A method for continuous production of hot-rolled strips is used at metal works and involves continuously casting a thin slab which is stored and rolled into a strip in the form of individual portions in several runs with return into the storage zone and with subsequent cooling, cutting, and coiling. The slab and the returned portion are stored simultaneously by combined coiling into an intermediate coil which is moved along the storage zone during coiling and during uncoiling of the portion of the slab and strip being rolled. An apparatus for carrying out the method has roller-hearth furnace, a storage in the form of a carriage provided outside the roller-hearth furnace for movement therealong, and a means for forming an intermediate coil from the slab and from the returned portion of the strip. The means for forming is installed on the carriage in the furnace so that the intermediate coil can move over rollers of the furnace during coiling and uncoiling.
A method for continuous production of hot-rolled strips, comprising continuously casting metal into a thin slab, storing the slab, feeding the slab at regular intervals from a storage zone in the form of consecutive portions, heating, rolling into a strip in the form of consecutive postions in several runs with return of the rolled portion into the storage zone, cooling, cutting, and coiling, characterized by storing the slab and the returned portion of the strip by their combined coiling into at least one intermediate coil which is moved along the storage zone during coiling and uncoiling of portions of the slab and rolled strip therefrom.
An apparatus for continuous production of hot-rolled strips, comprising a line including a continuous metal casting means for casting metal into a thin slab, a slab storage means, a through slab soaking-pit means, a rolling for rolling the slab into a strip in the form of individual protions in several runs with return of a portion being rolled to the storage means, a strip cooler means, a cutting means, and a means for coiling the rolled strip, characterized by the fact that the through soaking-pit means comprises a roller-hearth furnace, the storage means comprises at least one carriage provided outside the roller-hearth furnace for movement therealong, and a means for forming an intermediate coil of the slab and of the returned portion of the strip, said means being installed on the carriage and having a driven roll having a diametrical slot and a pair of drawing rollers along, and on either side of the roll positioned in the soaking-pit furnace over its rollers (11), the side walls of the furnace having longitudinally extending apertures receiving the ends of shafts of the driven roll and drawing rollers.
