ABSTRACT:
A continuous steel hot-rolling method and apparatus for successively bonding a plurality of steel pieces of a predetermined length and maintained at a high temperature so as to form a continuous train of the steel pieces for roll by a rolling mill. The apparatus includes a holding device for holding a trailing end of a preceding steel piece and a leading end of a succeeding steel piece. A device is provided for shearing the ends of the steel pieces while the ends are held by the holding device. A device heats the sheared trailing end of the preceding steel piece and the sheared leading end of the succeeding steel piece to a predetermined temperature, with a device being provided for driving at least one of the preceding and following steel pieces along a travel path of the steel pieces to press and bond the heated trailing end surface of the preceding steel piece and the heated leading end surface of the succeeding steel piece. A carrier carries all the above devices and is disposed upstream of the rolling mill for movement along the travel path of the steel pieces being bonded.
