 2, the material 3 passes always a constant position. Inductors 17, 17' of a high frequency induction heater for heating the edge parts of a rolling material 3 are disposed right after the roll 16 to heat the edge parts. By the use of the roll 16, the passage position of the material 3 is maintained constant between the stands and it is possible to make an air gap sufficiently small within a fairly long range at the high frequency induction heating.
