A mathematical model is proposed for the mill arrangement equivalent to semi continuous type in a hot strip mill. The rolling schedule is arranged so that a slab is rolled from 230 mm into 60 mm in bar thickness by reversibly three passes roughing and 60 mm into 1.2 mm, 2.0 mm and 2.5 mm in final thickness by seven passes finishing. The possibility of rolling in this case is analytically examined in due consideration of slab weight, temperature change, rolling power, rolling capacity and rolling speed. As a result, the rolling of the comparably heavy slab with 30t/m in unit weight is enabled, and the temperature condition is sufficiently fulfilled. The length of the rolling mill line can be geometrically shortened very much in comparison with the case of other type hot strip mill.
