    摘要: 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.

    摘要: For decreasing the width of a thin slab: a turning roll contacts the thin slab being conveyed at a certain contact angle to curve the thin slab; a tension applying device disposed in front and at the back of the turning roll, applys a tension to the thin slab forwardly and rearwardly in the direction of conveyance of the slab. Thus, the slab can be decreased in its width to a satisfactory section with no buckling loop forming portions for forming loops of the hot thin slab at the inlet and the outlet sides of the apparatus for decreasing the width of the thin slab absorb the intermittent proceeding of the hot thin slab in the direction of flow of the material. Thus, the continuous receipt and the delivery of the slab are made possible while the intermittent width decrease is performed, and the combination of the continuous casting equipment with the hot finish rolling equipment is materialized.

    摘要: A widthwise bend of an end of a hot-rolled elongate sheet-shaped metal product is corrected while it is hot. The correction comprises simultaneously:(i) holding the edges of the product at at least two positions longitudinally spaced along the product thereby to hold, at least laterally, a portion spaced from the bent end, and(ii) pushing the end portion laterally by means of a laterally moving member. The method may be performed while the product is continuously moving along a path. Both steps (i) and (ii) are performed by rollers rotatable about vertical axes.

    摘要: A multi-high rolling mill has upper and lower work rolls, upper and lower backup rolls, and an intermediate roll disposed therebetween. All of the work rolls, backup rolls and intermediate roll are arranged in a perpendicular direction. The intermediate rollers support the work rolls in the direction of a path of the work, and the support rollers support intermediate rollers. Each of the support rollers has a plurality of divisional rollers arranged in the axial direction of the support roller so that the axes of the divisional rollers are spaced from one another in the vertical direction. In other words, the divisional rollers are staggered alternately in the axial direction of the support roller. A space can be secured between each support roller and associated backup roll, to support the associated work roll in the substantially perpendicular direction. The support roller, backup roll, and intermediate roll do not contact each other. This enables the diameter of the work rolls to be minimized. Moreover, each intermediate roller directly supporting the associated work roll is reliably supported by two divisional rollers, the axes of which are spaced from each other.

    摘要: In a continuous hot rolling system, at least one melt-cut torch is set in a predetermined positional relationship with respect to a trailing end of a preceding hot material and a leading end of an adjacent succeeding hot material. An injected flow of cutting gas from the melt-cut torch is blown against a portion of at least one of the trailing end of the preceding material and the leading end of the succeeding material to melt-cut the portion. The portion extends from an end surface of the one end over a predetermined length. The trailing end of the preceding material and the leading end of the succeeding material are forced against each other and are butt-joined to each other. By doing so, there are produced joining surfaces superior in surface accuracy and high in temperature, to allow joining to be high in accuracy and strength. This joining may be made with respect to slabs before rough rolling, or may be made with respect to bars after rough rolling. Further, a slab manufactured by a continuous casting machine are reduced in thickness at a plurality of desired locations to form a plurality of thickness-reduced portions. Cutting is made at the thickness-reduced portions. The cut thickness-reduced portions are joined to each other. Furthermore, the ends of the respective materials after having been cut are reduced in thickness with the ends abutted against each other to form thickness-reduced portions. The thickness-reduced portions are joined to each other.
