    Abstract: PURPOSE:To decrease fishtails without promoting the width reduction in leading and tail end parts by press-forming the part apart by more than a specific distance from the end face to narrow width then applying broadside screw down and thickness screw down in the end parts in the longitudinal direction of a slab. CONSTITUTION:A pair of press heads 1 for broadside screw down moved forward and backward in the width direction by means of oil hydraulic cylinders 2 are provided to the front stage of rolling mills. The part apart by a distance (l) from the end face E of a slab S is press-formed to narrow width by the heads. However, the end part S1 is not subjected to edging. Namely, the distance (l) is at least the distance at which at least said end part S1 can retain the original shape. Then, the end part E forms the shape wherein the central part in the width direction overhangs. Next, when such slab S is rolled with rolling mills of the rear stages, the end part S1 forms a fishtail, but it is decreased considerably as it is offset by the overhanging effect of the central part in the width direction. Since the end part S1 is not press-formed, the width reduction hardly occurs.

    Abstract: PURPOSE:To reduce crop losses by cutting the front and rear ends of a slab into projected and recessed plane shaped respectively and edging the slab between a pair of anvils opened and closed periodically. CONSTITUTION:A gas cutter provided with a computer for controlling the speeds in both casting and width directions is disposed at the outlet side of a continuous casting machine. The front and rear ends of a slab are previously cut into projected and recessed shaped respectively to form a continuously cast slab 2 by synchronizing the speeds of cutter in both directions with a continuous casting speed. Anvils 1, 1 are periodically opened and closed at an amplitude 2(a) and a frequency (f) by synchronizing their motions with the casting speed, and the minimum distance between them is set to a prescribed width W1. The slab 2 is fed between the anvils 1, 1 and is pressed by a whole length edging system. In this way, the cut off part of the front and rear ends of slab 2 are reduced, that is, the crop loss is reduced.

    Abstract: PURPOSE:To prevent generation of a fish-tail in a slab receiving a rolling process by rolling the edge of a slab in the direction of its breadth so as to reduce the breadth, and at the same time, by rolling the slab so as to give a gradually reduced rolling reduction to the breadth of the part continuing to said edge toward the longitudinal middle zone. CONSTITUTION:An edge of a slab 1 is rolled in the direction of breadth by a press die 6 parallel to the end plane of the slab 1. At the same time, the part continuing to said parallelly rolled edge toward the longitudinal middle zone, is rolled by a tapered press die which gives a breadth reduction gradually diminished toward the middle zone. By the present method, a tail end restrainer becomes needless, a preliminary formation can be performed without generating laps, and the generation of a fish-tail by a rolling process is prevented. The shape of the die 6 to be employed by the present edging process is selected so as to place the neutral point of deformation of the slab 1 by a press work behind the border between the parallel zone 6a and the tapered zone 6b.

    Abstract: PURPOSE:To reduce the local wears of the sliding parts of guides and cylinders, etc. at the time of reducing the width of a slab by conforming the center of a pressing force applied to a press tool to the loading center of said tool used for pressing the slab. CONSTITUTION:The position of a press tool 16 is detected by a position detector 52, the amplitude of the expansion and contraction of tool 16 and the method of expansion and contraction of the tool 16, and inputted to a computing unit 50. The computing unit 50 computes the amount of deviation between the center of loading and that of a pressing force. The press tool 16 moves when the driving force of a motor 46 is transmitted to a screw shaft 30. The position of tool 16 is detected by the detector 52 and is fed back to a controller 48, to stop the tool 16 at the position where the loading center coincides with the center of pressing force. Thereafter, the positions of tools 16, 16 in the sheet-width direction of slab are set by a sheet-width adjusting part 76 to reduce the width of slab 10 by expanding and contacting the tools 16, 16.
