Cooling plate for an iron- or steelmaking furnace

Abstract

A cooling plate for an iron and steelmaking furnace includes a copper cooling plate body having at least one cooling duct for a cooling medium extending essentially parallel with the back of the cooling plate body. The cooling plate body further includes a preformed, externally accessible recess into which the cooling duct opens. A connection piece is utilized as a cooling medium connection on the back of the cooling plate body, while a formed piece fitted within the externally accessible recess forms a deflection surface for the cooling medium flowing from the connection piece into the cooling duct, or from the cooling duct into the connection piece.

1 . A cooling plate for an iron- and steelmaking furnace comprising:
 a copper cooling plate body with at least one cooling duct for a cooling medium, which extends essentially parallel with the back of said cooling plate body, and at least one preformed, externally accessible recess into which said cooling duct opens;   at least one connection piece for a cooling medium connection on the back of said cooling plate body; and   a formed piece that is fitted in said preformed, externally accessible recess in said cooling plate body so as to form a deflection surface for the cooling medium flowing from said connection piece into said cooling duct or from said cooling duct into said connection piece in axial extension of said connection piece.   
   
   
       2 . The cooling plate according to  claim 1 , wherein said formed piece is arranged in an axial extension of said cooling duct, said deflection surface being formed by one of its end faces in axial extension of said connection piece. 
   
   
       3 . The cooling plate according to  claim 2 , wherein:
 said cooling plate body has a front side, a rear side and an end face;   said recess axially extends said cooling duct into said end face;   said connection piece opens from said rear side into said cooling duct;   said formed piece is a plug, which is inserted from said end face into said recess and extends to the area where said connection piece opens into said cooling duct to form said deflection surface for said cooling medium in axial extension of said connection piece.   
   
   
       4 . The cooling plate according to  claim 3 , wherein said plug has a bevelled end which forms said deflection surface. 
   
   
       5 . A process of manufacturing a cooling plate for an iron- and steelmaking furnace comprising following steps:
 manufacturing a cooling plate body from copper or a copper alloy with at least one cooling duct for a cooling medium, which extends essentially parallel with the back of said cooling plate body, and at least one externally accessible recess into which said cooling duct opens;   providing at least one connection piece for a cooling medium connection on the back of said cooling plate body; and   fitting a formed piece in said preformed, externally accessible recess in said cooling plate body so as to form a deflection surface for the cooling medium flowing from said connection piece into said cooling duct or from said cooling duct into said connection piece in axial extension of said connection piece.   
   
   
       6 . The process according to  claim 5 , wherein said formed piece is arranged in an axial extension of said cooling duct, said deflection surface being formed by one of its end faces. 
   
   
       7 . The process according to  claim 6 , wherein:
 said cooling plate body has a front side, a rear side and an end face;   said recess axially extends said cooling duct into said end face; and   said connection piece opens from said rear side into said cooling duct.   said formed piece is a plug, which is inserted from said end face into said recess and extends to the area where said connection piece opens into said cooling duct to form said deflection surface for said cooling medium in axial extension of said connection piece.   
   
   
       8 . The process according to  claim 7 , wherein said plug has a bevelled end, which forms said deflection surface.
