PURPOSE:To improve the furnace efficiency and to reduce the equipping cost by arranging tilting table roller at least on the material extraction side of a heating furnace arranging plural steps of hearth roller train and enable heating at the same time, the material to be rolled and the material on the way for rolling. CONSTITUTION:Continuous casting equipment (not shown in the figure) and the rolling mill equipment 2 are directly connected with the heating furnace equipment 1 through the roller table 3. The above heating furnace equipment 1 is constituted by the heating furnace 11 providing the plural steps of hearth roller train 111 and the tilting roller table 12 arranged at the material extractive side. This hearth roller train 111 can be operated in both normal and reverse directions and on the other hand, the tilting roller table 12 is tiltable, centered on the supporting point 121, so as to be able to connect the roller table 3 with each hearth roller line 111. In this way, for example, the metrical to be rolled is heated on the upper step hearth roller train 111 and at the same time, the material on the way for rolling is heated on the lower step hearth roller train 111 by reversely carrying the material on the way for rolling, and the heating furnace 11 is applied three dimensionally.
