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, which slope downwardly toward a depressed central valley region. 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 roll well a metallic slab, with less fish tail and without hindering the rolling time, by edging a biting end-part of slab under the rolling reduction of maximum load and horizontally rolling its whole surface, and horizontally rolling only a thickness-increased part of the other part of slab, in reversingly edging the slab by calibered vertical rolls. CONSTITUTION:In reversingly edging a metallic slab by calibered vertical rolls, the biting end-part of slab is edged under the rolling reduction of maximum load, the whole surface of said end-part containing a thickness increased part caused by said edging is rolled by horizontal rolls. The other part of slab is edge under a prescribed edging condition, and only its thickness increased part caused by the edging is horizontally rolled. By this method, a rolling with less fish tail is performed without hindering as usual the rolling time, and a hot rolling process connected directly to a continuous casting process is operated in well cooporation with each other.

摘要： PURPOSE:To improve the yield of a steel strip in a continuous hot rolling line provided with a rough rolling stage provided with >=1 units of roughing mills and a finish rolling stage by rolling over the steel strip at the rough rolling rate within a specific range. CONSTITUTION:The billet emitted from a heating furnace 1 is scaled off under the light reduction in the transverse direction by a VSB3 and is rolled at the rough rolling rate within a 30-70% range by the 1st roughing mill 4. The steel strip is ejected to the outside of the line by a steel strip elector 11 and is rolled over 180 deg. by the taper roler mechanism of a steel strip rolling over region 12 so as to be returned again to the line, then the suceeding rolling is continued. The bottom shape at the front end of the steel strip and the fishtail shape at the rear end are annihilated or decreased, by which the discarding quantity at the termimal end of the strip is considerably decreased and the yield of the strip is incrased. The steel strip is rolled over preferably at the timing with the length of the strip is not so large rolling over may be repeated according to the kind of the steel.

摘要： PURPOSE:To effectively reduce the crop loss, by forming a cave along each of thickness and breadth at a couple of opposite side planes of at least either one of top and bottom of an ingot, and then by applying a usual blooming process to the ingot. CONSTITUTION:The side planes 10A, 10B opposite across the thickness at the top and bottom of a blank material 6 to be bloomed are subjected to plural reversing rolling passes performed by horizontal rolls 18A, 18B; as a result, recesses 12A, 12B are formed. The length DELTAL of thus formed recess is made about 200-400mm.. Then, side planes 20A, 20B opposite across the breadth are subjected to plural rolling passes performed by vertical rolls 8A, 8B in order to form recesses 22A, 22B. In a thickness range wherein the shape of a side of the ingot 6 causes a double barreling as a result of a thickness reduction, the ratio of the breadth reduction to the thickness reduction is regulated to 0.40-0.65; in a thickness range wherein the shape of a side plane causes a single barreling, said ratio is adjusted to
摘要翻译：目的：为了有效地减少作物损失，通过在锭的顶部和底部中的至少一个的两个相对侧平面上形成沿着厚度和宽度的每个厚度的洞穴，然后通过对锭进行通常的起霜过程。构成：在要开花的坯料6的顶部和底部的厚度相对的侧面10A，10B经受水平辊18A，18B进行的多次反转轧制; 结果，形成凹部12A，12B。这样形成的凹部的长度DELTAL为约200-400mm。然后，横向宽度相对的侧面20A，20B进行垂直辊8A，8B的多次轧制，以形成凹部22A，22B。在厚度减小的情况下，锭6的一侧的形状引起双重滚筒的厚度范围，宽度减小与厚度减少的比率被调节为0.40-0.65; 在其中侧面的形状导致单个滚筒的厚度范围中，所述比率被调整为<= 0.3。通过形成所述凹槽，通过对如此制备的锭进行喷霜处理，显着降低了由重叠和鱼尾产生的作物损失。
