PURPOSE:To prevent a large damage caused by the troubles generating at the side of a continuous casting machine by disposing a cooling device and a cutting device just at the back of the casting machine in a manufacturing line where a continuous casting machine having a solidifying part is directly connected to a rolling mill. CONSTITUTION:A cast billet 7 cast by pouring a molten material into a continuous casting machine, e.g. a main body 1 of rotary caster, is drawn by a drawing device 2 while keeping its inside in unsolidified state. Successively, the billet 7 is perfectly subjected to a solidifying and thermal adjustment by the cooling and soaking devices 3, 4 of a horizontal solidifying part, and is formed into a prescribed cross-sectional shape by a line 5 of rolling mills before cutting it into a product 8 by a cutter 6. In this installation, a cooling device 9 and a cutting device 10 are disposed just at the back of the main body 1. When a trouble generates at the main body 1 side, a cut part 7' of billet 7 is cooled and solidified by the device 9 just after stopping once the body 1 and the line 5. The billet 7 is thereafter cut by the device 10, and a remaining billet is rolled just after completing the cutting by operating only the mill side. In this way, the lowering of yield due to a scrap treatment of remaining billet is prevented. |
