    摘要： A continuous hot rolling method is available for continuously hot finish rolling steel pieces. The trailing end of a preceding steel piece and the leading end of a succeeding steel piece are cut by a drum shear which sandwiches the steel piece between its upper drum and lower drum, having cutting blades on the peripheries of the drums. The cut ends are heated to raise the temperatures thereof by high-frequency induction heating, pressed against each other to butt-join the cut ends. The joined steel pieces are then supplied to a rolling equipment. The trailing end of the preceding steel piece and the leading end of the succeeding steel piece are cut individually by two pairs of the cutting blades. One pair of the cutting blades has the obverses of the blades oriented in opposite directions in the obverse side and the reverse side of the steel piece. The other pair of cutting blades has the obverses of the blades oriented in the opposite directions relative to the former pair of cutting blades, while each steel piece is transferred to the same direction. The method according to the invention significantly reduces the displacement produced when the steel pieces are joined by applying transverse-type high-frequency induction, thereby realizing stable continuous hot rolling with no breakage of the rolled plate.

    摘要： A method for continuously hot-rolling steel pieces, includes butt-joining the rear end of the preceding steel piece and the leading end of the succeeding steel piece, then finish-rolling the butt-joined steel pieces by supplying a continuous hot rolling facility provided with a plurality of stands having a bending function of a work roll. The method involves estimating the variation of the rolling force occurring during rolling the joint of the steel pieces at the non-stationary zone caused by said joint, calculating the changing bending force of the work roll during rolling the joint of the steel pieces from the estimated variation of the rolling force, and determining the pattern for changing the bending force taking account of said changing force, and rolling the joint of the steel pieces by regulating the bending force in response to said pattern over at least one stand, while tracking down the joint of the steel piece immediately after joining.

    摘要： Herein disclosed is an endless hot rolling method using a hot strip mill substantially composed of a roughing mill and a finishing mill having a roll bender and a roll shifter to continuously roll sequentially joined different rolling materials. The method comprises the steps of: calculating a roll shift range in an axial direction for each rolling material so as to provide a desired crown; determining a rolling sequence so as to obtain a common roll shift range for each pair of neighboring rolling materials; connecting a preceding material at the tail end thereof to the head end of the succeeding material, between the roughing mill and the finishing mill; shifting the rolls during transition from the preceding material to the succeeding material so that the roll position corresponding to the joint of the two materials is within a common roll shift range for the materials; and changing the roll bending load in accordance with the roll shift pattern so as to achieve the desired crown of each material. If the width of a common roll shift range for all the materials is at least 50% of the width of the individual roll shift ranges, rolling can be continuously performed without shifting in an axial direction rolls.

    摘要： A sheet crown control method and apparatus for use in endless rolling in which consecutively fed sheets are joined to each other to be continuously rolled through a rolling equipment line. The rolling equipment line includes a junction device for joining consecutively fed sheets to each other, a plurality of stands arranged in tandem on the downstream side of the junction device and having a roll bender load adjusting mechanism and a roll crossing mechanism. The roll cross angle of rolls incorporated in a stand of each rolling mill is set at a predetermined value beforehand if there is a roll cross angle that will enable a target sheet crown to be applied to each sheet and the roll bender load of each stand is adjusted on-line, thereby effecting sheet crown control. Rolling also may be performed while adjusting the roll cross angle of rolls incorporated in stands of each rolling mill on-line together with the roll bender load. The roll bender load and the roll cross load may be adjusted in a transition region where a junction between sheets exists or in a stationary region where sheets of the same material follow one after another.
