摘要
PURPOSE: To produce various kinds of coil easily with continuous operation or discontinuous operation by arranging a cooling device, pickling device, trimmer and coiling machine at the downstream of heat treatment furnace. CONSTITUTION: A steel strip 1 continuously cast with the twin roll 2 of continuous casting machine is sent into a hot rolling mill 4 with a pinch roll 3 and introduced into a heat treatment furnace 5. Pinch rolls 6, 7 at the incoming/ outgoing sides of heat treatment furnace 5 executes tension control in the heat treatment furnace. The strip 1 having 900-1250 deg.C is cooled down to about 100 deg.C by a cooling device 8 at its downstream. The strip 1 removed its scale by a mechanical descaling device is introduced into a pickling liquid 13 in a pickling tank 12. Subsequently, the strip 1 is passed through a trimmer 15, edge heater 16 and coiled by coiling machines 17a, 17b. By this method, reduction of cost in pickling process and trimming process is achieved as well as shortening delivery time.
