Water cooling stretch for cooling wire rod or small sections of steel

Abstract

A water cooling stretch for cooling rolling stock coming from a roll train has several parallel and adjacently positioned cooling pipes having different diameters matching differently sized rolling stock. The cooling pipes are made of individual cooling pipe sections arranged successively in a straight cooling pipe arrangement, respectively. A cooling water supply of individual cooling head nozzle elements supplies the cooling water to the cooling pipe sections. Valve arrangements for controlling the supply of cooling water are provided. The cooling pipe arrangement has individual water box modules arranged between the cooling pipe sections, and the cooling pipe sections have inlet and outlet openings that open into the water box modules. The water box modules are fastened to a common water supply line moveable horizontally and transversely to a movement path of the rolling stock for moving the cooling pipe arrangements into and out of the movement path, as needed.

What is claimed is:  
     
         1 . A water cooling stretch for cooling rolling stock coming form a roll train, the water cooling stretch comprising: 
 several parallel and adjacently positioned cooling pipes having different diameters matching different cross-sections of the rolling stock and comprised of individual cooling pipe sections arranged successively to form a straight cooling pipe arrangement, respectively;    a cooling water supply comprising individual cooling head nozzle elements, configured to supply the cooling water to the individual cooling pipe sections, and further comprising valve arrangements configured to control the supply of cooling water;    wherein the cooling pipe arrangements comprises individual water box modules arranged between the cooling pipe sections and wherein the individual cooling pipe sections have inlet openings and outlet openings that open into the water box modules;    a common support on which the water box modules are fixedly connected, wherein the common support is configured to be moveable horizontally and transversely to a movement path of the rolling stock in order to move the water box modules and the cooling pipe sections into and out of the movement path of the rolling stock, as needed;    wherein the common support is a water supply pipe.    
     
     
         2 . The water cooling stretch according to  claim 1 , wherein: 
 each one of the water box modules receives individual ones of the cooling head nozzle elements so as to be exchangeably arranged in the water box modules between the inlet opening and the outlet opening of the cooling pipe sections connected to the water box modules;    each one of the water box modules receives one of the valve arrangements comprising high-speed switching valves correlated with the cooling head nozzle elements, wherein the cooling head nozzle elements are configured to be connected to the high-speed switching valves.    
     
     
         3 . The water cooling stretch according to  claim 2 , wherein a first one and a last one of the water box modules located at a beginning and an end of the cooling water stretch comprise exchangeable blow nozzle elements arranged downstream of the cooling head nozzle elements in the first and last water box modules.  
     
     
         4 . The water cooling stretch according to  claim 3 , wherein the water box modules comprise adjusting elements configured to adjust the cooling head nozzle elements and the blow nozzle elements.  
     
     
         5  The water cooling stretch according to  claim 3 , wherein the water box modules comprise pivotable and lockable covers.  
     
     
         6 . The water cooling stretch according to  claim 5 , wherein the covers have clamping elements configured to secure the cooling head nozzle elements and the blow nozzle elements.  
     
     
         7 . The water cooling stretch according to  claim 2 , wherein the water box modules comprise adjusting elements configured to adjust the cooling head nozzle elements.  
     
     
         8 . The water cooling stretch according to  claim 2 , wherein the water box modules comprise pivotable and lockable covers.  
     
     
         9 . The water cooling stretch according to  claim 8 , wherein the covers have clamping elements configured to secure the cooling head nozzle elements.  
     
     
         10 . The water cooling stretch according to  claim 1 , wherein the water supply device comprises pneumatic or hydraulic high-speed flaps arranged in the water box modules and connected to the water supply pipe.
