20080223100 | Method and Apparatus for Producing Strip Having a Variable Thickness - Disclosed is a method for producing strip having a variable thickness in its length direction, in particular a repetitive thickness variation, using a stand of a rolling mill, wherein the strip has a thickness D | 09-18-2008 |
20080302158 | Method and Rolling Mill For Improving the Running-Out of a Rolled Metal Strip Whose Trailing End is Moving at Rolling Speed - A method for improving the running-out of a metal rolled strip ( | 12-11-2008 |
20100050727 | Rolling Mill and Method for Controlling a Rolling Mill - A rolling mill, in particular, a cold strip tandem rolling mill, for producing a metal strip, with a number of stands is arranged in a tandem path, wherein, in a direction of production of the metal strip, a first stand is designed as driving stand and serves as inlet for a section of the tandem path, in which a primary thickness reduction of the metal strip occurs, and by corresponding control of the driving stand, an increase in the mechanical inlet tension of the metal strip can be achieved. In a method for controlling a rolling mill, in particular, a cold strip tandem rolling mill, for producing a metal strip, in a production direction of the metal strip, a first stand is controlled as driving stand, the driving stand achieving a significant increase in the mechanical inlet tension on the metal strip and a significant thickness reduction of the metal strip. | 03-04-2010 |
20120131975 | METHOD AND FORMING MACHINE FOR MANUFACTURING A PRODUCT HAVING VARIOUS DIAMETERS - The invention relates to a method and a forming machine suitable for manufacturing a product having various diameters from a workpiece, such as a metal cylinder or plate, in which the workpiece is clamped down in a clamping device, the workpiece and a first tool are rotated about an axis of rotation relative to each other, the workpiece is deformed by means of said first tool by placing the tool into contact with the workpiece and moving the workpiece and/or the tool in a direction along the axis of rotation. At least a second tool is placed into contact with the workpiece at a position behind the first tool, seen in the working direction, and the workpiece is also deformed by means of said second tool. Thus, parts of the workpiece that have been deformed by the first tool are deformed by one or more subsequent tools practically immediately. | 05-31-2012 |
20150367408 | CONTINUOUS CASTING EQUIPMENT - Continuous casting equipment includes a casting product reduction apparatus and a casting product drawing apparatus, the casting product reduction apparatus including a pair of casting product reduction rolls that sandwich and apply pressure to a casting product and being configured to apply reduction to the casting product, the casting product drawing apparatus being provided in a following stage of the casting product reduction apparatus and configured to sandwich and draw the casting product with a pair of casting product drawing rolls. At least one of the pair of casting product reduction rolls includes a large-diameter part that projects radially outward in an axial-direction center region and applies pressure to a width-direction center region of the casting product. The casting product that is subjected to reduction by the casting product reduction apparatus has a depressed part corresponding to the large-diameter part. At least one of the pair of casting product drawing rolls of the casting product drawing apparatus includes a depressed part supporting part that contacts with and supports the depressed part, and is driven by a driving mechanism An axial-direction length L | 12-24-2015 |
20160016216 | Drawing and Straightening Apparatus for Metal Wire, and Corresponding Drawing and Straightening Method - Apparatus for drawing and straightening at least a metal wire, comprising a drawing unit of the metal wire along a direction of advance which comprises a first motorized main roll, on part of the periphery of which first idle contrast rolls are disposed, with a smaller diameter than the first main roll. The apparatus also comprises a straightening only unit of the metal wire, independent from the drawing unit, disposed along the direction of advance and upstream of the drawing unit, the straightening only unit comprising a second idle main roll, on part of the periphery of which second idle contrast rolls are disposed, with a diameter smaller than the second main roll. | 01-21-2016 |
