摘要： A method and apparatus for reducing crop losses during slab and ingot rolling concerns the formation of a slab ingot having a specially configured or shaped butt end and optionally a head end as well. A special shape is formed by machining, forging or preferably by casting. The special shape at the butt end is imparted during casting by a specially shaped bottom block or starter block. The special shape of the bottom block is imparted to the cast ingot butt end. The specially shaped butt end of a slab shaped ingot is generally rectangular in shape and has longitudinally outwardly extending, enlarged portions (24), which slope downwardly toward a depressed central valley region (26). The lateral sides of the enlarged end portions and the depressed valley region carry transversely extending, tapered or curved edges. A similar shape may be imparted to the head end of the ingot at the conclusion of a casting run through the use of a specially shaped hot top mold or by way of machining or forging the cast head end. During subsequent hot rolling in a reversing roughing mill, the specially shaped slab ingot minimizes the formation of overlap and tongue so as to improve material recovery by reducing end crop losses and to increase rolling mill efficiency by increasing metal throughput in the mill.

摘要： PURPOSE:To prevent an H-beam from a causing a tongue after form-rolling by providing notches to the cutting pats of a beam blank for H-beam, cut into a prescribed dimension. CONSTITUTION:A flange 1A of one side of a beam blank 1 obtained by drawing a continuously cast mold, is linearly cut in the arrow (a) direction. Next, after opening a hole at the central part of the web 1B by cutting it in the arrow (b) direction, a flange 1C of the other side is linearly cut in the arrow (c) direction to form semicircular notches 13 at the cutting pats of web 1B. The web 1B is elongated in the longitudinal direction of beam blank 1 at the time of rolling an H-beam thereafter, and the notches 13 are vanished at the time of forming the H-beam, then respective both ends of web 1B and flanges 1A, 1C are trued up approximately. Thus a tongue produced conventionally is prevented by forming an H-beam in such a way, and a part to be discarded as a scrap is remarkably reduced.

摘要： PURPOSE:To reduce a remarkably fish tails generating at the front and rear ends of a metallic slab by subjecting the biting end of slab to a width rolling reduction larger in quantity than that other part is subjected to. CONSTITUTION:The biting end of a slab is subjected to heavy rolling rolling reduction by vertical rolls 2 having calibers placed at the inlet side, and the slab 1, excluding the biting end, is subjected to the rolling reduction allotted to the pass concerned. After horizontally rolling only a locally sheet-thickness increasing part of slab or both of said part and a nonincreasing part, the slab 1 is provided with a forcibly entering force between horizontal rolls 3 and vertical rolls 4 with calibers placed at the outlet side. In the sheet-thickness rolling by the rolls 4; the biting end of slab 1 is subjected to heavy rolling reduction, and the other part to the rolling reduction allotted to the pass concerned. The abnormally shaped parts generating at the front and rear ends of metallic slab 1 are remarkably improved by repeating reversibly this rolling thereafter.

摘要： There is provided a method for manufacturing a hot-rolled steel sheet having a large thickness and a large width, in which a steel sheet having a larger sheet thickness, a larger sheet width and a lower temperature can stably be cut at a cutting load equal to that of a conventional steel sheet having a usual sheet thickness, a usual sheet width and a usual temperature. In a rough rolling step, a shape of a crop portion formed at a front end of the steel sheet in a conveying direction is adjusted into a fishtail shape by width rolling of a width rolling machine and horizontal rolling of a horizontal rough rolling machine, the steel sheet is formed so that the shortest length L (mm) from a concave portion bottom to a convex portion top of the fishtail shape satisfies Equation (1) mentioned below, and an intermediate portion between the concave portion bottom and the convex portion top, defined as a desired cutting location, is cut: 2 X + 30 ‰¤ L ‰¤ 300 in which X is a maximum deviation (mm) of the cutting location of a crop cutting machine and 0 ‰¤ X ‰¤ 90.
