An aluminum hot strip rolling mill including a multi-stand tandem finishing rolling train (2), at least one winding reel (8) arranged downstream, in the rolling direction, of the multi-stand tandem finishing rolling train, a cooling section (4) provided in the outlet region of the aluminum hot strip rolling mill, and at least one trimmer (6) paired with the multi-stand tandem finishing rolling train and arranged downstream, in the rolling direction, in the rolling direction, of the multi-stand tandem rolling mill train.

Disclosed within is a slit section pass formation unit having a pair of rolls and a de-ribbing means, where the pair of rolls has a roll profile configured to produce a pair of slit rods with symmetrical dimensions, the pair of slit rods connected via a rib, and the de-ribbing means to remove the rib in its entirety forming a first slit rod and a second slit rod.

A laser cutting method for a steel strip, includes cutting an end in a width direction of the steel strip including a joint obtained by joining a rear end of a preceding steel strip and a front end of a following steel strip by using a laser beam, wherein the steel strip is cut such that an interval between pieces of dross having an aspect ratio of 1.0 or more is set to 1.0 mm or more and an interval between dross having an aspect ratio of 1.0 or more and dross having an aspect ratio of less than 1.0 is set to 1.0 mm or more in the end in the width direction after cutting.

A rolling stand for rolling a hot aluminium strip, having at the outlet side, in this order, a trimming device that cuts the metal strip from both sides such that only the remaining central region of the metal strip is fed to the downstream devices; a front deflection roller that deflects the metal strip away from a direct connecting line between the rolling stand and the rear deflection roller; a measuring assembly that has a mechanical excitation device that excites the metal strip to mechanically oscillate in the direction of its thickness and a measuring device that senses, for a plurality of regions of the metal strip lying adjacent to one another in the direction of the width of the metal strip, the amplitude of the excited mechanical oscillation of the respective region; and a coiling device that has a rear deflection roller upstream of a coiler.

A slitting machine for threading scrap material includes first and second arbors; rotary knives disposed on each of the first and second arbors; and a pair of notching modules positioned on opposite ends of the first and second arbors. The notching modules each has a pair of shear knives for making multiple cuts in a strip of material passing through the slitting machine forming notches to enable threading of material to scrap chutes from the slitting machine.

Methods for making Ta sputter targets and sputter targets made thereby. Ta ingots are compressed along at least two of the x, y, and z dimensions and then cross rolled in at least one of those dimensions. A pair of target blanks is then cut from the cross rolled ingot. The resulting targets have a predominate mix of {100} and {111} textures and have reduced B {100} and B {111} banding factors.

Provided is a shaping device for a roller electrode for seam welding that prepares shapes for a first roller electrode and a second roller electrode attached to an arm of a robot. This shaping device is provided independently from the robot and disposed within rotational range of the arm, and is provided with a first roller and a second roller that are disposed on a line orthogonal to a line joining the rotational centers of the first and second roller electrodes and are in contact with the outer circumferences of the first and second roller electrodes.

Disclosed within is a slit section pass formation unit having a pair of rolls and a de-ribbing means, where the pair of rolls has a roll profile configured to produce a pair of slit rods with symmetrical dimensions, the pair of slit rods connected via a rib, and the de-ribbing means to remove the rib in its entirety forming a first slit rod and a second slit rod.

Generally described, one or more aspects of the present disclosure relate to methods, systems, and devices related to pre-straining bare lanes of a multilane electrode with a system for calendering a multilane electrode including a pre-strain roll device including a plurality of pre-strain rollers and a pressure roller forming a pre-strain nib and a calender roll device comprising a pair of calendering rollers forming a calendering nip positioned downstream from the pre-strain roll device.
