Arrangement for cooling heat-treated wires

Abstract

An arrangement for cooling heat-treated wires comprises at least one cooling nozzle, which directs cooling fluid in a direction opposite to the travel direction of the wire, which along with the corresponding coolant channels are embodied in the form of perforations disposed in a planar parallelepiped, forming a central section. Side plates are arranged at both sides to laterally enclose the perforations. Coolant can be introduced into and extracted from the channels through apertures drilled in the side plates. A nozzle directing a separate fluid channel in the direction of wire travel can be embodied in the central region for pre-cooling of wires having a fluid coating.

1 . A device for cooling heat-treated wires, having a cooling nozzle that is penetrated by a wire bearing channel, whereby a coolant is supplied to the cooling nozzle via a lateral supply channel, and whereby the coolant runs through a tapering coolant channel in the nozzle and exits from the nozzle in the form of a stream, the coolant being directed obliquely toward the wire and against the running direction thereof, and being removed via a lateral drainage channel, and further comprising: 
 a nozzle element, in the form of a longitudinally extended parallelepiped, in which, from one longitudinal side, a wire bearing channel and the nozzles together with the coolant supply and drainage channels, are incorporated, and including openings for the supply and removal of the coolant, and    a cover plate joined to the longitudinal side of the nozzle element and being capable of removal in order to insert the wire in the wire bearing channel.    
   
   
       2 . The device in accordance with  claim 1 , further comprising the nozzle element being formed from a central part, from which the channels and the nozzle are bored out in the form of holes, with an adjoined side plate that contains the openings for the supply and removal of the coolant.  
   
   
       3 . The device in accordance with  claim 1 , wherein the nozzle is configured in the form of a double nozzle running conically from opposite sides toward the wire bearing channel.  
   
   
       4 . The device in accordance with  claim 3 , wherein, in each case, the bilateral coolant channels proceed from a flat inlet chamber, from which on both sides of the wire bearing channel several supply channels, are arranged side by side and are obliquely directed, and open out into the inlet chambers.  
   
   
       5 . The device in accordance with  claim 3 , wherein a collection chamber is provided for the exiting coolant is serially connected upstream of the nozzle, when seen in the running direction of the wire, from which several drainage channels, run obliquely oriented relative thereto, and which lead away from the collection chamber.  
   
   
       6 . Device The device in accordance with  claim 5 , wherein a hydraulic retarder is provided in the wire bearing channel.  
   
   
       7 . The device in accordance with  claim 6 , wherein an additional drainage channel is provided, in each case, between the hydraulic retarder and the wire inlet end, on both sides, of the wire bearing channel.  
   
   
       8 . The device in accordance with  claim 6  wherein the hydraulic retarder is provided in the region where the wire exits the wire bearing channel.  
   
   
       9 . The device in accordance with  claim 4  wherein the first nozzle, which operates in the form of a counter-current nozzle, has a second nozzle serially connected to it upstream of the first nozzle, whereby the second nozzle is arranged and oriented to present a mirror-image to the counter-current nozzle, and the drainage channels for the coolant are arranged between the two nozzles and, the associated supply channels are all disposed in the same central part.  
   
   
       10 . The device in accordance with  claim 9 , wherein a hydraulic retarder is arranged in the wire bearing channel between each nozzle and the end of the wire bearing channel.  
   
   
       11 . The device in accordance with  claim 10 , wherein coolant drainage channels are provided on the two sides of the wire bearing channel between the hydraulic retarders and the ends of the central part.  
   
   
       12 . The device in accordance with  claim 10  wherein the end pieces, which are joined to a wire inlet side and a wire outlet side of the wire bearing channel, each being in the form of flat profile sections that are divided at the openings through which the wire passes.  
   
   
       13 . The device in accordance with  claim 1  wherein a hydraulic retarder is provided in the region where the wire exits the wire bearing channel.
