る。2. Description of the Related Art In general, a steel strip hot rolling line is provided with equipment in the order of a heating furnace, a rough rolling mill, a finishing rolling mill, and a winding machine, and a slab heated at a predetermined time pitch from the heating furnace is formed into a line. Supplied and efficient rolling work is performed. By the way, for example, when a trouble occurs after the finish rolling mill and the line is temporarily stopped, the next material is often taken out of the heating furnace and rolling has already started in the rough rolling mill. Since the length of the rolled material is longer, it is no longer possible to return to the heating furnace, but if it cannot be supplied to the finishing mill, the semi-finished product ( Seat bar, also called cobble)
Need to be taken out of the line. Conventionally, in general, a simple method has been adopted in which gas is manually cut off and then carried out of the line by an overhead crane with a C hook. , A pusher, a lifter, etc., to take out the semi-finished product. As an example, a semi-finished product (cobble) carry-out processing apparatus described in Japanese Utility Model Laid-Open No. 6-086901 will be described with reference to FIG.
