摘要: A metallurgical device, in particular a casting installation, rolling mill or strip processing installation, including at least one machine part rotating about an axis, wherein an energy consumer that is in electrical connection with an energy source is arranged in the machine part. To supply the energy consumer with energy on a sustained basis in spite of adverse ambient conditions, the energy source is designed as a generator which is in connection with the rotating machine part for rotation therewith, wherein the generator is otherwise free of any mechanical connection with the metallurgical device and wherein the generator has a housing element, on which at least one eccentric mass arranged at a location that is at a distance radially from the axis.

摘要: There are provided a work-side position measurement device and a drive-side position measurement device for directly measuring positions of roll chocks in a rolling direction, and positions of upper and lower working rolls and upper and lower backup rolls in the rolling direction are adjusted to zero point or predetermined positions. Alternatively, a change caused in the strip wedge due to a minute crossing of the axes of working rolls and backup rolls is calculated, and the quantities of leveling of a work-side rolling reduction cylinder device and a drive-side rolling reduction cylinder device are adjusted to make the strip edge equal to or smaller than a predetermined value. Accordingly, the bilateral asymmetry (strip wedge) of the thickness distribution of a rolled material is easily adjusted even in the event that the positions of the roll chocks in the rolling direction are changed due to wear on various components.

摘要: A substrate (e.g., metal or non-metal sheet) can have multiple textures on a surface of the substrate. The various textures can be impressed or applied on the surface of the substrate by passing the substrate between multiple pairs of work rolls that each include at least one textured work roll for transferring a texture of the work roll onto the surface of the substrate. The pairs of work rolls apply the various textures on the surface of the substrate while maintaining a thickness of the substrate (e.g., with substantially no reduction in a thickness of the substrate). A single pass of the substrate between the pairs of work rolls can allow various different textures, patterns, or features to be applied to the surface of the substrate while the thickness of the substrate remains substantially constant.

摘要: An adjustment device for adjusting a roll in a roll support (13) of a roll stand includes a cylinder housing (2) that can be secured to a roll support (13), and a piston (1) guided to move translationally in and across the roll support. The position of the piston (1) can be determined via a travel measurement device (9) connected to a coupling rod (6) secured directly to the piston (1). The piston (1) has a guide element (3) extending from the piston head (4) into a bore in the roll rack and in the direction toward the travel measurement device (9). The coupling rod (6) is secured to the guide element (3). To reduce the sensitivity of the adjustment device to a tipping, the guide element (3) is guided in a guide opening (14) of the cylinder housing (2). A sliding guide (7) is provided for the coupling rod (6), which can be arranged on an end of a borehole (15) in the roll rack facing the travel measurement device (9).

摘要: A method is disclosed for determining the speed of a rolling stock, for example the belt speed of a rolling belt, wherein electromagnetic radiation in the microwave range is transmitted to the rolling stock by at least one transmitting and receiving device and the belt speed is determined on the basis of the reflected and received reflection signal in an evaluation device. A device for carrying out such method is also disclosed.

摘要: A detection device and a detection method for detecting a hole or a pinhole present in a material are provided. The detection device includes: an illumination unit irradiating light at one side of the material; a light receiving unit acquiring an image of the material at the other side of the material to output a detection signal; a detection unit determining whether or not the hole or the pinhole is present in the material using the detection signal; and an illumination control unit dividing the illumination unit into a plurality of regions and controlling the illumination unit to irradiate light having different intensities of illumination for each of the plurality of regions.

摘要: In a rolling process for reverse thermomechanically rolling an aluminum plate involving a plurality of rolling passes, identifying data are determined for thermally guiding the rolling process. Then a value of a state variable, from which a temperature of the aluminum plate can be deduced, is continuously measured and a pass schedule is determined for the rolling process on the basis of the value of the measured state variable and of the identifying data. The pass schedule provides for a rolling pause between at least two successive rolling passes, during which rolling of the aluminum plate is interrupted for cooling purposes.

摘要: The active vibration damping system of a rolling mill comprises a rolling stand and an adjustment system for the bending of the rolling rolls (1, 1′) having hydraulic actuators (2\2″, 2″′, 2iv) acting on the chock (20) of the rolling rolls (1, 1′) and hydraulic feeding circuits (7, 9, 11, 12) and injectors (8′, 8″, 8″′, 8iv), preferably piezoelectric injectors, directly inserted into the chambers (6\6″, 6″′, 6iv) of the hydraulic actuators (2′, 2″, 2″′, 2iv) with the advantage of exploiting the dampening effect resulting from the high- pressure oil injection.

摘要: Provided is a camber control apparatus and method capable of reducing camber of a slab sizing press (SSP). The camber control apparatus and method may calculates a camber amount through an imaging process and differently set zeroing of anvils at a work side and a drive side, thereby reducing camber. Thus, the camber control apparatus and method can reduce quality defects such as telescope, twist, wave, and roll mark, increase the lifetime of equipment by reducing a variation in load applied to the equipment, and minimize a cost caused by an equipment accident.

摘要: A billet (2) is rolled to a rod (3) in a rolling mill. The rod (3) exits the rolling mill with a finishing temperature (TE1). A rear laser measurement device (8) arranged downstream of the rolling mill detects the head end and the speed (v) of the rod (3). The detected speed (v) of the rod (3) is integrated to its length and an instantaneous length (L) of the rod (3) is determined. Dependent on the determined instantaneous length (L) of the rod (3), cutting commands (S) to a rear shears (5) arranged downstream of the rolling mill are provided for cutting the rod (3) in sections (6) of predetermined length (L0). The sections (6) of the rod (3) are cooled down in a cooling bed (7).
