摘要： A working roller for a rolling mill for laminating a sheet of alkali metal or alloy thereof into a film is disclosed. The working roller has a cylindrical center portion defining a central axis, the center portion having an outer surface defining a lamination surface; and first and second frustoconical portions extending from first and second ends of the center portion respectively. When the central axis is straight, an angle between the outer surface of the center portion and an outer surface of each of the first and second frustoconical portions is less than 0.05 degrees. A width of the center portion is greater than a width of each of the first and second frustoconical portions. The width of the center portion is less than a sum of the widths of the first and second portions. A rolling mill having two such working rollers is also disclosed.

摘要： A roll stand for the rolling of rolling stock, especially metal products. The roll stand includes at least two chocks for mounting at least one roll, the roll being rotatably mounted in the chocks by its two cylindrical roll necks. A cylindrical neck bushing is arranged on the roll neck with radial play. A rotationally fixed annual axial bearing is axially offset from the neck bushing. The bearing arrangement for the roll necks in the chocks is formed as a plain bearing, preferably a hydrodynamic oil film bearing. When subjected to a load in a rolling process, the neck bushing moves and deforms not only in the radial direction, but also in the axial direction.

摘要： A method for the production of a cold-rolled profile having at least one thickened profile edge made of a metal strip is provided. For this purpose the metal strip is guided through at least one clamping nip formed by at least one guide roll and at least one lateral edging roll, wherein the roll axis of the guide roll is disposed parallel to the web level of the metal strip, while the roll axis of the edging roll is disposed transverse to the roll axis of the guide roll, and is lined up at an angle to the strip level such that in addition to the upsetting force exerted by the edging roll onto the strip edge a clamping force is also applied that acts on the side of the metal strip facing away from the guide roll. The edging roll may be configured in steps, and surrounds the web edge at least on the side of the metal strip facing away from the guide roll.

摘要： A rolling mill for rolling pipes on a mandrel (40) is formed by an alignment of rolling units according to the invention, each rolling unit comprises an outer annular structure (2) formed by at least two plate-shaped elements (3) connected rigidly to one another and housing a roll carrier (10) on which the rolling units (27,28,29), supported by respective pivoting lever arms (19,20,21), are disposed. Each roll carrier (10) can be removed transversely from its rolling unit which, for this purpose, is provided with guides (15) in addition to a loading-unloading device (50) on which the removed carrier is placed. The outer annular structure (2) enables the rolling unit and the corresponding rolling mill better to withstand the radial stresses produced during working, the replacement of the rolls of the respective carriers (10) at the same time being simplified by virtue of their lateral movement.

摘要： A heat treatment furnace for fiber for heat-treating a fiber bundle (yarn) formed of many continuous filaments in hot gas while running the yarn. The heat treatment furnace has a plurality of heat treatment chambers provided in a furnace body. The temperature in each individual heat treatment chamber is independently adjusted to a temperature which is different from the temperatures in the other heat treatment chambers. Thereby, the heat treatment furnace can be made small and is able to heat-treat fiber efficiently.This heat treatment furnace is useful, particularly, as a heat treatment furnace (an oxidizing heat treatment furnace, or a oxidizing furnace) for producing an oxidized fiber needed to produce a carbon fiber. A polyacrylonitrile-based fiber bundle (yarn), that is a precursor fiber bundle for producing an oxidized fiber, passes through a zigzag yarn path, and passes through the heat treatment furnaces, in each of which temperature is independently adjusted to a temperature that is different from the temperatures in the other furnaces. An oxidized fiber bundle (yarn) is thereby produced.The zigzag yarn path in the heat treatment chambers for the oxidizing heat treatment is established by a combination of a plurality of yarn guide rollers provided outside the furnace body. Each yarn guide roller has, on its peripheral surface, a yarn guide groove for guiding a yarn. The yarn guide grooves have a specific cross-sectional shape whereby the cross-sectional shape of the yarn to be supplied into the heat treatment chambers for the oxidizing heat treatment is adjusted into a flat generally rectangular shape. Heat accumulation in the yarn being heat-treated is thereby reduced.
