The invention relates to a finishing train for finish rolling hot strip. It is the object of the invention to modify an existing finishing train in such a way that the surface quality of the hot strip produced is improved without, however, significantly increasing the use of energy during production. This is intended to enable the thin hot strip produced to be used even for applications with high demands on surface quality. This object is achieved by a cleaning nozzle which cleans the upper side of the exit table, thus ensuring that scale and/or rolling dust are/is removed from the exit table.

A device for producing strip material, such as a hot strip. The device includes lateral guide elements which are arranged on both sides of the strip material and, in particular, along a roller table having several rollers, and at least one rotating wear body on each side guide element. In order to minimize the wear of guide elements when transporting the strip material over a roller conveyor, a speed control device regulates a rate of speed of the at least one wear element. Further, a position control device is provided for setting an extended position of the at least one wear element. The position control device sends control signals to a positioning drive for extending the at least one wear body to an extended position.

A cemented carbide comprising 55-90 parts by mass of WC particles and 10-45 parts by mass of a Fe-based binder phase; the binder phase having a composition comprising 0.5-10% by mass of Ni, 0.2-2% by mass of C, 0.5-5% by mass of Cr, 0.2-2.0% by mass of Si, and 0.1-5% by mass of W, the balance being Fe and inevitable impurities, and containing 0.05-2.0% by area of Fe—Si—O-based particles.

A roller guide (1) for guiding stock in a longitudinal feeding direction (A) toward a pair of rolls for shaping the stock. The roller guide comprises a frame arrangement (2), a pair of guide rollers (3, 4) configured to, in a closed position, engage opposite surface portions of the stock,and positioning means for adjusting a lateral distance between the guide rollers. The roller guide further comprises detection means (13) configured to detect a longitudinal position of a piece of stock (20) with respect to the guide rollers. The positioning means is configured to adjust the lateral distance between the guide rollers in response to said detection.

The invention relates to a device for producing strip material, in particular hot strip, comprising: lateral guide elements (5) which are arranged on both sides of the strip material (4), in particular along a roller table (1) with several rollers (2), at least one rotating wear body (6) on each side guide element (5).

In order to further minimize the wear of guide elements when transporting hot strip over a roller conveyor, the invention proposes a speed control device (7) for setting a speed of the at least one wear element, a position control device (9) for setting an extended position of the at least one wear element and a positioning drive (13) for extending the at least one wear body to an extended position.

A guide roller configured to guide a wire to or from a work roller in a wire rolling line includes a rolling-element bearing having a rotatable outer ring, a fixed inner ring, and rolling elements between the outer ring and the inner ring. The outer ring has a profile configured to guide the wire on a radially outer surface thereof. The guide roller is configured as a double row preloaded rolling-element bearing and is installable as a finished component on a fixed shaft of the wire rolling line without adjusting the preload.

Apparatus to guide a metal product, the apparatus includes a support body (11). A plurality of support arms (12) are associated with the support body (11). A plurality of guide rolls (13) are installed rotating in an idle manner on the support arms (12) and define between them a roller guide gap (14) for the metal product. Adjustment devices (24) associated with the support arms (12) and adjust, independently from each other, the position of each of the guide rolls (13. Detection devices (19) detect the stresses induced by the metal product on the guide rolls (13).
