摘要： In performing cold rolling on a seamless pipe as a mother pipe, it is possible to inhibit the generation of metal chips from the end portions of the mother pipe, and to prevent the formation of indentations therein that may be caused by the metal chips to thereby provide good surface appearance. This is made possible by using a mother pipe (1) having end portions at the cold rolling starting side and finishing side that have been R-chamfered, at each outer edge and at each inner edge, such that (T0−T1)/2≦R≦T0/2 is satisfied, where R is a radius (mm) of the R-chamfer on the outer edges and the inner edges of the end portions, T0 is a wall thickness of the mother pipe, and T1 is a wall thickness of the pipe after cold rolling.

摘要： The invention relates to a mill train (1) for milling a strip-type product to be milled (10). Said mill train comprises a number of roll stands (2) which are successively arranged in a milling direction (x) and which can be respectively pivoted about a rotational axis (18) which is essentially perpendicular to the milling direction (x). The aim of the invention is to maintain a belt run which favors a pre-determined milling result, in an especially simple and reliable manner. According to the invention, a control value (S) is pre-determined for the pivoting angle of a roll stand, or of each roll stand (2), according to the determined contour of the strip end (30) of a product (10) which has already been milled. According to the invention, additional control elements can also be used.

摘要： The invention relates to a method and an installation for hot-rolling strips using a reversible Steckel rolling frame (8), each side of which is equipped with a respective furnace coiler (9, 10) and a driving mechanism (17,18), provided between the furnace coiler (9, 10) and Steckel rolling frame (8). The aim of the invention is to crop particularly thin, hot strips. To achieve this, the strip is cropped during the reversible rolling process by a single pair of flying cropping shears (20), positioned between one of the driving mechanisms (17) and the Steckel rolling frame (8). The cropping shears comprise in particular a drum blade.

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.
摘要翻译：用于在板坯和锭轧制期间减少作物损失的方法和装置涉及形成具有特殊构造或成形的对接端以及任选的头端的板坯锭。通过加工，锻造或优选通过铸造形成特殊形状。在特殊形状的底部块或启动块铸造期间，在对接端的特殊形状被赋予。将底部块的特殊形状赋予铸锭对接端。板状铸锭的特殊形状的对接端通常为矩形形状，并且具有向下朝向凹陷的中心谷部区域向下倾斜的纵向向外延伸的扩大部分。扩大的端部和凹陷的谷区域的横向侧面具有横向延伸的，锥形的或弯曲的边缘。通过使用特殊形状的热顶模具或通过加工或锻造铸造头端部，在铸造过程结束时，可以向铸锭的头端施加类似的形状。在倒车粗轧机的后续热轧过程中，特殊形状的板坯最小化了重叠和舌头的形成，从而通过减少作物损失来提高材料回收率，并通过提高轧机的金属产量来提高轧机的效率。
