COOLING SECTION WITH VALVES AND PRESSURE VESSELS FOR PREVENTING PRESSURE SHOCKS
A device for cooling a metal rolling stock (1) rolled in a rolling train, having multiple cooling devices (4), to which water (5) is supplied via a respective branch line (7) and by means of which the water (5) is applied to the rolling stock (1). The branch lines (7) are equipped with a respective valve (8), by means of which the water flow flowing through the respective branch line (7) is adjusted. Each of the valves (8) is paired with a drive (9), via which the respective valve (8) is actuated. The cooling devices (4) form multiple groups, each of which is paired with a dedicated pressure vessel (10) in a proprietary manner. Each pressure vessel (10) is connected to a respective feed line (12) at a respective connection point (11), and the water (5) is supplied to the branch lines (7) of the cooling devices (4) of the corresponding group via said feed line. When viewed in the flow direction of the water (5), each connection point (11) is arranged upstream of the valves (8) of the respective group of cooling devices (4).
High efficiency stripper nozzle
A high efficiency stripper nozzle, with a through hole configured to be connected to the through hole of another nozzle, guide, or nozzle, which comprises several radial channels that pass through the nozzle from the perimeter zone to the hole at its entrance zone. The nozzle may be divided into several pieces which can be connected together in a removable way and replaceable, which may form the radial channels between them with different sections and angles with respect to the axis of the hole. The radial channels may contact externally with an opening located on one of the surfaces of the nozzle or on one of the surfaces of the nozzle to which the nozzle is connected.
HIGH EFFICIENCY STRIPPER NOZZLE

THREEFOLD ROTATIONALLY SYMMETRICAL STAND HOUSING HAVING INTEGRATED OPERATING FLUID LINES
The present application relates to a stand housing (10) for a stand (1) for rolling metal rods, wires or pipes along a rolling axis (19), wherein the stand housing (10) comprises an outside (12) having six side surfaces (14.1-14.6) which, viewed along the rolling axis (19), form edges of a regular hexagon, an inlet side (15), and an outlet side (13). In this case, at least one water feed opening (43.1, 43.2, 43.3) is arranged on three of the side surfaces (14.1, 14.3, 14.5) that are not adjacent in each case, which opening is designed to conduct water through the interior of the stand housing (10) to a water outlet opening (42.1, 42.2, 42.3) in the outlet side (13) or in the inlet side (15).
